Energy beings are the only aliens that could possibly live long enough to make interstellar travel a possibility. Either Robots or some kind of extradimensional being.
If black holes turn out to b a gravitational condensate with no event horizon, you could have FTL and a hyperbolic space time at the same time, since the condensate would have negative energy pressure.
I’ve actually been wondering what the simplest experimental proof of relativity would be though. I know GPS is one practical application that has to account for the way gravity bends time which is based on light having a constant speed, but that’s hard to demonstrate.

Some close encounter stories talk about robots and there’s a theory that grey aliens are androids, or something.
Natural hibernators with a medusae like tellemere protection factor could work.
You still believe in the speed of light?
