Here’s what you’ll learn when you read this story: String theory—the idea that particles are not point-like, but instead one-dimensional strings—is a popular theoretical framework that attempts to ...

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 ...
