| graviton | has spin 2 |  |
| carries the force gravity |  |
| has definition A massless spin-2 particle which is the hypothetical quantum of the gravitational field. It mediates the force of gravity in a similar way to that in which the spin-1 gauge bosons (i.e. the photon, W±, Z0, and gluons) mediate the other forces. |  |
| has definition A hypothetical elementary particle associated with the gravitational interaction. It is a stable particle with zero rest mass, zero charge, and a spin of ± 2, and travels with the speed of light. |  |
| has definition Smallest bundle of the gravitational force field; messenger particle for the gravitational force. |  |
| has definition The hypothetical quantum particle of the gravitational field. It could also be thought of as a quantized element of space-time curvature. |  |
| has definition A quantum of gravitational radiation. |  |
| has definition The quanta thought to convey gravitational force; analogous to the photons, gluons, and intermediate vector bosons of electromagnetism and the strong and weak nuclear forces. Predicted by quantum theory of gravity, gravitons have not yet been detected. |  |
