Think about it though. Most of our theories of how things work are all based on closed and isolated systems. Everything we've seen of the Universe so far doesn't necessarily lend itself to being a "closed" system. Physicists knot themselves up coming up with extra-dimensions to make some of the observational data match their equations.
What does a black hole do? It sucks in matter and energy and strips it down to a level where even quarks act funny. As a blackhole radiates (one of the few things I think Hawking really got right), this energy is leached back into space-time via virtual particle pairs. Background radiation anyone? The blackhole phenomena becomes an anti-entropy device in essence. No "luke warm soup", no "big crunch", no BS...
Very neat. Very tidy. Dr. Occam can give a heck of a haircut.
I realize it isn't your theory, please consider it a generic "you". Sorry about that...
