Yilmaz Theory of SNe 1a Redshift

TL;DR

This paper demonstrates that the Yilmaz gravitational theory can accurately model SNe 1a redshift data without invoking dark energy, relying only on a mean mass-energy density similar to the critical density.

Contribution

It introduces a cosmological model based on Yilmaz theory that fits supernova data without a cosmological constant, challenging the standard dark energy paradigm.

Findings

Yilmaz theory fits SNe 1a data well

No need for dark energy in this model

Requires only mean mass-energy density

Abstract

A redshift-luminosity distance relation in excellent agreement with observations is calculated here for SNe 1a using the Yilmaz gravitational theory. In contrast to the current conventional explanation based on general relativity, the Yilmaz theory does not require a cosmological constant term that implies the existence of "dark energy". The Yilmaz theory requires only one parameter; a mean mass-energy density of the cosmos. The required value is essentially the same as the critical density for a Friedmann-Robertson-Walker cosmological metric. The Yilmaz theory therefore still requires the existence of non-baryonic dark matter.
