General relativity is the geometric theory of gravitation published by Albert Einstein in 1915, and it remains the current model of gravitation in modern physics. The core of General Relativity is founded on the famous Einstein field equations (EFE) that describe the curvature of spacetime caused by mass-energy. While the commonly used "rubber sheet" analogy has long been employed to describe spacetime, in which mass-energy is the weight placed in the center of a rubber sheet causing deformation
