$$$SPOILERS$$$ Stargate Atlantis: First Strike/hyperspace

[GStone]

At the end, while Atlantis is traveling in hyperspace, the hyperdrive shuts down (they have yet to say what the reason was and we gotta wait till September for the start of the new season), but the point is that it dropped out of hyperspace when the engine shut down. I remembered when they flew the soon to explode stargate into hyperspace and it exploded far away, but I originally thought it was just the explosion bleeding into normal space, since you can see some of normal space from hyperspace. When Carter bonked her head and figured out that she could turn the hyperspace engines on part of the way, she was partially phased with the cloud thing she and the other ship were stuck in. So, I though that hyperspace was a phased state and the windows themselves were the transition point between being in phase and being out of phase.

Now, I wonder what the windows themselves are for. They are definately the mark in space-time where the vessel has fully come in or gone out of hyperspace. The out of universe answer is it looks cool, but I'm curious of what the in universe answer is. Is it bleedthrough of hyperspace radiation and the hyperdrive alters space-time between the front of the ship and the 'window' itself, causing the excelleration we see? Is the speed up caused by the bleedthrough of hyperspace radiation, which alters space-time, so when the ship travels to the window, we get a visual distortion?

But, if a hyperdrive creates a hyperspace bubble around a ship, so that it is outside the space-time continuum of normal space, we're back to the window issue. When Carter partially took the ship out of phase with normal space-time to escape the space cloud, the ship turned into a semi-transparent, 'ghostly' image of itself. If anything, we should see something like the visual effect of a cloak where it vanishes. But, when they were trying to get all those stranded people off the planet with the massive volcano that was about to explode, McKay says that in his plan to escape, they'll open a hyperspace window, which will allow them to get to freedom.

So, you can see why I'm scratching my head. Does the hyperdrive create a hyperspace 'cylinder around the ship in the direction of the path the ship is to take? I wouldn't want to say that if this one idea is true, that the speeding up is just some throw away idea that's a side effect of the technology or transition between real space and hyperspace.

[GStone]

The window is the point where normal space and hyperspace are divided. That I think is a given. The transition area to and from hyperspace could be where vessels are phasing out of alignment and phasing into alignment with normal space. The speeding up is probably because of the sublight engines pushing you forward, but you are interacting less with the energy and space-time of normal space, so you have less 'resistence'.

(At this point I'm defining space-time itself to be the resultant interaction between 2 or more energy fields, not necessarily the energy fields themselves; they are in space-time when looked at individually, but not when seen as combined energy fields.)

Because there's a partial phase at this point, there is some 'resistence', which is the vessel interacting physically with the ambient energy fields at those areas because the 'hyperspace field' is not at full strength. A real world example of what I mean might be when a space shuttle heads off into space, it encounters less air resistence the further it gets to the edge of the atmosphere and comes up against none after it has left atmo and is in orbit.

Where the window is the spot just before the hyperspace field is at full strength, this allows for some bleedthrough. This bleedthrough happens could be because the hyperspace field might be a two way phasing field and not something specifically one way. Since any ship or city drops out of hyperspace when the engines turn off, it is a forced state, but there's been no dialogue or on screen text that I know of that indicates 2 types of transition fields. One for entering and one for leaving hyperspace.

When hyperspace radiation passes through in to normal space, it dissipates/converts into a form(s) of energy that is harmless to energy in normal space. In fact, hyperspace radiation probably interacts with normal matter in a different way, while it stays within hyperpsace. Hyperspace radiation probably doesn't even exist as hyperspace radiation within normal space. This would explain why we see the escaping hyperspace radiation get sucked back inside the hyperspace window when it closes, whether the window is for entering or exiting hyperspace. The hyperspace radiation that's seen to escape probably returns to hyperspace as it exists the energy field that causes the transition between normal space and hyperspace.

