The history of string theory spans several decades of intense research including two superstring revolutions. Through the combined efforts of many researchers...

In physics, string theory is a theoretical framework in which the point-like particles of particle physics are replaced by one-dimensional objects called...

'Superstring theory' is a shorthand for supersymmetric string theory because unlike bosonic string theory, it is the version of string theory that accounts...

type II string theory is a unified term that includes both type IIA strings and type IIB strings theories. Type II string theory accounts for two of the five...

Bosonic string theory is the original version of string theory, developed in the late 1960s and named after Satyendra Nath Bose. It is so called because...

In string theory, a heterotic string is a closed string (or loop) which is a hybrid ('heterotic') of a superstring and a bosonic string. There are two...

In string theory, the string theory landscape (or landscape of vacua) is the collection of possible false vacua, together comprising a collective "landscape"...

String field theory (SFT) is a formalism in string theory in which the dynamics of relativistic strings is reformulated in the language of quantum field...

In theoretical physics, type I string theory is one of five consistent supersymmetric string theories in ten dimensions. It is the only one whose strings...

In physics, a string is a physical entity postulated in string theory and related subjects. Unlike elementary particles, which are zero-dimensional or...

nevertheless equivalent when employed as extra dimensions of string theory. Early cases of mirror symmetry were discovered by physicists. Mathematicians...

E8 theory, noncommutative geometry, and causal fermion systems have not demonstrated any level of mathematical consistency. History of string theory Wolchover...

D0-branes in Type IIA string theory. In geometry, it is often useful to introduce coordinates. For example, in order to study the geometry of the Euclidean plane...

In theoretical physics, topological string theory is a version of string theory. Topological string theory appeared in papers by theoretical physicists...

blocks of matter and light. Under string theory, strings are bundles of energy vibrating in complex ways in both the three familiar dimensions of space...

dictionary. In string theory and related theories (such as supergravity theories), a brane is a physical object that generalizes the notion of a zero-dimensional...

theoretical physics, F-theory is a branch of string theory developed by Iranian-American physicist Cumrun Vafa. The new vacua described by F-theory were discovered...

Eleven-dimensional supergravity Theories studied in the branch of quantum field theory known as string theory. These theories are without supersymmetry. Polyakov...

physics, matrix string theory is a set of equations that describe superstring theory in a non-perturbative framework. Type IIA string theory can be shown...

Twistor string theory is an equivalence between N = 4 supersymmetric Yang–Mills theory and the perturbative topological B model string theory in twistor...

A theory of everything (TOE), final theory, ultimate theory, unified field theory, or master theory is a hypothetical, singular, all-encompassing, coherent...

within the framework of field theory. But in the guise of string theory, S-matrix theory is still a popular approach to the problem of quantum gravity. The...

In string theory, a worldsheet is a two-dimensional manifold which describes the embedding of a string in spacetime. The term was coined by Leonard Susskind...

non-critical string theory describes the relativistic string without enforcing the critical dimension. Although this allows the construction of a string theory in...

History of Time speculated that this theory could be the Theory of Everything. However, in later years this was abandoned in favour of string theory....
