Detecting gravitational waves
More about gravitational wave detectors on earth and in space
Albert Einstein predicted their existence back in 1916, and on 14 September 2015 they were directly detected for the first time: Gravitational waves. Two large interferometric detectors of the LIGO Scientific Collaboration with major contributions from German researchers detected the signal known as “GW150914”. The waves originate from the merger of two black holes and are the first direct observation of these exotic objects.
