- Albert Einstein predicted the existence of gravitational waves in 1916 as a consequence of his theory of General Relativity. This statement is correct. 2. The Newtonian theory of Gravitation describes gravity as an instantaneous force between masses. It does not predict the existence of gravitational waves which are ripples in spacetime propagating at the speed of light. This statement is incorrect. 3. Gravitational waves are extremely weak and require highly sensitive detectors. Interferometers, such as those used in the LIGO (Laser Interferometer Gravitational- Wave Observatory) and Virgo experiments, are the primary instruments used for their detection.
