Infinite worlds: a journey through parallel universes
Infinite worlds: a journey through parallel universes
The multiverse hypothesis, suggesting that our universe is just one of perhaps an infinite number, speaks to the very nature of reality. Join physicist Brian Greene, cosmologists Alan Guth and Andrei Linde, and philosopher Nick Bostrom as they discuss and debate this controversial implication of cutting-edge research and explore its potential for redefining the cosmic order. Hosted by Robert Krulwich and featuring an original musical interlude, inspired by parallel worlds, by DJ Spooky.
