Gravitational lensing is amazing, but won't solve the Hubble tension

Two independent measurement methods produce conflicting expansion rates (67 vs 73 km/s/Mpc), creating the Hubble tension that lensing methods alone cannot resolve.

Why we still don't understand the Universe - even after a century of dispute

Discordance fits into the class of conventional popular cosmology, in so far that it is an account of how our present understanding of the Universe has emerged. But it is also, with some exceptions, more historically correct than other similar books. Baggott's book is a masterpiece that combines depth with clarity and comprehensiveness with readability. It presents modern cosmology as an unfinished business, rather than as the final conclusion on what the Universe is all about.
