New Webb Telescope Data Challenges Long-Standing Hubble Tension

Analysis suggests the universe's expansion rate may be more consistent than previously thought, raising questions about established measurements.

  • Scientists used the James Webb Space Telescope to measure the universe's expansion rate, focusing on 10 nearby galaxies.
  • The new data indicates an expansion rate of 70 km/s/Mpc, which aligns closely with earlier measurements.
  • This finding suggests there may not be a significant discrepancy, known as the 'Hubble tension,' between different measurement methods.
  • The study employed three independent methods, all yielding consistent results within the margin of error.
  • Further observations with the Webb Telescope are expected to provide more clarity on this cosmological issue.
