Fitting the luminosity data from type Ia supernovae in the frame of the Cosmic Defect theory

TL;DR

This paper reviews the Cosmic Defect theory and demonstrates its effectiveness in fitting luminosity data from Type Ia supernovae, showing comparable results to the standard Lambda-CDM model.

Contribution

It applies the Cosmic Defect theory to supernova data and compares its fit quality with the Lambda-CDM model, highlighting their agreement.

Findings

Cosmic Defect theory fits supernova luminosity data well.

Results are consistent with Lambda-CDM model.

Theories show good agreement in explaining accelerated expansion.

Abstract

The Cosmic Defect (CD) theory is reviewed and used to fit the data for the accelerated expansion of the universe, obtained from the apparent luminosity of 192 SnIa's. The fit from CD is compared with the one obtained by means of $\Lambda $CDM. The results from both theories are in good agreement and the fits are satisfactory. The correspondence between both approaches is discussed and interpreted.
