Abstract
In September 2015, the detectors of the Laser Interferometer Gravitational-Wave Observatory (LIGO) detected, for the first time, gravitational waves generated by the merger of two black holes. To date, the detectors of the LVK collaboration—which unites LIGO (USA), the European Virgo, and Japan’s KAGRA—have detected gravitational wave signals from the mergers of black holes and neutron stars in the distant universe more than 400 times. In the intervals between observations, the detectors are upgraded, and their sensitivity is continuously improved. Comparing signals detected by gravitational-wave detectors with those predicted by the theory of General Relativity has made it possible to test the theory particularly in the regime of strong fields and high velocities. To date, the results of experimental observations are in good agreement with analytical and numerical calculations within the framework of General Relativity and do not require its modification. It is expected that next-generation detectors, to be built in the near future, will make it possible to test General Relativity with even greater precision and to find answers to many questions facing modern physics and astrophysics.
