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 revised and expanded edition of his
book, Webb discusses in detail the (for now!) 75 most cogent 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?
