Its foundation is that the laws of nature in an accelerating frame are equivalent to the laws of a gravitational field. This is known as the Equivalence Principle.In 1915, Einstein proposed a new theory of gravity, which is now called the General Theory of Relativity: In 1666, Sir Isaac Newton had proposed a theory of gravity called Newton's Universal Law of Gravitation.his was the fundamental principle for his General Theory of Relativity, which was published in 1916.
