From Stability Bounds to QEV: Spectral Structure, Information Capacity and Functional Unification

Previous studies within the Quantum Emergent Vacuum (QEV) framework proposed thatonly a bounded interval of vacuum fluctuations contributes physically to the effective vacuumenergy density. More recently, the concept of stability bounds has been introduced as a possibleorganizing principle underlying the emergence of stable physical reality.In this work, the vacuum is examined as a spectrally bounded system characterized by physi-cally motivated ultraviolet and infrared limits. Building upon earlier QEV studies, we investigatewhether such bounds naturally define a finite information capacity and whether this capacitymay play a role in the emergence of stable physical structures.The analysis explores a possible connection between spectral organization, information con-tent, and stability formation. Within this perspective, causality, energy organization, and ge-ometric organization are interpreted as successive layers of physical structure rather than in-dependent features of reality. This approach provides a framework in which the fundamentalconstants c, h, and G may be viewed as complementary stability conditions associated with anorganized vacuum.The present work does not attempt to derive the fundamental constants themselves. Instead,it investigates whether spectral bounds, finite information capacity, and stability formation canprovide a common conceptual basis linking vacuum structure, vacuum energy, and the QuantumEmergent Vacuum model. The resulting framework is intended as a step toward a more unifieddescription of vacuum organization and its observable consequences.
