A variation on the theory of quantum gravity — the unification of quantum mechanics and Einstein's general relativity — could help solve one of the biggest puzzles in cosmology, new research suggests.

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 ...

Add Yahoo as a preferred source to see more of our stories on Google. A new way of explaining gravity could bring us a step closer to resolving the heretofore irresolvable differences it has with ...

A new study has been published that further complicates the argument that gravity could be explained using quantum entanglement. If true, this could further complicate efforts to explain how gravity ...

Researchers have developed a method to model a central theory of quantum gravity in the laboratory. Their goal: to decipher previously unexplained phenomena in the quantum world. Gravity is no longer ...

Gravity is one of four fundamental interactions. The most precise description of this force is still provided by Einstein's General Theory of Relativity, published in 1915, an entirely classical ...

Quantum Gravity and General Relativity represent two foundational yet traditionally disparate pillars of modern physics. General Relativity, Einstein’s seminal theory, elegantly encapsulates ...

Repulsive gravity at the quantum scale would have flattened out inhomogeneities in the early universe First light The cosmic microwave background, as imaged by the European Space Agency’s Planck ...

(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 ...

The accelerating expansion of the universe could be explained by modifying general relativity so that gravity has mass – or so thinks a small group of physicists. Matthew Francis reports What lies ...
