Wonderfest: 'Chasing Einstein', Dark Matter

Einstein's vision of gravity has shaped our understanding of the universe for 100 years. Chasing Einstein is a new documentary that follows Nobel laureates and six other physicists to the LIGO gravity wave detector, to the CERN particle accelerator, and beyond in order to better understand gravity and the cosmos. Following a special Science On Screen presentation of Chasing Einstein, its producer/director Steve Brown will discuss Einstein's cosmic legacy - and future - with UC Berkeley physicist Robert McGehee.
