The Einstein field equations

The Einstein field equations describe how gravity works in our universe. They express how massive objects like stars and planets cause space and time to bend or curve around them. This curvature tells matter how to move and also affects the flow of time itself. Essentially, these equations link the distribution of mass and energy to the shape of spacetime, providing a mathematical framework for understanding gravity not as a force, but as the geometry of the cosmos influenced by matter and energy.
