string theory
A theory of elementary particles based on the idea that the fundamental entities are not pointlike particles but finite lines, known as strings, or closed loops formed by strings (see also cosmic strings). Incorporating the concept of strings into supersymmetry has led to superstring theory, in which all the fundamental forces are unified at the Planck time using a multidimensional framework called a superstring; this is still a highly speculative theory.Collins Dictionary of Astronomy © Market House Books Ltd, 2006
string theory
The belief that all physical matter is made up of vibrating elements called "strings." Officially known as "superstring theory," it differs from traditional physics, in which all matter is made up of ball-like particles.Copyright © 1981-2025 by The Computer Language Company Inc.
