The Fabric of the Cosmos: The Illusion of Time
Airs Wednesday, July 18 at 8:00 PM
Brian Greene takes us on the ultimate time traveling adventure, hurtling 50 years into the future before stepping into a wormhole to travel back to the past. Along the way, he will reveal a new way of thinking about time in which moments past, present, and future — from the reign of T.Rex to the birth of your great-great-grandchildren — exist all at once.
