Love it!

My highschool hypothesis was that black holes and the big bang are effectively one giant interconnected probability function, with black holes collecting all matter in the universe and concentrating it in a single singularity which enables the big bang to occur. So you have a single self-sustaining cycle, which is really no more than an incomprehensibly large example of Schrödinger's cat. In a way.

I'm sure that was all triggered by subconscious angst arising from reading about the slim probabilities that allow for the universe to exist, string theory, worm holes, and all that jazz.

That said, I like to think that it tidily manages the n-dimensionality, circularity of time, etc. problems.
