General relativity is the geometric theory of gravitation published by Albert Einstein in 1915 and is the current description of gravitation in modern physics. It generalizes special relativity and refines Newton's law of universal gravitation, providing a unified description of gravity as a geometric property of space and time, or spacetime.
Developed by Albert Einstein between 1907 and 1915, with contributions from many others.
A fundamental pillar of modern physics, essential for understanding the large-scale structure of the universe, black holes, and gravitational waves.
