Explainer: String theory - The Conversation
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. On distance scales larger than the string scale, a string looks just like an ordinary particle, with its mass, charge, and other properties determined by the vibrational state of the string. In string theory, one of the many vibrational state… The five consistent superstring theories are: The type I string has one supersymmetry in the ten-dimensional sense (16 supercharges ). This theory is special in the... The type II string theories have two supersymmetries in the ten-dimensional sense (32 supercharges). There are actually... The ... See more Superstring theory is an attempt to explain all of the particles and fundamental forces of nature in one theory by modeling them as vibrations of tiny supersymmetric strings. 'Superstring theory' is a shorthand for supersymmetric … See more Superstring theory is based on supersymmetry. No supersymmetric particles have been discovered and recent research at the Large Hadron Collider (LHC) and Tevatron has excluded some of the ranges. For instance, the mass constraint of the See more Theoretical physicists were troubled by the existence of five separate superstring theories. A possible solution for this dilemma was suggested at the beginning of what is called the second superstring revolution in the 1990s, which suggests that the five string … See more The deepest problem in theoretical physics is harmonizing the theory of general relativity, which describes gravitation and applies to large-scale structures (stars, galaxies See more Investigating how a string theory may include fermions in its spectrum led to the invention of supersymmetry (in the West ) in 1971, a mathematical transformation between bosons and fermions.
