Hart, is the apparent contradiction between the high probability of the existence of extraterrestrial civilizations, and the lack of any evidence for such civilizations. Now Edward Snowden -- the man who leaked evidence that the United States has been trawling the phone records of Americans for years -- may have an answer to the Fermi paradox in computer encryption. On celebrity astrophysicist Neil deGrasse Tyson's "StarTalk" audio show this week, Snowden suggests that a need to keep communications secure could mean that alien signals are simply too well encrypted to be distinguished from background noise.
