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.

The Fermi Paradox - Wait But Why ~ Physicist Enrico Fermi felt something too—”Where is everybody?” A really starry sky seems vast —but all we’re looking at is our very local neighborhood. On the very best nights, we can see up to about 2,500 stars (roughly one hundred-millionth of the stars in our galaxy), and almost all of them are less than 1,000 light years away from us (or 1% of the diameter of the Milky Way).

Fermi-Paradoxon – Wikipedia ~ Das Fermi-Paradoxon ist ein Gedankengang des Physikers Enrico Fermi aus dem Jahr 1950. Fermi ging davon aus, dass es extraterrestrische Intelligenz gibt, die technisch hochentwickelte Zivilisationen über Millionen von Jahren aufrecht erhalten kann. In dieser Zeitspanne sollte es mittels interstellarer und intergalaktischer Raumfahrt möglich sein, ganze Galaxien zu kolonisieren – und der .

The Space Review: The other side of the Fermi paradox ~ The Fermi paradox is based on the premise that it is natural, logical and right for extraterrestrial civilizations to colonize space. The other side of the Fermi paradox is that it is natural, logical, and right for human civilization to colonize space. Anti-human-spaceflight advocates tend to hold the contradictory idea that colonization is alright for extraterrestrials, but wrong and immoral .

Planetarium hypothesis - Wikipedia ~ The planetarium hypothesis, conceived in 2001 by Stephen Baxter, attempts to provide a solution to the Fermi paradox by holding that our astronomical observations represent an illusion, created by a Type III civilization capable of manipulating matter and energy on galactic scales. He postulates that we do not see evidence of extraterrestrial life because the universe has been engineered so .

A Physicist Has Proposed a Pretty Depressing Explanation ~ As Berezin sees it, the problem with some proposed solutions to the Fermi Paradox is they define alien life too narrowly. . Berezin says the only parameter we should concern ourselves with – in terms of defining extraterrestrial life – is the physical threshold at which we can observe its existence. "The only variable we can objectively measure is the probability of life becoming .

Hanson a initialement élaboré sa théorie dans le but de trouver une explication au fait qu'aucune civilisation .

CCC and the Fermi paradox / SpringerLink ~ Within the scheme of conformal cyclic cosmology (CCC), information can be transmitted from aeon to aeon. Accordingly, the “Fermi paradox” and the SETI programme --of communication by remote civilizations-- may be examined from a novel perspective: such information could, in principle, be encoded in the cosmic microwave background. The current empirical status of CCC is also discussed.
