{{main|String theory}}
World-sheet description of string theory involves a two-dimensional CFT coupled to dynamical two-dimensional quantum gravity (or supergravity, in case of superstring theory). Consistency of string theory models imposes constraints on the central charge of this CFT, which should be {{nowrap|1=''c'' = 26}} in bosonic string theory and {{nowrap|1=''c'' = 10}} in superstring theory. Coordinates of the spacetime in which string theory lives correspond to bosonic fields of this CFT.
