| Review: |
This book is about the Fermi paradox: the contradiction between the apparent absence of aliens, and the common expectation that we should see some evidence of their existence. (The question was first posed by Fermi in 1950, triggered, when lunching with friends, by a discussion of the recent spate of flying saucer observations.) Stephen Webb, himself a physicist, lists and discusses fifty proposed solutions to Fermi’s question. These come from scientists working in several disparate fields of science, as well as from science fiction authors. At the end of the book are notes and references for further reading, with subject areas ranging from astronomy to zoology. |
