WebJan 15, 2010 · We review past and current studies of possible long-distance, low-frequency deviations from Maxwell electrodynamics and Einstein gravity. Both have passed through three phases: (1) Testing the inverse-square laws of Newton and Coulomb, (2) Seeking a nonzero value for the rest mass of photon or graviton, and (3) Considering more … WebDec 10, 2008 · Search first posts only.

WebSince gravity is an inverse square force of apparently infinite range, it can be implied that the rest mass of the graviton is zero. Forces are transmitted by bosons including the photon for the electromagnetic force and the W and Z bosons for the weak interaction. Associated with the color force, the gluons are the exchange particles. WebA single graviton of a given angular frequency ! cannot be con ned within a region with linear dimension smaller than the reduced wavelength (c=!). Therefore the energy density of a single graviton of this frequency is at most equal to the energy of the graviton divided by the cube of its reduced wave-length, namely E s = ( h!4=c3): (3)
WebMar 4, 2014 · (Phys.org) —Among the four fundamental forces of nature, only gravity has not had a basic unit, or quanta, detected. Physicists expect that gravitational force is transmitted by an elementary... WebDec 28, 2015 · If gravity were just another field, then the existence of a photon state in one spacetime point would create excited graviton states around it. This is the usual formulation of quantum field theory on a preordained background. Unfortunately gravity doesn't quantize this way.
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.
