Abstract

According to general relativity, the gravitational force is a manifestation of the geometry of local spacetime. RG is a metric theory of gravity. It is based on Einstein's equations, which describe the relationship between the geometry of a four-dimensional pseudo-Riemannian manifold, representing spacetime, and the energy-momentum contained within that spacetime. Gravity is changes in spatial and temporal properties, which in turn change the paths of objects. Curvature is caused by the energy-momentum of matter. According to John Archibald Wheeler, spacetime tells matter how to move, and matter tells spacetime how to bend.
