Gravitational waves
Gravitational waves are propagating disturbances in spacetime produced by accelerating masses, as predicted by general relativity. They transport energy away from dynamic systems such as compact binary mergers.
Gravitational waves are discussed in astrophysics, general relativity, and observational astronomy.
Status
Gravitational waves are detected through interferometric observatories measuring minute spacetime strains. Observations are used to study compact objects, test relativistic models, and probe high-energy astrophysical events.
