Extensive Supernova Catalog Suggests Dark Energy May Not Be Constant

An international research team has compiled the largest-ever catalog of supernovae, featuring 2,884 Type 1a supernovae from 30 years of observations. This comprehensive dataset challenges the prevailing theory that dark energy, the force behind cosmic expansion, remains constant. The findings could lead to a significant revision of our understanding of the Universe's evolution and its ultimate fate, impacting fundamental physics and cosmology.
