One hundred years after Sir Albert Einstein predicted the existence of gravitational waves, physicists with the Advanced Laser Interferometer Gravitational-Wave Observatory (LIGO) revealed on 11 February that their twin detectors have heard the gravitational ringing produced by the collision of two black holes about 400 mega parsecs (1.3 billion light-years) from Earth. These elusive ripples in space time fulfilled the last prediction of Einstein's general theory of relativity.
