Full Idea

String theory works as a quantum theory of gravity because string vibrations can describe gravitons, the hypothetical carriers of the gravitational force.

Gist of Idea

String theory offers a quantum theory of gravity, by describing the graviton

A Reaction

Presumably the main aim of a quantum theory of gravity is to include gravitons within particle theory. This idea has to be a main attraction of string theory. Compare Idea 21166.
