Speed of gravity

In classical theories of gravitation, the speed of gravity is the speed at which changes in a gravitational field propagate. This is the speed at which a change in the distribution of energy and momentum of matter results in subsequent alteration, at a distance, of the gravitational field which it produces. In a more physically correct sense, the ""speed of gravity"" refers to the speed of a gravitational wave, which in turn is the same speed as the speed of light (c).
