SG explosives? As in nukes? Everything solid that we have on Naquadah enhanced nukes/explosives is slightly above gigaton level. Naquadriah nukes are in the high triple-digit gigaton figure, perhaps even teraton.
Why wouldn't it? Even Atlantis' shields had a definite capactiy, one which could be overloaded after several days of bombardment. This is very similar to Trek shields, which can be overloaded after a specific time. The more wattage, the shorter the time it should take to knock out the shields.
I think you're missunderstanding each other. Either that or i'm the one out of sync. What i think Mr. O is saying is that SG shielding can deflect a certain amount of energy and that the time involved is irrelevant.

A simple demonstration. If a shield is capable of taking 1MJ of energy (arbitrary number) then it can take that over a an hour, or during the fraction of a second, the time makes no difference. There is no 'peak' energy dissipation the shields can manage.

Of course, i could be wrong in my interpretation of what the two of you are trying to get across.

Torpedoe focus

I assumed that since even we can focus some contemporary nukes, low yields however atm, a civilisation that uses all sorts of babble and tougher materials would have no problem to make even megaton level torpedoes slightly focused.
Focusing slightly is one thing. I would imagine that 50% or so is about where they should be. Even if we were to accept this without any evidence, it would mean that torpedoes are still no less than around 100 or so megatons for an average range, which seems to also be around the average range for SG explosives.
Dialogue pointed out later on shows that a ship can be endangered by its own torpedoes fired at an enemy. That's radiation and propagation of the torpedoe's casing in every single direction.
There's not a single trace of focus there.
So on the good side for you, it would double any yield calculated for the explosion of a torpedoe on the surface of a hard natural target.
Possibly, or if you are right; that cannot focus all of the energy, and there will still be enough excess energy released from the combined torpedoes' explosion to cripple the E-D regardless.
"An explosion this close to the ship" though.
Apparently, 50% of a spread of torps at max yield - which was what Picard ordered when able to do so - that close to the ship, would cripple it. It's not illogical. That's actually what you'd expect since torps hitting shields will exactly do that, bare the distance separating the E-D from its target in that case, which was "this close".







Stargate shields, the non relevance of wattage and power of weapons
Please point to evidence that wattage has a definitive relevance.

Of course, it will wear down over time, but not the times that are relevant in most spacebattle scenarii.
Above all, wattage is not relevant in the sense that delivering the same energy but faster won't make the attack more efficient, as it won't add extra damage like a bonus.
Again, the way you explained it earlier, is very similar to an ST disruptor bolt. A quick blob that impacts and disipates over shields or armor. Perhaps you can provide a better discription, or perhaps screencaps to illustrate what you mean?
I guess it's the same story about those disruptors. A blob approaches the shield. The frame later, it's gone, and the shield is fizzling at the point of impact, like it does for anything that hits it.





The Die is Cast: O' Mama!
Thank you.
I don't understand the assumptions behind his calcs though, nor how they're relevant to the episode.
We're still talking about TDIC, right?
Why does he assume the torps only providing 10% of the damage, since in that case, the assault fleet would have likely put their torps on maximum yield, and in all logic, represent an equal or likely larger level of firepower than phasers?
Plus what's that story about fires and other whatnots?
Where's the part about the crust destruction?
Thirty percent of the planet's crust in TDiC was said to have been destroyed in the opening volley. His assumptions are perfectly valid given he is going to extreme lengths to be conservative by assuming that the fireballs and shockwaves are not destroying the crust itself in any way, and that the torpedoes are providing only a small relative fraction of the total explosive yeild. Nothing too hard to understand, and it still shows how photon torpedoes can be vastly more powerful than phasers, which ties in with "Masks", and the idea that even at one or two gigatons for a phaser, a torpedo or torpedoes will still outrange it.
I beg to disagree.
He's talking about fire... like there's anything on that rock to burn. Where? Last time I've seen an episode about the founders' world, there was only one little tinny winny island sticking out, barren of any vegetation. As for the rest of the surface, I don't know, but if that world was covered at 99.99999% by founder juice, nothing worth of a firecamp could grow underneath.

He also goes to assume that a certain type of weapon, torpedoes in that case, which for all intents and purposes would have been set to maximum yield in that case, only represented like 10% of the total damage that occured from all weapons being fired in the opening volley, pretty much against the very statement you took (from an episode) about the ratio between phasers and torps.

His assumptions are nothing more than attempts to lower the figure beyond ridicule up to the point where it doesn't fit facts and logic, but somehow would make the event acceptable.

The only way to accept this is to assume that by "crust", they meant "surface", which is the (flawed and unsound) premise of his calcs. Of course, saying surface would have been much clearer and technically correct, if that was really what happened.

The point is that he's blatantly ignoring specific informations from the episode (like the flawed and nonsensical computer estimations) to make his nerfed premise valid.

I suppose that if destroying the crust is liting fires on the surface, then destroying the mantle is setting fire on its surface... oh wait, how are they going to even reach the mantle as a whole with weapons that only lit fire on the surface?...

So basically, we're again with calcs that are correct but do not fit the elements from the show. They're unacceptable.

You have to be totally honest and play with hands on the table. What info are you ready to neglect from that episode? How far are you ready to go before it fits with former events?
I give you that they are veterans.

But the guy who programmed that computer is a total moron. 1 hour to blast the crust, and only 6 hours to destroy the... mantle?
- First, how do you even destroy a mantle? Is it vaporization? They're going to vaporize the mantle over 6 hours? You really believe that?
No, that is a fallacy. There is no indication that the information was false, or that the people running the computer analysis were idiots.
It's not technically possible. How can it be correct? You're going to have a hell of a job to prove the estimation is correct.
- Secondly, how can you expect to do whatever to a mantle in 6 hours when your weapons still require 1 hour to destroy the crust? Just check Wong's calculator. Even if it was not totally accurate, check Wong's asteroid calculator. Try a diameter of 23.73 m. You end with 16.8 kilotons necessary to reach the melting temp, for hard nickel-iron, and 100 kilotons to directly reach vaporization.
Lots of conditions can lead to that. The crust of the Founder's homeworld might actually be very thick (as planetary bodies like the Moon and Mars are believed to have), and the mantle relatively thin, ect.
These are small bodies. Less pressure. Less heat. It would be an almost dead planet. Not even talking about atmosphere, which seemed pretty breathable. The gravity was Earth like.
Choosing Mars and Moon to only take the interesting bits is cherry picking.

It also means a cooler mantle, thus more energy required to "destroy" it, whatever that's supposed to mean. It does in no way ease your job at making sense out of that.

Plus with a cross section of Mars, the mantle strate would represent 50% of the planet's average radius, with the crust only 1.4%.
I fail to see how taking Mars as an example is going to make the computer estimation even more logical.
So not only do you need vastly more energy to vaporize even something that's already molten, but if you take Earth as an example, the mantle largely outweighs the crust by an insane volume, since largely less than 1% of Earth's volume corresponds to the crust, while 70% are occupied by the mantle.
Who said that "destroy" equals "vaporize"? No one one. For all we know they are blasting holes in the crust over time, then blasting off chunks of the mantle with each volley/
Chunks of the mantle?
Plus the yields Graham got wouldn't even approach a minuscule fraction of escape velocity.
- Finally, this computer estimation is even more crap, since the opening volley destroyed 30% of the crust, by the same dialogue.
Let me check. Ah, destroyed in a couple of seconds at best, according to events.
Say what?


A conservative planning estimate on their part when you look at the context of them carrying out the operation while the nearest Jem'Hadar bases were some seven hours distant.
Oh, I see. So if 1 hour for crust destruction is measly reduced to something like one or two minutes (a couple of seconds to destroy 30% of the crust, remember), we're left with, what? 12 minutes max to destroy the mantle, if not 6 minutes...

Sure.
Mind you, Stargate has a case like that. In Redemption, they believe that a single 1 or 2 gigaton underground blast will destroy all life on Earth.
Totally absurd.
So? How does that equate to TDiC in any real way? None.
It's extremely relevant since this statement in Redemption is as canon as that TDIC. None make sense however.
There is no evidence that they were wrong, and analysis by Starfleet saw no problems with the plan, either. Until we have hard evidence, there is no reason to assume the Tal-Shiar and Obsidian Order planners were idiots.
-Mike
I'm pointing out plenty of discrepancies since several posts, and you're brushing them with the back of the hand by stating the characters can't be mistaken, they qualified and veterans, etc.
Forgetting, for a moment, that writers, just like VFX guys, are not omnipotent and not always right.





Masks, funky ice fusion
Wrong wording. Sorry. My point is that a later shot with the alien structure in the background precisely shows that it's bigger than the Enterprise.
However, a shot from the tractor beam holding the E-D tight reveals that the asteroid woudn't be more than 3 km wide at best.
It took me a while to find the image you're refering to. The small section of the D'Arsay archive structure is at least 1.5 km tall, assuming that the tractor beam in that image only enlarges out to twice it's size over the distance and therefore the E-D is practically sitting on top of the archive. I think it better to use the phaser beam when scaled to the comet, and not to an unknown quantity like the D'Arsay tractor beam, and the distance from the archive to the E-D.

At any rate, a 3 km wide comet would be actually substantially larger than Graham or anyone else's estimate, and that means that even with only melting occuring, the phasers are still doing a considerable amount of work.

According to Wong's calculator, the melt energies alone, never mind vaporization energies, is still around 1.8 gigatons of energy (163 megatons a second for an 11 second phaser firing).
I'd also consider the volume of the archive itself. As the E-D barely started firing on the comet, the main tower's roof was already sticking out.
I've not claimed it should have.
Plus visuals tend to show that the beam wasn't that spread after all. It still was extremely focused.
The beam is shown widening. We do not see what happens after the scene cuts away, so to claim that the beam stays at the same state through the whole firing is a bit disengenous. It might, but since the goal was to not harm the core of the comet and spreading the phaser energies out in a wide beam, it is only logical that the beam was widened as the firing went on.
Yes, it is shown widening, but not by that much.
Using the beam's width as a yardstick (6m), assuming it has not immediately widened by the first frame, is how you obtained the size of the comet, right?
This was not my point.

Besides, the station is largely doused in the phaser beam.

My point is that regarding the way energy was imparted, the way the ice melted is completely nonsensical.

The phaser hits the core. The energy will be dispatched as a radiating tunnel down to the core. The other side of the comet will only be molten by the energy radiation.
In all logic, the last bit to go should have been located on the hidden side of the station, opposite to the E-D, and should have looked like a stalactite.
Even more, since the beam was hitting the station as large, most of the energy was to be found there.
Yet, the last bit to melt is the ice surrounding the station, and above all it shrank inwards, towards the station.
The phaser did not hit the core immediately, if at all. It clearly starts at the surface, and as the scene cuts away, the archive is just starting to become exposed, but there is still some (glowing) material between the beam and the archive structure. Given that they are not "tunneling", but apparently removing the outer layers of the nucleous' ice to expose the archive, it only stands to reason that they are using the wide beam to cover a large outer layer all around, possibly removing more on one side, but still keeping things fairly even over the course of the operation.
Ok, but that doesn't explain at all the funky physics. Ice, when melting, does not shrinks towards the hotest point.
Otherwise putting an icecube on a warm room would make the icecube dramatically inflate to many times its initial size, and have the water... magically hover in the air.
Actually, it's totally surprising and physically impossible. Even more if as you suggest, the structure was heated up a bit to radiate heat, which would be the only solution to still find a source of heat to melt the remaining ice. The point is that no ice should have actually remained on the station. The last bits of ice to melt should have actually been the ones the more distant from the core, from the station.

If you watch the video, you'll see how this makes no sense.
I did watch the episode, several times, in fact. Nothing in my interpretation is out of line with the visuals. Certainly some of the heat could have been imparted to the structure. But that is only one possibility. The other, and more likely is that the E-D phasers widen continuously during the firing, and evenly melted (sublimated) the ice around the archive structure.
No. The phaser has been heard stopping firing (double bip, which btw would actually make the firing time between 7 and 8 seconds since initial bip confirmation, if we go by time elapsed on screen), before we get a look at the station with ice melting inwards.
Mike DiCenso wrote:The structure does not "eat" a significant volume of the comet. Given the nearly spherical shape of the comet (it's a comet, not an asteroid, or the energies for melting and vaporization would likely go up by orders of magnitude), plus the fact that the archive's structure is not a solid cylindrical shape and has lots of space wasted, the comet will make up the vast majority of the volume. Let's say a huge 30% of the volume is the D'arsay archive structure. That still means 1.2 gigatons will be required to melt the remaining ice.
Now please check out this:

Image

Don't get dizzy though. It shows that the D'Arsay station only ate a minuscule portion of the comet, and was sitting close to the surface that got bombarded.
This doesn't solve problems, and adds more.

First, it still fails to explain how the last bits of ice to be found were on the station, and why ice shrank towards the station.

Secondly, it shows that the station, being close to the surface, is not close to the core by any margin. Going by the way the beam was projected, it makes even less that the latest bit of ice was on the station.

