AbstractDeparting from abstract gravitational models, this paper evaluates interplanetary interactionsthrough the framework of the Deshmukh Global Shield Theory (DGST), focusing onmechanical, photonic, and magnetic pressure grids. Historical data spanning over 500 yearsdemonstrates that whenever Sun, Mercury, Venus, and Earth align within a critical angularspectrum of 2. 5^ (a centennial cycle occurring every 100 to 150 years), a severemulti-directional compression is exerted on Earth's geomagnetic shield and molten core. Thispaper maps four major historical alignments and correlates them with documented globalseismic, volcanic, and climatic anomalies. 2. Core Scientific Postulates (DGST Model) 1. Solar Photonic Thrust: The Sun acts as a primary mechanical engine, continuouslypropagating a powerful radiation and photonic pressure wave through interplanetaryspace. 2. The Planetary Squeeze (Mechanical Scissor): Venus, due to its retrograde (clockwise) rotation, creates a massive opposing magnetic resistance loop. When swiftMercury and Earth line up perfectly with Venus, Earth gets trapped directly between twoconflicting forces. 3. The 2. 5^ Critical Squeeze Rule: Severe geodynamic shifts or sudden ozonedeformations are triggered only when the angular proximity of Mercury and Venusrelative to Earth falls below a threshold of 2^ ३base' (2. 5^).
