Overview

• DESI has created the largest 3D map of the universe, offering unprecedented detail in mapping galaxies and quasars.
• The map allows for the most precise measurements of dark energy and the universe's expansion over the last 11 billion years.
• Initial findings show basic agreement with the current model of the universe, but also hint at potential differences suggesting dark energy may be evolving.
• The measurement of the Hubble constant has narrowed, deepening the crisis in cosmology due to differing results from standard candles and rulers.
• DESI's results, combined with cosmic microwave background data, support a Hubble constant that challenges higher velocity measurements.
