Quantum gravity is the missing link between general relativity and quantum mechanics, the yet-to-be-discovered key to a ...

"We tried to resolve and explain the mismatch between the values ... study suggests In a study published in the journal ...

In a new Physical Review Letters study, researchers propose an experimental approach that could finally determine whether ...

Black hole singularities should not exist, according to theories of quantum mechanics. New tweaks to Einstein's equations of ...

A new theory suggests that gravity could possibly be the result of entropy. If true, this would mean that everything in the ...

Famed physicist Stephen Hawking took gravity to its ultimate limits. In doing so, he made a number of significant ...

Diagrammatic representation of the entropic quantum gravity action. The action for gravity is given by the quantum relative entropy between the metric of the manifold and the metric induced by the ...

I've long been fascinated by the fundamental mystery of our universe's origin. In my work, I explore an alternative to the ...

Last year, Jonathan Oppenheim’s theory of post-quantum gravity was the only theory that made it into my Best of 2024 summary.

Physicists have proposed a radical approach that questions decades of belief about how gravity, spacetime, and quantum mechanics fit together.

However, general relativity cannot explain everything ... "This work proposes that quantum gravity has an entropic origin and suggests that the G-field might be a candidate for dark matter ...

Scientists propose a relatively simple yet still complicated tabletop experiment to test the quantumness of gravity, aiming to reconcile general relativity and quantum mechanics.
