Dark Energy and the Runaway Universe-Bay Area Science Festival October 26, 2011

Alex Filippenko, UC Berkeley Professor of Astronomy, tells how observations of supernovae—distant exploding stars—show that the expansion of the universe is speeding up, rather than slowing down as expected. The universe seems to be dominated by a repulsive “dark energy” that stretches the very fabric of space faster and faster with time. Presented in association with the San Francisco Public Library’s One City One Book Program.
