>Supernova (SN) cosmology is based on the key assumption that the luminosity standardization process of Type Ia SNe remains invariant with progenitor age. However, direct and extensive age measurements of SN host galaxies reveal a significant () correlation between standardized SN magnitude and progenitor age, which is expected to introduce a serious systematic bias with redshift in SN cosmology.
They’re questioning the validity of the luminosity of Type 1a supernova?

But will it still be an „open“ universe, with an eternal and ever-slower deceleration, or will it eventually collapse into a Big Crunch?

Its still a heat death
Unless we do something to reverse entropy

So…. what, dark energy has turned off suddenly?

I know this is a crazy opinion, but it seems to me that much of the debate in astrophysics today could be solved with the realization that the laws of physics are slightly different in every galactic supercluster. We can’t apply Earth physics to everything we see out there.

Eh this study is highly controversial. They argue that we are headed for a Big Crunch. This theory had previously been disproven when the Higgs Boson was correctly measured. Cosmologists still overwhelmingly agree that the universe is headed for a cold death.
