superstring theory

subject fact

superstring theory has definition String theory that incorporates supersymmetry. has source: Greene, B. 1999 The Elegant Universe, W.W. Norton and Co., New York, 2001-09-27 09:33:59.0
has definition A new type of theory in physics that unifies all the forces of nature, including the gravitational force, and that may be capable of explaining all of the fundamental laws and particles of nature. In superstring theories, the basic constituent of matter is a 1-dimensional structure, called a string, rather than a point-particle structure. According to superstring theory, space has more than 3 dimensions. has source: Lightman, A., Brawer, R. 1990 The Lives and Worlds of Modern Cosmologists, Harvard University Press, 2001-09-27 09:33:59.0
has definition A proposal for the ultimate laws of nature, a "theory of everything," stemming primarily from discoveries in the mid 1980's. The fundamental entity in this theory is an ultramicroscopic string-like object, with a length of typically 10^-33 centimeters and effectively zero thickness. At present our understanding of string theory is very limited. The simplest predictions of superstring theory concern processes at the Planck energy, and so far very little is known about the consequences of string theory at lower energies. has source: Guth, A.H. 1997 The Inflationary Universe, Addison-Wesley, 2001-09-27 09:33:59.0

Kinds of superstring theory :

heterotic string theory (2 kinds, 8 facts) - Gross's version of string theory in which space-times of different dimensions are associated with the same closed loop.
M-Theory (2 facts) - Theory emerging from the second superstring revolution that unites the previous five superstring theories within a single overarching framework. M-theory appears to be a theory involving eleven spacetime dimensions, although many of its detailed properties have yet to be understood.
type I string theory (2 facts) - One of the five superstring theories; involves both open and closed strings.
type IIA string theory (2 facts) - One of the five superstring theories; involves closed strings with left-right symmetric vibrational patterns.
type IIB string theory (2 facts) - One of the five superstring theories; involves closed strings with left-right asymmetric vibrational patterns.
