Latest James Webb data hints at new physics in Universe’s expansion
SMRTR summary
New observations from the James Webb Space Telescope confirm Hubble's measurements of the Universe's expansion rate, supporting a discrepancy with theoretical models. The study examined 1,000 Cepheid variable stars in distant galaxies, yielding a Hubble constant of 72.6 km/s/Mpc. This discrepancy suggests potential new physics, such as early dark energy or exotic particles, to explain the Universe's expansion.
