superstring theory

Show Summary Details

Quick Reference

An example of a general class of theories of high-energy physics known as string theories. In string theories, the fundamental objects are not point-like objects (particles) but one-dimensional objects known as strings. Superstrings are strings which also have the property of supersymmetry (i.e. every particle which is a boson has a partner which is a fermion). The superstring theory tries to describe all classes of observed elementary particle in terms of properties of such strings. The theory is entirely speculative, but may have some implications for the physics of the very early Universe.
