Whose theory first predicted the existence of gravitational waves?
PhysicsAstrophysics
Quick Answer
Albert Einstein’s general relativity. In 1916 he predicted ripples in spacetime caused by accelerating massive objects.
The Full Story
Einstein’s general relativity led to the prediction of gravitational waves in 1916, though he later questioned whether they would ever be detected. These waves are disturbances in spacetime produced by events such as merging black holes or neutron stars. They were directly observed by LIGO in 2015, nearly a century later. The detection confirmed a major prediction of Einstein’s theory and opened a new way to observe the universe.
