Science at the Theater: New Light on Dark Energy April 25, 2011

Is dark energy really accelerating the universe? Three Lawrence Berkeley National laboratory cosmologists bring you the latest insights on nature's greatest mystery on April 25, 7 p.m. at the Berkeley Repertory Theatre in Berkeley, CA.

Greg Aldering: We know the universe is accelerating because of Type 1a supernovae. Aldering is one of the best in the business when it comes to hunting down these exploding stars.

Shirley Ho: A great yardstick to measure the cosmos is the mesh of the network of galaxies, also called baryon oscillation. Ho uses this yardstick to understand the accelerating universe.

Eric Linder: Maybe dark energy isn't driving the universe. Maybe it's something even stranger. Author of The First Principles of Cosmology, Linder asks out-of-the-box questions about the cosmos.

Moderated by Andrew Fraknoi, the Bay Area's most popular astronomy explainer.
