String theory is one of the most ambitious ideas in modern physics, aiming to unite all forces of nature into one framework.

String theory proposes that the fundamental constituents of the universe are one-dimensional “strings” rather than point-like particles. What we perceive as particles are actually vibrations in loops ...

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 ...

One possibility to explain the constants of nature is that there’s more than one universe. That we live in a multiverse, with ...

String theory, conceptualized more than 50 years ago as a framework to explain the formation of matter, remains elusive as a ...

A new theoretical study suggests that the mysterious force driving the accelerated expansion of the universe—known as dark energy—may actually be rooted in a deeply quantum structure of space-time.
