Book Description
Are alien civilizations really possible? If extraterrestrials exist, where are they? How likely is it that somewhere in the universe an Earth-like planet supports an advanced culture? Why do so many people claim to have encountered Aliens? In this gripping exploration, scientist Don Lincoln exposes and explains the truths about the belief in and the search for life on other planets. In the first half of Alien Universe, Lincoln looks to Western civilization's collective image of Aliens, showing how our perceptions of extraterrestrials have evolved over time. The roots of this belief can be traced as far back as our earliest recognition of other planets in the universe—the idea of them supporting life was a natural progression of thinking that has fascinated us ever since. Our captivation with Aliens has, however, led to mixed results. The world was fooled in the nineteenth century during the Great Moon Hoax of 1835, and many people misunderstood Orson Welles's 1938 radio broadcast, The War of the Worlds, leading to significant anxiety among some listeners. Our continuing interest in Aliens is reflected in entertainment successes such as E.T., The X-Files, and Star Trek. The second half of the book explores the scientific possibility of whether advanced Alien civilizations do exist. For many years, researchers have sought to answer Enrico Fermi’s great paradox—if there are so many planets in the universe and there is a high probability that many of those can support life, then why have we not actually encountered any Aliens? Lincoln describes how modern science teaches us what is possible and what is not in our search for extraterrestrial civilizations. Whether you are drawn to the psychological belief in Aliens, the history of our interest in life on other planets, or the scientific possibility of Alien existence, Alien Universe is sure to hold you spellbound.

Book Description
Astronomers around the world are pointing their telescopes toward the heavens, searching for signs of intelligent life. If they make contact with an advanced alien civilization, how will humankind respond? In thinking about first contact, the contributors to this volume present new empirical and theoretical research on the societal dimensions of the Search for Extraterrestrial Intelligence (SETI). Archaeologists and astronomers explore the likelihood that extraterrestrial intelligence exists, using scientific insights to estimate such elusive factors as the longevity of technological societies. Sociologists present the latest findings of novel surveys, tapping into the public's attitudes about life beyond Earth to show how religion and education influence beliefs about extraterrestrials. Scholars from such diverse disciplines as mathematics, chemistry, journalism, and religious studies offer innovative solutions for bridging the cultural gap between human and extraterrestrial civilizations, while recognizing the tremendous challenges of communicating at interstellar distances. At a time when new planets are being discovered around other stars at an unprecedented rate, this collection provides a much needed guide to the human impact of discovering we are not alone in the universe.

Book Description
In the twenty-first century, the debate about life on other worlds is quickly changing from the realm of speculation to the domain of hard science. Within a few years, as a consequence of the rapid discovery by astronomers of planets around other stars, astronomers very likely will have discovered clear evidence of life beyond the Earth. Such a discovery of extraterrestrial life will change everything. Knowing the answer as to whether humanity has company in the universe will trigger one of the greatest intellectual revolutions in history, not the least of which will be a challenge for at least some terrestrial religions. Which religions will handle the discovery of extraterrestrial life with ease and which will struggle to assimilate this new knowledge about our place in the universe? Some religions as currently practiced appear to only be viable on Earth. Other religions could be practiced on distant worlds but nevertheless identify both Earth as a place and humankind as a species of singular spiritual religious importance, while some religions could be practiced equally well anywhere in the universe by any sentient beings. Weintraub guides readers on an invigorating tour of the world’s most widely practiced religions. It reveals what, if anything, each religion has to say about the possibility that extraterrestrial life exists and how, or if, a particular religion would work on other planets in distant parts of the universe.