Subspace is said to be beneath normal space and it is subspace fields that are being used by a hyperdrive to transition a vessel to and from hyperspace. It can't be physically lower because physical space is never ending, so its lower figuratively. But, at the same time, it must be an area of space that retains the normal dimensions of normal space or the characters, if nothing else, couldn't act like they do when in normal space. Because McKay says subspace is underneath normal space, it makes me think normal space could be a manifestation of hyperspace.

We have seen at least one hyperspace window that's open within the atmo of a planet and that was the window made by the 302 with the soon to blow stargate on it. So, either its quick transition back to hyperspace or just the concentration of hyperspace radiation, when coming out of an entering or exiting window doesn't harm anything substantially. The reason why the wraith ships have to stop every so often and let their ships heal might be just from the higher concentrations of the radiation they're passing through.

[Mr. Oragahn]

That's a touchy subject.

What we've seen thus far are the following phenomenoms:

1. Ships suddenly accelerating when a less than a second away from going into hypersace. Reverse applies as well when they exit hyperspace.
2. Shipe are not immediately "sucked" inside a window when it's open. An example being the wraith ships which escape in Allies, it takes them more than a second to be sucked in.
3. A ship can graze against an unstable window, almost looking as it goes through, be succintly accelerated over a short distance, be doused in some kind of energy aura for a very short period, but remain in normal space afterwards (Redemption).
4. You can make the window much more stable if you plot a much closer target (Redemption, Fallen). It was said that the shorter the trip, the less energy is needed, and thus you reduce the chances of making a window unstable. The instability of the Naquadriah increases exponentially as you attempt to extract more energy out of it.
   The X-302 couldn't get a lock on its destination once the window was open so it auto-aborted.
   The fact the X-302 veer off-course is due to a safety measure, since we learn that the ship could have actually jumped into hyperspace, but would have ended at an unknown location.
   So the power surges of the naqahdria generator made the hyperspace window unstable and "uncoordinated".
5. You can even make the hyperspace trip very slow; in Fallen, Jack uses the naqahdria based hyperdrive onboard the F-302 to bypass Anubis' ship's shields. The trip lasts a couple of seconds, despite the ship only being a couple of kilometers away.
6. All ships keep their sublight engines on when in hyperspace.
   However, in Prometheus, the Prometheus had its sublight engines offline by the moment it opened an hyperspace window. It's actually that which saved the ship, was her orbit was decaying.
7. Inerta matters in hyperspace, apparently. In Fail Safe and Prometheus, it seems that an object's initial velocity will be of matter while in hyperspace. Otherwise, Carter could have opened a window in any other direction rather than Earth. But she couldn't. The asteroid was moving towards Earth, and apparently, this forbid Carter from veering the asteroid off into another direction, by jumping in hyperspace.
   It doesn't prove that a ship can turn in hyperspace, but it strongly suggsests that a ship has to point in the right direction before making the jump.
8. McKay and Zelenka were arguing about the idea that if a piece or a ship with no hyperdrive, would be severed from a ship flying in hyperspace, Bad Things would happen (No Man's Land).
   We saw that as Sheppard, stuck on the hull of a hiveship flying along another one, in the same hyperspace corridor, hesitated disengaging his F-302.
   Globally, it would seem that if you're inside a ship's hyperspace field, you may leave it en route only if you have a hyperdrive on your own. The results are unknwown, but they sounded worrying. That could be from being dropped to nowhere, to be destroyed or worse, due to funky physics.
9. Several ships present in the same hyperspace corridor (ha'taks, wraith hiveships). Either the hyperspace fields seem to fuse together, or both ship can extend their conundrum, or use the same one if they're sufficiently close to each other.
10. A ship tugging another ship in hyperspace will be slowed down (Unnatural Selection). Thor was tugging the Prometheus around, abck and forth, first from an unknown location back to Earth in the blink of an eye, but would still take "many hours" to reach the Ida galaxy, and Halla, the world where the Replicators were trapped.
11. The size of the hyperspace window is relative to the size of the ensemble that's about to go in. In Fail Safe, Carter proposes to expand the tel'tak's hyperspace field to encompass the 137 km long asteroid.
    Expanding the field requires lots of energy, and as a consequence, reduces the time a ship can stay in hyperspace.
12. Slightly unrelated, but still important regarding energy consumption, Prometheus' hyperdrive generator would produce enormous amounts of energy to open an hyperspace window.
    It was said that if that energy was not channeled towards an hyperspace window (logically, a buffer is charged up), this would generate an explosion with enough force to turn the entire state of Nevada into a smoking crater.
13. In Tangent, Jacob returned to hyperspace after doing hasty reparations, without opening a window. The ship blurred away.
14. Talking about blurring away, this happens everytime a ship goes in or comes out of an hyperspace window.
15. We should leave windows and conundrums colours and shapes aside.
16. In Lost City, hok'jack managed to boost up the hyperdrive of a teltak wile in hyperspace, which enabled the group to return to Earth ahead of schedule.
17. Hyperspace emits radiations which can damage, directly or indirectly, wraith hyperdrives. My opinion is that hyperspace itself is a formidable source of energy, but if it is tapped, it damages hyperdrives.
18. Only massive blackholes can force a ship out of hyperspace, as they increase the power requirements. That said, a ship can finely jump into hyperspace inside the atmosphere of a planet, but the stronger gravity field will tax the engines more.
    Three ships have, thus far, opened a window inside the breathable atmosphere of a planet. Jack's X-302, Fifth's Spider class replicator ship, and the Orion, a lantian damaged warship.
    Only an Asgard ship has shown the ability to enter hyperspace while close to a black hole.
    In Prometheus, an hyperspace window was opened from earth's low-orbit.
19. In Exodus, the energy emission of a supernova boosted the hyperspace trip of Jacob's band, and dropped them far far away from the edge of the Milky Way, in another mass of stars.
    It seems that a window will absorb energy, and this flux does "push" ships.
    Let's notice that Jacob's ha'tak was certainly not caught within the supernova, and the energy surge hit them several seconds after departure. However, once they were hit, they immediately dropped out of hyperspace, in an uncharter part of the universe.
    Apophis' ship, on the other end, was logically going to be hit more directly by the supernova's radiations and blast, as several of his ships were already exploding.
    Yet, mysteriously, both ships ended in the exact same zone.
    Hyperdrives were burnt I think.

