Quantum gravity tries to combine Einstein’s general theory of relativity with quantum mechanics. Quantum corrections to classical gravity are visualized as loop diagrams, as the one shown here ...

The quantum field theory framework needed some adjustment for Borinsky and Vogtmann to get the right count. For instance, in quantum field theory, two graphs that are mirror images of each other are ...

How do you calculate infinite quantum outcomes? Feynman Diagrams. The equations of quantum field theory allow us to calculate the behaviour of subatomic particles by expressing them as vibrations ...

In other words, the traditional machinery of quantum field theory, involving hundreds of Feynman diagrams worth thousands of mathematical terms, was obfuscating something much simpler.

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.

Quantum field theory marries the ideas of other quantum theories to depict all particles as “excitations” that arise in underlying fields. The British physicist Paul Dirac started the ball ...
