Definitions for "Gravity wave"
Ripples in space-time created by the stretching and squeezing effects of massive objects, notably supernovae, binary black holes, and binary neutron stars. Gravity waves are transverse waves, meaning that they stretch and squeeze space-time in directions perpendicular to the wave's motion. Einstein's Theory of General Relativity predicts the existence of gravity waves, but they have not yet been detected. See also
The gravitational analog of an electromagnetic wave whereby gravitational radiation is emitted at the speed of light from any mass that undergoes rapid acceleration.
A wave for which the restoring force is gravity. See forced wave.
