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.
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.
7 de jun. de 2021 · Learn how string theory combines quantum mechanics and general relativity to describe the smallest building blocks of matter and the forces that act on them. MasterClass offers online courses on science and tech topics, including string theory.
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.
25 de abr. de 2022 · String theory is a theoretical framework to address the shortcomings of Einstein's theory of general relativity and quantum physics - two primary tools for understanding modern physics. String theory is often referred to as the theory of everything - a just identification given its ability to bridge the gap between gravity and ...
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.
