'''Superstring theory''' is an attempt to explain all of the [[Elementary particle|particles]] and [[fundamental force]]s of nature in one theory by modeling them as vibrations of tiny [[supersymmetry|supersymmetric]] strings. It is considered one of the most promising candidate theories of [[quantum gravity]]. Superstring theory is a shorthand for '''supersymmetric string theory''' because unlike [[bosonic string theory]], it is the version of [[string theory]] that incorporates [[fermions]] and [[supersymmetry]].

== Background ==

The deepest problem in [[theoretical physics]] is harmonizing the theory of [[general relativity]], which describes gravitation and applies to large-scale structures ([[star]]s, [[galaxies]], [[super cluster]]s), with [[quantum mechanics]], which describes the other three [[fundamental forces]] acting on the atomic scale.

The development of a [[quantum field theory]] of a force invariably results in infinite (and therefore useless) probabilities. Physicists have developed mathematical techniques ([[renormalization]]) to eliminate these infinities which work for three of the four fundamental forces – [[Electromagnetic force|electromagnetic]], [[Strong interaction|strong nuclear]] and [[Weak interaction|weak nuclear]] forces - but not for [[gravity]]. The development of a [[quantum theory of gravity]] must therefore come about by different means than those used for the other forces.

hi  chris sedb this is is the super string theory it is like this one thingy were these dudes put like time in a flashlight and reversed time ....
