Right, I had this theory as a teenager, reading popular physics. I'm sure lots of other people noticed the big bang / black hole symmetry. A pretty model should not be enough to make it significant... otoh, relativity theory was once just a pretty model too. Is their model pretty enough? Also, any matter falling into a black hole should appear in the other universe. It would be an interesting to have new mass/energy appearing in our universe.
