Quantum field theory says true nothingness doesn’t exist; even a vacuum teems with energy fields that help create matter and ...

Gravity is one of four fundamental interactions. The most precise description of this force is still provided by Einstein's General Theory of Relativity, published in 1915, an entirely classical ...

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 ...

An international team of researchers has found a simple relationship between the rates of energy and information transmission across an interface connecting two quantum field theories. An ...

University of Chicago physicist Clay Córdova has been named a recipient of the 2026 New Horizons in Physics Prize for his work in quantum field theory. He was recognized alongside three colleagues: ...

A rewrite of quantum mechanics that includes the force of gravity could finally achieve one of physicists’ biggest goals and ...

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.

Does anyone understand quantum theory? The legendary Richard Feynman suggested that if you think you do, you haven’t understood it at all. But quantum theory is our best description of the microscopic ...

A new study just added an interesting twist to the complicated history of the physics theory.
