This action-packed talk explores the possibility that our universe is part of a vast complex of universes called the multiverse. The animated lecture is given by theoretical physicist Brian Greene, perhaps the best-known proponent of superstring theory, the idea that tiny strands of energy vibrating in a higher dimensional space-time create every single particle and force in the universe.
