Extraterrestrial IntelligenceIf extraterrestrial intelligence exists, then positive detection would be the greatest scientific discovery of all time. By what criteria should we judge whether we are alone in the cosmos, and how should we set about detecting extraterrestrials? Jean Heidmann answers these questions in this engaging discussion of extraterrestrial intelligence. Through a clear explanation of the many issues involved, including new and updated information, the entire subject of extraterrestrial intelligence is explained: the expansion of searches in space, the habitable zones in our universe, and what might happen if actual contact takes place. |
