Redefining Celestial Seasons: A Comparative Analysis of Mainstream Axial Tilt Theory and the Deshmukh Global Shield Theory (DGST)

Mainstream astrophysics attributes the phenomenon of planetary seasons solely to a body’s axial tilt and the resulting geometric variation in solar radiation angles. This paper challenges this conventional framework through the paradigm of the Deshmukh Global Shield Theory (DGST). DGST posits that true seasons are not merely dead, physical temperature contrasts, but are self-regulating biological and atmospheric cycles engineered to sustain life. By analyzing the astronomical profiles of planets like Mars (which possesses a similar axial tilt to Earth but lacks hydrological cycles) and Uranus (which exhibits extreme tilt but experiences static climatic phases), this study demonstrates that axial tilt alone is insufficient to generate seasons. Instead, DGST introduces the mechanism of the Earth’s 'Global Shield' (the Atmospheric Ozone Layer / Cosmic Womb), which acts as a mechanical filter and pressure regulator. This shield absorbs raw universal light, solar winds, and external planetary pressures, transforming harsh cosmic binaries into nurturing cyclical rhythms (such as rainfall and pressure zones) essential for the biosphere.
