Testing the Correlation Between Host Galaxy Mass and Redshift Using the Pantheon Survey Data

This study investigates the relationship between redshift and host galaxy mass using the Pantheon Supernova Survey dataset. The hypothesis that galaxies with identical luminous distances should have the same host mass is tested using statistical correlation analysis. Contrary to expectations from contraction-based cosmological models, our findings indicate. • No statistically significant correlation between redshift and host galaxy mass. • A very strong correlation (r = 0.979) between redshift and photometric distance derived from Type IA Supernovae. • The complete absence of evidence supporting gravitational red shifting as a dominant factor in cosmological redshifts. Furthermore, we identify critical methodological flaws in João Barcellos’ previous analysis, which used only 50 galaxies, ignored the Pantheon dataset, and discarded numerical information in favor of an arbitrary binary classification. Our results support the standard interpretation of redshift as a distance measure rather than an effect of host galaxy mass.
