Brian Greene engages physicist and former LIGO spokesperson Gabriela González in a conversation about LIGO and Virgo’s new announcement of the most massive gravitational wave source to date and discusses what we’ve learned about the cosmos.

This program is part of the Big Ideas Series, which is supported, in part, by the John Templeton Foundation.

WSU Live Sessions are conversations hosted by Brian Greene with World Science U faculty exploring matter, mind, and the cosmos. Subscribe to our WSU newsletter for updates and information on future Live Sessions: http://eepurl.com/U3qzT