Stargate: Hyperspace tugging - range, speed, power.

[GStone]

That's a touchy subject.

What we've seen thus far are the following phenomenoms:

1. Ships suddenly accelerating when a less than a second away from going into hypersace. Reverse applies as well when they exit hyperspace.

2. Shipe are not immediately "sucked" inside a window when it's open. An example being the wraith ships which escape in Allies, it takes them more than a second to be sucked in.

Most of these examples of sublight engine glowing may be an important part in hyperspace transition/travel. I'll talk more about it in the Prometheus example.

3. A ship can graze against an unstable window, almost looking as it goes through, be succintly accelerated over a short distance, be doused in some kind of energy aura for a very short period, but remain in normal space afterwards (Redemption).

The hyperspace field may not have reached the 'transition level' intensity required to make a full arrival into hyperspace. The field might have remained active, allowing some of the hyperspace radiation to still be visible, while the ship was in normal space.

4. You can make the window much more stable if you plot a much closer target (Redemption, Fallen). It was said that the shorter the trip, the less energy is needed, and thus you reduce the chances of making a window unstable. The instability of the Naquadriah increases exponentially as you attempt to extract more energy out of it.
The X-302 couldn't get a lock on its destination once the window was open so it auto-aborted.
The fact the X-302 veer off-course is due to a safety measure, since we learn that the ship could have actually jumped into hyperspace, but would have ended at an unknown location.
So the power surges of the naqahdria generator made the hyperspace window unstable and "uncoordinated".

