Researchers have developed a new quantum theory of gravity which describes gravity in a way that's compatible with the Standard Model of particle physics, opening the door to an improved understanding ...

At long last, a unified theory combining gravity with the other fundamental forces—electromagnetism and the strong and weak ...

A bold new theory could bridge quantum physics and gravity at last. At Aalto University in Finland, two physicists believe ...

Quantum ideas describe particles and fields in tiny packages, but general relativity paints gravity as smooth curves in space ...

The Standard Model is a gauge theory that describes the strong, weak, and electromagnetic forces, and it has specific ...

Note: The verification e-mail to complete your account registration should arrive immediately. However, in some cases it ...

The gravity quantum field is calculated in flat spacetime. The curved classical metric is calculated using the expectation ...

In the quest toward finding the correct theory of quantum gravity, physicists have been testing the holographic principle which, they say, is a key property of any valid theory of quantum gravity.

A complete theory of quantum gravity remains one of the biggest challenges ... Under certain conditions, these modified ...

Since the early days of general relativity, leading physicists, like Albert Einstein and Erwin Schrödinger, have tried to unify the theory of gravitation and electromagnetism. Many attempts were ...

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 ...
