In this video, we explore the relationship between string theory and quantum field theory (QFT). QFT is a mathematical ...

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 ...

The existence of parallel universes has long been one of the biggest mysteries of the universe. Now, scientists believe they have found a way to some day detect hidden dimensions. Physicists think ...

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 ...

Why does string theory require 10 or 11 spacetime dimensions? The answer at a technical level is well-known, but it's hard to bring it down to earth. By reading economics blogs by people who check out ...

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 ...