Since it seems you are out of phase with normal space-time, the only hinderence you'd come across outside of hyperspace radiation is the lost of the field and your shields. Because more stable windows can be created with lesser energy because of shorter distances, travel through hyperspace could use a projection of the field a certain distance ahead of the traveling vessel. With the same amount of energy, a shorter distance/shorter extension of the field can be made more secure because you are not spreading out your energy expenditure over a larger area.

The closing of a window itself could also be an indication of some part of the hyperspace field having left that particular area of space-time, as well as marking the full transition point, as could the opening of one at the end of a trip.

5. You can even make the hyperspace trip very slow; in Fallen, Jack uses the naqahdria based hyperdrive onboard the F-302 to bypass Anubis' ship's shields. The trip lasts a couple of seconds, despite the ship only being a couple of kilometers away.

6. All ships keep their sublight engines on when in hyperspace.
However, in Prometheus, the Prometheus had its sublight engines offline by the moment it opened an hyperspace window. It's actually that which saved the ship, was her orbit was decaying.

Here's where I'm elaborating from above. In most of the instances, sublight engines remain active during travel through hyperspace. Earth created ships don't have their sublight ones on at full burn. They are shown to be much weaker, so this says to me that newtonian engines of some kind are a standard for hyperspace travel. However...since we have seen the Prometheus not use sublights when entering, the hyperspace field itself might supply some movement, but it'd be normal procedure for sublights to be on, given the other examples...probably because the speed and the resultant distance traveled given by the hyperspace field alone is much smaller.

7. Inerta matters in hyperspace, apparently. In Fail Safe and Prometheus, it seems that an object's initial velocity will be of matter while in hyperspace. Otherwise, Carter could have opened a window in any other direction rather than Earth. But she couldn't. The asteroid was moving towards Earth, and apparently, this forbid Carter from veering the asteroid off into another direction, by jumping in hyperspace.
It doesn't prove that a ship can turn in hyperspace, but it strongly suggsests that a ship has to point in the right direction before making the jump.

Weren't they low on power or something? That might have contributed to that situation. Also, was the asteroid attached to the cargo ship or was it just close by? It's been a while since I saw it. If it wasn't attached, then, if they tried to turn, it could have come out of hyperspace on its own and crashed into earth or appeared somewhere inside the earth with its initial velocity and probably would have done some damage. Hell, weren't they inside a 'cave' on that thing and were able to see earth at one point of the asteroid's rotation or were they near the surface?

8. McKay and Zelenka were arguing about the idea that if a piece or a ship with no hyperdrive, would be severed from a ship flying in hyperspace, Bad Things would happen (No Man's Land).
We saw that as Sheppard, stuck on the hull of a hiveship flying along another one, in the same hyperspace corridor, hesitated disengaging his F-302.
Globally, it would seem that if you're inside a ship's hyperspace field, you may leave it en route only if you have a hyperdrive on your own. The results are unknwown, but they sounded worrying. That could be from being dropped to nowhere, to be destroyed or worse, due to funky physics.

Part of the hyperdrive field must act as a buffer to the energies of hyperspace. Since visible light reflects off ships in hyperspace, some of the radiation must be getting through the field, as well as any shields that are up.

But, this brings up another point. Hive ships must stop periodically because they are organic and can't handle hyperspace radiation, like inorganic ships can, like Lantian city ships and warships and Tauri warships. But, even if Sheppard's 302 was inorganic, would it have lasted longer in hyperspace than a hive ship solely because it is inorganic, regardless of the size difference?

9. Several ships present in the same hyperspace corridor (ha'taks, wraith hiveships). Either the hyperspace fields seem to fuse together, or both ship can extend their conundrum, or use the same one if they're sufficiently close to each other.

My initial guess would be that they combined their hyperspace fields to take the strain off their engines to conserve power, if they are close enough.

