Conformal Cosmology and Supernova Data

TL;DR

This paper introduces a conformal cosmology framework that redefines key parameters and explains supernova Ia data without requiring a cosmological constant, challenging standard cosmological models.

Contribution

It presents a new conformal cosmology model with redefined parameters and offers an alternative explanation for supernova data without a cosmological constant.

Findings

Reformulation of cosmological parameters within conformal cosmology.

Definition of universe age and luminosity distance in this framework.

Supernova data explained without a cosmological constant.

Abstract

We define the cosmological parameters $H_{c,0}$, $\Omega_{m,c}$ and $\Omega_{\Lambda, c}$ within the Conformal Cosmology as obtained by the homogeneous approximation to the conformal-invariant generalization of Einstein's General Relativity theory. We present the definitions of the age of the universe and of the luminosity distance in the context of this approach. A possible explanation of the recent data from distant supernovae Ia without a cosmological constant is presented.
