"This is the holy grail of theoretical physics." Physicists have been looking for a recipe of quantum gravity and a unification theory for some time now. String theory, which replaces particles with ...

Scientists demonstrate that quantum networks of clocks offer a new way to explore the interplay between quantum mechanics and curved space-time. Quantum networking is advancing rapidly across the ...

Black holes, these extreme cosmic entities, might well hold the missing clues to solve one of physics' greatest mysteries: ...

In physics, there are two great pillars of thought that don't quite fit together. The Standard Model of particle physics ...

Researchers are using machine learning, symbolic regression, and high-performance computing to explore and classify string ...

Some physicists think our reality is a kind of cosmic hologram, with space, time, and gravity as manifestations of a ...

The nodes in a quantum network don’t necessarily have to be computers; they can also be atomic clocks. The cesium atoms that ...

This discovery strongly indicates that string theory meets the most essential criteria for a quantum theory of gravity. However, the definitive answer to whether string theory is truly the “theory of ...

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.

While the electromagnetic, weak, and strong forces are described by the Standard Model of particle physics, gravity remains an outlier—resisting efforts to be fully explained by quantum theory.

Solving the mystery with string theory To address these inconsistencies, the researchers turned to string theory, one of the leading candidates for a quantum theory of gravity.
