Ferris is a journalist who has written several successful popular works about modern astronomy (e.g., The Mind’s Eye, Bantam, 1993). Here he reviews the current state of scientific cosmology, including the now-considerable overlap between astronomical findings and the theories of elementary particle physicists. (The parenthetical plural in the title is an allusion to theories that suggest the cosmos contains a multiplicity of universes.) Ferris adheres to the orthodox Big Bang theory, giving little attention to its critics, but he is candid about the many uncertainties in modern cosmology. He writes clearly, often with considerable eloquence. But given the intrinsic difficulties and unavoidable jargon of the field, a lay reader will have to give this book close attention to get its full value. Highly recommended for public and academic libraries.
