Publisher's Synopsis
Some time ago, an unusual book sold over seventy million copies and was translated into twenty-eight languages. It dealt with the possibility of life from the cosmos visiting humanity. This was just one of many surges of public interest in this matter. Unfortunately, the scientific community rarely addresses the causes of these surges. This leaves many confused, not sure what to believe. Indeed, there are always those who try to exploit this confusion.
This book explores the causes of the surges, the stories they generate and the relevant science. It does not presuppose in-depth knowledge on the part of the reader, allowing them to become aware of the sciences behind these stories, and to judge them for themselves.
