Scientists have long sought evidence to refute string theory, but a new test seeks to disprove key aspects with help from the Large Hadron Collider.

Recent decades have witnessed remarkable progress in establishing rigorous mathematical frameworks for quantum field theory (QFT), conformal field theory (CFT), quantum gravity and string theory ...

It promises a coherent description of the Universe at both the quantum and cosmological scales. However, string theory requires the existence of additional spatial dimensions beyond the three we know.

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.

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.

When mathematicians revived ignored mathematical structures, they found that overlooked particles, called "neglectons," could ...

This doesn’t suddenly mean that we’ve found the ever-elusive “theory of everything”—a concept that unifies all physics both classical and quantum.

The prevailing assumption has been that Einstein's theory of gravity must be modified, or 'quantized', in order to fit within quantum theory. This is the approach of two leading candidates for a ...

A novel theory of "wavy space-time" suggests the division between our best descriptions of the universe on its smallest and largest scales may be because gravity does not play by quantum rules.

String theory, conceptualized more than 50 years ago as a framework to explain the formation of matter, remains elusive as a "provable" phenomenon. But a team of physicists has now taken a ...