10. A ship tugging another ship in hyperspace will be slowed down (Unnatural Selection). Thor was tugging the Prometheus around, abck and forth, first from an unknown location back to Earth in the blink of an eye, but would still take "many hours" to reach the Ida galaxy, and Halla, the world where the Replicators were trapped.

Tugging something would probably require expanding the size of the hyperspace field to encompass both things, as well as possibly go back to the normal procedural use of sublight engines during hyperspace trips.

11. The size of the hyperspace window is relative to the size of the ensemble that's about to go in. In Fail Safe, Carter proposes to expand the tel'tak's hyperspace field to encompass the 137 km long asteroid.
Expanding the field requires lots of energy, and as a consequence, reduces the time a ship can stay in hyperspace.

That makes sense, if hyperdrives are designed for levels of strain required for the ship it's being used in. Pushing the limits won't burn out the hyperdrive, but it will make it sooner before it needs rest/repair.

12. Slightly unrelated, but still important regarding energy consumption, Prometheus' hyperdrive generator would produce enormous amounts of energy to open an hyperspace window.
It was said that if that energy was not channeled towards an hyperspace window (logically, a buffer is charged up), this would generate an explosion with enough force to turn the entire state of Nevada into a smoking crater.

Off the top of my head, I don't know what that figure would be, but it'd be huge. But, it would be a start for determining energy consumption of varying sizes of ships. The central body of the Daedalus class and its kin is a little longer than the Prometheus. The height of the tower wouldn't fully cover the width of both 'wings' of a Daedalus. At most, it'd be a little over one. So, we can assume that windows, as well as the fields, for Daedalus classes are gonna be a little more than 303s. I don't remember if it was a 303 or a Daedalus that was show on screen in the size comparisson chart when they were trying to come up with a gas form of the retrovirus to turn wraith into humans, but whichever one they used, it was dwarfed by the hive ship. Their energy consumption per window is through the roof and they have to make more windows with all their pit stops. An Alkesh or even a cargo ship's energy usage would be nothing in comparisson.

13. In Tangent, Jacob returned to hyperspace after doing hasty reparations, without opening a window. The ship blurred away.

It's been a while since I saw it, but could the vanishing have been from activating the cloak before going to hyperspace?

14. Talking about blurring away, this happens everytime a ship goes in or comes out of an hyperspace window.

If its a phase transition, that could happen.

15. We should leave windows and conundrums colours and shapes aside.

Absolutely. There isn't enough info in the canon to talk of that. With Trek, the light around the ship is indicative of just how fast the drive could travel because that particular light wave is being brought along when they first cross c, all visible light, including just white, for the slowest of warp drives. But, we need more info, even indirect stuff, to work on that.

16. In Lost City, hok'jack managed to boost up the hyperdrive of a teltak wile in hyperspace, which enabled the group to return to Earth ahead of schedule.

How did he boost it? Just more power or an alteration of the normal operations of the hyperdrive itself? I know he brought a bunch of stuff with him.

17. Hyperspace emits radiations which can damage, directly or indirectly, wraith hyperdrives. My opinion is that hyperspace itself is a formidable source of energy, but if it is tapped, it damages hyperdrives.

Probably. Both the Asgard and the Ancients didn't use hyperspace radiation to fuel anything. If it was usable, they probably would have. The closest we have are the subspace fields within ZPMs, but they aren't hyperspace.

18. Only massive blackholes can force a ship out of hyperspace, as they increase the power requirements. That said, a ship can finely jump into hyperspace inside the atmosphere of a planet, but the stronger gravity field will tax the engines more.
Three ships have, thus far, opened a window inside the breathable atmosphere of a planet. Jack's X-302, Fifth's Spider class replicator ship, and the Orion, a lantian damaged warship.
Only an Asgard ship has shown the ability to enter hyperspace while close to a black hole.
In Prometheus, an hyperspace window was opened from earth's low-orbit.

