Full Description
This book analyzes the likelihood of intelligent civilizations from two different standpoints: firstly, using the famous Drake equation and, secondly, by analyzing some of the most popular hypotheses about the likely behavior of intelligent alien civilizations. The existence of intelligent extraterrestrial civilizations in the universe is one of the most intriguing scientific and philosophical problems. Is it possible that we are the only intelligent species in this incredibly vast universe? Enrico Fermi, one of the greatest physicists of the 20th century, posed the same question during a lunch with his colleagues in 1950. What are the implications for a universe where there is only one intelligent species? The universe may be stranger than we think.
