To General Relativity — Introduction

: 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.

: Einstein's equations describe the precise relationship between the distribution of matter/energy and the resulting curvature of spacetime. Key Predictions and Applications Introduction to General Relativity

: This fundamental idea states that the effects of gravity are locally indistinguishable from the effects of acceleration. : Massive objects like stars and planets warp
