Architectural framework demonstrates orbital space as an optimal industrial substrate, suggesting potential thermodynamic decoupling of civilization from Earth's biosphere.
Arcstone Computational Spine (ACS) — Academic Whitepaper Suite (Paper 10) Aerospace design paradigms have historically treated orbital space as a hostile, high-risk void. Engineering efforts have focused primarily on shielding equipment against extreme thermal gradients, solar particle events, microgravity, and hard vacuum. This paper establishes the Inverted Substrate Paradigm. By shifting perspective from survival to utility, orbital space reveals itself not as an environment of hazards, but as an optimized physical substrate uniquely suited for high-metabolism civilizational operations. By leveraging native features and bridging them through zero-touch Matter-as-a-Service (MaaS) e-commerce airlocks and dual-token expert fulfillment loops, humanity can migrate its energy-intensive manufacturing, primary power generation, and dense computational infrastructure off-planet. This transition achieves thermodynamic decoupling: civilizational capability expands exponentially while Earth's biosphere remains protected from industrial entropy dissipation (S_gen).
