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 present paper, we carried out a systematic investigation of pseudo-quasi-conformal curvature tensor has been made on the four-dimensional spacetime of general relativity. The spacetime ...

General relativity, also known as the general theory of relativity, is the geometric theory of gravitation published by Albert Einstein in 1915 and the current description of gravitation in modern ...

In this video, we explore Albert Einstein's theory of general relativity, focusing on his insights into gravity and ...

Gravitational distortions produced by distant galaxies show a slight—but notable—disagreement with Einstein's predictions.

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. This article is more than 4 years old. An illustration of heavily ...

The Event Horizon Telescope only recently gave us the first images of the environment immediately surrounding a black hole.

Energy-momentum distribution remains a fundamental yet challenging aspect of theoretical physics. In general relativity, the localisation of gravitational energy is obscured by the equivalence ...

The fabric of expanding space as illustrated over cosmic time. One of the consequences of the expansion is that the farther away a galaxy is, the faster it appears to recede from us, and that the ...
