Simulating a Millennium: The Mechanics of Civilisation Survival

The study utilized 200 simulation runs for each of the 10 scenarios, testing variables such as governance structures, resource management, and resilience to catastrophic events. Results varied wildly, with the "duty cycle"—the time a civilization remains technologically active—fluctuating between 38 and 100 percent. While the "Golden Age" and "Out of Eden" models avoided collapse entirely, most scenarios faced repeated failures. The "Ouroboros" model proved particularly resilient, maintaining an 87 percent duty cycle by cycling through phases of destruction and reconstruction.

Resource consumption rates and recovery capacity emerged as the primary determinants of survival. The team proposed the deployment of "recovery kits"—repositories of essential knowledge regarding agriculture, medicine, and energy—to facilitate rebuilding after disasters. This approach mirrors existing initiatives like the Svalbard Global Seed Vault, which hedges against planetary-scale loss.

These findings complicate the search for extraterrestrial life. If civilizations frequently fluctuate between technological capability and dormancy, their window of detectability from Earth shrinks significantly. While the researchers emphasize that their model relies on simplified assumptions and remains a preprint awaiting peer review, it provides a framework for understanding how societies might navigate the transition from rapid expansion to long-term sustainability.
