Time Since Einstein

Saturday, June 13, 2009
4:00 pm - 5:30 pm EST

Albert Einstein shattered previous ideas about time, but left many pivotal questions unanswered: Does time have a beginning? An end? Why does it move in only one direction? Is it real, or something our minds impose on reality? Journalist John Hockenberry leads a distinguished panel, including renowned physicist Sir Roger Penrose and prominent philosopher David Albert, as they explore the nature of time.

This program is part of the Big Ideas Series, made possible with support from the John Templeton Foundation.
