Gravitational waves are 'ripples' in space-time caused by some of the most violent and energetic processes in the Universe. Albert Einstein predicted the existence of gravitational waves in 1916 in his general theory of relativity. Einstein's mathematics showed that massive accelerating objects (such as neutron stars or … See more The strongest gravitational waves are produced by catastrophic events such as colliding black holes, the collapse of stellar cores (supernovae), coalescing neutron stars or white dwarf stars, the slightly wobbly rotation of … See more Though gravitational waves were predicted to exist in 1916, definitive proof of their existence wouldn't exist until 1974, 20 years after … See more Lucky for us here on Earth, while the processes that generate gravitational waves can be extremely violent and destructive, by the time the waves reach Earth they are billions of times smaller.
