Scientist using the Laser Interferometer Gravitational-Wave Observatory (LIGO) have observed the warping of space-time generated by the collision of two black holes more than a billion light-years from Earth. This is the first direct detection of gravitational waves, first proposed by Albert Einstein in his Theory of General Relativity, published in 1916.
