Gravitational waves are ripples in spacetime caused by accelerating massive objects. They were predicted by Einstein and directly detected in 2015.

Vanliga frågor
How are gravitational waves detected?
LIGO uses laser interferometry to measure changes in arm length from gravitational wave strain.
Do gravitational waves carry information?
Yes, they encode details about the source: masses, spins, orbital parameters, and cosmological distance.