Thirdly, the visuals show that it requires like 5.5 seconds to melt the equivalent of a dish like ovoid volume of ice surrounding the top of the station (1/4). It demonstrates that even 10-11 seconds is waaaaay below the real duration. Think at least two minutes.
If an initial width of 6m is a correct baseline, then the amount of ice is contained on a flat dish with a radius of a few hundreds of meters at best.

So, even if the end, you get a high energy expense, like several gigatons, you'll also end a wattage that is not in the gigaton/s range.

That said, the scaling I provided will be of use only when someone will make sense of this event, since as far as I'm concerned, the visuals of Masks regarding the ice melting are pure nonsense, and thus puts any estimation based on visuals in severe doubt.










Who watches the Watchers and the 60 GW variance
Again, the dialog, which you either did not see, or chose to ignore, does not support that notion. They are talking about this being a "very critical" margin. It cannot be so wide a margin, or Picard would not be speaking they way he is. This is a very fine edge variance where they need enough power to do the job, but not allow the variance to slip and cause a catastrophe to occur.
Yes and? How does it disagree with my point?
They need power X for their operation. They're not allowed more than a difference of 60 GW in their output, something they don't bother about usually, apparently.

Again, if they needed say 100 GW (likely far far more, but that's just an example in the same ballpark, to keep the unnecessary zeros out), they would have to be sure not to burst over the 160 GW critical limit.
You still don't get it. They are saying things like "as little as", "critical margins", and "variance". To say "as little as", indicates that the overall power output is far greater than you are claiming it to be. If it was as you are trying to interpret it as, Data would have said "as much as".
"As much as" has the same signification than "as little as", safe that "as little as" shows that this variance is a little one.
"As big as", obviously, is a big variance. What that kind of variance would be is up to anyone, but suggesting that it could be vastly more, like 3 orders of magnitude more is already extremely big for me.
Point being, you can't know what the maximum variance can be, and a system that has surges within the megaton range is kinda unreliable in my book.

"As little as" only represents a couple of tons of TNT per second. "As big as" could represent a couple of kilotons of TNT per second. That's generous, it's three orders of magnitude higher.
I don't see the whole fuss like if the variance could reach hundreds of megatons or gigatons.
Really, and it's nothing more than what one thinks how high or low this maximum variance could be. It proves nothing.






Pegasus and Riker's wet dreams
Let's say most of rather means close to 250. Eventually 230 or 240.
What of it? Adding a couples tens of more torpedoes into it won't change things significantly, and on the other end of the spectrum, as you will see, "most of" can also mean as little as 160 torpedoes...
Sorry, but there are simple words to described quantities. 160 is close to half the max load.
Obviously, it would warrant the use of "half of our torpedoes".
But 160 is closer to "two thirds of our torpedoes".
Not to say that for all I can see, people use "most of" to describe an overwhelming majority, near maximum.
Since the torpedoes will obviously have to start at the surface of the asteroid and work their way inward, it will likely require higher total firepower to make up for the losses due to explosion geometries.
10 m wide bits is more than enough, when hurled left and right, to crush a ship located inside. Even more, the torpedoes could be directly fired inside the asteroid. If a ship went there, a swarm will be able to do so as well with large ease. Safe if those torpedoes are inert projetiles once fired.
With the unfocused warhead, a lack of manoeuverability for a missile in the future would be worth a good laugh.
This is addressed below with the size of the cloak that Riker really wants to destroy. As for manuverbility, we've seen torpedoes fly with great precision to a target when required.
So that's not helping your argument at all since they can drive those torpedoes down every hole of that asteroid.
On the other hand, the melt and vaporization energies vastly exceed the above amount, again for an 8.5 km asteroid. Just to cause melting of a granite asteroid would mean expending just shy of 473 gigatons of energy, or 2.65 gigatons per torpedo, assuming 200 of the weapons are expended in the effort.

That's a fairly simple, but reasonably conservative estimate.
It's not conservative in the slightest to require even melting half of the asteroid when simply blasting it to pieces would be plain enough.
Even melting half the asteroid asteroid requires 236 gigatons, or .98 gigatons, if 230 torpedoes are expended in the effort. Conversely, I would still be well in my rights to say that "most of" means "only" 160 torpedoes expended, and I also decide that the asteroid is the full 40 km. So that means that 4,930,000 gigatons is expended in the effort of just melting melting the thing, or 30 teratons per torpedo.

See how that works? As has already been pointed out, "The Pegasus" is a bad example because you can wank it up or down as you like.
As I said, even half of the asteroid being melted is hardly conservative. And as for the "most of" = 160, again, hardly conservative. On the contrary.

Again, context. A group of experts deciding after careful study and deliberation versus an off-the-cuff statement by a desperate man (though he is still an officer and expert) are two entirely different matters. You can see the size of the cloak here at Pressman's feet (the cylinder his hand is on):

http://tng.trekcore.com/gallery/display ... 63&pos=250

It's small enough to survive the ship's being broken up into pieces by some rock chunks. Riker knows that, so it makes little sense he'd want anything less than the total and absolute destruction of not only the asteroid, but the Pegasus.
Because that thing is armored, and is going to survive the explosion of a starship, and the tempest of countless debris from 10 meters to much more propelled left and right, and is going to survive the eventually direct exposition to torpedoes' blasts?

Remember, the ship is in cavity. Even partially buried, just fire the torps in cavities and that's it. The whole asteroid will be fragmented, without melting it uselessly, and the ship will be long destroyed, that little device along.
The Pegasus had been partially buried for over twelve years! If it was going to have blown up, it would have done so a long time ago when the phase cloak failed, and the ship mostly materialized in the solid rock of the asteroid! The ship had no power whatsoever on it's own, it had to have power transfered over to it from the E-D for anything to operate.

On top of that you still keep failing to grasp the context of the situation. Riker wants to make sure that the phase cloak is utterly destroyed. If the ship is destroyed as a whole, but individual parts survive, like the cloak, then it's a pointless exercise to just blast the asteroid to chunks.
Again, how the device is going to survive the destruction of the ship by plenty torpedoes, the eventuall reaction with antimatter and the crush of thousands and thousands of tons of rock?






Pegasus + TDIC = T3h tr00f?
Neither TDiC, nor "The Pegasus", are from alternate universes. One can be made to fit with the other by simple changes in the assumptions. The fact that the Pegasus firepower can be scaled up to within a reasonable order of magnitude of the TDiC firepower is important, whether you like to admit it or not. My preference is for the medium ranges, which also happen to match up with those from most of SG. Once we have an agreement on that, then we can move on. You on the other hand, are the one demanding we except "wankastic" upper range SG firepower, while insisting on us taking only the lower range for ST.
It requires to pump up Pegasus to unfathomable levels, only to meet a completely baseless midly conservative estimation from TDIC while this very episode is an utter mess.

So on the good side for you, it would double any yield calculated for the explosion of a torpedoe on the surface of a hard natural target.

Yes, the ship can be endangered only by a very close range (only few km tops) blasts by multiple torpedoes.

But it neither proves nor disproves any focusing ability. We know from episodes TNG's "Half a Life" that torpedoes can certainly be made to do weird things (as in restart a star). But if the raw energy output of the torpedoes is so great, and if they cannot direct 100% of the energy to the target, then the "leakage" or wasted energy could still be what endangers the ship firing them.

As for it being a "plus", I wouldn't necessarily say that, since you cannot ever have more than half the explosion's energy hit the target. What a torpedo with an uncontrolled blast lets you do is hit a large number of targets with a big proximity blast, and still ensure (if the yeild is big enough) that there will still be a decent amount of damage done regardless.

Possibly, or if you are right; that cannot focus all of the energy, and there will still be enough excess energy released from the combined torpedoes' explosion to cripple the E-D regardless.

Apparently, 50% of a spread of torps at max yield - which was what Picard ordered when able to do so - that close to the ship, would cripple it. It's not illogical. That's actually what you'd expect since torps hitting shields will exactly do that, bare the distance separating the E-D from its target in that case, which was "this close".
Right, but it doesn't preclude anything one way or the other. Just means that there's enough excess energy regardless (if there is some focusing of the explosion) to still endanger the ship firing the torpedoes.

That's my only point here. We can default to saying that for the most part, torpedoes act as an ordinary high-energy explosion, though there are some occasions where their energies can be controlled, however there is still enough inefficencies to allow for a fair amount of the energy to be wasted.


Stargate shields, the non relevance of wattage and power of weapons
Please point to evidence that wattage has a definitive relevance.
Why wouldn't it? Even Atlantis' shields had a definite capactiy, one which could be overloaded after several days of bombardment. This is very similar to Trek shields, which can be overloaded after a specific time. The more wattage, the shorter the time it should take to knock out the shields.
Of course, it will wear down over time, but not the times that are relevant in most spacebattle scenarii.
Above all, wattage is not relevant in the sense that delivering the same energy but faster won't make the attack more efficient, as it won't add extra damage like a bonus.
Of course is relevant. If you pump in enough energy over a specfic time frame, then the shields will collapse and the ship (or city) will be destroyed/severely damage. That suggests wattage can be a factor.

If you have a starship and I have one, and both ships have a shield rating for say... 4,200 TJ. We fight to see who's ship will win. Your weapon delivers 4.2 TJ a second (4.2 TW obviously) as bolts (refire ever .5 seconds), while my ship's weapon delivers 4.2 TJ every 10th of a second, and is a continous beam that can dwell on a target with near 100% accuracy. Who's going to win? Mine will, of course.

Why? Because I can deliver that energy faster as a function of time, and I have no break in my delivery of the energy over your weapon.

Again, the way you explained it earlier, is very similar to an ST disruptor bolt. A quick blob that impacts and disipates over shields or armor. Perhaps you can provide a better discription, or perhaps screencaps to illustrate what you mean?
I guess it's the same story about those disruptors. A blob approaches the shield. The frame later, it's gone, and the shield is fizzling at the point of impact, like it does for anything that hits it.
Even phasers can be fired in a similar manner as per TOS' "Balance of Terror" when they are used in a "proximity blast" mode that fires bolts, instead of a continuous beam.

He's talking about fire... like there's anything on that rock to burn. Where? Last time I've seen an episode about the founders' world, there was only one little tinny winny island sticking out, barren of any vegetation. As for the rest of the surface, I don't know, but if that world was covered at 99.99999% by founder juice, nothing worth of a firecamp could grow underneath.
So it's the wall of ignorance shield again, is it? It isn't just about setting fires, it's about massive fireballs and shockwaves, and what that means for the yeilds. So that is still conservative. As for not setting fires...

http://ds9.trekcore.com/gallery/display ... 77&pos=214

A courtyard where Odo and a the female changling are standing, not the bush next to them (they are actually in a sizeable garden area). The fact that the changelings occupy some portion of their planet as a liquid does not mean they occupy all of it.

He also goes to assume that a certain type of weapon, torpedoes in that case, which for all intents and purposes would have been set to maximum yield in that case, only represented like 10% of the total damage that occured from all weapons being fired in the opening volley, pretty much against the very statement you took (from an episode) about the ratio between phasers and torps.

His assumptions are nothing more than attempts to lower the figure beyond ridicule up to the point where it doesn't fit facts and logic, but somehow would make the event acceptable.
He's doing nothing of the sort. He's simply showing that in the most conservative of calculations just how powerful the event was. On one extreme end you can say that 30% of the planet's crust was destroyed by vaporization (though that doesn't quite fit the visuals), and you get insanely high petatons for ST weapon yeilds. On the other, you get low gigatons. That's the extreme he's showing. He's not in any way trying to make the torpedo yeilds "more acceptable".
The only way to accept this is to assume that by "crust", they meant "surface", which is the (flawed and unsound) premise of his calcs. Of course, saying surface would have been much clearer and technically correct, if that was really what happened.
He is doing no such thing. That is your own misunderstanding of what Graham is doing with the calculations, either intentionally or otherwise.

The point is that he's blatantly ignoring specific informations from the episode (like the flawed and nonsensical computer estimations) to make his nerfed premise valid.
He is not.
I suppose that if destroying the crust is liting fires on the surface, then destroying the mantle is setting fire on its surface... oh wait, how are they going to even reach the mantle as a whole with weapons that only lit fire on the surface?...

So basically, we're again with calcs that are correct but do not fit the elements from the show. They're unacceptable.

You have to be totally honest and play with hands on the table. What info are you ready to neglect from that episode? How far are you ready to go before it fits with former events?
Now you are just being dishonest here. Or maybe you missed this from the article:

So much for the upper case, what about the lower end? Looking at the actual attack itself, it was reported that thirty percent of the crust was destroyed in the opening volley. This time we are after the lowest weapon yields possible, so we will minimise the damage by assuming that 'destroyed' does not mean 'vaporised' as before, and that in fact the attack did not even shatter the crust into pieces. Rather, let's see what numbers we arrive at if we just look at an attack which simply damaged one third of the surface of the planet.


So please. I made no statements about 20 or so gigatons being the upper case, nor is Graham ignoring information from the episode. I know you know about his website, and you've read the articles there. But here's a link to the whole article for you to look at again:

http://www.ditl.org/hedarticle.php?24

I fully stated previously that his goal was to create the lowest possible yeild from the TDiC bombardment.

