: Massive objects like stars and planets warp the "fabric" of spacetime. Objects moving through this space follow curved paths (geodesics), which we perceive as the "pull" of gravity.
: This fundamental idea states that the effects of gravity are locally indistinguishable from the effects of acceleration. Introduction to General Relativity
: Einstein's equations describe the precise relationship between the distribution of matter/energy and the resulting curvature of spacetime. Key Predictions and Applications : Massive objects like stars and planets warp
is the modern theory of gravitation developed by Albert Einstein between 1907 and 1915 . Unlike Newtonian gravity, which views it as an attractive force between masses, GR describes gravity as a result of the curvature of spacetime caused by mass and energy.
