I'm confused as to how gigaton or higher firepower would have altered the events in Deja Q and Pegasus?Mith 99 wrote:2) While this is again, evidence that they can wield gigaton firepower, it contradicts other issues like Deja Q, Pegasus, and numerous other episodes where massive gigaton firepower would have easily of solved their problem.
The problem in Deja Q was that the moon needed to be moved away from the planet.
Deja Q
SCIENTIST [on viewscreen]: No, it has a ferrous crystalline structure and it will be able to withstand tidal forces, Captain
RIKER: Could we blow it into pieces?
DATA: The total mass of the moon would remain the same, Commander, and the impact of thousands of fragments would spread destruction over an even wider area.
PICARD: How long before impact?
DATA: Twenty nine hours, sir. Projecting it somewhere on the western continent. That would destroy an area eight hundred kilometres in radius.
SCIENTIST [on viewscreen]: That damage would be insignificant, Captain, compared to the seismic repercussions massive landquakes, and tsunami.
GARIN [on viewscreen]: The force would raise a cloud of dust around the planet, leading to a significant temperature reduction. We could be looking at our own ice age.
How would gigaton or higher firepower have helped? Perfect vaporization is a myth. You would end up with chunks hitting the planet, and the Moon in question was already near its last orbit.
The Pegasus
DATA: This asteroid contains several deep chasms large enough for a starship to enter. It is possible the Pegasus drifted into the asteroid's gravitational field and was pulled down into one of the fissures.

RIKER: Into the asteroid?
PRESSMAN: That's right. Put this fissure on the main viewer. This chasm is large enough for us to manoeuvre in. Besides, if we ever hope to salvage the Pegasus, we're going to need a starship to do it.
PICARD: Mister Data?
DATA: It is theoretically possible, sir, but I am unaware of any prior situations where a starship was taken so deeply inside a planetary body. There may be unforeseen difficulties.
In The Pegasus the asteroid has an impossibly high gravitational field, and they even talk about it as if it was a planet. This is not a mundane object by real world standards.
To make matters worse what Riker says doesn't make sense. There is no way they could have fired majority of torpedos they had on board in the time they had.
How does Rama come to these conclusions? I don't recall ever being told how powerful the solar flares were in Relics, or how quickly they increased in power?Rama Post 281 wrote:That figure is wrong either way, 821.2 gigawatts per square meter is egregiously high.
The thermal energy of a cubic metre of corona gas is less than 0.003 joules, it's incredibly hot, but at the same time it's a diffuse gaseous region in a vacuum. Likewise given that the Dyson sphere possessed 60% of Earth's orbital diameter the emission intensity would have to be on the low end of a typical (otherwise the surface would be a vitrified mess) G class star and that even at the core the fusion power density is less than 300 joules/sec-m^3 (which decreases as the radial distance increases).
Assuming typical stellar luminosity for now an orbit of 10,000km (rather low in the atmosphere) the profile area of the E-D is absorbing roughly 60 MW/m^2, with a profile region of just less than 250,000m^2 (given her rounded shape and odd angles it's far less); totalling at at a maximum radiation absorption rate of 15 TW and 11.6 kilojoules of thermal energy and a roughly comparable transitional kinetic energy (stars are surprising cold given their spectral density). Assuming an appropriate luminosity for the diameter of the sphere, actual emissions absorbed by the E-D would be roughly 6 TW.
According to Data, at 23% the shields would only last three hours, thus indicating that at full strength the maximum absorption rate over 100% of the lifespan of the shields is a grand total of 129 PW (or 31 megatons for the total strength of the shields over twelve hours). Assuming Trek shields aren't based on some retarded percentile principle where the crew continuously allows the shields to drop to zero and kill them rather than dump the waste heat elsewhere, which would realistically put their maximum rate of absorption at less than 6 TW (otherwise the waste radiation gets cycled and dumped harmlessly elsewhere), or more precisely 6 KW/cm^2.
How does this relate to a solar prominence? Well much like the material around it the material within a prominence is incredibly diffuse, assuming a maximum density of ejected stellar matter then the E-D is only absorbing radiation at an intensity of 160 MW/m^2. Even if the E-D is withstanding the brunt of that power for the three hours before their shields become useless, which sounds like a lot in principle, but in reality is only a few megatons of energy dispersed over a long period of time.
Time is in fact the the mitigating factor here.
I also can't see where Rama tried to calculate the energy from the magnetic fields. They were stated to be a threat as much as the radiation.
Why do these calculations seem familiar to me? It's like I've seen them before.
