An energy-carrying wave propagating through a gravitational field, produced when a massive body is accelerated or otherwise disturbed. Gravitational waves were first postulated by Einstein in 1916 and were first observed directly in September 2015.
experimenters report the first detection of a phenomenon that has been long predicted: bursts of gravitational waves generated by cosmic collisions of black holes
