> possible models for the universe is infinite, and dominated by complex universes How can you even know this? Do you have at least ONE model for the universe?

  Sure: there could exist a universe that consists of one elementary particle doing nothing, with no degrees of freedom. There is no law that you could invole that makes this universe any more pobable than our own (except for the observation that our own universe exists, while this one doesn't). There is also the universe described by String Theory in anti-deSitter space - again, possible from a mathematical/logical point of view, maybe simpler than our own universe, impossible to compute the odds for it existing instead of our own. Overall what I'm trying to say is that arguments that 'simpler universes are more likely to exist than complex ones' pre-suppose that there are some laws of physics that apply 'outside' the universe, apart from logic/mathematics. By the way, I'm NOT trying to argue that we shouldn't be looking for a simple set of laws for our own universe - i believe thath is indeed the only option that makes sense, but only from a pragmatic stand-point - it is the only search strategy that guarantees we will arrive at the minimal possible explanation, regardless of how complex or simple that ends up being. Perhaps we'll find a single theory of everything with no physical constants, perhaps we'll end up with 100,000 different fundamental interactions, this part we can't predict.
