A Systems-Level Hypothesis for Thermal and Structural Equilibrium in Galaxies

This paper proposes the hypothesis that supermassive black holes act as dynamic feedback regulators that contribute to the long-term thermal, pressure, and structural equilibrium of their host galaxies by redistributing energy through relativistic jets. The proposed framework builds upon established AGN feedback physics while offering a broader conceptual interpretation in which black hole feedback acts as part of a naturally self-regulating galactic system.
