@Anphase the universe is expanding at a rate where light can not catch up to the outer border of the universe at its place where the last light source would be. but at the same time the universe expansion theory suggests that light sources like our sun are following this ever expanding border and eventually finding their place and staying their.
-
This may be a dumb question: is the universe expanding faster than the speed of light?
-
I have a question though. If the distances increases while the light is reaching from lets say a star, how do we know the star acutally exist right now? Maybe if we are up in space with a super fast space ship and wants to fly to a star, while flying towards it it slowly faints away, and when we get there it's gone. It wa sjust the light that was still there!

@lolwut162 he explained that this whole time bro

Oh, well than there's your answer. :D

If the universe is 14 billion years old how can something be 46 billion light years away from us?
-
@stuner760 Yeah I thought so too. Haha yeah I thought of that as well. But the reason I asked is because he says that there exists part of the universe that is outside of our 13.7 billion year light bubble. So I assumed from that that the expansion is faster.

@yamenhawit I thought they were the same?
but think of this...if the speed of light were faster..what would happen to the light?:o

When you start feeling extremely confused about this, it's because you're starting to understand. Keep thinking!
