The Local Universe’s Expansion Rate Is Clearer than Ever, but Still Doesn’t Add Up

A global astronomical collaboration achieves a 1% precision measurement of the Universe’s local expansion rate

Astronomers measure Hubble constant with 1% precision at 73.5 km/s/Mpc, strengthening Hubble tension and raising questions on universe expansion and dark energy.

Universe’s expansion rate: ‘Something doesn’t add up’

Most precise measurements yet of the local Universe's expansion rate

Hubble tension deepens as new study measures expansion rate. Continue reading Most precise measurements yet of the local Universe’s expansion rate on Tech Explorist.

Local Universe Expansion Rate More Precise Than Ever

An international consortium of astronomers has announced one of the most precise measurements to date of the local Universe’s expansion rate, a fundamental parameter in cosmology known as the Hubble constant. This milestone has intensified one of contemporary astrophysics’ most perplexing dilemmas, famously dubbed the “Hubble tension.” The work, spearheaded by the H0 Distance Network […]

The Local Universe’s Expansion Rate Is Clearer Than Ever, but Still Doesn’t Add Up - A new synthesis of astronomical measurements confirms a persistent mismatch that could point to physics beyond current models

An international collaboration of astronomers has produced one of the most precise measurements yet of how fast the local Universe is expanding. The result deepens one of the most significant challenges in modern cosmology. John Blakeslee, astronomer at NSF NOIRLab, funded by the U.S. National Science Foundation, is a member of the collaboration, and telescopes across two NSF NOIRLab Programs contributed data.
