In a new book release, two scientists combine forces to explain the discoveries, developments and theories made in the realm ...

In it, he suggested that gravity is not a force, as Newton had believed, but the result of a curvature of the space-time continuum -- the four dimensional world in which we live. He used a thought ...

That describes the largest structures in the universe in terms of curvature of space and time. On the other hand, we have quantum theory. Which very successfully describes the elementary particles.

Black hole singularities should not exist, according to theories of quantum mechanics. New tweaks to Einstein's equations of general relativity could finally do away with them, and explain what truly ...

He discussed space of four or more dimensions, and paved the way for the General Theory of Relativity Just 100 years ago the young Bernhard Riemann gave his famed paper on the foundations of geometry.

The amount of matter within the universe sculpts its overall curvature. And space-time itself can be either expanding or contracting. When Einstein announced general relativity in 1915 ...

Gravitational physicists explore the implications of the general theory of relativity, in which gravitation is a consequence of the curvature of space and time. This curvature thus controls the motion ...
