[PAR] [TLE] General relativity [SEP] General relativity (GR, also known as the general theory of relativity or GTR) is the geometric theory of gravitation published by Albert Einstein in 1915 and the current description of gravitation in modern physics.  General relativity is considered probably the most beautiful of all existing physical theories.  General relativity generalizes special relativity and Newton's law of universal gravitation, providing a unified description of gravity as a geometric property of space and time, or spacetime.  In particular, the "" is directly related to the energy and momentum of whatever matter and radiation are present.  The relation is specified by the Einstein field equations, a system of partial differential equations. [PAR] [TLE] Einstein field equations [SEP] The Einstein field equations (EFE; also known as Einstein's equations) is the set of 10 equations in Albert Einstein's general theory of relativity that describes the fundamental interaction of gravitation as a result of spacetime being curved by mass and energy.  First published by Einstein in 1915 as a tensor equation, the EFE equate local "" (expressed by the Einstein tensor) with the local energy and momentum within that spacetime (expressed by the stress–energy tensor).
