The geometry of spacetime forms the very foundation of modern gravitational theory, where the elegant interplay between curvature and matter is described by Einstein’s field equations. In this ...

General Relativity reinterprets the force of gravity not as a traditional force but as a manifestation of the curvature of spacetime. Its formulation rests on a rigorous mathematical framework built ...

In the paper the Einstein tensor for the metric which provides a conic motion is found. From the result it is concluded that the matter creating such metric is continuously spread in the universe.
