Description
The tantalising hint of evidence for dark energy evolution depends on the interplay of data from the cosmic microwave background, baryon acoustic oscillations and Type Ia supernovae. Two recent supernovae data releases, DES-Dovekie and Union3.1, have reduced the preference for evolution compared to previous versions. What has changed? And can the data be trusted?
