He came up with a framework where time is real (assumed), and then the laws of physics evolve with time, and then goes on to develop an evolutionary theory of universes, where universes reproduce by producing black holes, which spawn baby universes, with slightly different laws of physics. He then predicts that it should tend to produce universes that are optimized to produce black holes.
