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

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

Physicists searching for a better understanding of quantum gravity stumbled upon something unexpected: the defining ...

Quantum field theory (QFT) realises particles as excitations of underlying fields that permeate spacetime. By quantising classical gauge and matter fields, QFT unifies quantum mechanics with special ...

String field theory is a second-quantised framework that recasts the perturbative dynamics of strings in terms of field-theoretic variables on the space of string configurations. By organising ...

If you could take an apple and break it into smaller and smaller parts, you would find molecules, then atoms, followed by subatomic particles like protons and the quarks and gluons that make them up.

Physicists may have uncovered a surprising new clue that string theory—the idea that the universe is built from unimaginably tiny vibrating strings—could be more than just a mathematical fantasy.

Tenets of quantum mechanics and special relativity, among other theoretical ideas, lead inexorably to string theory.

In 1980, Stephen Hawking gave his first lecture as Lucasian Professor at the University of Cambridge. The lecture was called “Is the end in sight for theoretical physics?” Hawking, who later became my ...

Scientists are on the trail of a mysterious five-particle structure that could challenge one of the biggest theories in physics: string theory. This rare particle—never seen before and predicted not ...
