"Unveiling the Universe: New 3D Map and Dark Energy Data Challenge Cosmological Theories"

An international team, including the Perimeter Institute and the University of Waterloo in Canada, has created a detailed three-dimensional map of the universe, charting its expansion over 11 billion years. Using the Dark Energy Spectroscopic Instrument (DESI), the map provides new insights into dark energy and offers the most precise measurements to date of the universe’s expansion by observing galaxies and gas clouds. DESI aims to enhance scientists’ understanding of neutrinos and has made the largest 3D map of the universe to date, shedding light on the fundamental question of dark energy.
