The Nobel Prize Winner Who Thinks We Have the Universe All Wrong

Adam Riess, a Nobel laureate physicist, is challenging the cosmological model he helped establish. His precise galaxy distance measurements reveal a discrepancy in the universe's expansion rate, known as the Hubble tension. This suggests dark energy, the force accelerating cosmic expansion, may be changing over time. Recent data supports this idea, indicating dark energy might have weakened billions of years ago. If confirmed, these findings could reshape our understanding of the universe's future, potentially replacing the theory of heat death with alternative scenarios.
