GREAT point! I was actually going to bring this up.

When talking about the laws of physics, it actually depends on which Multiverse model you are talking about. In something like the Many Worlds Interpretation of quantum physics, each universe that branches off, MUST obey the same laws of physics (ours) So, no....you couldn't really have the world of, say, Harry Potter or Nightmare On Elm Street.

HOWEVER, if you are talking about Eternal Chaotic Inflation Theory, each bubble universe that sits in De Sitter Space could have an infinite variety of physical laws. Each bubble universe would have it's own laws of physics. I don't want to get into the math, but basically the laws of physics we know are governed by only a very small set of constants. In Eternal Chaotic Inflation Theory, each bubble universe would HAVE to have totally different physical constants, due to each "bubble" being totally independent from the other. In this scenario, there wouldn't be a limit to what could arise, and every single thing one could conceive (and even the things we can't conceive of) must be realized, and realized an infinite amount of times.

I know this sounds like science fiction, but these are real theories put forth by cosmologists. Which multiverse model is right? Are ANY of them right? Could more than one be right? These are very difficult questions, but believe it or not, are relatively close to being proven or disproven either way. The next generation of particle accelerators, the rise of quantum computers, etc will prob. answer some of these questions in our lifetime.
