Physicist Brian Cox has rarely been shy about his enthusiasm for big, difficult ideas, but his reaction to a recent quantum ...

Quantum theory and general relativity have long described the universe with incompatible languages, one speaking in ...

Unifying gravity and quantum theory remains a significant goal in modern physics. Despite the success in unifying all other fundamental interactions (electromagnetism, strong force and weak force) ...

For close to a century, scientists have been trying to marry Albert Einstein’s General Theory of Relativity and quantum ...

When you buy through links on our articles, Future and its syndication partners may earn a commission. An abstract illustration of quantum particles entangling. New research aims to unite gravity with ...

Researchers at TU Wien have integrated quantum physics with general relativity, revealing significant departures from ...

In a bold step toward solving one of science’s most puzzling problems, researchers have proposed a new way to bring gravity into the same mathematical language as the other forces of nature. While the ...

In a new Physical Review Letters study, researchers propose an experimental approach that could finally determine whether gravity is fundamentally classical or quantum in nature. The nature of gravity ...

A new way of explaining gravity could bring us a step closer to resolving the heretofore irresolvable differences it has with quantum mechanics. Physicists Mikko Partanen and Jukka Tulkki at Aalto ...

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 ...

(via Sabine Hossenfelder) Last year, Jonathan Oppenheim’s theory of post-quantum gravity was the only theory that made it into my Best of 2024 summary. Post-quantum gravity is one of the most ...

Quantum gravity is the missing link between general relativity and quantum mechanics, the yet-to-be-discovered key to a unified theory capable of explaining both the infinitely large and the ...
