Hubble Tension

Most Precise Local Hubble Measurement Sets H0 at 73.5 km/s/Mpc

Robust agreement across many distance tracers points away from a single local error.

Gravitational-Lens Time Delays Deliver New Hubble Constant, Deepening the Tension

New Study Claims the Universe Is Now Decelerating After Supernova Age-Bias Correction

New BAO Analysis Strengthens Local Void Solution to Hubble Tension
