The Biological Universe

Wallace Arthur addresses the most exciting question in science: 'Are we alone?' His brilliant exposition argues convincingly that we are likely to go through a Copernican revolution regarding the biological universe and discover that we are not at its centre. Avi Loeb, Chair of the Harvard Astronomy department

Working his way up from first principles of physics, chemistry, and biology, Wallace Arthur asks what is needed for life to exist. In his familiar readable style, he then asks whether these requirements are likely to be found elsewhere in the universe, and answers with a resounding 'Yes'. Anyone who works on the evolution of life on Earth will have asked themselves similar questions. Arthur’s presentation of the questions, and of the answers, is both enjoyable and eye-opening.

An engaging, well-informed, and accessible guide to one of the great questions. Thoroughly enjoyable and unputdownable. Peter Atkins, Emeritus Professor of Physical Chemistry, University of Oxford, and fellow of Lincoln College 

Wallace Arthur takes us on a fascinating journey to discover if and how our living planet is unique in the universe. In his characteristically engaging style, he propels his story with sharp questions, arresting details, and vivid explanations, so that we arrive, via photosynthesis-stealing slugs and the extremes of extraterrestrial atmospheres, at a new understanding of ourselves and our world. Ronald Jenner, Natural History Museum, London, UK 

The Biological Universe performs a fascinating dissection of our tree of life, asking which of its features we might share with other such trees on worlds throughout the Galaxy. A truly unique perspective on finding life in the Universe, which starts with who is eating whom in the soil under our feet. Elizabeth Tasker, author of The Planet Factory 

In this thought-provoking book, Arthur's deep knowledge of life and its myriad manifestations, coupled with a cosmologist’s understanding of the cosmos at large, enables him to explore one of science’s greatest mysteries - how the biological and physical universes relate to one another. Does life exist beyond this planet? What form would it take? How could we detect it? Arthur musters fact, logic, and intuition, in his far-reaching attempt to nail down life’s place within the wider cosmic dimension. Addy Pross, Ben-Gurion University of the Negev, Israel 

Wallace Arthur’s book The Biological Universe is highly significant. We will soon know if we are alone in the universe. The next few years could provide us with this long-sought answer. This book, extremely well written, tells us how. Simon ‘Pete’ Worden, Executive Director, Breakthrough Initiatives, Luxembourg and USA
