Assuming a flat $\\Lambda$CDM cosmological model based on BAO and CMB results, redshift dependent deviations of SN~Ia distances are used to constrain mechanisms that would dim light. The analysis is based on the most recent Pantheon SN compilation, for which there is a $0.03\\pm0.01 {\\textrm \\,(\\rm stat)}$ mag discrepancy in the distant supernova distance moduli relative to the $\\Lambda$CDM model anchored by supernovae at $z<0.05$.
