In 1951, physicist Julian Schwinger theorized that by applying a uniform electrical field to a vacuum, electron-positron ...

"A quantum theory of gravity is needed to understand what kind of phenomena there are in cases where there's a gravitational field and high energies," says Partanen.

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.

Gravity as Quantum Entropy Gravity, traditionally seen as the curvature of spacetime caused by massive objects, might instead arise from entropy—a measure of disorder. This new theory treats ...

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.

Why Gravity Resists Unification The Standard Model is built on a framework called quantum field theory. This theory merges classical field theory, quantum mechanics, and special relativity.

"If this turns out to lead to a complete quantum field theory of gravity, then eventually it will give answers to the very difficult problems of understanding singularities in black holes and the ...

The theory also builds upon well-established principles in quantum field theory. It borrows from the Dirac-Kähler formalism, which has gained traction in lattice gauge theory and network theory.

Researchers have developed a new quantum theory of gravity which describes gravity in a way that's compatible with the Standard Model of particle physics, opening the door to an improved ...
