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 ...

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 ...

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 ...

The first step toward quantum gravity, the "holy grail of physics," may be hiding in a quantum recipe to cook up black holes. That's the suggestion of new research that adds quantum corrections to ...

In this video, we explore the relationship between string theory and quantum field theory (QFT). QFT is a mathematical ...

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 Physical Review Letters study places constraints on the ER = EPR conjecture, showing that under the authors' ...

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