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. The three other known forces of nature are mediated by elementary particles: See more Unambiguous detection of individual gravitons, though not prohibited by any fundamental law, is impossible with any physically reasonable detector. The reason is the … See more • Gravitino • Dual graviton • Gravitoelectromagnetism • Planck mass • Static forces and virtual-particle exchange See more The term graviton was originally coined in 1934 by Soviet physicists Dmitrii Blokhintsev [ru; de] and F.M. Gal'perin. A mediation of the gravitational interaction by particles was … See more While gravitons are presumed to be massless, they would still carry energy, as does any other quantum particle. Photon energy and gluon energy are also carried by massless particles. … See more Most theories containing gravitons suffer from severe problems.
