1942Chem. Abstr. XXXVI. 6074 Plane waves of a particle with spin 2 (graviton). 1960New Scientist 2 June 1433/2 To produce gravitons, one would need rapidly varying gravitational fields. Such fields are familiar in astronomy and accompany double stars. However..it will be a very long time before (astronomical) gravitons can be detected even if these exist. 1971Sci. Amer. May 22/2 This fact, together with the small value of the gravitational constant, means that only one graviton (the quantum of gravitational radiation) would be emitted by an atom or a molecule for every 1043 photons (light quanta) emitted. |
