The speed of gravitational waves in the general theory of relativity is equal to the speed of light in vacuum, c. [17] Within the theory of special relativity, the constant c is not only about light; instead it is the highest possible speed for any interaction in nature.
General relativity plays a central role in modelling all these phenomena, [128] and observations provide strong evidence for the existence of black holes with the properties predicted by the theory. [129] Black holes are also sought-after targets in the search for gravitational waves (cf. Gravitational waves, above).
General relativity also predicts novel effects of gravity, such as gravitational waves, gravitational lensing and an effect of gravity on time known as gravitational time dilation. Many of these predictions have been confirmed by experiment or observation, most recently gravitational waves .
In general relativity, the Einstein–Rosen metric is an exact solution to the Einstein field equations derived in 1937 by Albert Einstein and Nathan Rosen. [1] It is the first exact solution to describe the propagation of a gravitational wave.
Video simulation showing the warping of space-time and gravitational waves produced, during the final inspiral, merge, and ringdown of black hole binary system GW150914 [23] Albert Einstein predicted the existence of gravitational waves in 1916, [24] [25] on the basis of his theory of general relativity. [26]

First discovered in 2015 by the Laser Interferometer Gravitational-Wave Observatory, or LIGO, gravitational waves are physical ripples in spacetime caused by objects with mass moving through space ...
Gravitational plane waves are described as "non-flat solutions of Albert Einstein’s empty spacetime field equation". [1] [2] [3] [4] They are a special class of a ...
