The research was done by Caltech’s Clifford Cheung and Aaron Hillman along with Grant Remmen at New York University. They ...

The accelerating expansion of the Universe, first observed in 1998, remains one of the most profound mysteries in modern ...

“String theory was developed for people to understand the physics of the strong interaction. [...] People started from a very simple model where they saw that if you take two quarks (a fundamental ...

- (physics) the theory that any two particles of matter attract one another with a force directly proportional to the product of their masses and inversely proportional to the square of the distance ...

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 ...

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 ...

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 ...
