The universe feels three-dimensional — but some of the deepest physics suggests reality may have 11 dimensions hidden from our senses. This idea comes from theories like string theory and M-theory, ...

Modern physics explains nearly every particle and force in nature—except gravity. This video explores how string theory and M-theory attempt to solve that problem by proposing that the universe is ...

Scientists seeking the secrets of the universe would like to make a model that shows how all of nature's forces and particles fit together. It would be nice to do it with Legos. But perhaps a better ...

String theory and its extensions propose that the elementary constituents of matter are not point particles but one-dimensional strings whose vibrational modes manifest as observed particles and ...

String theory found its origins in an attempt to understand the nascent experiments revealing the strong nuclear force. Eventually another theory, one based on particles called quarks and force ...

At the turn of the century, it sounded as if string theory could give us big answers about the universe. Well… has it? String theorists, this one may be for you. The theorized object warps spacetime ...

The original version of this story appeared in Quanta Magazine. String theory captured the hearts and minds of many physicists decades ago because of a beautiful simplicity. Zoom in far enough on a ...

WHEN Joseph Conlon was an undergraduate in the early 2000s, he avoided popular science accounts of string theory because he wanted to engage with it on a technical level, without preconceptions. It ...

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, ...

Scientists seeking the secrets of the universe would like to make a model that shows how all of nature’s forces and particles fit together. It would be nice to do it with Legos. But perhaps a better ...

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 ...
