New cosmic lensing test sharpens the Hubble tension and hints at new physics
It’s a powerful technique, but small uncertainties at each step can add up, something critics argue may be behind the Hubble tension. The new study bypasses this entire ladder using a method called ...
Physicists have improved the accuracy of a technique that uses variable stars to measure distances in the universe, providing a new figure for its expansion rate. When you purchase through links on ...
New gravitational lensing measurements by the TDCOSMO Collaboration support the Hubble Tension, confirming differences between Early and Late Universe Hubble Constant values using updated ...
NASA has released a huge new report that astronomers are calling Hubble’s magnum opus. Analyzing 30 years of data from the famous space telescope, the new study makes the most precise measurement yet ...
