Universe Expansion Rate: New Method Adds to Hubble Tension

• The universe's expansion rate (Hubble Constant) is a mystery due to conflicting measurements from different methods.
• The "Hubble Tension" describes the discrepancy between measurements: ~73 km/s/Mpc (supernovae) and ~67 km/s/Mpc (CMB).
• Scientists from the University of Tokyo developed a new "Time Delay Cosmography" technique using gravitational lensing.
• This new method yielded a Hubble Constant of ~73 km/s/Mpc, aligning with local universe measurements, not the Big Bang model.
• This suggests a fundamental gap in our understanding of the universe, potentially requiring new physics.

Why It Matters: New universe expansion data suggests current physics models are incomplete.
