Britannica Editors History Britannica AI Ask Anything Table of Contents Table of Contents Ask Anything graviton , postulated quantum that is thought to be the carrier of the gravitational field . It is analogous to the well-established photon of the electromagnetic field . Gravitons, like photons, would be massless, electrically uncharged particles traveling at the speed of light . Since gravitons would apparently be identical to their antiparticles, the notion of antigravity is questionable. Gravitons have not been directly observed; as of 2016, observations of weak lensing of distant galaxies have placed the tightest bound on the graviton’s mass as being less than 6 × 10 −32 electron volts .
