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

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.

The force we experience most intimately remains the most mysterious. Physicists understand how vast migrations of particles called photons light up our homes, and how swarms of “gluon” particles hold ...

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 ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.
