How the Universe Began
August 17, 2012
[REBROADCAST] Who hasn’t looked up at the dark, night sky and marveled at the enormity of the universe and wondered about those very first moments when it was all began. Astronomer CHRIS IMPEY has spent his career thinking about these kinds of questions. In his recent book “How it Began: A Time Traveler’s Guide through the Universe” he takes readers back billions of years to the Universe in its infancy. Impey sat down with Marty this spring and talked about the early years, the Big Bang, string theory, relativity, dark energy and more.
