In an issue of Time magazine I Read that we had determined that the Universe will be ever expanding until even one atom will be the size of a Planet. I understand the science behind that. Your Crunch theory has been determined to be wrong already.
I believe that the Universe however vast it is, does have an edge that is ever expanding, and we may never be able to see the edge with our telescopes. (Wow, then again, we may be so far from the original big bang that we could never locate it either. I think I just answered my own question.) And Thanks reverse I liked your analogy.
