DESI Weighs in on Gravity (VIDEO) DOE/Lawrence Berkeley National Laboratory This video is under embargo. Please login to access this video. Caption This simulation shows how more or less gravity affects the positions of galaxies that we observe, changing how they are clustered in a galaxy map. Because different models of gravity predict different clustering of galaxies, DESI researchers can compare observations with simulations to test gravity at cosmic scales.
