Fermi paradox
Sign in to saveapparent contradiction between the lack of evidence and high probability estimates for the existence of extraterrestrial civilizations
AI overview
The Fermi paradox is the puzzling gap between how likely it seems that alien civilizations should exist somewhere in the universe and the fact that we haven't found any evidence of them. It matters because it forces us to reconsider either our assumptions about how common life is in space, or our understanding of why advanced civilizations might be hard to detect or contact.

The Fermi paradox is the term for the apparent gap between the lack of conclusive evidence of advanced extraterrestrial life and the apparently high likelihood of its existence.
In simple terms, the Fermi paradox asks why, given the vast number of stars and potentially habitable planets in our observable universe, there is no clear evidence of extraterrestrial civilizations.