But the guy who programmed that computer is a total moron. 1 hour to blast the crust, and only 6 hours to destroy the... mantle?
- First, how do you even destroy a mantle? Is it vaporization? They're going to vaporize the mantle over 6 hours? You really believe that?
No, that is a fallacy. There is no indication that the information was false, or that the people running the computer analysis were idiots.
It's not technically possible. How can it be correct? You're going to have a hell of a job to prove the estimation is correct.
You must show unequivacably that the information is incorrect beyond your complaints of "it cannot be so!". We know little about the Founder's homeworld beyond what we see. It probably is geologically "dead", which fits in well with the changelings probably wanting a nice, stable world which they can sit in their natural liquid state as a community forming into a living lake, or ocean.

- Secondly, how can you expect to do whatever to a mantle in 6 hours when your weapons still require 1 hour to destroy the crust? Just check Wong's calculator. Even if it was not totally accurate, check Wong's asteroid calculator. Try a diameter of 23.73 m. You end with 16.8 kilotons necessary to reach the melting temp, for hard nickel-iron, and 100 kilotons to directly reach vaporization.
Lots of conditions can lead to that. The crust of the Founder's homeworld might actually be very thick (as planetary bodies like the Moon and Mars are believed to have), and the mantle relatively thin, ect.[/quote]
These are small bodies. Less pressure. Less heat. It would be an almost dead planet. Not even talking about atmosphere, which seemed pretty breathable. The gravity was Earth like.
Choosing Mars and Moon to only take the interesting bits is cherry picking.

It also means a cooler mantle, thus more energy required to "destroy" it, whatever that's supposed to mean. It does in no way ease your job at making sense out of that.
So? I only gave some real-world examples. I do not understand why you go to such bizarre lengths to try twist this around. Yes, Mars and the Moon are smaller than the Earth. But it is also theorized that at some point the Earth's own internal heat will die enough to where it will no longer have a signficant magnetic field. The Founder's world could be something like that. Old and cooling off. Will the mantle be harder to destroy? Sure. But that does not mean that the crust will be suddenly easier by extension. In fact, a much thicker crust will be far harder to destroy as well, which is what is taken into account.


Plus with a cross section of Mars, the mantle strate would represent 50% of the planet's average radius, with the crust only 1.4%.
I fail to see how taking Mars as an example is going to make the computer estimation even more logical.
Really, you are becoming a bit dishonest here. It was simply a real-life example. I in no way suggested it was an identical situation. For the Moon the crust thickness represents over 4% of the total diameter, and up to 8% of the radius. It is an example that some planetary bodies can have thicker crusts. It is one possibility.

Who said that "destroy" equals "vaporize"? No one one. For all we know they are blasting holes in the crust over time, then blasting off chunks of the mantle with each volley/
Chunks of the mantle?
Plus the yields Graham got wouldn't even approach a minuscule fraction of escape velocity.
This is already answered since Graham was doing his level best in that particular set of calculations to make the torpedoes used in the TDiC bombardment as weak as he possibly could. The higher end calcs vaporize the crust, and a mid-range estimate would certainly be enough to send parts of the crust and mantle to escape velocity.

- Finally, this computer estimation is even more crap, since the opening volley destroyed 30% of the crust, by the same dialogue.
Let me check. Ah, destroyed in a couple of seconds at best, according to events.
Say what?


A conservative planning estimate on their part when you look at the context of them carrying out the operation while the nearest Jem'Hadar bases were some seven hours distant.
Oh, I see. So if 1 hour for crust destruction is measly reduced to something like one or two minutes (a couple of seconds to destroy 30% of the crust, remember), we're left with, what? 12 minutes max to destroy the mantle, if not 6 minutes...

Sure.

Absolutely. Although it has been suggested that the fleet might have needed time to recharge and reload weapons between each volley, so two minutes would be for a continously sustained volley and no need to cease fire, check the results of the bombardment to that point and recharge or reload.

There's also another possibility we've overlooked. In proper parlance, there is no "The Mantle" as such. There is an upper and an inner mantle. The estimate given might not only have been extremely conservative to ensure they could do the job before any Dominion forces could be expected to arrive and stop them, but it may only assume that the crust was being stripped and then one layer (the upper one) of the mantle was being removed.

That would fit with everything.
Mind you, Stargate has a case like that. In Redemption, they believe that a single 1 or 2 gigaton underground blast will destroy all life on Earth.
Totally absurd.
So? How does that equate to TDiC in any real way? None.
It's extremely relevant since this statement in Redemption is as canon as that TDIC. None make sense however.
You still have yet to show that TDiC should not be considered at all. So what about SG's "Redemption"? Having seen the two-parter in question, I don't recall any specifics given about the size of the SG explosion, only that it would continue to build up until it destroyed the Earth. So how did you get a 1-2 gigaton explosion from anyway? Visuals of the Stargate exploding at the end?
There is no evidence that they were wrong, and analysis by Starfleet saw no problems with the plan, either. Until we have hard evidence, there is no reason to assume the Tal-Shiar and Obsidian Order planners were idiots.

I'm pointing out plenty of discrepancies since several posts, and you're brushing them with the back of the hand by stating the characters can't be mistaken, they qualified and veterans, etc.
Forgetting, for a moment, that writers, just like VFX guys, are not omnipotent and not always right.

Until we have information that says the character are wrong, then we cannot dismiss what they are saying. To do so is a serious fallacy of arguement. Yes, the FX people and the writers get things wrong. That is true. But if we dismiss everthing, or nearly everything because of that then we wind up with nothing. If we cannot take dialog, then we take visuals. Visuals for TDiC suggest nothing less than tens of gigatons of firepower according to highly conservative calcs.


Masks, funky ice fusion

It took me a while to find the image you're refering to. The small section of the D'Arsay archive structure is at least 1.5 km tall, assuming that the tractor beam in that image only enlarges out to twice it's size over the distance and therefore the E-D is practically sitting on top of the archive. I think it better to use the phaser beam when scaled to the comet, and not to an unknown quantity like the D'Arsay tractor beam, and the distance from the archive to the E-D.

At any rate, a 3 km wide comet would be actually substantially larger than Graham or anyone else's estimate, and that means that even with only melting occuring, the phasers are still doing a considerable amount of work.

According to Wong's calculator, the melt energies alone, never mind vaporization energies, is still around 1.8 gigatons of energy (163 megatons a second for an 11 second phaser firing).
I'd also consider the volume of the archive itself. As the E-D barely started firing on the comet, the main tower's roof was already sticking out.

I do. Also bear in mind as your own graphic below shows, the archive is not just a solid block, but a series of small blocks with lots of hollow space between them. I don't even want to try and touch that for volume, but to say that the archive does not take up that much of the total volume.

The beam is shown widening. We do not see what happens after the scene cuts away, so to claim that the beam stays at the same state through the whole firing is a bit disengenous. It might, but since the goal was to not harm the core of the comet and spreading the phaser energies out in a wide beam, it is only logical that the beam was widened as the firing went on.
Yes, it is shown widening, but not by that much.
Using the beam's width as a yardstick (6m), assuming it has not immediately widened by the first frame, is how you obtained the size of the comet, right?
The beam when first firing is 11 times smaller than the beam just less than a second before it cuts away (now some 66 meters wide). That's a pretty substantial increase.


My point is that regarding the way energy was imparted, the way the ice melted is completely nonsensical.
But it still is being melted, regarless of what you want to call it. The size of the comet is actually far more substantial than anyone first guessed at.
The phaser did not hit the core immediately, if at all. It clearly starts at the surface, and as the scene cuts away, the archive is just starting to become exposed, but there is still some (glowing) material between the beam and the archive structure. Given that they are not "tunneling", but apparently removing the outer layers of the nucleous' ice to expose the archive, it only stands to reason that they are using the wide beam to cover a large outer layer all around, possibly removing more on one side, but still keeping things fairly even over the course of the operation.
Ok, but that doesn't explain at all the funky physics. Ice, when melting, does not shrinks towards the hotest point.
Otherwise putting an icecube on a warm room would make the icecube dramatically inflate to many times its initial size, and have the water... magically hover in the air.
But that's not what is happening. Or at least I'am not sure what you think is happening as the material is shrinking away from both the archive and the phaser beam as seen better in the second of the three Trekcore.com images:

http://tng.trekcore.com/gallery/display ... 168&pos=69

The phaser is about 5-6 times wide here, but you can also see the target point better as well. The ice at this point is melting away from the phaser beam which is not impacting the archive structure, but is still clearly hitting the outer layers of the comet nucleous and working down from there to expose the top of the archive in the next image. The image after that shows the beam has doubled in side and the ice retreating away from it on either side, and down.

Actually, it's totally surprising and physically impossible. Even more if as you suggest, the structure was heated up a bit to radiate heat, which would be the only solution to still find a source of heat to melt the remaining ice. The point is that no ice should have actually remained on the station. The last bits of ice to melt should have actually been the ones the more distant from the core, from the station.
No. The phaser has been heard stopping firing (double bip, which btw would actually make the firing time between 7 and 8 seconds since initial bip confirmation, if we go by time elapsed on screen), before we get a look at the station with ice melting inwards.
The beeping sound could also just be sounding to let the tactical officer (Worf in this case) know that the phasers will be stopping firing in X number of seconds or what-have-you. If they did stop at 8 seconds duration, that'll only drive the wattage up.


<<image snipped>>
First, it still fails to explain how the last bits of ice to be found were on the station, and why ice shrank towards the station.
Simple, if I understand you correctly. The heat left over in the outer layers of the remaing ice radiated out, sublimating away that ice. Or enough ice was removed that in conjunction with the local star (there is a signficant light source and there was a 'tail' of ionized material trailing the comet nucleous beforehand) and the residual heat from the phasers, sublimated the outer layers toward the station.

Oh yes, I also make out the size of the comet now at 3.1 km wide, assuming a 6 meter phaser beam in the first screencap, and that the curvature follows pretty closely to your sphere image all around. That brings the melt energies up to 2 gigatons. Even if we were to go with your unfounded 2 minute melt time, the phaser is still on 10% power putting out about 16.7 MT a second. At full power, that would be 167 MT a second (10 x 16.7 = 167).

Remember, we are dealing with phasers on only 10% power here. If, as you insist, the phaser timing is only 7-8 seconds (call it 7.5 seconds), then we're looking at 267 MT a second, or 2.67 gigatons a second at full power!
Secondly, it shows that the station, being close to the surface, is not close to the core by any margin. Going by the way the beam was projected, it makes even less that the latest bit of ice was on the station.

Thirdly, the visuals show that it requires like 5.5 seconds to melt the equivalent of a dish like ovoid volume of ice surrounding the top of the station (1/4). It demonstrates that even 10-11 seconds is waaaaay below the real duration. Think at least two minutes.
If an initial width of 6m is a correct baseline, then the amount of ice is contained on a flat dish with a radius of a few hundreds of meters at best.
That's just guessing on your part as we don't see the entire firing sequence, nor if the phaser beam continued to widen out (the loss of ice material isn't uniform, it gets faster and larger as the beam widens). The scene itself also plays out fairly continously, and there is no real indication of a 1.8 minute skip in time. The scaling of the initial beam to the rest of the section shows it to be no less than 750 meters wide (making for a 3.073 km wide comet as a whole). Far more than a "few hundred meters".
So, even if the end, you get a high energy expense, like several gigatons, you'll also end a wattage that is not in the gigaton/s range.
I think you're reaching for straws here. There is no skip in time, and it is easily explained away with the phasers widening around the comet as the operation proceeded.
That said, the scaling I provided will be of use only when someone will make sense of this event, since as far as I'm concerned, the visuals of Masks regarding the ice melting are pure nonsense, and thus puts any estimation based on visuals in severe doubt.

Again, you are reaching desperately for straws here. There is nothing confusing here. The phasers fire, widening over a short time, and perhaps keep widening. The comet appears to be some 3 km wide, and it is nearly completely melted in less than 11 seconds time.

There's nothing funky or confusing, except to those who don't like the implications of a multi-gigaton firepower phaser for Federation starships, and as a consequence, even higher yeild photon torpedoes.


You still don't get it. They are saying things like "as little as", "critical margins", and "variance". To say "as little as", indicates that the overall power output is far greater than you are claiming it to be. If it was as you are trying to interpret it as, Data would have said "as much as".
"As much as" has the same signification than "as little as", safe that "as little as" shows that this variance is a little one.
"As big as", obviously, is a big variance. What that kind of variance would be is up to anyone, but suggesting that it could be vastly more, like 3 orders of magnitude more is already extremely big for me.
Point being, you can't know what the maximum variance can be, and a system that has surges within the megaton range is kinda unreliable in my book.
Except that we have important clues:

* Data chooses to use terawatts, and not simply describe the varience within say, the gigawatt range. If the total output were limited to the gigawatt range as you seem to be suggesting, then he would describe it likely as "must not be off by as much as sixty gigawatts".

