gravity theories of Newton and Einstein are different. The discrepancies between theory and observation were resolved and the theory of universal gravitation Newton was accepted until replaced in 1915 by the theory of general relativity of Einstein, which is consistent with that of Newton in the domain in which all bodies move very slowly compared with the speed of light. In the solar system, planets and satellites travel at speeds of tens of kilometers per second, while the speed of light is about 300,000 kilometers per second. Einsteinian corrections to Newton's theory are thus practically negligible, and can only be detected in a very small number of observations. Einstein's theory has passed all the tests that have been subjected.
