Einstein Field Equations
The Einstein Field Equations (EFE) are fundamental equations in General Relativity that describe how matter and energy in the universe influence the curvature of space and time. They show that massive objects, like stars and planets, warp the fabric of spacetime around them, causing the gravitational effects we observe. Essentially, the EFE relate the distribution of mass and energy (on one side) to the shape of spacetime (on the other), thus explaining how gravity works not as a force, but as the result of this curvature created by mass and energy.

The Einstein field equations describe how matter and energy in the universe influence the curvature of space and time, essentially explaining gravity. In simple terms, they show that massive objects, like planets and stars, bend the fabric of space-time around them, causing other objects to move along curved paths. This is why planets orbit stars and why light bends around massive bodies. The equations form the core of Einstein's General Theory of Relativity, fundamentally changing our understanding of gravity from a force to a geometric property of space-time itself.
