Physicist Bryan Greene explains the Gravitational Wave discovery on Stephen Colbert

By now I’m sure you’ve heard about the discovery of Einstein’s gravitational waves.  When Einstein predicted that space-time could be seen as a fabric that bends around heavy gravitation it was a purely theoretical exercise.  100 years later, we’ve finally discovered a way to measure ripples in this ‘fabric’. The measurements were made at LIGO, the Laser Interferometer Gravitational-Wave Observatory by Caltech and MIT.

A seasoned veteran of explaining science to non-scientists, Greene clearly explains how this measurement was made and what it could mean for the future of the scientific study of gravity.
