Gravity has shaped our cosmos. Its attractive influence turned tiny differences in the amount of matter present in the early universe into the sprawling strands of galaxies we see today.
A new study using data from the Dark Energy Spectroscopic Instrument, or DESI, has traced how this cosmic structure grew over the past 11 billion years, providing the most precise test to date of gravity at very large scales.
DESI is an international collaboration of more than 900 researchers from more than 70 institutions around the world, including the University of Michigan, and is managed by the Department of Energy’s Lawrence Berkeley National Laboratory.
