I have this sneaking suspicion one of the new dimentions of string theory is where at every planck level there's a link to our largest level universe. Maybe we're in a mobius shape where two trips through would be needed to complete the journey. This multi-faceted torus idea best soothes my finite-infinite question - it's both. Okay, I've let the cat out of the bag; when do I pickup my Nobel Prize? LOL ;-)