Yeah, you can't say the Asgard know what's what with the time-dilation tech in their power cores (First Strike) because Thor was surprised the human form replicators were getting away from the event horizon. He thought they had the time-dilation device, but didn't have any idea how they got it to work, so they could get away from the black hole.

19. In Exodus, the energy emission of a supernova boosted the hyperspace trip of Jacob's band, and dropped them far far away from the edge of the Milky Way, in another mass of stars.
It seems that a window will absorb energy, and this flux does "push" ships.
Let's notice that Jacob's ha'tak was certainly not caught within the supernova, and the energy surge hit them several seconds after departure. However, once they were hit, they immediately dropped out of hyperspace, in an uncharter part of the universe.
Apophis' ship, on the other end, was logically going to be hit more directly by the supernova's radiations and blast, as several of his ships were already exploding.
Yet, mysteriously, both ships ended in the exact same zone.
Hyperdrives were burnt I think.

This is something I've been thinking about. It is odd. As for arriving and getting hit, his ship was bigger than the other one, so maybe it took longer for the hyperspace field to dissipate. Okay, maybe, but the same spot? Maybe his long range sensors detected where the other ship came out of hyperspace and before Apophis' hyperspace field dissipated fully on its own because of getting hit by the shockwave, he had it deliberately disengage, so they got to the same spot?

Why it sped them up...I'm gonna need more time. At the moment, what I'm thinking is that the hyperspace field can be boosted just because more energy is dumped into it and the already existing field somehow is able to use it to boost the distance traveled. Odd, but it's the only thing I can come up with right now without knowing more of its operation.

[Mr. Oragahn]

I was initially going to add points, but let's forget about it.

• In Small Victories, we see the O'neill leave Othala (or was it Halla?). The large screen in Thor's ship shows the new asgard ship flying in an hyperspace tube, only to be caught up by three replicator controlled Biliskner ships. They're all queued, and appear to fly in the same tube, despite the fact that the replicator controlled ships departed later.
  More, the whole point was to self-destruct the O'neill, and thus destroy the Biliskners which would follow it.
  Huh, it seems that after all, hyperspace is not a safe place, and with precise systems, one can catch you.
• In Memeto, Prometheus was dropped out of hyperspace automatically, as the naqahdria generator output too much energy. Fail-safes acted. This happened because the buffer burned, as the ship passed through an intense gravity wave from a collapsing star while, in hyperspace.
  Apparently, the target seemed to be Earth. This would show just how powerful the Biliskner Thor used was, since it tugged the Prometheus from her latest position, back to Earth.
  We'd possibly have to add or cut, either a portion, or the totally of the trip to P3X 744, where the Prometheus ended. It was said to be a 4 month journey using sub-light engines.
  When they reached P3X 744, they directly fed the hyperdrive with the naqahdria reactor, and it went critical, so they had to jettison the reactor module - which was incidentally much smaller than the naqahdah core seen in Prometheus.

Sidenote on the Prometheus hyperspeed capability back then:


GANT
We were supposed to be in hyperspace for another 90 minutes Sir, I don't know what happened Sir.

RONSON
What's our position?

GANT
Four zero point six two lightyears short of the target Sir.

All these phenomena show that energy is generated in advance, according to the distance the hyperspace trip is going to cover.

As for the cloud issue and the half hyperspace phasing:


CARTER
The hyperdrive won't fully engage because of the cloud but maybe it doesn't have to. If I can dial down the power flow to the hyperdrive emitter theoretically I should be able to cause a partial shift into hyperspace, essentially taking the ship out of the cloud's space time. Hopefully just enough to eliminate its effects on the sub light engines.

...

CARTER: It's a long story Sir. Just bear with me. I'm activating a hyperspace bubble to include the alien vessel. I'm going to bring it with us out of the cloud.

Basically what they did in Fail Safe. Minus the full hyperspace bubble and trip.

