Cosmic Acceleration Under Scrutiny: New Supernova Catalog Hints Dark Energy May Evolve
TL;DR
A record 2,884 Type Ia supernovae form the largest catalog to date, integrated with DES data and reanalyzed across telescopes to create a consistent history of cosmic expansion; the results add to hints that dark energy may vary over time, challenging the standard constant-dark-energy model and aligning with DESI signals, with future surveys like DEBASS expected to provide further clarity.
