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.

WebNov 9, 2024 · In theories that try to provide a quantum description of gravity, the graviton mediates the gravitational force between massive objects. It can be thought of as a gravitational version of the photon, which mediates the electromagnetic force between charged objects. WebA graviton is a gauge boson. It is a local quantized excitation of a Lorentz invariant and gauge invariant quantum field in (3+1) dimensions. The gauge is SO (1,3). In a gauge QFT, the gauge boson couples to the source particle and mediates the interaction between 2 such source particles.