Weren't they low on power or something? That might have contributed to that situation. Also, was the asteroid attached to the cargo ship or was it just close by? It's been a while since I saw it. If it wasn't attached, then, if they tried to turn, it could have come out of hyperspace on its own and crashed into earth or appeared somewhere inside the earth with its initial velocity and probably would have done some damage. Hell, weren't they inside a 'cave' on that thing and were able to see earth at one point of the asteroid's rotation or were they near the surface?

They were very low on power. The short jump with the asteroid would take everything they had, and possibly destroy the engines.
The teltak itself was located deep down a crevace. How deep is unknown, but they were heading fast inside it, too fast actually, since they didn't knew about the naqahdah enhancing the asteroid's gravity field (impressive, and good to consider for astrophysics in Stargate).
Therefore the ship likely travelled a good distance, so I suppose several hundreds of meters.
O'neill could see his house, or something like that. :)
But that's all. Well, I think. The video might have a shot where Earth could be seen from the cargo. Anyway, the fact that leonides hit the ship and the surrounding area shows they were in a rift, not in a cave. Plus it was very luminous all around.
Nevermind, if inertia had not been a problem at all, considering that there are very chances that cargo ship faced Earth, they could have hyperspaced in any other direciton.
Trouble is that the supermassive asteroid was heading for Earth, and apparently, I supposed, the engines could not be able to counter act the kinetic energy and redirect it elsewhere.
So everybody went through Earth and emerged on the other side.

Part of the hyperdrive field must act as a buffer to the energies of hyperspace. Since visible light reflects off ships in hyperspace, some of the radiation must be getting through the field, as well as any shields that are up.

But, this brings up another point. Hive ships must stop periodically because they are organic and can't handle hyperspace radiation, like inorganic ships can, like Lantian city ships and warships and Tauri warships. But, even if Sheppard's 302 was inorganic, would it have lasted longer in hyperspace than a hive ship solely because it is inorganic, regardless of the size difference?

Seriously, I don't buy it one second. If there are radiations powerful enough to force an armoured 11 km long behemoth to pause because of a sort of strain, there's just no way the glass shield of that F-302 would have protected Sheppard from the same radiations. Besides, crystals are organis as well, and all goa'uld and terran ships use crystals for their advanced systems.

That's why I'm convinced that the Wraith used hyperspace radiations. I think they vampirize a lot of energies they find everywhere. I also believe they suck up the thermal energies of planets to resupply their ships, along possible other power production methods.
If you think about the geothermal energies (theoretical), that would make sense.
Then, they could even fill their buffers up while in hyperspace, and store the energy for other purposes. They'd use hyperspace syphons.

Hyperspace itself seems to be a very powerful thing in itself. In Redemption, the stargate detonated over 3 million miles from Earth, yet the explosion completely whitened the sky, and produced a sorty of glowy thingy that was bigger than what the moon would look like.
Earlier on in SG-1, in Small Victories, the O'neill detonated after flying in hyperspace for a good dozen of seconds.
There are not enough images at stargatecaps.com, but you can still look how far the explosion occured.

The distance was ought to be extremely high, especially since the Asgards would not like to have this detonate too close to their world. Besides, considering that the Replicators were updating the Biliskners beyond the Asgards' comprehension, there's no reason to believe that if the O'neill had superior hyperdrives, they would have to go slower to let the Reps catch them.

Yet, the explosion managed to make Thor's ship's shields flare up, and above all, pushed the massive ship sideways!

This evidence once more the relation between normal space and hyperspace/subspace, and possibly highlights the untapped power of hyperspace.

How did he boost it? Just more power or an alteration of the normal operations of the hyperdrive itself? I know he brought a bunch of stuff with him.

He made modifications to the crystals, zatted them and voila.
Besides that, I don't remember seeing him use a naqahdah generator.
He probably made the hyperdrive better, using his alteran knowledge.

