WebFeb 28, 2005 · At a loss to explain the stunning discovery, cosmologists blamed it on dark energy, a newly coined term to describe the mysterious antigravity force apparently pushing galaxies outward. This... WebDark matter does cluster, collapsing gravitationally into clumps, but those clumps are much larger and more diffuse than the clumps of ordinary matter we're so familiar with. Why not? The answer seems to be that dark matter has few ways to dissipate energy.

WebJul 1, 2016 · We consider the possibility that the massive graviton is a viable candidate for dark matter in the context of bimetric gravity. We first derive the energy-momentum tensor of the massive graviton and show that it indeed behaves as that of dark matter fluid. We then discuss a production mechanism and the present abundance of massive gravitons … Webgravitons, when the massive graviton is generated, the massless graviton is also generated. Massless gravitons would then be observed as a gravitational wave back-ground. Therefore, if the massive graviton in bigravity is dark matter, the gravitational wave background can carry information about dark matter. As an example, we assume

Webgravitons is given by the correct order of magnitude of dark matter density. Summarizing, Heisenberg’s uncertainty principle, yields the quanta of length and mass, respectively, the somium and gomidium, which we associate with the graviton, and dark matter.
