Dr. Marco Cavaglià, Dr. Katherine Dooley and Fellow Scientists with LIGO Detected Gravitational Waves from Black Holes

Dr. Marco Cavaglià, Dr. Katherine Dooley and fellow scientists with LIGO detected gravitational waves from black holes.
On September 14, 2015 at 03:50:45 a.m. CST the two detectors of the Laser Interferometer Gravitational-Wave Observatory simultaneously observed a transient gravitational-wave signal. The signal matches the prediction of general relativity for the coalescence of two black holes with the mass of about 30 Suns into a single black hole at a distance of over one billion light years from Earth. This is the first direct detection of gravitational waves and the first observation of a binary black hole merger.
