Gravitational waves were first detected on September 14, 2015 by both of the twin Laser Interferometer Gravitational-wave Observatory (LIGO) detectors, located in Livingston, Louisiana, and Hanford, Washington. These waves were generated by a pair of black holes that orbited each other at very high speeds – close to the speed of light!
So how are these waves generated? Steve Mould has made a model that (very impressively) demonstrates how these gravitational waves were generated:
