The speed of this expansion is governed by Hubble's constant, and \u003cem\u003eDiscordance\u003c\/em\u003e tells its troubled history. \u003cp\u003e\u003c\/p\u003eThis unpredictable and fascinating story begins with the first tentative steps to measure the distances to nearby stars and galaxies. It traces the extraordinary interplay between cosmological theory and astronomical observation which has given us the standard Big Bang theory. It was not all plain sailing, and the narrative takes us through the discovery of dark matter, the Hubble Wars of the 1970s, the invention of cosmic inflation, and other crucial scientific moments. Further satellite missions were expected to add to the clarity of our measurements. But from about 2009 onward, the results began to diverge. This is the Hubble tension and perhaps even a crisis. \u003cp\u003e\u003c\/p\u003eJim Baggott clearly and entertainingly guides the reader through this gripping scientific voyage--one littered with crises of confidence, astonishing discoveries, and extraordinary personalities--which still continues today.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Jim Baggott\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Oxford University Press\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 01\/22\/2026\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 336\u003cbr\u003e\u003cb\u003eBinding Type:\u003c\/b\u003e Hardcover\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 1.22lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 9.42h x 6.41w x 1.24d\u003cbr\u003e\u003cb\u003eISBN:\u003c\/b\u003e 9780192864062\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003eReview Citation(s): \u003c\/b\u003e\u003cbr\u003e\u003ci\u003eLibrary Journal\u003c\/i\u003e 12\/01\/2025 pg. 87\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAbout the Author\u003c\/b\u003e\u003cbr\u003eJim Baggott, \u003cem\u003eFreelance science writer\u003c\/em\u003e \u003cp\u003e\u003c\/p\u003e\u003cstrong\u003eJim Baggott\u003c\/strong\u003e is an award-winning science writer.
