The existence of gravitational waves is one of the last unsolved mysteries of the cosmos. The famous physicist Albert Einstein predicted these waves in 1916. This research aims to understand how gravitational waves occur in space-time from various sources. This study describes the detection of gravitational waves from several sources. This study uses the literature review method, through several stages such as literature study, data collection, and analysis. The result of this study is that the LIGO (Laser Interferometer Gravitational-Wave Observatory) and Virgo detectors detect gravitational waves through the collision source of two neutron stars orbiting each other emitting gravitational waves that experience a constant loss of energy so that the neutron stars are getting closer according to the shrinking orbital period and increasing wave frequency tall. For the source of the fusion of two black holes, two large interferometric detectors from the LIGO (Laser Interferometer Gravitational-Wave Observatory) scientific collaboration detected gravitational wave signals based on an analysis of the general theory of relativity showing they originate from two black holes combining 29 and 35 solar masses merging 1.3 billion light years on Earth, after a black hole merger produces a mass of 62 Suns. And the source of gravitational waves from binary mergers of black holes and neutron stars, the LIGO (Laser Interferometer Gravitational-Wave Observatory) dan Virgo detector observes gravitational wave signals. The merger of a neutron star and black hole produces light across the electromagnetic spectrum.
