Just something related I thought I would interject:
Using our balloon example we understand that without the two dots actually moving, more space is appearing between them. The result is that they are moving farther apart. In addition the farther apart they are the faster they move apart. Eventually the points can become so far apart that the distance between them is increasing at the speed of light, or even faster! (This is ok because they are not really moving, there is just new space between them. Funky.) Nothing can exceed the speed of light so it is possible that the universe does not wrap like a balloon at all, but rather is like a flat sheet of rubber with the edge being stretched away so quickly that someone standing on the sheet would never be able to catch or even see it.
