A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum ...

The main idea is to have a gravity gauge theory with a symmetry that is similar to the Standard Model symmetries, instead of ...

A new paper uses a simplified model to prove that gravity can be unified between quantum and standard physics. The simpler ...

Bringing gravity into the fold has been the goal of generations of physicists, who have struggled to reconcile the incompatibility of two cornerstones of modern physics: quantum field theory and ...

Black hole and Big Bang singularities break our best theory of gravity. A trilogy of theorems hints that physicists must go ...

One of the most profound open questions in modern physics is: "Is gravity quantum?" The other fundamental ...

A new theoretical proposal suggests scrapping nearly everything we think we know about gravity in order to understand the ...

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

At Utah State University, researchers are using a radical idea known as the holographic principle to bridge the gap. By ...

While the electromagnetic, weak, and strong forces are described by the Standard Model of particle physics, gravity remains an outlier—resisting efforts to be fully explained by quantum theory.

Developed by Ginestra Bianconi, a mathematical physicist at Queen Mary University of London, UK, and published in Physical Review D, this modified version of gravity provides new quantum information ...

Finding out whether gravity – and therefore space-time itself – is quantum in nature has long been thought impossible. But ...
