The existence of gravitational waves is one of the predictions of General relativity.
Observatory Advanced LIGO (Laser Interferometer Gravitational-Wave Observatory) and Virgo announced the first joint detection of gravitational waves — perturbations of space-time. The study is published in Physical Review Letters, according to the max Planck Society (Germany).
Signal GW170814 was registered on 14 Aug 2017. The outrage generated by merging pairs of black holes, one of which is 30.5 times, and another at 25.3 times heavier than the Sun. The event occurred at a distance of 1.8 billion light years, but the exact location is unknown.
Earlier, gravitational waves were detected exclusively LIGO, in the period from 14 September 2015 to June 1, 2017, the Observatory has registered three signals from merging black holes.
The existence of gravitational waves is one of the predictions of General relativity. Their discovery confirms not only the latest, but is considered to be one of the proofs of the existence of black holes.
