Podcast: A Universe of Dark Energy

By Fraser Cain - November 21, 2006 at 1:29 AM UTC | Cosmology

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.

Astronomy Cast is a weekly podcast hosted by Fraser Cain from Universe Today, and Dr. Pamela Gay (of Slacker Astronomy fame). Each week we take a fact-based journey through the cosmos to explain the discoveries in astronomy, and understand how we know what we know.
