String theory—the idea that particles are not point-like, but instead one-dimensional strings—is a popular theoretical framework that attempts to combine general relativity and quantum field theory ...

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 ...

It's one of the most brilliant, controversial and unproven ideas in all of physics: string theory. At the heart of string theory is the thread of an idea that's run through physics for centuries, that ...
