Definition of gravitational wave

: a disturbance in space-time in the form of a wave that propagates the gravitational field
  • Gravitational waves are a natural offshoot of the rubber-sheet construction of general relativity. Just as a massive object sitting on the fabric of spacetime creates a dimple, so moving or changing objects, under certain conditions, create wrinkles in the fabric. Those wrinkles, tiny distortions in spacetime, zoom away at the speed of light. Because these gravitational waves carry energy, anything emitting them will lose a tiny bit of its speed.
