Single Idea 21177

[catalogued under 27. Natural Reality / B. Modern Physics / 5. Unified Models / b. String theory]

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


New Scientist writers (Why the Universe Exists [2017], 09)

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.
