Albert Einstein on a bill of 5 Israeli Pounds. A truly spectacular unpublished autograph manuscript produced by German physicist Albert Einstein (1879-1955) and exploring his celebrated Unified Field ...

A pair of mathematicians have proposed a unified theory of dark matter and dark energy that alters Einstein's equations describing the fundamentals of gravity. They suggest the law of energy and ...

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 ...

Scientists typically explain gravity in terms of Einstein’s theory of general relativity. In this model, objects in the universe cause the fabric of spacetime to warp around them, creating a ...

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 ...
