To Infinity and Beyond: The Accelerating Universe

Thursday, May 28, 2015
8:00 pm - 9:30 pm

Dark energy is cosmology’s biggest mystery—an anti-gravitational force that confounds the conventional laws of physics. It makes up more than two-thirds of the cosmos, but science is still grappling to explain what dark energy actually is. In this program, top physicists search for clues to this mystery in both the earliest moments of the universe and far into the future of the cosmos.

This program is part of the Big Ideas Series, made possible with support from the John Templeton Foundation.
