= Tests of general relativity
{wiki=Tests_of_general_relativity}
Tests of general relativity refer to experiments and observations that are designed to confirm or challenge the predictions made by Einstein's theory of general relativity (GR). General relativity, proposed in 1915, is a theory of gravitation that describes gravity as the curvature of spacetime caused by mass and energy. Over the years, many tests have been conducted to validate its predictions in various contexts.
