The Forbidden City Hypothesis: An Alternative to the Dark Forest in the Context of the Fermi Paradox

This paper proposes an alternative to the Dark Forest hypothesis in the context of the Fermi paradox. A single modification to the foundational axioms—the removal of the resource constraint—eliminates the structural inevitability of inter-civilizational conflict and opens the space for a fundamentally different model. Discussions of the Fermi paradox often implicitly assume that a civilization overcoming major technological barriers preserves its identity indefinitely. However, no known resilient complex system demonstrates the preservation of a single substrate as a condition for longevity. On the contrary, the stability of biological, cultural, and institutional systems is ensured by the preservation of the pattern through the succession of substrates. The hypothesis of an immortal galactic civilization is not an extension of an observed pattern, but a highly restrictive additional assumption unsupported by known examples. A more cautious premise is that civilizational longevity is achieved not through the immutability of the subject, but through the transfer of function to new substrates. Under this logic, the behavior of an elder civilization is modeled through a historically realized institution: the Imperial Court of the Forbidden City. We analyze its structural properties: covert observation, opaque criteria, multiple outcomes, and a mechanism of role succession devoid of biological linkage. In this model, the Great Silence is not an anomaly, but a predictable consequence.
