**relativity**is a**theory**of gravitation developed by Einstein in the years 1907–1915. The development of general**relativity**began with the equivalence principle, under which the states of accelerated motion and being at rest in a gravitational field (for example, when standing on the surface of the Earth) are physically identical.In theoretical
