String theory standard model
WebThe standard model describes quite accurately physics near the electroweak symmetry breaking scale (246 GeV). But the standard model is only a low energy approximation to a more fundamental theory. The standard model cannot be valid at energies above the Planck scale (~10 19 GeV), where gravity can no longer be ignored. WebFeb 26, 2001 · Ill refer to this fundamental theory as string theory without distinguishing various forms. String theory is formulated in 10 dimensions and has other properties that …

WebSep 15, 2016 · This effect could be one answer to a big problem string theory was supposed to solve. As Gross put it: “What picks out this particular theory” — the Standard Model — from the “plethora of infinite possibilities?” Silverstein thinks the selection effect is actually a good argument for string theory.

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.
