The multiverse hypothesis, suggesting that our universe is but one of perhaps infinitely many, speaks to the very nature of reality. Physicist Brian Greene, cosmologists Alan Guth and Andrei Linde, and philosopher Nick Bostrom discuss and debate this controversial implication of forefront research and explore its potential for redefining the cosmic order. Moderated by Robert Krulwich and featuring an original musical interlude, inspired by parallel worlds, by DJ Spooky.
