String Theory Meets Loop Quantum Gravity Quanta Magazine
A graviton in perturbative string theory is a closed string in a very particular low-energy vibrational state. The scattering of gravitons in string theory can also be computed from the correlation functions in conformal field theory, as dictated by the AdS/CFT correspondence, or from matrix theory. [citation needed] See more 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 … See more While gravitons are presumed to be massless, they would still carry energy, as does any other quantum particle. Photon energy See more Most theories containing gravitons suffer from severe problems. Attempts to extend the Standard Model or other quantum field theories by adding … See more It is hypothesized that gravitational interactions are mediated by an as yet undiscovered elementary particle, dubbed the graviton. The … See more The term graviton was originally coined in 1934 by Soviet physicists Dmitrii Blokhintsev [ru; de] and F.M. Gal'perin.
