Nobel Prize Winner Warns: “This Isn’t Our Universe” — James Webb Found Something Strange

Nobel Prize winner Adam Riess says we may have "misunderstood the universe." The James Webb Space Telescope was supposed to settle a growing contradiction in cosmology. Instead, it made it worse. Two methods of measuring how fast the universe is expanding give two different answers. One says 67. The other says 73. The gap is too large to ignore, and after Webb confirmed the measurements with unprecedented precision, the possibility of a simple error has been ruled out. Something in our understanding of the cosmos is either missing or wrong. This video covers the Hubble tension, the impossible early galaxies Webb discovered, the rival teams fighting over the data, the mysterious "little red dots" that fooled astronomers, and why some physicists now believe we may need entirely new physics to explain what we're seeing.
