Given the fact that there are perhaps 400 billion stars in our Galaxy alone, and perhaps 400 billion galaxies in the Universe, it stands to reason that somewhere out there, in the 14-billion-year-old cosmos, there is or once was a civilization at least as advanced as our own. The sheer enormity of the numbers almost demands that we accept the truth of this hypothesis. Why, then, have we encountered no evidence, no messages, no artifacts of these extraterrestrials? In this second, significantly revised and expanded edition of his widely popular book, Webb discusses in detail the (for now!) 75 most cogent and intriguing solutions to Fermi's famous paradox: If the numbers strongly point to the existence of extraterrestrial civilizations, why have we found no evidence of them? Reviews from the first edition: "Amidst the plethora of books that treat the possibility of extraterrestrial intelligence, this one by Webb ... is outstanding. ... Each solution is presented in a very logical, interesting, thorough manner with accompanying explanations and notes that the intelligent layperson can understand. Webb digs into the issues ... by considering a very broad set of in-depth solutions that he addresses through an interesting and challenging mode of presentation that stretches the mind. ... An excellent book for anyone who has ever asked ‘Are we alone?’." (W. E. Howard III, Choice, March, 2003) "Fifty ideas are presented ... that reveal a clearly reasoned examination of what is known as ‘The Fermi Paradox’. ... For anyone who enjoys a good detective story, or using their thinking faculties and stretching the imagination to the limits ... ‘Where is everybody’ will be enormously informative and entertaining. ... Read this book, and whatever your views are about life elsewhere in the Universe, your appreciation for how special life is here on Earth will be enhanced! A worthy addition to any personal library." (Philip Bridle, BBC Radio, March, 2003) Since gaining a BSc in physics from the University of Bristol and a PhD in theoretical physics from the University of Manchester, Stephen Webb has worked in a variety of universities in the UK. He is a regular contributor to the Yearbook of Astronomy series and has published an undergraduate textbook on distance determination in astronomy and cosmology as well as several popular science books. His interest in the Fermi paradox combines lifelong interests in both science and science fiction.

If we have learned anything from recent advances in cosmology and astronomy, it is that we have only barely begun to comprehend the vastness of our universe and all that it contains. For Christians, this raises some fascinating questions: If there are intelligent beings out there, what would be their relationship to what Christianity claims is a special history on Earth of life with God? Would the fact of persons on other planets banish or modify our understanding of God? Would it reduce the importance of Jesus? What role might goodness and evil play in extraterrestrial civilizations? Might God have incarnated himself among other races of creatures, as he became incarnate as Jesus among us? Respectful of the sciences that disclose the reality of the universe, Thomas O'Meara wonders about good and evil, intelligence and freedom, revelation and life as they might exist in other galaxies. In this book, one possible aspect of the universe we live in meets the perspective of Christian revelation.

In E. M. Forsters Dystopie leben die Menschen in einer unterirdischen, abgekapselten Welt mit allem Komfort: Das ganze Leben ist durch die Dienstleistungen der »Maschine« perfekt geregelt. Die Menschen haben kein Bedürfnis mehr nach persönlichen Begegnungen, man kommuniziert nur über die Maschine, die über allem wacht. Ihr Handbuch ist zu einer Art Bibel geworden, die Menschen sind gefangen in ihrer absoluten Abhängigkeit von der Technik, die sie nicht mehr kontrollieren können. Doch nach und nach geht das Wissen, das hinter der Maschine steckt, verloren und das System wird anfällig für Pannen ... E. M. Forsters visionäres Werk wirft Fragen auf, die von großer Aktualität sind: Wie kann der Mensch seine Selbstbestimmung wahren gegenüber Maschinen, die immer stärker unser Leben bestimmen?
