In search of a united scientific theory, a new quantum gravity paper might have proposed an interesting aspect that made the ...

Quantum theory fails to explain how the reality we experience emerges from the world of particles. A new take on quantum ...

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.

Fundamental physics faces a stubborn paradox: the current impossibility of reconciling the rules of the quantum world with ...

Kellogg Stelle was a professor of physics at Imperial College London for decades until his death last month. In 1977, he developed a particle theory of gravity that’s renormalizable, but the theory’s ...

For decades, physicists have faced one of science’s greatest puzzles: merging quantum mechanics, which describes tiny particles, with general relativity, which explains the universe’s vast structures.

(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 ...

A new theory suggests that gravity could possibly be the result of entropy. If true, this would mean that everything in the universe would fall apart if it all remained unchanged. This theory tries to ...

Quantum gravity and field theory represent a frontier where the principles of quantum mechanics are reconciled with Einstein’s description of gravity. Researchers are seeking a consistent framework ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. The greatest scientific legacy that Albert Einstein left us is this: ...

Physicists tested light speed using cosmic gamma-ray bursts. Study confirms Einstein's prediction that all light colors travel at same speed.
