this image makes me curious about something:
imagine a distant galaxy, say ~1billion light years away (not 13 like in this new image).
imagine a civilization in this galaxy.
any information takes ~1billion years to travel between us and them.
but say ten years pass from our frame of reference here on Earth.
in those ten years on Earth, did the civilization ~1billion years away also experience roughly ~10years from their point of view?
I guess what I'm trying to ask is, in the time it took me to write this comment, could there be some part of the universe experiencing a much faster rate of time, relative to us? Did a civilization rise and fall somewhere? Does this question even make sense, or is it one of those things where relativity is so unintuitive that asking a question like this is nonsensical?
