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.

Physicists claim they may have found a long-awaited explanation for dark energy, the mysterious force that's driving the accelerated expansion of the universe, a new preprint study hints. Their ...

String theory attempts to unify all forces and particles in the universe using vibrating strings. It aims to explain the Standard Model of particle physics, which is incomplete. String theory predicts ...

WEST LAFAYETTE, Ind. — A team of Purdue University researchers has been awarded a $1 million W.M. Keck Foundation grant to experimentally test an early prediction originated from string theory: An ...

Quantum theory and general relativity have long described the universe with incompatible languages, one speaking in probabilities and the other in smooth curves of spacetime. A new line of work argues ...
