There are 1,000,000,000,000,000,000,000,000 planets in the observable universe. With such an unfathomably large number of planets, it seems naïve to believe that Earth is the only one with intelligent life. But if the universe does, in fact, house other intelligent species, how come we haven't found any yet? A version of this question was posed by a physicist named Enrico Fermi, and its paradoxical nature caused many to label the question the Fermi Paradox. The most popular explanation to Fermi's question, however, is that our technology simply isn't advanced enough.
