For the last 40 years, a dedicated group of theoretical physicists has been beavering away on an ambitious project to create a quantum theory of gravity and unify the four forces of nature. Using ...

Bootstrapping strings Evidence that string theory could be the sole viable “theory of everything” has emerged in a new theoretical study of particle scattering. (Courtesy: iStock/Anadmist) Striking ...

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 ...

Recent theoretical advances continue to uncover profound interconnections between string theory and disparate areas of pure mathematics, notably modular forms, finite groups and vertex operator ...

Scientist from the Cluster of Excellence Mathematics Münster proves mathematical conjecture from string theory String theory is a part of mathematical physics that has led to significant advancements ...

An illustration of two black holes about to merge and emitting copious gravitational waves. And as the numbers of gravitational-wave observations have increased, physicists’ careful modeling is ...

1. Name the German physicist who is widely credited with first studying the general theory of relativity in five dimensions, creating the precursors of some ideas that later appeared in string theory.

String theory strutted onto the scene some 30 years ago as perfection itself, a promise of elegant simplicity that would solve knotty problems in fundamental physics—including the notoriously ...

While the novel theory may never live up to the early hype, its innovative tools have helped scientists for decades, and the best may be yet to come. Credit: background, ESO/Mario Nonino/Piero ...
