- Can we view the history of space from the edge of expansion as it was expanding faster than the speed of light?
I was wondering if it would be possible to see the history of space if one was to stand at the edge of the universe as it expanded faster than the speed of light. If the universe was to be expanding faster than the speed of light right now, and I was able to somehow go there and keep up with it, what would I see if I turned around? I have thought about this and I was wondering if you would be able to see the history of the universe. Since the universe would be moving faster than the speed of light, all the light traveling to the edge of the universe would lag behind it and thus if you turned around and stopped, eventually all of that light would reach you. So what exactly would you see? Would you just see light from galaxies, etc., or would you be able to see the the formation of the universe?
This also leads me into a side question. Since the universe is not expanding at the speed of light, what happens to the light that reaches the edge of space? Does it just move at the speed of the universe expansion? If that is the case, this is why I reached the conclusion above (that you can see the formation of the universe). If the Big Bang is true then as the universe started expanding, that light being emitted is just following the edge and so you would see it if you were at the edge.
Have I made a mistake in my thinking or is this certainly true?
