Aren't there some things in the universe moving faster away from us than the speed of light so we would never be able to see thm as the light is not comming fast enough for it to ever reach us?
Was there a universe before this one? They say the stars are moving away from eachother and never will come back to together like they once thought. Now, will the entire universe be spread way to thin and everything just die out? Then WHAT!?! THEN WHAT?!!? I think we should start preparing now.
like i said this is cake. Question three is what we should focus our attention to.

i have no idea what it could have been like before then... i know that the guys on mir travelled fast enough to have travelled a full 1/52nd of a second ahead in time (ie, 9 months and 1/52 of a second on earth was only 9 months for the guy on mir). as far as faster than light travel, it might not be possible at all, but a couple theories exit on how it might possibly happen.
If something was moving faster than light, we would see it. point X, 13 billion light years away and moving farther out, would be seen 13 billion years after the fact. point Y (14 billion light years away) would be seen 14 billion years later, even if that was only created 2 seconds after the light at point X. The faster the thing travels the longer and longer between spoting various pulses of light.
as far as expansion, yeah, that's the current theory. Its not something i'm going to have to worry about the ramifications of in my lifetime though, so I'll leave that to the next guy.
