a subatomic particle thought of as propagating the action of gravitational force
Though first found in science fiction, it is a theorized particle in physics. In SF typically portrayed as used in propulsion systems.
The engine room of the Inquisitor was provided with two contra-field generators, each of sufficient power to support the vessel when fully loaded…. The basic discovery of the graviton had led Barton to the development of this unique apparatus…. The graviton, be it remembered, was identified by Barton in the laboratory as a close analogy to the magneton, that final element of magnetism whose relation to magnetism is similar to that of the electron to electricity.
Sulaiman bases his theory of gravitation on ‘gravitons’, fine particles ‘at present beyond the range of our perceptions’.
A Wittenberg disrupter tears atoms apart. The free electrons are shunted off into accumulators, where we get power for lighting, cooking, heating and so forth. The protons go into the proton analyzer, where the gravitons are ripped out of them and stored in a special type of spherical field. When we want to move the ship, the gravitons are released. They spread through the ship and everything in the ship. The natural place for a graviton is a proton. The gravitons rush for the protons—which are already saturated with 1846 gravitons. Gravitons are unable to remain free in three-dimensional space. They escape along the time line, into the past.
My luck with a command netted a few puzzles—the peculiar relationships of gravitons to chronons for one, which, of course, was cracked, but only after a thousand years of concerted effort from the entire Third Level Corps.
The sphere was carrying a motor generator creating gravitons, which was fueled by a fission metal which was also its warhead. It manufactured gravitons so fast that its artificial gravity was by now nearly equal to a big planet.
We toggled our pod nacelles, the graviton fields eased us on to the ground, and we were back home, all safe and sound.
A lot of those photos show what’s maybe a graviton generator, maybe not.
For lesser tasks he had the whole spectrum of photons at his disposal, too—radio, heat, visible light, gamma rays, X-rays, even gravitons.
On the screen, three violet beams of focused gravitons reached out to the stricken starship.
Kirk pressed the stud on the jury-rigged graviton projector.
