"Helge 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"In this book Helge 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