* Other evidence, such as photon torpedo yeilds and such indicate at least kiloton to megaton range firepower for weapons.
"As little as" only represents a couple of tons of TNT per second. "As big as" could represent a couple of kilotons of TNT per second. That's generous, it's three orders of magnitude higher.
I don't see the whole fuss like if the variance could reach hundreds of megatons or gigatons.
Really, and it's nothing more than what one thinks how high or low this maximum variance could be. It proves nothing.

No one is stating that the variance is reaching the megaton range. It is however a 60 gigawatt range in an unknown larger amount. The point being that phasers output falls at least within that varience amount, and no less at what is apparently a full power discharge. It is a very narrow margin in a much greater overall amount.

Let's say most of rather means close to 250. Eventually 230 or 240.
What of it? Adding a couples tens of more torpedoes into it won't change things significantly, and on the other end of the spectrum, as you will see, "most of" can also mean as little as 160 torpedoes...
[/quote]
Sorry, but there are simple words to described quantities. 160 is close to half the max load.
Obviously, it would warrant the use of "half of our torpedoes".
But 160 is closer to "two thirds of our torpedoes".
Not to say that for all I can see, people use "most of" to describe an overwhelming majority, near maximum.
Two-thirds or 64% is still a majority of 250 torpedoes, whether you like it or not. Anyway, the point is that you can swing the amount anyway you like down to that relatively small an amount of torpedoes and still keep it in line with what Riker is saying.
This is addressed below with the size of the cloak that Riker really wants to destroy. As for manuverbility, we've seen torpedoes fly with great precision to a target when required.
So that's not helping your argument at all since they can drive those torpedoes down every hole of that asteroid.
They could. But Riker feels that the asteroid needs to be completely destroyed to ensure that the Pegasus and it's illegal cloak be destroyed. It's the context of the thing that you keep trying to hand-wave away here. Maybe later the crew could figure a more efficent way to destroy the Pegasus without resorting to the extremes. But that's not what Riker at that time is suggesting. Even if they send the torpedoes all down the volcanic fissures to create an effect as though they planted inside the asteroid, we still can get gigaton firepower for each torpedo by just playing around with the scalings, and the assumptions. Each torpedo is vaporizing a portion of the asteroid; and the asteroid is at least 12 km wide. Quite simple.
On the other hand, the melt and vaporization energies vastly exceed the above amount, again for an 8.5 km asteroid. Just to cause melting of a granite asteroid would mean expending just shy of 473 gigatons of energy, or 2.65 gigatons per torpedo, assuming 200 of the weapons are expended in the effort.

That's a fairly simple, but reasonably conservative estimate.
It's not conservative in the slightest to require even melting half of the asteroid when simply blasting it to pieces would be plain enough.
Even melting half the asteroid asteroid requires 236 gigatons, or .98 gigatons, if 230 torpedoes are expended in the effort. Conversely, I would still be well in my rights to say that "most of" means "only" 160 torpedoes expended, and I also decide that the asteroid is the full 40 km. So that means that 4,930,000 gigatons is expended in the effort of just melting melting the thing, or 30 teratons per torpedo.

See how that works? As has already been pointed out, "The Pegasus" is a bad example because you can wank it up or down as you like.
As I said, even half of the asteroid being melted is hardly conservative. And as for the "most of" = 160, again, hardly conservative. On the contrary.

Again, context. A group of experts deciding after careful study and deliberation versus an off-the-cuff statement by a desperate man (though he is still an officer and expert) are two entirely different matters. You can see the size of the cloak here at Pressman's feet (the cylinder his hand is on):

http://tng.trekcore.com/gallery/display ... 63&pos=250

It's small enough to survive the ship's being broken up into pieces by some rock chunks. Riker knows that, so it makes little sense he'd want anything less than the total and absolute destruction of not only the asteroid, but the Pegasus.
Because that thing is armored, and is going to survive the explosion of a starship, and the tempest of countless debris from 10 meters to much more propelled left and right, and is going to survive the eventually direct exposition to torpedoes' blasts?
It could very well. Would you take such a chance, if you were in Riker's situation?
Remember, the ship is in cavity. Even partially buried, just fire the torps in cavities and that's it. The whole asteroid will be fragmented, without melting it uselessly, and the ship will be long destroyed, that little device along.
It will? The asteroid debris will be likely blown outward by the explosions. Riker doesn't know at that time that the asteroid will collapse as you describe. That is information Data later mentions when Worf suggests using the phasers to tunnel out of the asteroid to free the E-D.
The Pegasus had been partially buried for over twelve years! If it was going to have blown up, it would have done so a long time ago when the phase cloak failed, and the ship mostly materialized in the solid rock of the asteroid! The ship had no power whatsoever on it's own, it had to have power transfered over to it from the E-D for anything to operate.

On top of that you still keep failing to grasp the context of the situation. Riker wants to make sure that the phase cloak is utterly destroyed. If the ship is destroyed as a whole, but individual parts survive, like the cloak, then it's a pointless exercise to just blast the asteroid to chunks.
Again, how the device is going to survive the destruction of the ship by plenty torpedoes, the eventuall reaction with antimatter and the crush of thousands and thousands of tons of rock?

I've already dealt with this. The device Riker really wants to see destroyed is too small to risk on something like that. He wants to be absolutely sure it is destroyed.

Pegasus + TDIC = T3h tr00f?
Neither TDiC, nor "The Pegasus", are from alternate universes. One can be made to fit with the other by simple changes in the assumptions. The fact that the Pegasus firepower can be scaled up to within a reasonable order of magnitude of the TDiC firepower is important, whether you like to admit it or not. My preference is for the medium ranges, which also happen to match up with those from most of SG. Once we have an agreement on that, then we can move on. You on the other hand, are the one demanding we except "wankastic" upper range SG firepower, while insisting on us taking only the lower range for ST.
It requires to pump up Pegasus to unfathomable levels, only to meet a completely baseless midly conservative estimation from TDIC while this very episode is an utter mess.
As you have been corrected (hopefully) on your mistaken view of Graham's calculations, maybe we can move on from here. There is nothing "unfathomable" about "The Pegasus" calculations. Low gigaton range firepower for torpedoes is perfectly acceptable, unless you happen to not like them because it puts ST firepower on the same footing as SG's.

You're still not getting what he means. What he's saying is that the amount of energy the shields can deflect is not hampered with an increased energy per second figure.

Think of it like this. If the efficency of the shielding is hampered by an increased energy per second figure then you can actually bring down the shields with less energy if you deliver all that energy to the target in a short time-frame rather then a long one.

For example, a shield with a limitation like this can be brought down with a single 6MT missile, but not by two 3MT missiles fired shortly after each other, even though both attacks deliver an equal amount of energy to the shields.
So what about SG's "Redemption"? Having seen the two-parter in question, I don't recall any specifics given about the size of the SG explosion, only that it would continue to build up until it destroyed the Earth. So how did you get a 1-2 gigaton explosion from anyway? Visuals of the Stargate exploding at the end?
I believe dialogue gives the gigaton figure.

Torpedoe focus
Yes, the ship can be endangered only by a very close range (only few km tops) blasts by multiple torpedoes.

But it neither proves nor disproves any focusing ability.
From the very fact that it can be endangered in such a way while destroying or damaging a target with phasers won't ever represent the same level of danger, from teh very fact that there's a backslash from the radiation, we do know that there's no focus at all, if the firing ship can be damaged by a return of energy going backwards. That strictly means an uncontrolled omnidirectionnal blast.
And if it could be controlled, it would have been done, and mentionned, and would have never represented a danger.

Now, maybe they can focus like a percentage of the total output. Bu this would both affect calculations, and the ratio of radiation would have to be presented and supported.
We know from episodes TNG's "Half a Life" that torpedoes can certainly be made to do weird things (as in restart a star).
Nothing to do with focus at all.
But if the raw energy output of the torpedoes is so great, and if they cannot direct 100% of the energy to the target, then the "leakage" or wasted energy could still be what endangers the ship firing them.

As for it being a "plus", I wouldn't necessarily say that, since you cannot ever have more than half the explosion's energy hit the target. What a torpedo with an uncontrolled blast lets you do is hit a large number of targets with a big proximity blast, and still ensure (if the yeild is big enough) that there will still be a decent amount of damage done regardless.
I didn't say it was a plus in that way, only that it would mean that in certain conditions, estimated yields would have to be doubled. For example, if a technician reports a damage of X joules after a torpedoe impact on shields, and if the torpedoe is not focused, then the real yield of the torpedoe was close to X*2.
That's my only point here. We can default to saying that for the most part, torpedoes act as an ordinary high-energy explosion, though there are some occasions where their energies can be controlled, however there is still enough inefficencies to allow for a fair amount of the energy to be wasted.
What are such "controlled energy" (as controlled blast) cases?







Stargate shields, the non relevance of wattage and power of weapons
Of course is relevant. If you pump in enough energy over a specfic time frame, then the shields will collapse and the ship (or city) will be destroyed/severely damage. That suggests wattage can be a factor.
No. That is stating the obvious, but this is not the kind of wattage that is relevant against a specific type of shield. See below.
If you have a starship and I have one, and both ships have a shield rating for say... 4,200 TJ. We fight to see who's ship will win. Your weapon delivers 4.2 TJ a second (4.2 TW obviously) as bolts (refire ever .5 seconds), while my ship's weapon delivers 4.2 TJ every 10th of a second, and is a continous beam that can dwell on a target with near 100% accuracy. Who's going to win? Mine will, of course.

Why? Because I can deliver that energy faster as a function of time, and I have no break in my delivery of the energy over your weapon.
But that's not my point. My point is that stargate shields don't care if you pump 1 MT in ten seconds, or 1 MT in only one second. In the end, it looses 1 MT of shields, and with no difference at all in the effects on the shield. Shields in Stargate don't appear to recharge that much during a battle.
There are, however, shields in other universes where delivering energy faster is of relevance.
For example, what some pro SW-EU people say about how shields deal with energy, where it becomes a matter of saturation.






The Die is Cast: O' Mama!


I beg to disagree.
He's talking about fire... like there's anything on that rock to burn. Where? Last time I've seen an episode about the founders' world, there was only one little tinny winny island sticking out, barren of any vegetation. As for the rest of the surface, I don't know, but if that world was covered at 99.99999% by founder juice, nothing worth of a firecamp could grow underneath.
So it's the wall of ignorance shield again, is it? It isn't just about setting fires, it's about massive fireballs and shockwaves, and what that means for the yeilds. So that is still conservative.
Come on. What you gave me from Graham's calcs (we'll come on that point later btw) clearly showed that the spreading fire accounted a lot for the total damage.

See the second underlined part:



Again taking the planet to be roughly Earth-sized, the damage would cover 170 million square kilometres. To further reduce the yield of our torpedoes I'm going to assume that 90% of this was done by the beam weapons, with only 17 million square kilometres affected by torpedoes. And to cut the numbers down even more I'm going to assume that the damage inflicted was of the most feeble kind. According to the High Energy Weapons Archive quoted above, for any given weapon yield the most widespread effect is thermal - meaning any nuclear bomb will start fires at far greater distances than it will knock down buildings. So for my low end estimate I am going to say that the 17 million square kilometre area was only affected to the extent of having fires started on it.

The fleet launches only ten torpedoes to cause this damage, so each one accounts for 1.7 million square kilometres. This means that each torpedo has lit fires over an area of about 735 kilometres radius. Using the above equations we can get an idea of the yield required to do this damage :

r_thermal = Y0.41
735 = Y0.41
7352.44 = Y
Y = 9,793,653.38

This is in multiples of 2.5 kilotons, so the overall yield would be :

Yield = 9,793,653.38 x 2,500
= 24,484,133,461.48 tons
= 24,484.13 Megatons

Giving each torpedo a yield of 'only' 24 thousand megatons.

As for not setting fires...

A courtyard where Odo and a the female changling are standing, not the bush next to them (they are actually in a sizeable garden area). The fact that the changelings occupy some portion of their planet as a liquid does not mean they occupy all of it.
A place where "people" lived. I have plants and trees in and around my house. However, I put them there. Show me the natural little island and let's see if there's any vegetation that has grown on its own there.
He also goes to assume that a certain type of weapon, torpedoes in that case, which for all intents and purposes would have been set to maximum yield in that case, only represented like 10% of the total damage that occured from all weapons being fired in the opening volley, pretty much against the very statement you took (from an episode) about the ratio between phasers and torps.

His assumptions are nothing more than attempts to lower the figure beyond ridicule up to the point where it doesn't fit facts and logic, but somehow would make the event acceptable.
He's doing nothing of the sort. He's simply showing that in the most conservative of calculations just how powerful the event was. On one extreme end you can say that 30% of the planet's crust was destroyed by vaporization (though that doesn't quite fit the visuals), and you get insanely high petatons for ST weapon yeilds. On the other, you get low gigatons. That's the extreme he's showing. He's not in any way trying to make the torpedo yeilds "more acceptable".
See the first underlined part above.
Wall of ignorance?
The only way to accept this is to assume that by "crust", they meant "surface", which is the (flawed and unsound) premise of his calcs. Of course, saying surface would have been much clearer and technically correct, if that was really what happened.
He is doing no such thing. That is your own misunderstanding of what Graham is doing with the calculations, either intentionally or otherwise.
He's talking about a large part of the damage being wild spread fires. Over an area. You can't make it more surface related than that.
His calcs are not about vaporization of large bits of the crust (in order to reach the mantle later on).
I suppose that if destroying the crust is liting fires on the surface, then destroying the mantle is setting fire on its surface... oh wait, how are they going to even reach the mantle as a whole with weapons that only lit fire on the surface?...

