A unified theory of everything has long eluded scientists due to gravity being irreconcilable with the three other fundamental forces (electromagnetic, weak, and strong) described using quantum ...

Without such a theory, physicists cannot reconcile our two most powerful theories, quantum field theory and general relativity. Quantum theory describes the world of the very small—tiny ...

The biggest challenge in theoretical physics for more than a century has been to develop a unified theory that combines gravity and the other three fundamental forces of the Universe: the strong and ...

Physicist John Cardy and his colleague just won the 2024 Breakthrough Prize in Fundamental Physics. We spoke with Cardy about conformal field theory, 2D black holes and coffee filters ...

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.

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 ...
