Another possible interpretation of SN 1a data - without kinematics: Comments on the paper astro-ph/0402512 by A. Riess et al

TL;DR

This paper proposes a non-expanding universe model that explains supernova luminosity data without dark energy, fitting observations at low redshift and suggesting spectral deformations at higher redshift due to photon energy loss mechanisms.

Contribution

It introduces a novel interpretation of supernova data using a non-expanding universe model without dark energy, emphasizing photon energy loss effects.

Findings

Good fit to supernova data at z<0.5

Discrepancies at higher z explained by spectral deformations

Model challenges standard dark energy paradigm

Abstract

It is shown here that for redshifts $z < 0.5$ the luminosity distance, which is predicted in author's model astro-ph/0005084 v2, fits well supernova observational data of astro-ph/0402512 by A.Riess et al. Discrepancies for higher $z$ would be explained in the model as a result of specific deformation of SN spectra due to a discrete character of photon energy losses. The model does not require any dark energy; it is based on the conjecture that gravitons are super-strong interacting particles fulfilling a flat non-expanding universe.
