How Gravitational Waves Are Produced: Foundations

Gravitational waves are propagating distortions of spacetime generated when mass-energy distributions change asymmetrically with time. Gravitational waves reveal otherwise dark compact objects, measure masses and spins, test gravity in strong fields, probe neutron-star matter, and provide independent distance information.

Accelerating masses produce time-varying spacetime curvature.

Binary-pulsar systems show orbital decay matching gravitational-radiation predictions, and LIGO/Virgo/KAGRA directly measure transient strains from compact-binary mergers.
