Abstract

Motivated by the back-reaction debate, and~some unexplained characteristics of the CMB, we investigate the possibility of some anisotropy in the universe observed around us. To this aim, we build up a novel prediction for the Hubble law for the late universe from a Bianchi type I model, {taken as proof of concept,} transcribing the departure of such model from a Λ\LambdaCDM model. We~dicussed the redshift measurement in this universe, and~finally formalized the Hubble diagram.
