String theory - wikipedia

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. String theory describes how these strings propagate through space and interact with each other. On distance scales larger than the string scale, a string … See more Overview In the 20th century, two theoretical frameworks emerged for formulating the laws of physics. The first is Albert Einstein's general theory of relativity, a theory that explains the force of See more One approach to formulating string theory and studying its properties is provided by the anti-de Sitter/conformal field theory (AdS/CFT) correspondence. This is a theoretical result which implies that string theory is in some cases equivalent to a quantum field … See more In addition to influencing research in theoretical physics, string theory has stimulated a number of major developments in pure mathematics. Like many developing … See more Prior to 1995, theorists believed that there were five consistent versions of superstring theory (type I, type IIA, type IIB, and two versions of heterotic string theory).

WebJan 12, 2016 · In loop quantum gravity, or LQG, space-time is a network. The smooth background of Einstein’s theory of gravity is replaced by nodes and links to which quantum properties are assigned. In this way, space is built up of discrete chunks. LQG is in large part a study of these chunks. This approach has long been thought incompatible with string ...

WebString theory represents an outgrowth of S-matrix theory, [1] a research program begun by Werner Heisenberg in 1943 [2] following John Archibald Wheeler 's 1937 introduction of the S-matrix. [3] Many prominent theorists picked up and advocated S-matrix theory, starting in the late 1950s and throughout the 1960s.

WebName Initially, the term theory of everything was used with an ironic reference to various overgeneralized theories. For example, a grandfather of Ijon Tichy – a character from a cycle of Stanisław Lem's science fiction stories of the 1960s – was known to work on the " General Theory of Everything ".
