WebSep 24, 2024 · Gravitons have spin 2, photons spin 1. Since both are massless they have nevertheless both only two polarization-degrees of freedom, labelled by helicity, being (gravitons) or (photons) respectively. The helicity is the projection of total angular momentum to the direction of the momentum of the graviton or photon. Sep 23, 2024. … In theories of quantum gravity, the graviton is the hypothetical quantum of gravity, an elementary particle that mediates the force of gravitational interaction. There is no complete quantum field theory of gravitons due to an outstanding mathematical problem with renormalization in general relativity. In string … See more It is hypothesized that gravitational interactions are mediated by an as yet undiscovered elementary particle, dubbed the graviton.
