A quantum theory of gravity would clear the path to answering some of the biggest questions in physics.

A new way of explaining gravity could bring us a step closer to resolving the heretofore irresolvable differences it has with ...

The images, which show interactions between free-range particles that had only been theorized until now, will reportedly ...

The Standard Model explains three fundamental forces—electromagnetism, the weak force, and the strong force—but gravity ...

Schrödinger, the father of quantum mechanics, put forward his unified field theory in the 1940s, but without complete success. Many different approaches have been proposed, including five ...

Dreams of a unified field theory Einstein's aim was to explain electromagnetism as a geometric property of four-dimensional spacetime. He continued this work until his death in 1955.
