I had a thought while reading about some novas observed at 11 billion light years from earth. Current thought is that light from these distant objects occurred billion of years ago because of their red shift. But if the expansion of the universe began linearly after the Big Bang (moving away in a straight line), but space-time is warped by the original gravity of the expanding universe then space-time might be wrapped around the original singularity. Therefore, what we are seeing might not have actually occurred so long ago but is the result of the expansion (wrapping of) space-time. This would also explain the observed acceleration of the expansion of the universe.
