A propagating disturbance of spacetime curvature generated by time-varying nonspherical mass-energy distributions and traveling at the speed of light in general relativity.
Far from a source and in the weak-field limit, gravitational waves are described by transverse radiative metric perturbations; strong-field sources require the full nonlinear Einstein equations.

This is an authored directed relation from the source endpoint to the target endpoint.
Einstein’s equations admit propagating gravitational radiation; weak-field wave equations describe distant radiation, while compact-binary generation and merger require nonlinear general relativity.
A theory, law, or interaction describes the behavior of the target within a stated regime. The edge detail must state important limits or qualifications.

This is an authored directed relation from the source endpoint to the target endpoint.
LIGO measured the strain waveform from a binary-black-hole coalescence, directly detecting gravitational waves and matching a general-relativistic inspiral–merger–ringdown signal.
The source theory, law, entity, prediction, or structural claim is directly tested, supported, constrained, or established by the target experiment or observation. Experimental support is not final logical proof; the edge detail states exactly what was measured.

The measured orbital-period decrease of PSR B1913+16 agreed with the energy loss predicted for emitted gravitational radiation, providing indirect evidence before direct interferometric detection.
The source theory, law, entity, prediction, or structural claim is directly tested, supported, constrained, or established by the target experiment or observation. Experimental support is not final logical proof; the edge detail states exactly what was measured.
