New Local Distance Network reinforces the Hubble tension, challenging standard cosmology
Space scientists assembled decades of local-universe distance measurements into the Local Distance Network, delivering the most precise direct measure of the Hubble constant to date (73.50 km/s/Mpc with ~1.1% uncertainty) and confirming the ongoing discrepancy between early- and late-universe expansion rates. By anchoring many distance indicators—from parallax stars and megamasers to Cepheids and thousands of galaxies—the study shows the Hubble tension persists, suggesting the standard cosmological model may be incomplete and could point to new physics, with future observatories potentially resolving the difference.
