Covers the Hubble tension crisis: JWST confirmed the local expansion rate at ~73 km/s/Mpc, stubbornly diverging from the early-universe prediction of ~67, ruling out measurement error with high confidence. Also examines JWST's discovery of unexpectedly massive early galaxies — some initially explained by black-hole imposters inflating brightness, but a residual excess (~2x expected) persists alongside anomalies like fully-formed spiral galaxies in the young universe.
Alösha's take: Solid 30-min primer on why our standard model of cosmology may actually be cracking — real data, real debate, no filler.
