Discordance. The Troubled History of the Hubble Constant, Hardback/Jim (Freelance science writer) Baggott

The speed of the expansion of the universe is governed by the Hubble constant. Discordance tells of its troubled 100-year history, from tentative steps to measure the distances of nearby stars to orbiting telescopes peering into the far reaches of space. But recent results hint at more trouble ahead: the 'Hubble tension'. The story is not over yet.
