I'm not reading this whole topic atm but I'd like to point out that the universe is not a sphere as in the 3 dimensional object but is actually a four dimensional surface that wraps back on itself.
Think of how you can fold a two dimensional piece of paper into a three dimensional object, and if you travel along the surface of this object you'll never reach the edge because there IS no edge, and if there is no edge there is nothing beyond. Our universe is equivalent to this, only it is a three dimensional sphere that has been wrapped into a four dimensional manifold, and we're on the three dimensional 'surface' and can't leave it.
