Early-type Host Galaxies of Type Ia Supernovae. II. Evidence
for Luminosity Evolution in Supernova Cosmology

The authors statement:
'We argue, therefore, that this systematic bias must be considered
in detail in SN cosmology before proceeding to the details
of the dark energy.'
Such a statement is revolutionary on its face.
Is this going to bend the arc of cosmological science?
