In physics, string theory is a theoretical framework in which the point-like particles of particle physics are replaced by one-dimensional objects called strings. String theory describes how these strings propagate through space and interact with each other.
String theory is a mathematical framework that aims to unify quantum mechanics and general relativity by modeling subatomic particles as vibrating strings. Learn about its origins, predictions, difficulties, and prospects from Britannica's experts.
Learn about string theory, a candidate for a unified theory of the four fundamental forces of nature. Explore the concepts, types, problems, and applications of string theory with examples and exercises.
String theory proposes that everything is made of tiny strings whose vibrations produce subatomic particles. It also requires extra dimensions of space that are curled up too small to notice. Learn more about the challenges and possibilities of this radical framework.
29 de ago. de 2019 · String theory is the idea that everything in the universe is made of vibrating strings in multiple dimensions. Learn how string theory emerged, what it promises and why it is controversial.
Brian Greene explains the basic idea of String Theory in under 3 minutes. Thirty-five years ago string theory took physics by storm, promising the coveted unified theory of nature’s forces...
Learn the basics of string theory, a unified approach to quantum mechanics and gravity, from MIT Professor Hong Liu. Explore the concepts, questions, and applications of string theory, such as spacetime dimension, AdS/CFT duality, and more.
