# General theory of relativity

From Citizendium

The **general theory of relativity** explains the phenomena of gravity as a an artifact of the geometry of space and time, which is not simply a Euclidean geometry but a Riemannian geometry that varies from location to location as it is affected by the presence of massive objects.^{[1]} The theory was proposed by Albert Einstein in 1915. An historical sketch of the theory and its experimental verification is found in the Introduction of Hughston and Tod.^{[1]} The work of Robert Pound provided the first experimental confirmation of the theory.
