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 framework that describes nearly all particles and forces in the universe but ...

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

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 ...

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 ...

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.

A new theoretical study suggests that the mysterious force driving the accelerated expansion of the universe—known as dark energy—may actually be rooted in a deeply quantum structure of space-time.

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 ...

Add Yahoo as a preferred source to see more of our stories on Google. String theory attempts to unify general relativity and quantum theory. Popular in the 1990s, string theory fell out of favor as it ...
