Gravitons are predicted by quantum gravity theories, not by general relativity
In [[Quantum gravity|quantum gravity]], the '''graviton''' is a hypothetical particle which mediates the [[Gravitation|gravitational interaction]]. If it exists, the graviton is expected to be a massless, weakly interacting, spin-2 gauge boson.<ref>Feynman, Morinigo, Wagner & Hatfield. <i>Feynman lectures on gravitation.</i> (1995).</ref>
