string theorynoun
A mathematical theory for describing the properties of fundamental particles, which represents the particles as one-dimensional string-like objects, which exist in the normal four dimensions of space-time plus additional dimensions, the total dimensions being ten, eleven, or twenty-six depending on the version of the theory. The properties of fundamental particles in string theory and their manner of interaction with each other depend upon the modes of vibration of the strings{17}. The attractiveness of this theory rests in part on its ability to provide a unified treatment of gravity as well as the three other basic forces of nature, in a manner consistent with quantum mechanics. The great difficulty of doing the calculations required by the theory, however, has thus far (1999) made it impossible to calculate the observable properties, such as the mass, of known particles, such as the electron, proton, mesons, quarks, and neutron; thus there is as yet no experimental verification for the theory. The most popular version of the theory depends on a mathematical property called supersymmetry, and the theory derived form this principle is properly called superstring theory, a term which is often used interchangeably with string theory. See also string{17}.
Wiktionary
string theorynoun
A candidate unified theory of all physical forces and particles; a theory which suggests that subatomic particles are one-dimensional strings rather than zero-dimensional points. It also suggests that space-time can have up to nine dimensions, plus the dimension of time.

string theory
String theory is a theoretical framework in which the point-like particles of particle physics are replaced by one-dimensional objects called strings. It describes how these strings propagate through space and interact with each other, potentially reconciling quantum physics and general relativity. It also proposes the existence of more than the four known dimensions.

String theory
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. In string theory, the different types of observed elementary particles arise from the different quantum states of these strings. In addition to the types of particles postulated by the standard model of particle physics, string theory naturally incorporates gravity, and is therefore a candidate for a theory of everything, a self-contained mathematical model that describes all fundamental forces and forms of matter. Aside from this hypothesized role in particle physics, string theory is now widely used as a theoretical tool in physics, and it has shed light on many aspects of quantum field theory and quantum gravity. The earliest version of string theory, called bosonic string theory, incorporated only the class of particles known as bosons, although this theory developed into superstring theory, which posits that a connection exists between bosons and the class of particles called fermions. String theory requires the existence of extra spatial dimensions for its mathematical consistency. In realistic physical models constructed from string theory, these extra dimensions are typically compactified to extremely small scales.
