DESI Provides Best Test Yet of How Gravity Behaves at Cosmic Scales
NSF's NOIRLabResearchers have used the Dark Energy Spectroscopic Instrument (DESI) to map nearly six million galaxies across 11 billion years of cosmic history, allowing them to study how galaxies clustered throughout time and investigate the growth of the cosmic structure. This complex analysis of DESI’s first-year data provides one of the most stringent tests yet of Einstein’s general theory of relativity.
