High Energy Gravitons

Abstract

Considerable efforts have been devoted to the detection of gravitational waves, the counterpart of electromagnetic waves, without success. High density systems of matter should emit gravitons, counterpart of photons, and particularly at high energies they ought to be detectable and unambiguously identifieble. Dark matter is surmised to predominate in the known universe (90-99 %). In general, matter (dark or visible) far beyond nuclear densities should emit gravitons at very high energies. There are no known bounds for densities of matter and compressibilities, dark matter most probably included It is believed that the gravitational parameter enjoins those of the other known forces in the energy range of 1016 to 1018 GeV. There is a considerable energy range where gravitation and its effects differ from the other fields and may be singled out. Gravitons in the range of 1021 eV can be shown to originate in physical systems within de Planck mass and length horizons. Due to the dominance of dark over visible matter, high energy gravitons (HEG) fluxes should be dominated by the former and yield information about its distribution. It appears that a dedicated HEG Moon observatory would be ideally suited for the detection of HEGs and provide evidence for dark matter.
