Video: Brian Greene Explains The Hidden Reality to Stephen Colbert

Once, “the universe” was all there was. It included everything. Now, cutting-edge physics tells us that our universe may be but one among many—parallel universes populating a vast multiverse. Does this mean there are parallel versions of ourselves? Are these parallel versions of ourselves evil? Is reality just a hologram? These important questions and more were investigated when Brian Greene, author of The Hidden Reality, visited The Colbert Report. Watch the interview below.

The Hidden Reality will be available in paperback on November 1st; click to read an excerpt. Brian Greene will appear on PBS in a new series for NOVA, debuting on November 2nd at 9:00pm Eastern. Click to watch the trailer for “Fabric of the Cosmos.”
