Researchers in Japan have developed what may be the first string-theory model with a natural mechanism for explaining why our universe would seem to exist in three spatial dimensions if it actually ...

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 ...

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 ...

Experimental physicists study the strong force; string theorists try to calculate its effects. Together, they are finding common ground, where string theory can be applied to the physics of ...

String theory has come under fire in recent years. Promises have been made that have not been lived up to. Theoretical physicists have now for the first time used string theory to describe a physical ...

Theoretical physicists use machine-learning algorithms to speed up difficult calculations and eliminate untenable theories—but could they transform what it means to make discoveries? Theoretical ...
