Beyond Lunar Gravity: A Unified DGST Model for Ocean Tides via Atmospheric Shield Pressure (D = 8.55), 1°Axial Tilt (60'), and Rotational Geometry

Challenging the classical paradigm attributing oceanic tides to lunar gravitational attraction, this paper presents a non-gravitational hydrodynamic model governed by the Deshmukh Global Shield Theory (DGST). We establish that ocean tides are generated by Earth's atmospheric pressure shield (D = 8.55) interacting with a daily axial tilt displacement (60' arcminutes) and ocean basin dynamics. The shield factor D = 8.55 regulates Earth's equatorial velocity at 1,670 km/h, yielding a rotational geometric ratio of 3.1455 when comparing 24-hour boundary progression (40,080 km) against mean diameter (12,742 km). Factoring in the $1^\circ$ tilt shift, the resulting hydraulic pressure release delay is calculated at 47.1 5min 42.1 to 52.1{ minutes}, accounting for the daily tidal progression through pure rotational hydrodynamics.
