Introduction to LIGO & Gravitational Waves
Newton, Einstein and Gravitational Waves
But Einstein's Theory of General Relativity - the most commonly accepted description of gravity - asserts that no information can travel faster than the speed of light, including information on the positions of mass in the universe, which is communicated through the gravitational field. General Relativity predicts that a change in gravitational field will travel through the universe at the speed of light. It is exactly these changes in gravitational field that are gravitational waves.
