There's no chaos in quantum mechanics if what you're doing is following the evolution of the wave function of the universe. Everything is linear and it's actually pretty simple, but we're not following that right now. We're following the development of branches of the wavefunction - which are little tiny particular slices of the Wave Function. There was a question about whether there were black holes at the centers of some small galaxies. Jeffrey Seagal: Yes, there is a correlation between central black hole size and the size of the galaxy. It's unclear to me how this works.