So basically, we're again with calcs that are correct but do not fit the elements from the show. They're unacceptable.

You have to be totally honest and play with hands on the table. What info are you ready to neglect from that episode? How far are you ready to go before it fits with former events?
Now you are just being dishonest here. Or maybe you missed this from the article:

So much for the upper case, what about the lower end? Looking at the actual attack itself, it was reported that thirty percent of the crust was destroyed in the opening volley. This time we are after the lowest weapon yields possible, so we will minimise the damage by assuming that 'destroyed' does not mean 'vaporised' as before, and that in fact the attack did not even shatter the crust into pieces. Rather, let's see what numbers we arrive at if we just look at an attack which simply damaged one third of the surface of the planet.

So please. I made no statements about 20 or so gigatons being the upper case, nor is Graham ignoring information from the episode. I know you know about his website, and you've read the articles there. But here's a link to the whole article for you to look at again:

http://www.ditl.org/hedarticle.php?24

I fully stated previously that his goal was to create the lowest possible yeild from the TDiC bombardment.
As a matter of fact, no, I have not read the articles. There are many of them, plenty, I haven't read them all yet. A very few only, I can't really remember which ones or what they said precisely.
So let's put a term to those accusations you're making since a couple of posts.

I asked you to provide calcs about TDIC, and you did this:

http://www.starfleetjedi.net/forum/view ... =3951#3951
Then there are the torpedo impacts seen in TDiC, which show lower limits in the tens of gigaton range.... well above the phaser yeild for "Masks".
Are there at least detailed calcs to see how people reached that multi GT figure?
Graham worked it out using the Nuclear Weapon's website FAQ formula for calculating yeilds:


Again taking the planet to be roughly Earth-sized, the damage would cover 170 million square kilometres. To further reduce the yield of our torpedoes I'm going to assume that 90% of this was done by the beam weapons, with only 17 million square kilometres affected by torpedoes. And to cut the numbers down even more I'm going to assume that the damage inflicted was of the most feeble kind. According to the High Energy Weapons Archive quoted above, for any given weapon yield the most widespread effect is thermal - meaning any nuclear bomb will start fires at far greater distances than it will knock down buildings. So for my low end estimate I am going to say that the 17 million square kilometre area was only affected to the extent of having fires started on it.

The fleet launches only ten torpedoes to cause this damage, so each one accounts for 1.7 million square kilometres. This means that each torpedo has lit fires over an area of about 735 kilometres radius. Using the above equations we can get an idea of the yield required to do this damage :

r_thermal = Y0.41
735 = Y0.41
7352.44 = Y
Y = 9,793,653.38


This is in multiples of 2.5 kilotons, so the overall yield would be :

Yield = 9,793,653.38 x 2,500
= 24,484,133,461.48 tons
= 24,484.13 Megatons


Giving each torpedo a yield of 'only' 24 thousand megatons.
Nothing else. No link. Just that. So a bit less vitriol and more diplomacy would be nice.
You must show unequivacably that the information is incorrect beyond your complaints of "it cannot be so!". We know little about the Founder's homeworld beyond what we see. It probably is geologically "dead", which fits in well with the changelings probably wanting a nice, stable world which they can sit in their natural liquid state as a community forming into a living lake, or ocean.
Because they couldn't do that on Earth?
It would also be necessary to demonstrate that a geologically dead planet would manage to provide the warm climate found on the Founders' world.
So? I only gave some real-world examples.
Throwing names can be done by anybody. Doesn't mean you've defended your point though.
The examples you gave, I demonstrated that they would still not fit with the computer estimate.
Check Luna's geology estimations.
Again, no way this type of world could match the computer estimation.
I do not understand why you go to such bizarre lengths to try twist this around. Yes, Mars and the Moon are smaller than the Earth.
Here goes gravity.
But it is also theorized that at some point the Earth's own internal heat will die enough to where it will no longer have a signficant magnetic field. The Founder's world could be something like that. Old and cooling off.
And how does it explain the discrepancy? How thick do you believe the crust will become when Earth, for example, will cool down?
Look at the ratio for Mars, again.
Will the mantle be harder to destroy? Sure.
The mantle will always be harder (as longer) to destroy with the volumes we've got, and take much more time than the 6:1 ratio from the computer estimation suggests. Try two digits to one for a start.
But that does not mean that the crust will be suddenly easier by extension. In fact, a much thicker crust will be far harder to destroy as well, which is what is taken into account.
Again, I never claimed that it would be easier. I'm curious as to where you've found this.
Really, you are becoming a bit dishonest here. It was simply a real-life example. I in no way suggested it was an identical situation. For the Moon the crust thickness represents over 4% of the total diameter, and up to 8% of the radius. It is an example that some planetary bodies can have thicker crusts. It is one possibility.
Ah because I have the bad luck shooting down your hope at using an "example" that would magically explain the situation, and so I'm dishonest, again?
What about stopping with your accusations and actually defending your stand with sound theories and solid data, hm?
This is already answered since Graham was doing his level best in that particular set of calculations to make the torpedoes used in the TDiC bombardment as weak as he possibly could. The higher end calcs vaporize the crust, and a mid-range estimate would certainly be enough to send parts of the crust and mantle to escape velocity.
Sure, the high ends talk about god knows how many teratons, the middle ones still talk about so many gigatons, both being yields completely unseen before, and I may even venture to say after, and the low ends get so low, to supposedly be acceptable in regards of the rest of Trek (because that's the exact reason those low ends exist) that they would completely fail at achieving what the computer gave, even less what the report mentionned.

So basically, it's either yields that are non supported by the rest of Trek, and equivalent to the worse ICS wank you can find for Wars, or it's yields that seem to fit in the usual ballpark, but completely dismiss almost the totality of data from this episode and even more.

How a planetoid will still be dense enough to generate the observed gravity and maintain an atmosphere while being small enough so that the crust would be extremely thick, to the point where there may not even be any core as we know it, but just some kind of mantle?

We're simply entering the real realm of the pink unicorn, with an exotic planet of unknown composition and unknown dimensions. We could claim absolutely anything, up to the existence of extremely volatile materials.
At this point, it'd be just as good to claim that this planet is an aggregate of fairy dust.
Oh, I see. So if 1 hour for crust destruction is measly reduced to something like one or two minutes (a couple of seconds to destroy 30% of the crust, remember), we're left with, what? 12 minutes max to destroy the mantle, if not 6 minutes...

Sure.
Absolutely. Although it has been suggested that the fleet might have needed time to recharge and reload weapons between each volley, so two minutes would be for a continously sustained volley and no need to cease fire, check the results of the bombardment to that point and recharge or reload.
Let's take Mars as an example.

Radius: 3,389.95 e3 m
Crust thickness: 5 e3 m

Volume of the crust: V = 7.1145 e12 m³

Let's say that is the volume of an asteroid.
That would give us a diameter of 459,155.46 m, and a vaporization of 3.720 e8 gigatons (for hard granite, less energy hungry than the nickel-iron).
In clearer terms, 372 PT.

To minimize this, say that after the first volley, the fleet has to reload, return to their respective bases, recharge their power banks, and return to this planet.

So we'll concentrate on the 30% of the crust destroyed with a full coordinated assault with 20 ships giving all they have.
That 111.6 petatons. Divided by 20 ships, that's 5.58 petatons of firepower each.

Remember that I consider that all their ordinance and most of their power cores would be dramatically depleted at this point. Of course, numbers would be even greater if I assumed that the fleet had enough firepower to complete the whole task without returning home for refueling and rearming.
Which of course would not fit dialogue since they were supposed to destroy the crust in at least one hour, thus making it impossible for resupply moves.

But still, 5.58 petatons, maybe, at best, one order of magnitude below since the crust is carpet bombed. Delivered in, what? Between one and two minutes (and the very maximum).

And even this high end would sound reasonnable and acceptable? It's not like I considered the crust of a planet like Earth.
There's also another possibility we've overlooked. In proper parlance, there is no "The Mantle" as such. There is an upper and an inner mantle. The estimate given might not only have been extremely conservative to ensure they could do the job before any Dominion forces could be expected to arrive and stop them, but it may only assume that the crust was being stripped and then one layer (the upper one) of the mantle was being removed.

That would fit with everything.
Because you say so? Sorry, it would not, and mantle is a finely accepted term that combines both layers. They say the mantle, then it's both layers.
You still have yet to show that TDiC should not be considered at all. So what about SG's "Redemption"? Having seen the two-parter in question, I don't recall any specifics given about the size of the SG explosion, only that it would continue to build up until it destroyed the Earth. So how did you get a 1-2 gigaton explosion from anyway? Visuals of the Stargate exploding at the end?
It's from dialogue, between Carter and Hammond.
That said, the final explosion in the sky is reported to happen something like 3 million km away, and still lookes like many times the size of the Moon seen at night.
However, I've been theorizing for many years that hyperspace has the ability to amplify explosions, as hyperspace is filled with energy.
This was nothing more than a theory, which I also applied to the destruction of the O'Neill and the three Beliskners as well, in Small Victories I think.
In that episode, the O'neill is sent into hyperspace, lures three Biliskners enhanced by replicators in the same conundrum, and then detonates, destroying all four ships.
This happened after many seconds in hyperspace, which means an insane distance. Yet, the explosion was so powerful that it managed, when returning to normal space, to illuminate the shields of Thor's Biliskner and even push the ship sideway by several tens of meters!

That hyperspace energy theory had no much basis back then, up until the episode in Stargate Atlantis where Zelenka stated that Wraith hyperdrives were somehow strained because of "hyperspace radiations". Possibly a form of radiation that is not harmful per se to most biological beings (otherwhise Sheppard would have been dead in his F-302, and this would be a major concern to most ships in Stargate since they fly shields down), but that would cause massive chain reactions if triggered by explosions in hyperspace.

Well, the final point is that anyway, the explosion seen at the end if incredibly powerful, many many orders of magnitude more than even a gatebuster detonation (that could be the only thing to destroy a connected stargate, and only when placed properly), but in the episode they talk about an explosion of 1 or 2 gigatons at most, that would destroy all life on Earth.

Which is simply impossible, especially with a single underground blast.
Until we have information that says the character are wrong, then we cannot dismiss what they are saying. To do so is a serious fallacy of arguement. Yes, the FX people and the writers get things wrong. That is true. But if we dismiss everthing, or nearly everything because of that then we wind up with nothing. If we cannot take dialog, then we take visuals. Visuals for TDiC suggest nothing less than tens of gigatons of firepower according to highly conservative calcs.
I'm not saying to dismiss everything. Don't exagerate. Only what cannot be made sound, reasonnable and reliable.








Masks, funky ice fusion
I do. Also bear in mind as your own graphic below shows, the archive is not just a solid block, but a series of small blocks with lots of hollow space between them. I don't even want to try and touch that for volume, but to say that the archive does not take up that much of the total volume.
It's still quite bulky and made of thick blocks. It could reduced to the volume of a pear made of legos. Even on this schematic, it still eats a significant volume of the comet.
My point is that regarding the way energy was imparted, the way the ice melted is completely nonsensical.
But it still is being melted, regarless of what you want to call it. The size of the comet is actually far more substantial than anyone first guessed at.
In a way that makes no sense. So until you explain the funky physics at play, the calcs are unreliable.
But that's not what is happening. Or at least I'am not sure what you think is happening as the material is shrinking away from both the archive and the phaser beam as seen better in the second of the three Trekcore.com images:

http://tng.trekcore.com/gallery/display ... 168&pos=69

The phaser is about 5-6 times wide here, but you can also see the target point better as well. The ice at this point is melting away from the phaser beam which is not impacting the archive structure, but is still clearly hitting the outer layers of the comet nucleous and working down from there to expose the top of the archive in the next image. The image after that shows the beam has doubled in side and the ice retreating away from it on either side, and down.
This phase is not the one that interests me. Look at the fusion phase when the station is seen from the main viewscreen on the E-D. This is the phase that makes no sense.

Still, also notice, when the E-D starts to melt ice, how lumps of ice already remain on the apex of the main tower.
Efficient beam, huh. :/
Simple, if I understand you correctly. The heat left over in the outer layers of the remaing ice radiated out, sublimating away that ice.
There's an enormous problem with that.
The E-D didn't circle the asteroid to attack the surface by every angle. It sat there, with the station directly in the LOS of its beam. By the position of the station, it was creating a large dead angle in its shadow, where most of the ice would have formed a sort of cone. Above all, contrary to what the images have shown, the last bits of ice to melt would have not been the ones close to the station, but the ones located far away from it, especially within that dead angle cone.
We see by the position of the E-D, and later on from the view on the bridge's screen, that the station was standing in the way of the beam.
Simple geometry reveals that means a large portion of the ice won't be directly hit by the beam.
Beisdes, it shows that the station will stop a lot of the beam. Thus heat up more than anything else, and as so, completely stripping the sequence of any sense, since the station still has ice on it while the rest of the comet is mysteriously gone.

