Overview

• Researchers report in Physical Review Letters that matter falling into black holes could be gradually converted into dark energy.
• The model ties dark-energy growth to the cosmic star-formation history, offering a time-evolving component that fits early- and late-universe data.
• Interpreting DESI data under constant dark energy implied an unphysical negative neutrino mass, which the new framework replaces with a positive value consistent with laboratory constraints.
• The work combines DESI observations with the cosmic microwave background and is described by authors as a hypothesis requiring further tests and community scrutiny.
• DESI, a DOE-managed international survey mapping millions of galaxies, has provided recent measurements that motivated exploring evolving dark energy.
