'''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 (contracted; show full)can be investigated directly in any experiment (which must show different results in 1, 2, or 2+1 dimensions to a human scientist). This, in turn, raises the question of whether models that rely on such abstract modeling (and potentially impossibly huge experimental apparatus) can be considered 'scientific.' Six-dimensional [[Calabi-Yau]] shapes can account for the additional dimensions required by superstring theory.

Superstring theory is not the first theory to propose extra spatial dimensions
;, the [[Kaluza-Klein theory]] did already. Modern string theory relies on the mathematics of folds, knots, and [[topology]], which was largely developed after Kaluza and Klein, and has made physical theories relying on extra dimensions much more credible.
