G_3_04 Verified Modern Frameworks

G_3_04 — Schumann Resonance & Frequency Claims

Schumann resonances (~7.83 Hz fundamental) are Tier 1 atmospheric physics — experimentally verified electromagnetic standing waves in the Earth-ionosphere cavity (Schumann 1952, Balser & Wagner 1960). The numerical coinc

O_1_02 Verified Earth Anomalies

O_1_02 — Magnetosphere, Solar Activity, and Earth's Shield

Earth's magnetic field is an invisible shield that makes complex life on the surface possible — without it, solar wind would strip away the atmosphere and sterilize the planet, as happened to Mars ~3.8 billion years ago

O_1_03 — Geomagnetic Anomalies and Human Health Effects

Earth's geomagnetic field is not uniform — dramatic anomalies like the South Atlantic Anomaly (SAA) expose organisms and technology to increased radiation, while laboratory experiments have shown that weak magnetic field
