Supernovae Data Suggests Foundational Shift in Cosmological Models

2024-12-23

A new study presents a cosmologically model-independent statistical analysis of the Pantheon+ Type Ia supernovae spectroscopic dataset, improving upon the standard methodology used by Lane et al. By employing the Tripp equation for supernova standardization alone, the study avoids potential correlations in stretch and color distributions. The results strongly favor the 'Timescape' cosmology over the standard ΛCDM model in explaining the data, providing evidence for the need to revisit the foundations of theoretical and observational cosmology. Even when restricting the sample to redshifts beyond conventional scales of statistical homogeneity (z > 0.075), Timescape remains preferred over ΛCDM.
