黑暗森林法則是劉慈欣科幻小說中的哲學假說,解釋費米悖論,但非形式化公理系統。
黑暗森林法則源自劉慈欣的科幻小說《三體》,將宇宙比作黑暗森林,每個文明如帶槍獵人必須隱藏自己[1]。該法則基於幾個核心前提:文明優先追求生存,宇宙物質有限,文明間存在信息不對稱與信任困難。由於無法判斷他文明的真實意圖,且技術可能發生快速飛躍,任何文明一旦發現他者,最理性的選擇往往是先發制人或保持沉默[2]。這種「猜疑鏈」導致所有文明都傾向隱匿蹤跡,解釋了為何人類未觀測到明確的外星文明跡象。然而,黑暗森林法則並非嚴格的公理化理論,而是一套非形式化的哲學推論框架與思想實驗,用於解釋費米悖論的社會學模型,具有啟發性但未經經驗驗證。