It's even weirder since the beam was supposed to stop once reaching the core. Not only a large part of the beam would seem to be intercepted, but as a consequence, the final lump of ice to melt due to energy radiation, post beam, would never be located on the station, and would actually look like an hemisphere progressively loosing mass and looking like a flattened lens.

Of course, we should have seen a large part of the ice break off the station.

None of which ever happened.
Or enough ice was removed that in conjunction with the local star (there is a signficant light source and there was a 'tail' of ionized material trailing the comet nucleous beforehand) and the residual heat from the phasers, sublimated the outer layers toward the station.
By looking at the way ice "shrinks" (again, acknowledge that phenomenom will be a necessary phase for you for the interest of the discussion), we see that it's very fast, even after the phasers have stopped firing.
If the sun is responsible of that, you should take that into account for your calcs.
But we see from earlier sequences that the comet does not drastically melt like that, that fast.
Oh yes, I also make out the size of the comet now at 3.1 km wide, assuming a 6 meter phaser beam in the first screencap, and that the curvature follows pretty closely to your sphere image all around. That brings the melt energies up to 2 gigatons. Even if we were to go with your unfounded 2 minute melt time, the phaser is still on 10% power putting out about 16.7 MT a second. At full power, that would be 167 MT a second (10 x 16.7 = 167).
1. You used the asteroid calculator for that. Which by definition will provide numbers which surpass what is necessary to melt ice with a sweeping beam. Try to use the volume and directly calc the amount of energy to melt x m³ of ice. This will be closer to the real amount of energy.
2 gigatons becomes an upper limit that is incorrect because it's based on a repartition of energy that does not match the known facts. It's not a single blast that must have enough energy left, inverse square law in action, to even manage to melt ice at a given radius.
It's a continuous widened beam that progressively melts ice over a more or less large zone.
The larger the beam, the less relevant will be the use of a calculation based on a single omnidirectionnal blast.

2. My timing is not unfounded. It doesn't require a super computer to notice how much ice is actually melted. It's a very small fraction of the overall quantity.
So going by your logic, during the first 5.5 seconds of screentime, the E-D manages to melt a small amount of ice, and in the next 5 seconds or so, quickly melts the rest of the comet, which an amount of is literally shielded by the station itself because mere LOS concerns.
The 10-11 seconds timeframe is unfounded. As I suspected, two camera cuts in the sequence misled observers.

3. You didn't remove the station's volume, which despite your claims, is far from being made of that much spaced blocks. On the contrary, it's made of fused monoliths.
Which will, again, alter the calculations and reduce them.
That's just guessing on your part as we don't see the entire firing sequence, nor if the phaser beam continued to widen out (the loss of ice material isn't uniform, it gets faster and larger as the beam widens). The scene itself also plays out fairly continously, and there is no real indication of a 1.8 minute skip in time.
It only gets faster past a certain point since enough energy has built up. However, widening the beam will hardly make it more powerful.
The scaling of the initial beam to the rest of the section shows it to be no less than 750 meters wide (making for a 3.073 km wide comet as a whole). Far more than a "few hundred meters".
Impossible. With a 6 m wide beam, the part of the station we see is simply to small to be considered even 750 m wide. See, I took a beam 6 m wide at the point of impact, and used the last frame to see the maximum of the exposed station. Even picking the two most distant points on the station, it only gives me a distance of 309 m, and that's an oblique line (37.2°) from end to end.

Plus, didn't they say that the signal precisely came from the core of the comet?
I think you're reaching for straws here. There is no skip in time, and it is easily explained away with the phasers widening around the comet as the operation proceeded.
As I said, widening the beam would not make it more powerful. So, first, you'd be asked to prove that it actually widened to that extent, and secondly, prove that it became that powerful.
Again, you are reaching desperately for straws here. There is nothing confusing here. The phasers fire, widening over a short time, and perhaps keep widening. The comet appears to be some 3 km wide, and it is nearly completely melted in less than 11 seconds time.

There's nothing funky or confusing, except to those who don't like the implications of a multi-gigaton firepower phaser for Federation starships, and as a consequence, even higher yeild photon torpedoes.
We'll see when you'll have, at least, watched the correct sequence.










Who watches the Watchers and the 60 GW variance
"As much as" has the same signification than "as little as", safe that "as little as" shows that this variance is a little one.
"As big as", obviously, is a big variance. What that kind of variance would be is up to anyone, but suggesting that it could be vastly more, like 3 orders of magnitude more is already extremely big for me.
Point being, you can't know what the maximum variance can be, and a system that has surges within the megaton range is kinda unreliable in my book.
Except that we have important clues:

* Data chooses to use terawatts, and not simply describe the varience within say, the gigawatt range. If the total output were limited to the gigawatt range as you seem to be suggesting, then he would describe it likely as "must not be off by as much as sixty gigawatts".

* Other evidence, such as photon torpedo yeilds and such indicate at least kiloton to megaton range firepower for weapons.
Talking about variances by using terawatts demonstrates that variances only evolve within the kiloton range at best.
No one is stating that the variance is reaching the megaton range. It is however a 60 gigawatt range in an unknown larger amount. The point being that phasers output falls at least within that varience amount, and no less at what is apparently a full power discharge. It is a very narrow margin in a much greater overall amount.
Your vastly more powerful is literally meaningless regarding the power of shields in Stargate. A vulgar change in kilotons won't make a big difference, that's the point.






Pegasus and Riker's wet dreams

They could. But Riker feels that the asteroid needs to be completely destroyed to ensure that the Pegasus and it's illegal cloak be destroyed. It's the context of the thing that you keep trying to hand-wave away here.
No. You're desperatedly trying to put those words into my mouth.
I'm merely telling you that your interpretation of "destruction of asteroid" is largely inflated, and above all would be achieved through the bombardment of less efficiency, that is, hit the surface instead of firing most missiles on courses to enter the asteroid by most holes.
Point being, when a house is destroyed, it's not necessarily completely leveled, even less completely turned to 1 cm wide debris, even less completely vaporized.
Maybe later the crew could figure a more efficent way to destroy the Pegasus without resorting to the extremes. But that's not what Riker at that time is suggesting. Even if they send the torpedoes all down the volcanic fissures to create an effect as though they planted inside the asteroid, we still can get gigaton firepower for each torpedo by just playing around with the scalings, and the assumptions. Each torpedo is vaporizing a portion of the asteroid; and the asteroid is at least 12 km wide. Quite simple.
How? A single blast to reach fragmentation energy for 10 wide debris only reaches 1.7 gigatons.
Wouldn't the asteroid be destroyed if turned to such a mass of debris?
That's, again, talking about a single blast, which is not the most effective mean, and thus requires large excess of energy in the core.

Did you even consider the much lower cratering values? Because firing torps hitting the surface of the asteroid will cause exactly that, craters. And sorry, but I think that if your ship sits where there's soon going to be a crater, it's ought to be considered fully destroyed with everything it has inside.

It makes torps confortably sit in the multi megaton range, two or three digits. With 5 of them at full yield, you vastly surpass the power of a phaser.
Remember, a fraction of a second for nukes and any similar explosive, compared to a full second for a phaser's beam.
It will? The asteroid debris will be likely blown outward by the explosions.
Not all of them. There will be bounces, crashes, and parts directly touched by the torpedoes' radiations.
Riker doesn't know at that time that the asteroid will collapse as you describe. That is information Data later mentions when Worf suggests using the phasers to tunnel out of the asteroid to free the E-D.
I didn't use that information for my estimation.
Let's use Wong's calculator, again. For a 12 km wide asteroid, the equivalent craterization would be of a yield of 8.2 gigatons, for a single blast able to create a crater of the size of the asteroid.

Not to say that all those calcs are nice and all, but using 12 km as the diameter is vastly unfair. This is the lenght, not the width. And the asteroid is largely porous.
Good way to pump up the yields!






Pegasus + TDIC = T3h tr00f?
As you have been corrected (hopefully) on your mistaken view of Graham's calculations, maybe we can move on from here. There is nothing "unfathomable" about "The Pegasus" calculations. Low gigaton range firepower for torpedoes is perfectly acceptable, unless you happen to not like them because it puts ST firepower on the same footing as SG's.
-Mike
I stand my position. TDIC is a shame you can't rationalize. Pegasus is often over inflated and used by looking at the wrong numbers, and Masks is, again, inflated and involves a strange phenomenom.

From what episode is this Imhotep's camp example? I would like to check it out myself since the explanation about an “honorable Yu” wanting to reward the Jaffa seems a bit of a stretch. About Kelowna, I don’t know how could they be “holding back”, the System Lords couldn’t care less about Jonas home planet, SG-1 or any pact they might have with Earth at the moment, they only wanted to destroy Anubis super ship before it could become fully operational again, so they endangered their best chance so far by holding back? What, they saw that Anubis shields were only 40% effective on the planet’s atmosphere and they dialed down their weapons accordingly? Instead of doing the exact opposite and take advantage of the situation and get rid of Anubis once and for all? And they wanted to destroy Anubis ship, they actually did it.
Mr. Oragahn wrote:Otherwise, the calcs are particularily rare, and all you have is the base figure of 200 MT and a couple of low gigatons claims at max, for reasonnable low ends. Grenade level explosions are not reasonnable figures, just as much as semi planet-busting claims from an episode.

We're far from the gap of a dozen of orders of magnitude that plagues Star Trek, because one single event seems to suggest a level of power that goes against a vast range of lower yields.
So, there are examples of conventional explosives level, triple-digit megaton level, low gigaton level and teraton level, it doesn’t matter that there is only one example of some of them, they are still there, pretty much like Trek is, with some examples not fitting with the rest. From my POW, both series are inconsistent in that regard, it doesn’t matter if one has less or more examples available, both still are. Arguing about that is pointless.
Mr. Oragahn wrote:I'd rather hear someone rationalize the events and visuals of Masks before expecting people to accept the numbers, and especially tell me where the asteroid was vaporized when Geordi only planed to melt it.
Well, Mike seems to be doing a good job at it. And so far, you are the only one who disagrees with him. Even with only melting, we still got low gigaton firepower.

But unless you can provide some examples of Ha’tak vessels shields withstanding naquadah enhanced weapons on the high gigaton-low teraton level on a naval engagement, then the Sokar example is the only one that supports teraton level shielding, making this the high end for SG, not counting uber races of course. So, that why I said on a previous post that the SG side was leaning too much on the high end for them and arguing too strong for the lowest possible level calculations for the Trek side.

Why? So far your arguments against Mike’s rationalization of the event are failing to convince me of the contrary.

Not a problem, but relaying on memory alone can lead us to make mistakes when stating something, the less ambiguous the best, don’t you think?

I was referring to the team that got there via Stargate, they only brought six and used them as mines, with very little success I might add. I only got a glimpse of the episode where the Deadalus arrives so I can’t comment on what its weapons complement was.

Damn! I have seen too little of SGA! I guess that I’ll have to wait until I got a chance to see those episodes to comment on that too.

Please. Yu was aware about the whole thing since ages. He even let Teal'c return to the planet from where Imhotep was sending his suicide missions. It's Yu who revealed who the jaffa leader was.
If he wanted to destroy him, he could have done so since a while.

Plus, Star Trek First Contact.
About Kelowna, I don’t know how could they be “holding back”, the System Lords couldn’t care less about Jonas home planet, SG-1 or any pact they might have with Earth at the moment, they only wanted to destroy Anubis super ship before it could become fully operational again, so they endangered their best chance so far by holding back? What, they saw that Anubis shields were only 40% effective on the planet’s atmosphere and they dialed down their weapons accordingly? Instead of doing the exact opposite and take advantage of the situation and get rid of Anubis once and for all? And they wanted to destroy Anubis ship, they actually did it.
They had an agreement. Fact. Why Ba'al stuck to it is of no concern to me. Knowing how SG-1 has been a pain in the A for many System Lords, and how many of them died by their hands in fact, somehow I could understand Baal not wanting to throw his own survival into hazard against Tau'ri forces.
Point is, extrapolations or not, there was a deal.
Mr. Oragahn wrote:Otherwise, the calcs are particularily rare, and all you have is the base figure of 200 MT and a couple of low gigatons claims at max, for reasonnable low ends. Grenade level explosions are not reasonnable figures, just as much as semi planet-busting claims from an episode.

