I don't really follow the multi-universe theory as I'm inclined to some sort of determinism. But if every possible outcome of any situation spins off into a parallel universe, how does that fit in with probability? Because it must make any outcome as likely as any other, if every one effectively comes to pass, unless there's something 'outside' the universes, 'rating' them...
Also, doesn't it mean we'll each live for ever, as there's a very small chance each of us, somewhere, will survive any given situation? And, if so, why doesn't our reality contain very, very old people?
