G g - noun gravitational wave (in general relativity) a propagating wave of gravitational energy produced by accelerating masses, especially during catastrophic events, as the gravitational collapse of massive stars. 1
- noun gravitational wave a wave-like motion in a gravitational field, produced when a mass is accelerated or otherwise disturbed; they travel through spacetime at the speed of light and the strongest sources are those with the strongest gravitational fields, although the waves are very weak; predicted by Einstein in 1916 but not first observed directly until 2015 0
- noun gravitational wave a hypothetical wave of very weak gravitational energy that travels through space at the speed of light: thought to be caused by the sudden acceleration of a large mass 0
- noun gravitational wave (physics) A postulated fluctuation in spacetime that propagates as a wave at the speed of light. 0
