There is much more to this than the ladder paradox and I think it is a very good question.

One aspect that has not been touched on is the visible horizon of the universe. Even if the universe is finite, but much larger than the visible horizon, it seems very unlikely that an observer moving at very close to the speed of light relative to the CMB will see beyond the visible horizon. Any thoughts on this?
