Overview

• DESI's latest results, presented at the American Physical Society's Global Physics Summit, strengthen evidence that dark energy may not be constant but evolving over time.
• The analysis uses data from the first three years of DESI's survey, including nearly 15 million galaxies and quasars, doubling the dataset from its initial findings.
• Dark energy's potential evolution is indicated by statistical significance levels ranging from 2.8 to 4.2 sigma, though it has not yet reached the 5-sigma threshold for discovery.
• DESI's findings are supported by complementary datasets, including the cosmic microwave background, supernovae, and weak lensing observations.
• Data Release 1, containing 13 months of survey data, is now publicly available to support further astrophysical research and theoretical advancements.
