A proposed early population of supermassive stars could seed the Universe’s first giant black holes, produce an early ionizing background, and alter signals that currently push models toward 'evolving dark energy.' By accounting for JWST’s ultra‑early black holes and hints of early ionization, this astrophysical fix may reconcile CMB, large‑scale structure, supernova, and BAO data without modifying dark energy.
— It redirects dramatic 'new physics' headlines toward an astrophysical explanation and highlights how model interpretation can drive perceived crises in cosmology.
