Here's How It Felt to Discover Gravitational Waves (Kavli Hangout)

When Rainer "Rai" Weiss and colleagues first proposed an audacious experiment to detect ripples in space-time, called gravitational waves, in the late 1970s, they knew the whole endeavor was a long shot. Now, four decades later, millions of people worldwide have read about the historic detection of gravitational waves as the result of Weiss and his fellow scientists' efforts: the Laser Interferometer Gravitational-Wave Observatory (LIGO).
