A Nobel Physicist Says We May Have Misunderstood the Universe — JWST Data Changes Everything

The universe may be more incomplete than modern cosmology expected. New observations from the James Webb Space Telescope (JWST) are intensifying the debate around the Hubble tension — one of the biggest mysteries in astrophysics. Nobel Prize-winning physicist Adam Riess and his team measured the universe expansion rate using the cosmic distance ladder and found results that conflict with predictions based on the cosmic microwave background observed by the Planck satellite. The discrepancy challenges the standard Lambda-CDM cosmological model and raises major questions about dark energy, dark matter, and the physics of the early universe. From Webb telescope discoveries to massive galaxies appearing far too early after the Big Bang, modern astrophysics is confronting evidence that may reshape how humanity understands deep space and cosmic history.