We're far from the gap of a dozen of orders of magnitude that plagues Star Trek, because one single event seems to suggest a level of power that goes against a vast range of lower yields.
So, there are examples of conventional explosives level, triple-digit megaton level, low gigaton level and teraton level, it doesn’t matter that there is only one example of some of them, they are still there, pretty much like Trek is, with some examples not fitting with the rest. From my POW, both series are inconsistent in that regard, it doesn’t matter if one has less or more examples available, both still are. Arguing about that is pointless.
Cases in Stargate are actually explainable with data directly delivered in the dialogue or on screen. The lowest yield is the one from the episode The Warrior (with Imhotep) and as demonstrated, Yu could have attacked Imhotep's camp a while ago since he was in the know for a long time.
Besides this episode, the next step is Homecoming, with again, a nice fiting explanation, and after that, we immediately jump to a margin in the 3 digit megaton to low gigatons.
It's not really that hard. No episode in Stargate has ever suggested teraton level firepower for ha'taks, as far as I'm concerned.
Mr. Oragahn wrote:I'd rather hear someone rationalize the events and visuals of Masks before expecting people to accept the numbers, and especially tell me where the asteroid was vaporized when Geordi only planed to melt it.
Well, Mike seems to be doing a good job at it. And so far, you are the only one who disagrees with him. Even with only melting, we still got low gigaton firepower.
Mike doesn't even adress the correct sequence. For the moment, I'm still waiting for an appropriate take on the sequence that creates problems.
As for the low gigaton, again, see above. It's based on a single explosion at the core, which means far energy in excess of what is necessary when you're to melt a ball of cice with a wide beam fired over many seconde (minutes in fact).

He'd rather directly calc the amount of energy needed to melt the volume of ice, instead of relying on a calculator that is about how to blast an asteroid with a single charge placed in the core, which does not even fit the premise of Masks.

How can it be on the high end when even a few bits of raw naqahdah will enhance a 375 KT warhead to a 1 GT one?
Ha'taks are literally filled with weapon grade naqahdah, which by Carter's own admission, was the element which they kept missing to understand the power generations Goa'uld could reach.
Goa'uld have reached control of the atom way before us.
That replacement-for-a-nuke sphere in the picture I posted, based on its weight and how Cameron had issues to carry it, could only be a bomb in the gigaton range, since Goa'uld use weapon grade naqahdah for their weapons, and we know that it's the more efficient and pwoerful variant of the material.

A real high end for Goa'uld weaponry would be what I've seen some people claim to be high two digits gigaton level rounds, calculated from Beachhead. That is a high end, and I can't even picture how they managed to reach those conclusions with the oh so many unknown factors that plague this event.

OK. You really think that the event can be explained within the context of the episode and guess what? You might be right. That’s why I asked for the name of the episode so I can try and see it so I can get a grasp of the situation, because your explanation doesn’t quite convey the idea of them holding back. Maybe after watching the episode it become clear to me as well. But you missed that and stated again that is clear that they were holding back. Well, anyway, you still provided the name of the episode on other part of your post so I’ll try to check it out.

Wasn’t the deal for Ba’al to get there with the combined forces of the Systems Lords and blow Anubis shiny super ship to bits while its main weapon was down and they actually had a chance to do it? That he did, that’s pretty much evident, but again what was his reason to hold back and allow Anubis to escape? Because Anubis was able to escape because his ship wasn’t destroyed right away even with shields at only 40% of effectiveness, if Ba’al allow this to happen by dialing down his weapons then he is a moron and that’s not acceptable. It stands to reason that they were trying their best to destroy Anubis super ship and therefore firing at full strength. And the visuals for the firepower are…inadequate at best. So, what a surprise, SG is inconsistent about the effects of weapons firepower.

I read again your post about firepower and shielding and you’re correct, my mistake. Firepower of 4.32 GT per bolt and shielding of about 1.14 TT. Fair enough.

What are you talking about? I guess you weren’t joking when you said that you had the bad habit of making things more complex than necessary. They wanted to melt the comet, as you corrected, and they did it. Going with your own estimations of some 2-3 km. for the size of the comet that still works at about one gigaton of firepower. That the visuals doesn’t fit your view of how it should look like, well, that’s your problem. Why are you complicating things so much?

All that is nice and I’m not arguing that. The problem with all that is that it doesn’t support teraton level shielding, because AFAIK there is no proof whatsoever of ships being hit with those weapons and survive to tale the tale, nor that those weapons are normally used on naval engagements, so far those weapons are treated and used as one-shot-kill-weapons. That’s why I asked for examples of ships taking hits by these weapons and withstanding them but you missed this or choose to do it, I don’t know, but my point stands, with no evidence on the contrary, the Sokar example is the only one that supports teraton level shielding and therefore the high end for SG. That they can make really big bombs with very little Naquadah doesn’t prove anything by itself, we need their shields to withstand those weapons in order to accept that their shielding is normally on the teraton level and therefore a low end.

It's not might. I am right, because we've seen ha'taks do even more damage on Kelowna. So we know that any claim about Warrior being a great example of superior firepower from the Goa'uld is just plain bollocks.

Borg or whatever, I clearly remember a sequence where bolts land around what looks like temporary launching ramps (the same one used in that episode with Kirk and the temporal thing), and they do only reach some hand grenade/carbomb level of explosion.
I beleive that at one point, most of all more or less SF universes have at least one of such embarassing moments.
Luckily, for Stargate, it's extremely easy to rationalize. For Trek, I dunno.

The deal was to reveal Anubis' weakened position, with Baal agreeing to never endanger the Langarans. Of course, blasting them to ashes would have sure made that deal moot.
The very fact that in Fallout, season 7, Baal sent an operative Goa'uld agent undercover to grab the secrets of the naqahdriah, instead of coming with one or several ships of his tells you that he did enforce, as best as he could, the deal he had made at the beginning of the season.

Actually, the 4.32 GT figure is obtained from the low end shielding figure, 80.64 GT.

Using the middle end figure would provide a firepower of 57 GT.
That would explain why you are against the calculations for Mask and TDIC, with those figures ST would slaughter the SG side and there is not fun in that.
That's not the reason I'm against them. They're figures presented by one side, and when you actually pay attention to the claims and the reasonings behind them, you realize the flaws in them and the generous aspect of the interpretations made from them.

I'm not joking. I'm simply paying meticulous attention to both sequences of ice seen melting, as well as to the amount and way ice is removed.

To sum up, there are two sequences.

First one, we see the E-D fire the beam at the comet. Ice kinda melts (the trick is nothing more than moving the 3D object's vertices down) and reveals a part of the station.
Lumps of ice already remain on that station. From there, we can really see how fast the E-D melts ice. We can see how "much" it melts within 5.5 seconds.

The second and final sequence, seen from tbe bridge of the E-D, shows the whole station, with the last block of ice shrinking inwards, towards the station.
This sequence is the strangest of the two.

Until people check the correct sequences and start to see what's onscreen, instead of seeing what they want to see, I see no point repeating myself on and on.

Which ones? Never have recently made nukes said to be able to toast a ha'tak in one shot, and the sphere I presented was supposed to be ringed down onboard the Ori Crusader. Hardly a regular away to destroy a ship.
That’s why I asked for examples of ships taking hits by these weapons and withstanding them but you missed this or choose to do it, I don’t know, but my point stands, with no evidence on the contrary, the Sokar example is the only one that supports teraton level shielding and therefore the high end for SG.
As I previously said, examples are extremely rare, and it's only recently that we started to get material to chew.
Reckoning shows ha'taks taking several direct hits during a fierce and long battle, even against replicator controlled ha'taks.
Off the Grid has Baal's unshielded ha'tak being attacked by the Lucian Alliance's three ha'taks. Netan (the LA leader) doesn't want to destroy Baal's ship, so he orders his men to aim at the weapons and hyperdrives, while Baal's jaffas work to get the shields back online.
At one point, the shields are back and stop enemy shots.
Meanwhile, the three lucian ships start to shoot at the Odyssey, and the ship has her shields wearing down by elevent percent soon after that.
Then Baal's ship looses her shields once for all, and two shots from lucian ships hit the top of the pyramid, and there goes a chain reaction that destroys the whole ship.

That they can make really big bombs with very little Naquadah doesn’t prove anything by itself, we need their shields to withstand those weapons in order to accept that their shielding is normally on the teraton level and therefore a low end.
Sure, but if their shields can withstand many shots, and since they possess those bombs, yet prefer to shoot the blobs of energy instead, there's a logical explanation to that.
One of them being better firepower.
You can also suggest shield weakening tech for example: less DET, more exotic reaction and after effect on shields.

Here was my take on Stargate's weapons, a part of it derived from old beliefs regarding teh mechanics of Star Wars' weapons:
  • There's much to add to this. Like exotic shield piercing/draining attributes.

    Asuran beams, Ori beams and some Wraith cannons for example seem to do a very good job at draining shields, and their respective powersources, at a very fast rate, while in terms of pure energy, they're not that impressive. Ori beams need several shot to blow up a big temple made of packed dirt, with some fancy ancient gizmos inside. Asuran beams can barely dig through a small asteroid and vaporize small amounts of water. Some Wraith guns may eventually reach 2-digit gigatons yields, while others can literally draw something like many petatons, at the very least, out of a ZPM per second.

    Then you assemble all observations from ha'taks in action, and you come with a theory where ha'tak weapons are defined by several factors:
  • Speed of the projectile. Most bolts are rather slow, but we've seen examples of much faster bolts. I speculate that the faster the bolt, the more it taxes the power core, thus explaining why close ranges are favored.
  • Duration of a single firing. How long you fire the cannon to create a projectile. Most of the cases, the bolts are more less pulses, big balls of whatever energized and poluting matter, sometimes a bit elongated. But sometimes, they can literally be constant rays, with a very low power output, like it happened when Tollana's ion guns were targeted by a ha'tak in orbit. Those low energy rays served as "rails" for the pulse to slide down them and hit their target.
  • Energetic portion of the projectile (ability for Direct Energy Transfer). Basically, pure energy. If the bolt hits solid matter, it will react just like if you poured energy straight into that matter. It will heat up (and get vaporized, then melted, then merely broke part, the farther away you are from the point of impact).
    Then comes the question of how focused the energy is; basically, if the bolt spreads its energy omnidirectionally, or inside a cone. For the sake of logic, advanced weaponry should be focused. Even some nukes now have focused angles, but evidence of this would be prefered.
    That way, with a bolt of X joules of power, nearly 99% of it will be directly delivered into its target. Technically, if it hits the ground, contrary to a nuke that would explode on the ground, the bolt will provide most of its energy to the soil, instead of the surrounding air. In the end, this means we'll see a fireball akin to a nuclear one, of roughly the same size as a fireball created by a nuke of the same yield, even if initially, the ground is super heated and vaporized, and then the rest of the energy is transmitted to the surrounding ground and the atmosphere.
    In the end, the more focused the energy would be, the more similar to a kinetic impact it would look like, instead of an omnidirectionnal detonation.
    However, the final effect will be more of a hot glowing crater, rising lots of soil into the air, even if generates an impressive fireball.
  • Projectile lifespan. Basically, if you intend to create a pulse weapon, you'll likely need to make it able to maintain the destructive energy it contains long enough for it to reach its target. That means creating some kind of skin, or bottle. This, again, would not be gratuitous, and would require more energy. So the shorter the range, the less expensive it would be to create that energy skin. Again, explaining short ranged battles.
    Decaying particles inside the bolt might be responsible of the projectile's lifespan, and define when the skin will collapse to release the bolt's destructive content.
  • Exotic properties (like shield piercing/weakening components). Technically, it's pure technobabble. Often proposed in order to explain the discrepancy between the low DET yields, and yet the rates at which shields drop, and also to explain why such "energy weapons" are important, because of that very special attribute, in comparison to cruse missiles or solid projectiles.
  • Looking on internet for mechanics of lightning balls and other forms of plasmas can be interesting in our case.

    Then you assume that through their computers, gunmen can either choose to put more of this or more of that. Make the bolts slower, faster, pure energy or on the contrary particularily efficient at draining shields without dealing too much damage if the bolt was to hit a structure, etc.

What apparent low number?
Remember, btw, that the latest seasons (9-10) providing more examples of firepower and nukes releases, are also the same seasons where the Ori are conquering more and more worlds, thus cutting Earth's ressources.
But it does not mean that because Earth may not have such an easy access to naqahdah anymore that those ressources don't exist at all.

Masks: a few more points


Looking at Masks for another split moment, and using the schematic I obtained earlier on, we see that it took approximatively 5.5 s (a bit more in fact) to dig a height of ice of 3.11 pixels. By looking at the radius of the asteroid, we see that it takes roughly 41 seconds to reach the core, with such parameters.
However, it doesn't include the fact that the deeper it goes, the more larger ice radius will be, and doesn't even account for a possible further beam widening.

That said, I tried to estimate the amount of ice melted by the E-D.
I went for a conical volume.
I took a point at the edge of the asteroid, closest to the ship, and the point on the bottom of the picture, on the beam's axis, to get a height for the cone. 3.11 pixels.
As for the base's radius, I used the widest possible one, perpendicular to the beam's axis, right to the far edge of the picture. It's actually much larger than the real conical shape of the hole. That's 6.01 pixels.
It ends with a volume that generously exceeds what's been really melted, but at least, we know we get an absolutely acceptable figure.
Above all, it doesn't incorporate the volume already taken by the station.

