Emerging Evidence Indicates Universe's Expansion Is Slowing, Challenging Dark Energy Theories

New research suggests that the universe's expansion may be slowing down and dark energy might not be accelerating it anymore, potentially marking a major shift in cosmological understanding. This conclusion is based on findings that challenge the standard model of dark energy, indicating the universe has already entered a phase of decelerated expansion, with future observations from the Vera C. Rubin Observatory expected to further test these results.
