WebAug 10, 2007 · The numbers may not jibe, but physicists have a hunch about gravity's unseen gremlins: Tiny, massless particles called gravitons that emanate gravitational fields. Each hypothetical bit tugs on... 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.

Einstein described gravity as equivalent to curves in space and time, but physicists have long searched for a theory of gravitons, its putative … WebYes, gravitons (assuming they exist, that is, assuming that gravity is a quantum field theory with a low-energy perturbative limit, where speaking of gravitons makes sense) have energy. Yes, a body loses energy while emitting gravitons. Very little energy, to be sure. A body may lose energy by emitting gravitons when it is accelerating.
