Description
In the author's model of low-energy quantum gravity, the
cosmological redshift, additional darkening of distant objects and
a diffuse cosmic optical background, presumably detected by the
New Horizons mission, can be interpreted, without cosmological
expansion and dark energy, as a result of the scattering of
photons on superstrongly interacting background gravitons. The
constancy of the ratio $H(z)/(1+z)$ in this model is consistent
with observations of the Hubble parameter $H(z)$. There is a
possibility of interpreting dark matter as a gas of virtual
massive gravitons.
