Fermi Paradox
A paradox proposed by physicist Enrico Fermi concerning the contradiction between the existence of extraterrestrial civilizations and the absence of observational evidence. It is a classic problem in astrobiology and science fiction studies.
Timeline (last 90 days)
The core contradiction of the Fermi paradox is: by probability estimates, intelligent civilizations should have appeared many times and possess interstellar colonization capability, yet humans have so far found no conclusive evidence of any.
If species are extremely hard to wipe out completely, then the solution to the Fermi paradox is either that intelligent life is inherently rare, or that interstellar travel really is extremely difficult.
A science popularization creator proposed in a YouTube video that interstellar colonization is itself self-limiting and that civilizations may implode while competing for limited planets, which is one explanation for the Fermi paradox.
The various explanations of the Fermi paradox (including the dark forest, the great filter, and the colonial implosion hypothesis) serve more as heuristic frameworks to help people think about the boundary conditions of civilizational expansion than as directly testable scientific theories.
The video proposes that if 'sideways' expansion (across universes) is easier than 'outward' expansion, civilizations may have no reason to spread visibly within their native galaxies and little incentive to contact distant aliens, which offers a new solution to the Fermi paradox.
If a civilization only needs to initiate a single viable seed universe rather than colonize an entire galaxy, the motivation for endless outward expansion may diminish, which could serve as an explanation for the Fermi paradox.
The Fermi paradox was proposed by physicist Enrico Fermi in 1950.
The article proposes 'technologically stagnant civilization' as a supplementary explanation for the Fermi Paradox: such civilizations build automation sufficient for their needs and gradually lose the cultural habits required to understand and expand it, disappearing from the universe in silence.
Proposed explanations for the Fermi Paradox include dozens of hypotheses such as the Great Filter hypothesis, the Zoo hypothesis, and the prohibitive cost of interstellar travel.
The Fermi Paradox is named after physicist Enrico Fermi, who posed the question 'Where is everybody?' during a lunch with colleagues in 1950.
