Not sure where to post this but I am puzzled by what seems to be a paradox concerning "wraparound" in 3-sphere universe and the expansion of the universe. If we could see to the edge of the universe and saw the opposite side because of "wraparound", would we see a red or a blue shift? Looking at the opposite side from "outside" as it were would mean blue shift, if the universe is expanding. Yet since the non-opposite outermost edge is also expanding, one could argue that it should appear with a red shift. Or would we see both? Could such an observation be used to prove we live in a 3-space?
