The Fermi paradox or Fermi's paradox, named after Enrico Fermi, is the apparent contradiction between the lack of evidence and high probability estimates, e.g. given by the Drake equation, for the existence of extraterrestrial civilizations. The basic points of the argument, made by physicists Enrico Fermi (1901–1954) and Michael H. Hart (born 1932), are:
