Modern physics explains nearly every particle and force in nature—except gravity. This video explores how string theory and M ...

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, ...

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 ...

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 ...

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 ...

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 ...

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, ...

The idea of String Theory is that our Universe came from a higher-dimensional, more symmetric, more complex state with an enormous number of degrees of freedom. In order for String Theory to be solved ...

Add Yahoo as a preferred source to see more of our stories on Google. Scientists seeking the secrets of the universe would like to make a model that shows how all of nature’s forces and particles fit ...

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 ...
