There’s a mystery lying at the heart of physics. Two long-held theories—general relativity and the standard model of particle physics—do an incredible job at explaining the universal and the subatomic ...

Columnist Natalie Wolchover examines the latest developments in the “forever war” over whether string theory can describe the ...

Scientists seeking the secrets of the universe would like to make a model that shows how all of nature’s forces and particles fit together. It would be nice to do it with Legos. But perhaps a better ...

Gauge theory and string theory represent two foundational pillars in contemporary theoretical physics, offering profound insights into the nature of fundamental interactions and the structure of the ...

String theory—the idea that particles are not point-like, but instead one-dimensional strings—is a popular theoretical framework that attempts to combine general relativity and quantum field theory ...
