If a space ship was able to travel faster than our universe is expanding and thus reach the edge, what would happen to the ship?
If you were to jettison yourself out to a galaxy thirteen billion light years away, you would not find yourself in a baby galaxy at the edge of the universe. You would find yourself in a 13 billion year old galaxy in the center of the universe.planetling":1myofccq said:...if we were somehow able to jettison out 13+ billion years toward the beginning of the universe...

We detect Cosmic Background Radiation coming at us from all directions. So, if we consider the CBR that comes from opposite directions, we are detecting radiation emitted from regions of the universe that are now 92 billion light-years apart.

Opps, this doesn't make sense. The part of the universe that is not observable is not observable because there is no light from that distance reaching us. So by definition, no radiation from the non-observable part of the universe could reach earth.
