The Fermi Paradox refers to the apparent contradiction between the high probability of extraterrestrial life in the universe and the lack of evidence for, or contact with, such civilizations. Given the vast number of stars and potentially habitable planets, many scientists expect that intelligent life should be common. However, we have not yet observed any signs of this life.
This paradox raises questions about the nature of life and the universe. Possible explanations include the idea that advanced civilizations are rare, that they self-destruct before becoming capable of interstellar communication, or that they are deliberately avoiding contact with us.
