we'd be God or the physicist on the other side, or in my case, it's just chance collisions of menbranes that are responsible, i.e., nature.

I think it's safe to say that physics and thermodynamics as we know it might have to be changed somewhat to allow this to happen. M-Theory proposes an 11-dimensional space, so whose to say what mass and energy are doing in the other dimensions? M-Theory (Membrane Theory) allows a physics that transcends the singularity of the big bang, which has been a troublesome issue for cosmologists for a long time.
Haven't heard much about chaotic inflation theory.
