gravitational wave
Cosmic fabric disturbance
Gravitational waves are ripples in spacetime caused by the acceleration of massive objects—particularly violent cosmic events like colliding black holes or neutron stars.
Einstein predicted them in 1916, but they weren't directly detected until 2015.
The waves stretch and compress space itself as they pass, though by amounts smaller than an atomic nucleus.
LIGO detected gravitational waves from two merging black holes.
