Traditional black holes, as predicted by Albert Einstein's theory of General Relativity, contain what are known as ...

The problems of gravity and acceleration would not go away. After thinking about the problems for 10 years, he published the general theory of relativity. In it, he suggested that gravity is not a ...

A rare Einstein ring spotted near our galaxy offers a unique chance to test Einstein’s general relativity and study the ...

Facts don't go away when scientists debate rival theories to explain them. Einstein's theory of gravitation replaced Newton's in this century, but apples didn't suspend themselves in midair ...

For over a century, quantum mechanics and Einstein’s general relativity have stood as the cornerstones of modern physics, yet ...

By unifying all fundamental forces of nature, including gravity, string theory could provide the long-sought quantum description of gravity that has eluded scientists for decades. Through a novel ...

Sheldon Glashow has strong opinions about string theory. Like how it has failed in its primary goal of incorporating gravity into the standard model of elementary particles. How its inability to ...

general relativity is one of two pillars of modern physics – our working theory of gravity and of the very large, of planets, galaxies and the universe as a whole. It is an extension of Einstein ...

General relativity describes gravitation in a geometrical framework generalizing special relativity and classical mechanics. This term includes theoretical studies of gravity, experimental studies ...

The trouble boils down to gravity. It’s the only one of the four fundamental forces of nature described by general relativity, and the only one that quantum theory cannot address. Coming up with ...
