Albert Einstein predicted the existence of gravitational waves in 1916 in his general theory of relativity. ... The strongest gravitational waves are produced by cataclysmic events such as colliding black holes, supernovae (massive stars exploding at the end of their lifetimes), and colliding neutron stars.

Did Einstein believe in gravitational waves?

Einstein soon hit on the correct formulation, but two decades later he rejected the physical reality of gravitational waves, and he remained skeptical about them for the rest of his life. Like most scientific concepts, that of gravitational waves emerged over many years, through the work of numerous architects.

Was Einstein wrong about gravitational waves?

Einstein predicted that noise and vibrations on Earth would prevent us from ever being able to detect gravitational waves. But these observatories proved him wrong. Scientists have detected cataclysmic collisions between black holes and neutron stars.
