Universe

A Guide to Everything

A sweeping, reflective history of how we’ve tried to understand the universe.

The physical universe is a most peculiar concept, not only different from the objects it contains but also from space itself. Cosmology—the science that seeks to explain it—has always differed from other sciences, drawing on philosophy and even theology. These influences remain, even in today’s data-driven cosmological models. This accessible and far-reaching book traces the development of cosmological thought from antiquity to the twenty-first century, with particular focus on the foundational work of Einstein, Hubble, and others in the early twentieth century. It explores how modern theories rest on a surprisingly fragile base and argues that many cosmic mysteries may remain permanently unsolved. Rich in historical and philosophical insight, this is a lucid guide to what we know—and perhaps cannot know—about the universe.

Reviews

“In this book Kragh, one of the premier historians of cosmology, offers a lively account of our conceptions of the universe from Aristotle to the present. Written for a broad audience, it also addresses ultimate pressing mysteries like what came before the Big Bang; the ultimate fate of galaxies, black holes, and life; and whether we may live in a multiverse. Highly recommended for anyone interested in the changing conceptions of our place in the universe.”

Steven J. Dick, former NASA chief historian

“Kragh is the leading historian of scientific studies of the universe. He also possesses a rare ability to make complex ideas accessible and understandable. In Universe, we see him in sparkling form, presenting a lucid and engaging account of how people have envisioned the universe from ancient Greece to the twenty-first century. A reader could not ask for a better guide to this captivating story.”

Robert Smith, professor of history, University of Alberta
