Supernovae Cosmology may be wrong

In this work and in their previous papers they suggest that the dimming of distant supernovae can be at least partially explained by the age of the supernovae progenitor rather than cosmic acceleration. Their work now seems to agree much more with findings from DESI BAO + CMB, which suggest a much more complicated dark energy than simple vacuum energy. In this new analysis, the expansion of our universe could be actually decelerating at current times.
