The Einstein Field Equations (EFE) are a set of ten interrelated equations in Albert Einstein's theory of General Relativity. They describe how matter and energy in the universe influence the curvature of spacetime. This curvature, in turn, affects the motion of objects, explaining the gravitational force. The EFE can be summarized by the equation G_\mu\nu = 8\pi G T_\mu\nu , where G_\mu\nu represents the curvature of spacetime, T_\mu\nu represents the energy and momentum of matter, and G is the gravitational constant. These equations form the foundation for understanding gravitational phenomena in cosmology and astrophysics.
