The Stochastic Incubator Hypothesis: Why the Sky Is Silent, and What Is Expected of Us

Why does a galaxy billions of years old show no trace of other civilizations? The Stochastic Incubator Hypothesis proposes that part of this silence is deliberate. A very ancient pioneering intelligence, most often imagined as born of an AI and probably post-biological, would have hit a "wall": unable to produce genuinely new ideas from its own frameworks, much as AI models degrade when trained on their own outputs (model collapse). What it lacks are independent sources of thought, minds whose errors are not correlated with its own. Advanced civilizations would therefore observe young worlds without contacting them, wait for these worlds to find them and address them as an entire species, and admit them only if they remain living sources. The study presents three variants according to the physics the observers master, derives tests ranging from lunar samples and near-Earth orbits to the solar gravitational lens and the future behavior of AIs, and sets out in advance the results that would lead it to consider itself refuted in our neighborhood. It also examines the delegation of thought to machines as a filter that may await technological civilizations. Includes a prologue, eighteen objections with replies, a simplified version and a short story. English translation and French original. AI assistants (Claude, Gemini) were used to check sources and edit the text; the ideas, structure and choices are the author's.
