I'm not sure if this is the right forum, so move if desired. I read Michio Kaku's Hyperspace a couple years ago, and he breifly spoke of multiply connected spaces. Think of a sheet, bend it in half, and make a cut through eash side, and connect the cuts together to make a "wormhole". Extend this to 3D space etc... From what I know, I've only heard of two different spaces being multiply connected. How would three spaces work? Suppose you want to travel through the wormhole, which one would you exit if there are three connected together? You have two choices. Could you say that you exit both at the same time, kind of like a superposition thing, and you can't know which one until you go through the wormhole and find out? Much like the half dead and alive cat in Schroudinger's cat paradox, or the electron passing through both slits at the same time in the double slit experiment.
