On September 14, 2015 at 09:50:45 UTC the two detectors of the Laser Interferometer Gravitational-Wave Observatory (LIGO) simultaneously observed a transient gravitational-wave signal. The signal sweeps upwards in frequency from 35 to 250 Hz and matches the waveform predicted by general relativity for the inspiral and merger of a pair of black holes and the ringdown of the resulting single black hole.<\/p>\n
I will discuss the LIGO detectors, the implications of the observation, and prospects for the new field of gravitational-wave astronomy.<\/p>\n","protected":false},"excerpt":{"rendered":"
