Abstract
There are five anomaly-free, perturbative superstring theories [164] . It is now widely believed that these theories represent special points in the moduli space of a more fundamental, non-perturbative theory known as M-theory [376], and so no particular string theory is necessarily more fundamental since they are all related by duality symmetries (for a review see, e.g., Ref. [321]). Moreover, another point of this moduli space corresponds to eleven-dimensional supergravity. This represents the low-energy limit of M-theory [337, 376] .
