A quantum gravitational model of redshifts

Abstract

The main features of an alternative model of redshifts are described here. The model is based on conjectures about an existence of the graviton background with the Planckian spectrum and a super-strong character of quantum gravitational interaction. This model is con- nected with the assumed quantum mechanism of gravity. A behavior of two theoretical functions of a redshift z in this model - the geometri- cal distance r(z) and the luminosity distance DL(z) - and an existence of two different cosmological horizons for any observer are discussed.
