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.

A Google Deep Mind researcher and physics expert, Adam Brown, discusses what an AI Einstein would be like. Einstein coming up with General Relativity required coming up with new notation. Einstein’s ...

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 ...

The study of Einstein metrics on nilpotent Lie groups occupies a significant niche in differential geometry, melding abstract algebra with geometric analysis. Einstein metrics, defined by a ...
