Brian Greene is scheduled to be on CBC Radio 1 in about 30 minutes discussing the mathematical inescapability of parallel universes.
Brian Greene is an American theoretical physicist and one of the best-known string theorists. He has been a professor at Columbia University since 1996. Greene has worked on mirror symmetry, relating two different Calabi-Yau manifolds (concretely, relating the conifold to one of its orbitals.) He has become known to a wider audience through his books for the general public, The Elegant Universe, Icarus at the Edge of Time and The Fabric of the Cosmos, and a related PBS television special.