This is something I've been thinking about. It is odd. As for arriving and getting hit, his ship was bigger than the other one, so maybe it took longer for the hyperspace field to dissipate. Okay, maybe, but the same spot? Maybe his long range sensors detected where the other ship came out of hyperspace and before Apophis' hyperspace field dissipated fully on its own because of getting hit by the shockwave, he had it deliberately disengage, so they got to the same spot?

Maybe Apophis wanted to follow them. This is talking about impressive sensor ranges. Apophis could track Jacob's ship and see where he was going. He probably ysed the same route, and both passed through some massive stellar body or something, and got out of hyperspace thereafter.
The lack of such a nearby body isn't important, since even in Memento, when the Prometheus dropped out of hyperspace, it was far from the star which collapsed.

There's obviously a "breaking distance", or something.

Why it sped them up...I'm gonna need more time. At the moment, what I'm thinking is that the hyperspace field can be boosted just because more energy is dumped into it and the already existing field somehow is able to use it to boost the distance traveled. Odd, but it's the only thing I can come up with right now without knowing more of its operation.

Yes, that's basically what we can observe. Now, why this happened... more precisely, how a supernova that didn't even reach Jacob's ship still managed to get swallowed, somehow, and hit the ship with a delay.
Like if a window leaves a "trail", a hole, even after the ship has departed.

Or Apophis' "tube" intercepted Jacob's tube, and transmitted its supernova boost. Of course, there's a delay between the two ships' arrival. Enter that idea you talked about earlier on, about the projection of the hyperspace conudrum ahead of the ship.

That said, as for the hyperspace bubble in Grace, I really don't know what to say. Carter talks about a partial shift into hyperspace, but does not create a half window.

It's been a while since I saw it, but could the vanishing have been from activating the cloak before going to hyperspace?

They didn't activate a cloak as far as I recall.

Maybe Jacob simply returned to a hyperspace route which was already created?

I hate those things you know, because I know this is a visual goof, and I'd rather not pay too much attention to it when we can't even explain the rest correctly.

They were very low on power. The short jump with the asteroid would take everything they had, and possibly destroy the engines.

Then, if they are able to change direction in hyperspace, it would have used up more energy that they didn't have.

Seriously, I don't buy it one second. If there are radiations powerful enough to force an armoured 11 km long behemoth to pause because of a sort of strain, there's just no way the glass shield of that F-302 would have protected Sheppard from the same radiations. Besides, crystals are organis as well, and all goa'uld and terran ships use crystals for their advanced systems.

That's why I'm convinced that the Wraith used hyperspace radiations. I think they vampirize a lot of energies they find everywhere. I also believe they suck up the thermal energies of planets to resupply their ships, along possible other power production methods.
If you think about the geothermal energies (theoretical), that would make sense.
Then, they could even fill their buffers up while in hyperspace, and store the energy for other purposes. They'd use hyperspace syphons.

Then, the stops to heal again may just be that the ships are overeating and a few conduits burst, leading to hull ruptures. It's not the literal meaning McKay seemed to say, but it works.

He made modifications to the crystals, zatted them and voila.
Besides that, I don't remember seeing him use a naqahdah generator.
He probably made the hyperdrive better, using his alteran knowledge.

Okay, so he altered how the hyperdrive was working, which probably altered how the hyperspace field worked, too.

That said, as for the hyperspace bubble in Grace, I really don't know what to say. Carter talks about a partial shift into hyperspace, but does not create a half window.

The window is probably made when the field is set to operate fully. The hyperspace field might be a static thing initially that's projected somewhere in space. It's usually right in front of the ship, but sometimes, it hasn't been. When a ship heads to the window, it gets 'stuck' in the field and the momentum caused by the engines pulls the field with it. The mechanics of the field/tube/bubble at full shift into hyperspace, when combined with the momentum of the sublight engines translates into the distances traveled?

Yeah, I don't like that idea. It might be better to say that they can change course in hyperspace/as they're going into it/while coming out of it.

We need more info. Damn you, writers.

Yes, I hate the things I know, too. ;-) :-P
