Gravitational wave is ripple in the curvature iof spacetime that are generated in certain gravitation intersections and propagate as waves outward from their source at the speed of light Predicted in 1916 by Albert Einstein on the basis of his theory of general relativity, gravitational waves transport energy as grvitational radiation a form of radiant energy similar to electromagnetic radiation. Newton's law of universal gravitation, part of classical mechanics, does not provide for their existance, since that law is predicted on the assumtion that physical intractions propagate at infinite speed -- showing one of the ways the methods of classicasl physics are unable to explain phenomenon associate with relativity.
