What characterizes the significant conflict known as the Hubble Tension?

Answer

A statistical disagreement between $H_0$ derived from the early universe (CMB) and $H_0$ derived from local measurements.

The Hubble Tension arises because measurements of $H_0$ derived from extrapolating physics from the early universe (CMB) yield a slower rate, while direct measurements using local standard candles yield a faster rate.
