How would they interact? As for the universe wrapping around on itself, that simply means the universe is finite and non-bounded.

What about folds in space/time that would allow continuity and yet altered laws of physics? If the universe folds upon itself, several constants of the universe would cease to be constant at long distances. This hypothesis (I first saw in a sci magazine) would solve many of the odd problems that seem to defy explanation.
