I think that inflation, I would honestly give it a 50% chance of being part of the final answer. The argument is that think of the two ends of the universe. We have this future which seems to be dominated by this exponential expansion. And you've been working very recently on a new model of the universe on its super-largest scales. That's where we diverge. But so both of us are in the small band of people who've been trying to invent models of the universe...

Sir Roger Penrose has had a remarkable life. He has contributed an enormous amount to our understanding of general relativity, perhaps more than anyone since Einstein himself -- Penrose diagrams, singularity theorems, the Penrose process, cosmic censorship, and the list goes on. He has made important contributions to mathematics, including such fun ideas as the Penrose triangle and aperiodic tilings. He has also made bold conjectures in the notoriously contentious areas of quantum mechanics and the study of consciousness. In his spare time he's managed to become an extremely successful author, writing such books as The Emperor's New Mind and The Road to Reality. With far too much that we could have talked about, we decided to concentrate in this discussion on spacetime, black holes, and cosmology, but we made sure to reserve some time to dig into quantum mechanics and the brain by the end.
