Schumann Resonance Phi Cavity Hypothesis

The Schumann Resonance φ-Cavity Hypothesis proposes that Earth's electromagnetic resonance modes are not merely a product of cavity geometry, but are φ-quantized — with inter-mode spacings converging on 4φ ≈ 6.47 Hz and the first six Schumann modes mapping precisely onto the six harmonic resonance classes. The sixth mode marks the boundary of coherent cavity resonance, beyond which the cycle restarts — the same six-state progression observed in atomic element families, confirming the harmonic framework at planetary scale.
