Which still applies to my example, since the enterprise never became energy while travelling faster than light when slingshotting around the sun.
That was more of an easter egg, than a factoid in the film...Besides, we already know that lifespans are much longer in the ST universe due to advanced medical science.
Besides, dont even know if it was the same Archer from the Enterprise series.
We dont know why they werent able to evacuate, so there's no point in assuming it would have been as simple as hopping in their ships an leaving.
likewise, Klingon's have pretty advanced technology, so they should have had some idea that their mining would have resulted in catastrophic effect on Praxis, but that didnt prevent it from being blown apart in Star Trek 6.
Yes, its alos loosely and partially based on a real theory called the Penrose Process.
Warp cores also consist of Anti matter. If Antimatter is introduced to a black hole's event horizon it could theoretically have the opposite effect of matter (anti gravity) which would repel an object....However this effect remains unknown in real world science but still makes it a valid candidate for use in a science fiction.
