Einstein's general relativity says gravity is spacetime curvature, but what does that mean? Let's take a look at how gravitational time dilation results in a...
What’s really freaky is one of the theories we can’t see other life, is to our perspective (due to expansion of the universe) their rate of expansion is faster than the speed of light, and we won’t know till they’re pretty much at our doorstep.
There might be a bunch of them all over, jumping around the universe and claiming everything they see like old school European countries.
If that happens the best result is they make us a “colony” but honestly a civilization that scale doesn’t need resources or anything. The most likely explanation for that behavior would be just to eliminate any future competition if we advance unchecked.
Rather than colonize, they might just want to wipe out our planet, which would be practically effortless for a civilization that advanced. If something crashed into Earth at those speeds, the planet itself would be gone, no way for us to survive or even stop it.
The only defense is to spread out from Earth, which makes the hypothetical advanced space race afraid of our expansion kind of right
Any civilization in a universe like that needs to constantly expand just to ensure it’s survival. Because the only reason we’d be preserved was if they cared about the novelty of life.
If they’ve spent millions of years expanding their space, alien life probably isn’t that novel to them anymore. So really, our only bet is we’re entertaining, like a zoo.

Why do you assume they’re hostile?
Maybe they want to help but respect our free will as a species.
