The DESI collaboration published a new analysis of dark energy using their first three years of collected data, which spans nearly 15 million galaxies and quasars. This analysis combined the DESI data with information from studies of the cosmic microwave background, supernovae, and weak gravitational lensing. The standard model of cosmology struggles to explain all the observations when taken together — but a model where dark energy’s influence changes over time seems to fit the data well.
