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.
Jun 7, 2021 · String theory is a theoretical framework that unifies quantum mechanics and general relativity. Learn how string theory works, what it implies for the nature of space and time, and why it remains a controversial topic in physics.
Aug 2, 2024 · String theory is a theoretical framework that aims to unify quantum mechanics and general relativity by modeling subatomic particles as vibrating strings. Learn about its origins, predictions, difficulties, and dimensions 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 this radical idea and its challenges.
May 18, 2023 · String theory is a collection of ideas in theoretical physics in which the fundamental building-blocks of nature are not particles (such as the point-like electron) but instead...
Apr 15, 2009 · Learn what string theory is, how it explains the fundamental particles and forces of nature, and why it is so hard to test. Explore the ideas of extra dimensions, multiple universes, twistor theory, inflation and more.
String theory is a candidate for a unified theory of the four fundamental forces of nature, based on the vibrations of one-dimensional strings. Learn about the history, types, problems, and applications of string theory in this comprehensive article.
