String theory is a purported theory of everything that physicists hope will one day explain … everything. All the forces, all the particles, all the constants, all the things under a single ...

String theory attempts to unify all forces and particles in the universe using vibrating strings. It aims to explain the Standard Model of particle physics, which is incomplete. String theory predicts ...

Could the universe have hidden dimensions we’ve yet to detect? The idea of extra dimensions has intrigued physicists for over a century, and while there’s no solid evidence to prove their existence, ...

In this video, we explore the relationship between string theory and quantum field theory (QFT). QFT is a mathematical framework that describes nearly all particles and forces in the universe but ...

Most people are perfectly content with three dimensions to carry out daily tasks -- or four if they take time into account. String theorists, on the other hand, think that many more dimensions are ...

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 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 ...
