On June 13, the collaboration publicly released its first batch of data, with nearly 2 million objects for researchers to explore. He, along with Garcia Quintero and Varela Medina, are co-authors of several of the new papers that describe the use of DESI data to detect the baryon acoustic oscillation signal. General relativity, which is a description of gravity, has two aspects that can be tested: how matter and light move in the universe. DESI will tell us how matter moves in the universe so we will be able to test general relativity to an unprecedented precision.”Insight from DESI into general relativity also could shed light on cosmic acceleration, the observation that the expansion of the universe is speeding up. “Maybe at cosmological scales, general relativity changes into another theory, or there is a modification to it,” Ishak-Boushaki said.
