DESI Confirms Einstein's Gravity Theory Over 11 Billion Years

Nov 20, 2024, 04:50 AM

Recent findings from the Dark Energy Spectroscopic Instrument (DESI) have provided the most precise test to date of Einstein's theory of general relativity on cosmological scales. The study, involving an international collaboration, tracked the growth of cosmic structures over the past 11 billion years, confirming that gravity behaves as predicted by Einstein. The results also suggest constraints on modified gravity theories and provide new limits on neutrino mass, enhancing the understanding of dark energy. Scientists have noted that dark energy, the mysterious force thought to be pushing the universe apart, may not be what it seems, with analyses indicating that the force affecting galaxy movements is not constant.
