... resolution is that the domain of validity is more limited than we originally thought. Newton’s laws being a special case of Einstein’s theory of special relativity for low velocities is an example of this. Many changes are abrupt, but we forget very quickly all the things that were wrong and how dif ...

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).
