Title: Astronomy Cast: Ep. 11: A Universe of Dark Energy

Organization: Astronomy Cast

Link: http://www.astronomycast.com

Description

From November 20, 2006.

The discovery of dark energy was one of the biggest surprises in astronomy. Instead of a nice, predictable expanding Universe, acted on only by gravity, astronomers turned up a mysterious repulsive force accelerating the expansion of the Universe. Fraser and Pamela explain
the evidence for a dark energy, and a few possible theories for what could be providing this repulsive force.

Bio: Fraser Cain is the publisher of Universe Today and Dr. Pamela Gay is a Senior Scientist at Planetary Science Institute and a Director of  CosmoQuest. They team up to do Astronomy Cast, a weekly facts-based journey through the cosmos
