Extraterrestrial Life & the Fermi Paradox
Dark Forest Hypothesis
Proposes that civilizations stay silent and hidden because contact with an unknown civilization is existentially dangerous, making concealment and preemptive threat-elimination the only rational long-term survival strategy.
Proponents
Liu Cixin (originated the concept in his novel "The Dark Forest"); discussed since as a serious game-theoretic hypothesis by some astrophysicists and philosophers
Evidence For
Offers a game-theoretic explanation for galactic silence that does not require life or intelligence to be rare.
Evidence Against
Mainstream SETI researchers argue its core assumption — that all advanced civilizations converge on aggressive concealment — rests on an analogy to human conflict that may not generalize to other minds or motivations.
