Summary
The troubled history of the Hubble constant told in an authoritative, comprehensible, and entertaining manner.
In 1927 Georges Lemaître argued that our universe is expanding, a conclusion rendered more startling by the astronomical data that backed it up, presented two years later by Edwin Hubble. The speed of this expansion is governed by Hubble’s constant, and Discordance tells its troubled history.
This unpredictable and fascinating story begins with the first tent…

Critics Review
This is an exciting romp through the Universe in pursuit of its important and elusive measurement. Highly recommended. * Adam Riess, Nobel laureate 2011, Bloomberg Distinguished Professor at Johns Hopkins University and the Space Telescope Science Institute *
Navigates its way smoothly between the various rivalries … providing a crystal-clear assessment of the challenges of the past and the future prospects for concordance of the Hubble parameter. * Joseph Silk, Emeritus Fellow of New College, Oxford, formerly Savilian Chair of Astronomy at the University of Oxford’s Department of Physics *
Accessible, highly detailed and demanding - and therefore highly rewarding - … Baggott’s well-researched work will be of as much interest to astronomers and physicists as it is to lay readers fascinated by the mysteries of the Universe. * Helge Kragh, Nature *
Jim Baggott is one of the most reliable hands in the business when it comes to exploring complex physics and cosmology issues in an approachable but never over-simplified fashion. * Brian Clegg, Popular Science *
Baggott takes us on an interesting, well informed and clearly explained journey around the important developments and discoveries, especially over the last century or so. * Simon Cocking, Irish Tech News *
Baggott … has written an eminently readable and well-researched book. * A. Spero, CHOICE *
