WebAug 18, 2024 · These gravitons are massless, which means they can, in theory, travel an infinite distance, just as photons (the carriers of the electromagnetic force) let us see to the edges of the universe. ... Einstein’s general relativity seems to work so well. Why do we need to modify gravity? After the Big Bang, the universe expanded and cooled down. ... 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. It is unclear which variables might determine graviton energy, the amount of energy carried by a single graviton. Alternatively, if … 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 Unambiguous detection of individual gravitons, though not prohibited by any fundamental law, is impossible with any physically reasonable detector. The reason is the extremely low cross section for the interaction of gravitons with matter. For example, a detector … See more • Gravitino • Dual graviton • Gravitoelectromagnetism • Planck mass • Static forces and virtual-particle exchange 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 … 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 anticipated by Pierre-Simon Laplace. Just like Newton's anticipation of photons See more Most theories containing gravitons suffer from severe problems. Attempts to extend the Standard Model or other quantum field theories by adding gravitons run into serious theoretical difficulties at energies close to or above the Planck scale.
