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.
