1907 – Albert Einstein introduces the principle of equivalence of gravitational and inertial mass and uses it to predict gravitational lensing and gravitational redshift, [41] [42] historically known as the Einstein shift. [43] 1907-8 – Hermann Minkowski introduces the Minkowski spacetime and the notion of tensors to relativity. His paper ...

General relativity is a theory of gravitation that was developed by Albert Einstein between 1907 and 1915, with contributions by many others after 1915. According to general relativity, the observed gravitational attraction between masses results from the warping of space and time by those masses.
In 1907, in what he described as "the happiest thought of my life", Einstein realized that someone who is in free fall experiences no gravitational field. In other words, gravitation is exactly equivalent to acceleration. Einstein's two-part publication in 1912 [115] [116] (and before in 1908) is really only important for historical reasons. By ...

Physics is a branch of science in which the primary objects of study are matter and energy.These topics were discussed by philosophers across many cultures in ancient times, but they had no means to distinguish causes of natural phenomena from superstitions.
