(Conceptual Synthesis) Global Complexity Stability Theory (GCST) proposes a universal stability law governing the evolution of complex systems across scales—from biospheres and civilizations to galaxies and the Universe. The theory introduces a dimensionless stability parameter G = γ/(αC) and predicts limits on complexity growth, phase transitions, and collapse thresholds in accelerating systems.

(Conceptual Synthesis) Abstract Global Complexity Stability Theory (GCST) proposes that the stability of any complex system is determined by the balance between three fundamental quantities: structural complexity C, rate of environmental change α, and recovery/stabilization rate γ. The theory asserts that instability emerges primarily from acceleration: when α exceeds a critical threshold relative to γ/C, the system accumulates instability debt, leading to bifurcations, multistability, and potential collapse.
