String theory is a broad and varied subject that attempts to address a number of deep questions of fundamental physics. String theory has contributed a number of advances to mathematical physics, which have been applied to a variety of problems in black hole physics, early universe cosmology, nuclear physics, and condensed matter physics, and ...
String vibrations. In physics, a string is a physical entity postulated in string theory and related subjects. Unlike elementary particles, which are zero-dimensional or point-like by definition, strings are one-dimensional extended entities. Researchers often have an interest in string theories because theories in which the fundamental ...
Traditionally, in theoretical physics, the Planck scale is the highest energy scale and all dimensionful parameters are measured in terms of the Planck scale. There is a great hierarchy between the weak scale and the Planck scale, and explaining the ratio of strength of weak force and gravity / = is the focus of much of beyond-Standard-Model physics.
This considerably complicates efforts to test string theory because there is an astronomically high number—10 500 or more—of configurations that meet some of the basic requirements to be consistent with our world. Along with the extreme remoteness of the Planck scale, this is the other major reason it is hard to test superstring theory.
String theory is a branch of theoretical physics that attempts to build a theory of quantum gravity using one-dimensional strings rather than zero-dimensional point particles as fundamental building blocks. The name string theory is somewhat of a misnomer since the modern theory also includes higher dimensional objects known as branes
He was the first to give a precise string-theoretic interpretation of the holographic principle in 1995 [9] and the first to introduce the idea of the string theory landscape in 2003. [ 10 ] [ 11 ] Susskind was awarded the 1998 J. J. Sakurai Prize , [ 12 ] the 2018 Oskar Klein Medal , [ 13 ] and the Dirac Medal of the International Centre for ...
In theoretical physics, a dual resonance model arose during the early investigation (1968–1973) of string theory as an S-matrix theory of the strong interaction. Overview [ edit ]
In 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 to be equivalent to a maximally supersymmetric two-dimensional gauge theory , the gauge group of which is U( N ) for a large value of N .
