New Windows on the Universe

David Wiltshire from Roy Kerr's institute at the University of Canterbury describes the LIGO discovery of a beautiful gravitational wave signal of a binary black hole merger:

As researchers with the Laser Interferometer Gravitational-Wave Observatory (LIGO) announce they have spotted gravitational waves – ripples in space itself set off by violent astrophysical events – University of Canterbury Professor of Physics Dr David Wiltshire discusses what it means.

The announcement that gravitational waves have been directly captured for the first time ever, from the collision of two black holes, opens a new age of astronomy. From now on we will be able to “listen” to the Universe with “ears” that are not limited by the electromagnetic spectrum, completely changing our understanding. It is a moment in history every bit as important as when Galileo first pointed his telescope at the stars and planets, or when the first radio, X-ray, infrared or gamma ray telescopes were first turned on by 20th century astronomers.
