Ah, but as there are an infinite number of universes, it follows that there an infinite number of universes where the "alternate you" crosses into another universe, but in each one he crosses into a different universe. So at least one of the infinite number of "you"s should have made it into this universe...
Which suggests the theory that is not possible to move between the universes.