If 23.20 pixels on screen corresponds to 1550 meters (for a 3.1 km wide ice ball), it gives us a volume of 34.5742 e6 m³ of melted ice, within 5.5 seconds. Which again largely exceeds what really got melted on screen.
Thusly, melting the total amount of ice, at such a rate, would take 5774.54 seconds, or 1.6 hours.

Using the high end figure of 2 gigatons to melt a 3100 meters wide comet in one central blast, it gives a wattage of 346.35 kilotons per second.
1,449.12 terawatts.

That is interesting, considering the variance figures estimated in terawatts.
It would actually demonstrate how a variance of three digit terawatts would be considered high, as one in the gigawatt range would be considered minimal.
That would also explain the relative non harming nature of friendly phaser fire blasts compared to torpedoes, besides the omnidirectional radiation.

Low petawatts of firepower fit well with Who Watches the Watchers, where a fusion plant providing 4.2 GW can power a capital ship's small phaser bank.

Now, the question is to know if Masks is indicating the maximum power they can output.
It's logical that in such a situation, they'd fire the weapon with what is just necessary to melt the ice while taking no chances at damaging the stuff inside the comet.
However, they've been firing enough energy so in the close spot to the point of impact, ice is vaporized and turned into hot flammable material.
It doesn't sound particularily cautious.
Looking at the volume of ice turned to flames, that would correspond to a small volume of the cone I calculated. But since my conical volume generously exceeds the real amount of ice melted, that's not much of a problem.

That said, we can again notice the inconsistency between visuals and dialogue. The station is hardly at the core of the asteroid, contrary to what the dialogues say, so that whole idea about stopping firing when they'd reach the core is weird. Just like a couple of other things I exhaustively listed earlier on.

So fully powered torpedoes are obviously going to be the most destructive weaponry they have, but in limited numbers though.







The war

To return on topic, more globally, it's not easy to say how things will pan out, between Stargate's superior firepower and Star Trek's superior numbers.

There are couple of key elements. The way battles will be orchestrated, the way planets will be defended.

If Star Trek dilutes its whole fleet over many important planets, Gate forces will be able to engage the Trek ships sitting there with fair ease by providing enough ships, regarding each local fleet, and eventually be able to attack the planet without even paying attention to the local Trek fleet, if the target is will identified and if the goal is to simply cause maximum damage.
But this would leave certain Stargate worlds open to counter attacks.

Which brings us to Gate's Earth and Delmak. One has a weapon that will literally rape a vast portion of Trek's total fleet, since thousands of drones are present in the outpost, and since only two of such weapons, fired by a puddle jumper (not relying on a ZPM) can destroy a ha'tak.
If you consider the amount of drones, and think that the guy in the chair would exploit them properly, a few drones would be plain enough for each Trek ship.
In that column fired in Lost City had so many drones... I'm confident that with proper management and a ZPM powering the system, it could engage a fleet of ten thousand ships with no problem.

As for Delmak, between a teraton level impact and moon debris rushing towards the planet, it seems to live fairly well later on. We all know that it's just because the writers didn't think about it that much, just like Lucas didn't think about the DS2 debris heading for Endor. For Stargate, it's even worse, since Netu reappeared one or two seasons later.
A nice blooper. That said, in all logic, no planet could survive that well without a minimal level of passive protection.
Netu exploded in mid season 3, the ha'tak crashed in the beginning of season 5.

The Wraith have the chance to have no world to defend, just their hiveships. Their weakness will be on their necessity to cull worlds inhabited by humans, and eventually, if it's good to their needs, other humanoids.

However, if that was ultimately necessary, they could put many of them back into hibernation.
The firepower and toughness of hiveships is hard to define, but there are clues. This requires its own part.







Wraith forces

At Gateworld, a fellow member of this board and I tried to come with a quick encyclopedia about the wraith hiveships and the Wraith themselves.

You can read it there.

It's awfully segmented due to Gateworld's limit on cars per post.

The essay itself is a bit out of date, as several key elements have to be changed or added.

However, there are bases for gauging firepower, like the bombardment in Misbegotten.

The gigaton estimations could be wrong though. That said, what's undisputable is how a fleet of 10 hiveships and like 20 or 30 cruisers could drain a near full ZPM in a matter of days (less than a week).

The speculation part is on where these weapons come from, and if all ships have them. They've only been used by the first hiveships and cruisers to ever attack Atlantis since the humans put a foot on it. That is, the first three hiveships, then the armada of twelve more.

These weapons, dubbed "falling stars" in the essay, are extremely similar to the dart weapons. That is, low DET (couple of tons of TNT) but able to weaken shields at insane rates, in the petaton range.
Considering their extremely uncanny similarity to dart weapons, it's likely possible that darts themselves couldn't blow large buildings, but could weaken capital ships at a rate worth many universes' best ships.

However, these weapons were only used against a lantian satellite and Atlantis. So we don't know what their effect would be against terran ships, and any other weaponry used against terran ships have been those blue fireballs.

Bar a few weaknesses like exposed unarmoured hyperdrives, hull toughness can be figured out and looks quite impressive.

A hiveship is 11 km long, and can take off planets without much concern regarding structural stress. It can take a close hit from a 304's mark 3 (whatever this is supposed to be), like in No Man's Land, and just get moderately damaged, without being able to spot any significant structural damage. It can fly full throttle near the event horizon of a small black hole, brush against the accretion disk, and survive well enough (though weakened up to the extent of a very close and focused 25 MT nuke will disable it after that, but this can be excused considering that feat achieved beforehand).

There are other elements which feed theories as to how the wraith ships we see now are decomissioned civilian variants of the ships used ten millenia ago.

You can check an essay of mine here (page 4 - pics are missing because stargatecaps is offline, but I should be able to take screenshots myself) to observe the inconsistency between the capabilities of Wraith back then, and what they're only capable of now.

Above all, that essay is pre-Submerged (season 3), that is, before we've seen that what the Wraith used to attack Atlantis were hiveships and cruisers, as far as we're talking about the firstwaves, besides eventual other ships, and that back then, a cruiser, facing all the power of Atlantis' defenses, would only be shot down, not destroyed nor vaporized like it happened lately (even to hiveships), and hit the ocean, sink down there and remain on the seabed for ten millenia without breaking a sweat, on a spot where the underwater crust was particularily thin, like 4 or 6 km at best. So that's a hell of a pressure, yet the cruiser's structure never got compromised, despite the initial damage.

Wraith firepower

As an update to the former essay I linked to, here are estimations obtained differently. It's quite impressive how they actually mesh very well with the former ones.

The current ships, in terms of brute firepower, have the following capabilities:

By using the episode No Man's Land, and noticing that it took between 1:00 and 1:02 minutes to drop the Daedalus' shields by 40%, I had to know what those shields were capable of, and come with a reasonable ROF for the two hiveships.

The first part, I worked from Camelot's evidence. Three ori beams kick a 304's shields down, while a single is almost entirely stopped by a ha'tak's shields, but they still fail in the end, and the Jaffa's ship gets impaled.

If Ori weapons are of any indication in this case, we can assume that a 304 has thrice the shielding of a ha'tak.

So by taking a ha'tak's low end shielding, 80.64 GT, we get 241.92 GT for a 304.
(1.14 T as the medium end for a ha'tak shielding.)

40% corresponds to 96.768 GT.

After looking at all bombardment sequences, timing each bolt occurance, my average rate of fire estimation for that battle came as such: 1.948 bolts / s.
120.776 bolts over 1:02 minutes.

So in Allies/NML, the firepower would have been around this:

809.5 MT per bolt, from the ha'tak's low end shielding, or 9,438.96 MT from the medium end shielding.

However, considering the power of the explosion due to the crash of Cronos' ha'tak (again, a two digit teraton affair), that medium end 1.14 TT shielding seems to be reasonnable, in regards of that episode, Enemies, which the shield strenght was also estimated from.


So assuming that the size of a bolt has anything to do with power, and that seems to be true, given the level of damage produced by the big blobs, we can look at the size of all of them and guess levels.

I observed the ones from No Man's Land.

Based on those measurements (which proved correct as I used them to measure the hiveship, which got me extremely close to the approved 11 km lenght), we see that the Daedalus is like 58 meters high.


A fireball next to the Daedalus' shield in No Man's Land:

Image

This makes the bolt roughly 25 meters wide.


A fireball about to hit the Daedalus in The Hive:

Fire exchanged between two hiveships (although bolts look smaller, they're in fact bigger than the ones hitting the Daedalus minutes ago):

Image

This makes the fireballs being like 100 meters wide.

Looking at the level of damage displayed in The Hive, we know that the yields seen in this episode are superior.

By scaling up firepower according to the volume of the projectile, which is more logical considering the nature of the weapon, and assuming a spherical projectile when standing still, we get a Hive projectile being 64 times more voluminous than an Allies/NML one.
And thus, while firepower in Allies/NML was around 809.5 MT, in The Hive, it would have been about 51.808 GT per bolt for the low end, and a bit more than 604 GT from the medium end ha'tak shielding.











Wraith defenses

Besides the teletransporter jamming technologies, it's all up to armor here. Wraith do not rely on shields. It's understandable, if the only form of shielding they came with would be of no use against shield-bypassing weapons.

There are three incidents where we've seen the wraith firepower used against hiveships. The Hive, Allies (both from the second season) and Misbegotten (third season).
  • In The Hive, two hiveships start to exchange big fireballs that tear huge chunks of armor off their superstructure. Clearly the highest level of firepower ever seen.
    From the first part of that bombardment, the camera is placed above the hiveship on the right. 15 bolts hit it.
    Then comes the second part, immediately in the trail of the first one. The camera is then located beyond the hiveship on the left. The distant hiveship is damaged at several points, and the way the bolts hit it do not correspond to the first part, so we know that it's not just the first part seen from another angle.
    23 more bolts are fired by the hiveship that started to shoot. On these 23 bolts, 21 bolts hit the hiveship before it explodes, but major secondary internal explosions start to occur after the 13th hit, and the whole superstructure starts to glow red from the inside and crack like an egg with the 20th shot, before definitively exploding after a 21th hit which was just overkill.
    So it appears that 20 shots, all hitting the portside's arm will be enough to totally destroy the ship. A destruction enhanced by internal explosions. The arm in question is the elongated part of the structure that is mirrored on the other side, and separated by a multi-kilometer long gap, as you can see here.
    So technically, this part of the ship was saturated with a barrage of two tens of shots. Precisely 21, but 20 of them were enough to cause irreversible damage.

    With the firepower figures obtained above, the total of energy roughly absorbed by this part of the ship before failing is about 1,036.16 GT for a low end, and 12,080 GT for the medium end range.
    There are likely a couple of bolts missing there, considering that the end of the first part does not match the beginning of the second one when it comes to bolt count and position (camera cut for those who don't get what I mean).
    That said, from the first impact to the 20th one, the bombardment lasted at least 10.3 seconds.
  • Allies shows two hiveships, one of which belongs to the minor queen who established an alliance with the Terrans. Both are firing against each other, but hardly doing their best. We learn later on in the episode that both queens were actually working together.
    The size of the projectiles is slightly below the size of the bolts fired at the Daedalus in The Hive, so roughly 50 meters wide. Explosions are not particularily large, and only last two seconds. No bits of hull are seen flying :

    Image
  • Misbegotten shows a damaged hiveship, powered at less than 50%, crewed by Teyla, with McKay's help. Their firing controls are off, so they can't even know what they firing at with enough precision, and can only hope they're pointing the cannons in the right direction, in an attempt to destroy the camp they established down on the planet.
    However, Michael and his half Wraith pals already psychically summoned a hiveship located light years away in hyperspace. An impressive feat, for sure.
    Immediately after this hiveship arrives, it starts shooting at Teyla's ship, but the level of damage is less impressive than in The Hive. That said, the ROF is higher.
    It keeps firing at a high rate for many seconds.
    First, it aims for the prow of Teyla's ship, since it's in direct LOS. We briefly see two starting explosions before camera cuts to the bridge, where we see the heroes getting a bit shaked.
    We stay in the bridge for 19.8 seconds.

    The enemy hiveship keeps moving on, and the second time we see it, it's flanking Teyl'a ship and concentrates its fire on the superstructure's left arm (same spot as in The Hive, but on the other side). This short sequence lasts 3.7 seconds. Towards the end, the hiveship is showing signs of critical damage, as secondary explosions occur in the middle of the ship. Fireballs do not vanish but keep growing, and we get the feeling that the whole vessel is about to go boom.

    Considering that Sheppard and co had time to reach their puddle jumper located in one of the hiveship's bays while running away from the main control bridge, and escape the hiveship at a safe distance, we can only assume it took them some time to do so, though how much is unknown.
    Although the total time from the two sequences is 23.5 seconds, we know it should be more, enough for our heroes to escape. After all, when the camera left the bridge, Sheppard's team wasn't even about to run away.
    A total of one minute bombardment wouldn't be out there, when we can't even know where the huge cavity on that 11 km long hiveship was from the main bridge.
