In a 1950 conversation at Los Alamos, four world-class scientists generally agreed, given the size of the Universe, that advanced extraterrestrial civilizations must be present. But one of the four, Enrico Fermi, asked, "If these civilizations do exist, where is everybody?" Given the fact that there are perhaps 400 million stars in our Galaxy alone, and perhaps 400 million 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. Webb discusses in detail the 50 most cogent and intriguing solutions to Fermi's famous paradox.

"Where Is Everybody? is a delightful mental romp. With a light-hearted, enthusiastic tone, Webb offers lively coverage of UFOs, crop circles, and the books of Erich von Däniken, the infamous proponent of the idea that aliens visited the Earth in the distant past. Science-fiction fans will enjoy the frequent references to Star Trek, and science buffs will appreciate mention of the ideas of Carl Sagan, Fred Hoyle, Frank Drake, and Freeman Dyson. This book is a must-read for anyone who has ever pondered the question, "Are we alone?" --Astronomy

"Stephen Webb provides a fascinating a guide to the rousing scientific debate over the existence of extraterrestrial life in Where Is Everybody? Fifty Solutions to the Fermi Paradox and the Problem of Extraterrestrial Life ... . The reader of the book will get a very broad education in many basic fields of science, including astronomy, biology, chemistry, geology, meteorology and even psychology. Webb is clear, entertaining and fair to every one of the 50 opinions, and even gives his own solutions in a concluding chapter." --Jeffrey Marsh, Washington Times, January, 2003

"Webb offers coherent, understandable, and sometimes humorous coverage of a diverse range of topics. He provides readers with non-trivial insights into research fields they may not have encountered previously . . . I think everyone who has ever considered the possibility that other intelligent civilizations exist elsewhere within our galaxy will enjoy Where Is Everybody? They will find much to agree with, and much to argue about, in this very accessible volume." --Science
