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.

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 theory that coherently describes all fundamental forces of nature is often called the Theory of Everything,” Aalto University postdoctoral researcher Mikko Partanen said. It has been the physicists ...

Quantum field theory (QFT) provides a comprehensive framework for describing the fundamental interactions of matter and radiation. In the context of atom‐field interactions, QFT elucidates how atoms ...

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 ...

The gravity quantum field is calculated in flat spacetime. The curved classical metric is calculated using the expectation value of the gravity quantum field. At long last, a unified theory combining ...

Complex Langevin dynamics has emerged as a powerful technique to tackle the sign problem inherent in quantum field theory simulations. By extending the configuration space into complex domains, this ...

A new hypothesis known as the Quantum Memory Matrix (QMM) could help explain some of the biggest mysteries of the universe, including the Black Hole Information Paradox. The idea is that space-time ...

Quantum gravity remains one of the big missing pieces of a Grand Unified Theory that could bridge quantum field theory and general relativity. Knowing that quantum gravity solutions must resemble ...

Quantum mechanics has a reputation that precedes it. Virtually everyone who has bumped up against the quantum realm, whether in a physics class, in the lab, or in popular science writing, is left ...

Researchers at UBC have found a way to mimic the elusive Schwinger effect using superfluid helium, where vortex pairs appear out of thin films instead of electron-positron pairs in a vacuum. Their ...
