New findings shed light on the expanding univ

<p>To study dark energy&rsquo;s effects over the past 11 billion years, the <a href="https://www.desi.lbl.gov/">Dark Energy Spectroscopic Instrument</a> (DESI) collaboration has created the largest 3D map of the cosmos ever constructed using the most precise measurements to date. This is the first time scientists have measured the expansion history of the young universe with a precision better than 1%. On April 4, Dr. Mustapha Ishak-Boushaki of&nbsp;The University of Texas at Dallas and his DESI colleagues presented analyses of the first year of data collected by the DESI experiment at a meeting of the <a href="https://april.aps.org/">American Physical Society</a> in Sacramento, California.</p>
