Actually, for anyone who's interested, there was a documentary on H2 not long ago about Cosmological Natural Selection. Which is like... new universes are constantly being born with the birth of black holes. Its kinda hard to explain, but with each new black hole, a new universe is born. The laws differ slightly, and with each difference a completely different universe is formed. According to this theory, the number of black holes a new universe creates is directly related to how... well a universe has evolved. The more black holes, the better. And the 'multiverse' will take these well evolved universes into account and create more universes like those that were successful in their evolution, or something.
(If you want more information you could just google it, haha. I don't remember everything on the subject but it was really interesting)
There was also a thing on how the universe could be a living being ('living' being defined as a 'thing' that has a system that works and sustains itself--a city would be considered 'living'), and stuff like that but it was a while ago and I'm can't remember all the details. lol
