WebApr 22, 2016 · We consider the possibility that the massive graviton is a viable candidate of 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 … WebNov 9, 2016 · The electromagnetic field generated by a photon is much stronger than the associated gravitational field. When a photon is falling in the gravitational field, it goes from a low layer to a higher ...

This approach poses a lot of problems because a) gravitons do not exist as far as we know, b) gravitons with mass have all sorts of complicated theoretical implications that baffled physicists since the 1930s, and c) the math to resolve these implications raises its own weird questions that need to be answered.
WebWhile 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 … WebJul 30, 2024 · We detailed our discovery of a chiral enhancement in the production cross sections of massive spin-2 gravitons, below the electroweak symmetry breaking scale, that makes them ideal dark matter candidates for the freeze-in mechanism. The result is independent of the physics at high scales, and points toward masses in the keV- MeV …
