Scientists are on the trail of a mysterious five-particle structure that could challenge one of the biggest theories in physics: string theory. This rare particle—never seen before and predicted not ...

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 ...

On a quiet pandemic afternoon in 2021, Zhiyuan Wang, then a graduate student at Rice University, was alleviating his boredom by working on a weird mathematical problem. After he found an exotic ...

String theory began over 50 years ago as a way to understand the strong nuclear force. Since then, it’s grown to become a theory of everything, capable of explaining the nature of every particle, ...
