Opis

Given the fact that there are perhaps 400 millionstars in our Galaxyalone, and perhaps 400 million galaxies in the Universe, it stands toreason 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 enormities of the numbers almost demand that we accept thetruth of this hypothesis. Why, then, have we encountered no evidence,no messages, no artifacts of these extraterrestrials? Webb discussesin detail the 50 most cogent and intriguing solutions to Fermi'sfamous paradox: If the numbers strongly point to the existence ofextraterrestrial civilizations, why have we found no evidence of them?
