Physicist David Deutsch is author of The Fabric of Reality and the leading proponent of the multiverse intrepretation of quantum theory — the astounding idea that our universe is constantly spawning countless numbers of parallel worlds. In this rare (and delightfully engaging) public appearance, he weaves a complex and captivating argument placing the study of physics at the center of our species’ survival. (Recorded July 2005 in Oxford, UK. Duration: 19:45)
