What is string theory? In this video, we explain string theory in simple words — from the magical garden analogy (invisible vibrating strings creating everything you see) to why quantum mechanics and general relativity don't get along, how string theory could be the "theory of everything," and why it requires 9, 10, or even 25 dimensions of space. Learn about the four fundamental forces, why gravity is the odd one out, and how the Large Hadron Collider might one day prove string theory.
Whether you're a physics student, a science fiction fan, or just curious about what the universe is really made of, this beginner-friendly animated explainer covers the basics of one of physics' most ambitious ideas.
