Fermi’s Paradox: Physicist Enrico Fermi famously asked, “Where is everybody?” Given the vast number of stars and planets, life—and intelligent civilizations—should be common. Yet, we see no evidence of extraterrestrial technology or signals. This contradiction between high probability and absence of contact is Fermi’s Paradox. Proposed solutions include the rarity of life, self-destruction of advanced civilizations, or Earth being deliberately isolated. It highlights gaps in our understanding of biology, technology, and cosmic timescales. The paradox drives astrobiology and SETI, questioning humanity’s place in the universe.