Book Description
What does existing scientific knowledge about physics, chemistry, meteorology and biology tell us about the likelihood of extraterrestrial life and civilizations? And what does the fact that there is currently no credible scientific evidence for the existence of extraterrestrial biospheres or civilizations teach us? This book reviews the various scientific issues that arise in considering the question of how common extraterrestrial life is likely to be in our galaxy and whether humans are likely to detect it. The book stands out because of its very systematic organization and relatively unbiased treatment of the main open question. It covers all relevant aspects of many disciplines required to present the different possible answers. It has and will provide undergraduates with a stimulating introduction to many of these fields at an early stage in their university careers, when they are still choosing a specialty. The difficulties and the range of possible answers to the title question are carefully addressed in the light of present understanding. The resulting perspective is distinctly different from those suggested by most other books on this topic.

Book Description
This book presents key documents from the pre-1915 history of the extraterrestrial life debate. Introductions and commentaries accompany each source document, some of which are published here for the first time or in a new translation. Authors included are Aristotle, Lucretius, Aquinas, Nicholas of Cusa, Galileo, Kepler, Pascal, Fontenelle, Huygens, Newton, Pope, Voltaire, Kant, Paine, Chalmers, Darwin, Wallace, Dostoevski, Lowell, and Antoniadi, among others. Michael J. Crowe has compiled an extensive bibliography not available in other sources. These materials reveal that the extraterrestrial life debate, rather than being a relatively modern phenomenon, has extended throughout nearly all Western history and has involved many of its leading intellectuals. The readings also demonstrate that belief in extraterrestrial life has had major effects on science and society, and that metaphysical and religious views have permeated the debate throughout much of its history. "This is a valuable book that is not available anywhere else. . . . Crowe's purpose is to let the reader see the original words of the authors who discussed other worlds. Crowe puts these documents in context by his substantial introduction and commentary. . . . Such a source book serves an important purpose, and is ideal for teaching and generating discussion in class. The subject is of increasing importance as we find more and more about the possibilities of extraterrestrial life through current disciplines such as astrobiology, bioastronomy, and the Search for Extraterrestrial Intelligence." --Steven J. Dick, Director, NASA History Division, NASA "Having established himself as the world's authority on the history of the debates about extraterrestrial life in the eighteenth and nineteenth centuries, Michael Crowe is perfectly positioned to produce this source book. The introductory commentaries on the excerpts from primary sources he has so judiciously selected reveal again and again that no one else knows this subject as well as he does." --Frederick Gregory, University of Florida "The Extraterrestrial Life Debate gives new meaning to the word 'treasury.' Michael Crowe offers us more than 2000 years of golden materials--wrought by the astonishing alchemy of science, religion, philosophy, and sheer imagination--about a topic as alive today as it ever was: ET, with all his cousins and ancestors. The range of authors the book showcases, and the depth of context Crowe provides, will make his monumental anthology the starting point for future explorations of this rich vein of human thought." --Dennis Danielson, University of British Columbia "There are loads of books on ET, but only a small number of them take a historical approach . . . Anyone interested in the history of the extraterrestrial life debate will be interested in this book; it does complete in a certain way previous historical work done by Steven Dick and Michael Crowe by providing large portions of original texts rather than merely short quotations from them. . . . All the various perspectives, religious, literary, astronomical, philosophical, seem adequately represented. The multidisciplinary aspect of the debate comes across well from the authors selected." --Marie I. George, St. John's University "Extraterrestrials may not have invaded the Earth physically but for centuries they have done so mentally. In many a guise they have appeared not only in works of fiction but also in serious astronomical, philosophical and theological debate. It is impossible to open Michael Crowe's handsome and fastidiously prepared anthology of primary sources without being drawn into endlessly fascinating disputes concerning the possibility and character of extraterrestrial life. Savoring the many twists and turns in controversies that have extended far beyond the confines of popular astronomy, Professor Crowe has provided students and experts alike with a generous and indispensable resource. It is difficult to resist his invitation to investigate for ourselves the innumerable, and often surprising, ways in which the idea of intelligent life on other worlds has shaped and been shaped by perennial Earthly concerns." --John Hedley Brooke, Andreas Idreos Professor Emeritus of Science and Religion, University of Oxford
