An international team of scientists announced Thursday that they have detected gravitational waves from two black holes that collided a billion light years away. The waves, also known as "ripples" in the fabric of spacetime, confirm a key prediction of Einstein's general theory of relativity. We discuss the significance and implications of the discovery.

David Reitze, physicist and executive director, Laser Interferometer Gravitational-Wave Observatory (LIGO) at Caltech
