Reinterpreting the Fermi Paradox through Intensive Evolution of Advanced Civilizations Based on Superstring Theory and the Holographic Principle
Year: 2026

Abstract: This paper derives the quantitative and logical consequences of the evolutionary trajectory of an advanced technological civilization—one that has transcended the Kardashev scale—within the framework of 10-dimensional Type IIB superstring theory, 11-dimensional M-theory, and the AdS/CFT correspondence (the holographic principle). While conventional astrobiology and SETI (Search for Extraterrestrial Intelligence) have traditionally viewed civilizational development as an extensive expansion through three-dimensional space, this study—by comparing thermodynamic computational efficiency (constrained by the Bekenstein bound and the Margolus-Levitin theorem) against relativistic communication delays—demonstrates that a mature civilization is far more likely to pursue an "intensive transition" toward microscopic scales or higher-dimensional bulk spacetime, rather than physical expansion throughout the universe. Extending Smart’s "transcension hypothesis" within the framework of theoretical physics, this paper posits that the limits of large-scale, fault-tolerant quantum computation serve as an engineering interface for manipulating higher-dimensional spacetime metrics—mediated by DBI/WZW effective actions and the ER=EPR conjecture. Furthermore, a three-tiered hierarchical model of precursor civilizations is formulated, corresponding to the degrees of freedom within extra dimensions (such as bulk metrics, the moduli space of Calabi-Yau manifolds, and the M-theory landscape); this model presents a game-theoretic equilibrium for high-dimensional security, centered on the prevention of false-vacuum decay. Finally, to ensure the falsifiability essential to scientific theory, four observable "technosignatures" are proposed—complete with quantitative order-of-magnitude estimates—ranging from gravitational-wave leakage from warped extra dimensions (in the MHz–GHz frequency range) to the asymptotic complexity thresholds of quantum processors driven by bulk back-reaction.
