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 ...

From Quanta Magazine (find original story here). String theory was devised as a way to unite the laws of quantum mechanics with those of gravity, with the goal of creating the vaunted “theory of ...

One of the strangest ideas about the nature of the universe could be one of the most important. Do long, thin, and incredibly dense strands of matter called cosmic strings wind their way throughout ...

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 ...
