Resonant Selection and Existence Threshold Bands Structural Elimination and Survivability within Existence-Quantized Geometric Theory

Physical theory permits an enormous space of conceivable configurations, yet only a limited subset is ever realized in nature. This discrepancy is commonly addressed through empirical stability criteria or effective selection rules, often without a unified structural explanation.

This paper introduces the concept of resonant selection within the framework of Existence-Quantized Geometric Theory (EQGT). Rather than treating resonance as a stabilizing phenomenon, the analysis demonstrates that structural resonance with background or internal phase modes acts as a destabilizing mechanism, leading to rapid elimination of incompatible configurations.

The elimination of resonant structures partitions the space of possible configurations into discrete existence threshold bands, within which non-resonant structures persist and outside of which formation or long-term survival is impossible. This framework provides a structural basis for elemental stability limits, bounded complexity, and prime-like survivability patterns without invoking additional forces or probabilistic exclusion rules.

Resonant selection is shown to operate consistently across nuclear, atomic, and cosmological scales, offering a unified explanation for why observable reality occupies only a constrained subset of theoretical possibility, while remaining compatible with existing stability descriptions as effective observer-limited formulations.
