The first evidence for gravitational waves came in 1974, when physicists Russell Hulse and Joseph Taylor discovered a pair of neutron stars, 21,000 light years from Earth, that seemed to behave in a curious pattern. They are a fundamental part of the General Theory of Relativity, and their discovery can prove this theory and identify its weak points, which can thus be eliminated or corrected – an important step towards that unitary theory that reconciles classical physics, … We did it.”. All this time we were only observing some of gravity’s most superficial effects. Scientists pioneer use of deep learning for real-time gravitational wave discovery. In 1916, Albert Einstein published his monumental work on the general theory of relativity. GW 190412 (gravitational wave events are named for their date of detection) was the first black hole collision in which the two black holes had wildly mismatched masses; all other black hole collisions detected prior had involved more or less equal-mass binaries.. GW 190425 is thought to be from a collision between two neutron stars, only the second ever detected (the first was in August 2017). Gravitational waves were first predicted in Albert Einstein's theory of gravity, general relativity. Since this first discovery, LIGO has detected other gravitational wave signals, also generated by pairs of spiraling, colliding black holes. Astrophysics that is only accessible through gravitational waves (see Leo C. Stein's answer to What type of new physics can be done with gravitational waves?). Advertisement. Gravitational waves are part of the Theory of General Relativity, created by Albert Einstein in 1915. In this theory, gravity is treated differently to how we imagined and this results in space-time become “curved”. Both SDSC and NCSA have continued to support research on gravitational waves, including one of NCSA’s current relativity researchers, Eliu Huerta, who is a co-author on the observational discovery published today online in Physical Review Letters (“Observation of Gravitational Waves from a Binary Black Hole Merger”).
