Supernova catalog suggests dark energy is not constant, changing over time

Unified supernova catalog combined with multiple cosmic datasets

2 Sep 10 12:00 PM · 14d ago · 4 articles · 2 sources · development 2 of 2

The research team integrated 30 decades of astronomical observations into a single framework, merging the supernova catalog with data from the Dark Energy Survey, Big Bang relics, and galaxy distribution maps to produce the most comprehensive constraints on dark energy evolution.

“We've rebuilt 3 decades of astronomical observations into a single, consistent framework… Instead of confirming the standard model of cosmology, which assumes dark energy is fixed and unchanging, we have more evidence that dark energy may change over time.”
