some dude on a TFC server told me that originally the universe started with 12 dimensions, but that only 3 significantly expanded, and that is why quantum mechanics often deals with things on the small level because these dimensions didn't expand with the rest of the universe. I'm talking about phenomena such as electron tunneling (where an electron appears on both sides of a barrier in a transistor).
Does this ring a bell to anyone? I haven't found it stated in exactly this same way (I'm reading http://plato.stanford.edu/entries/qm/#4 right now)
Hmm.
