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 ...

Black holes — regions of space-time with extreme curvature — first arose as a concept from solutions to Einstein's field equations suggested by German physicist and astronomer Karl ...

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 ...

A powerful mathematical technique is used to model melting ice and other phenomena. But it has long been imperiled by certain ...

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 ...
