I was watching a couple of episodes of through the wormhole and it was going on about how black holes can behave like giant particles. also about string theory and how particles are strings that have 11 dimensions. So one can supose that the universe is a string/particle where three of its deminsions became huge. So my question is could it be possible that all quarqs, leptons and messeons are universes that didnt form gigantic dimensions. could they be failed universes?
