Personally, I like the idea of some sort of fuzzy subterranean gremlins from Mars.

Elon arrives and they prank him to death.

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.

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?

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.
