// ORBITAL LOGISTICS AND PROPULSION TERM

Gravitational Wave

Gravitational waves are ripples in spacetime caused by extremely energetic cosmic events, like colliding black holes or neutron stars. They travel at the speed of light.

TECHNICAL DEFINITION

Disturbances in the curvature of spacetime, propagating as waves, generated by accelerating massive objects, such as merging black holes or neutron stars, as predicted by Einstein's theory of general relativity and detected by observatories like LIGO.
