Scientists detect collision of two supermassive black holes

 Astrophysicists and astronomers have detected the strange vibrations in space-time itself, caused by the collision of two supermassive black holes! These are the black holes at the centers of galaxies, with large masses from millions to billions of times more than the Sun. Gravitational wave detectors like LIGO have been sensing these since 2015, but now new techniques were used for the latest discovery. By looking at minute changes in the timing of a sample of pulsars, which are fast-spinning neutron stars that emit periodic, clock-like bursts of radio waves, the distortions of those precise bursts are measured by radio wave detectors, and are consistent with what Einstein's theory of general relativity predict. Amazing, and this constant 'churning' of the space-time sea is now being studied for all sorts of different events and signals!
