This paper redefines universal gravitation, the fundamental force of the universe, not as a 'pulling attractive force' but as a 'compressive force' where the high-pressure Younggun Medium pushes into a low-pressure zone. Modern physics has attempted to explain the four fundamental forces of the universe (gravity, electromagnetic force, strong force, and weak force) through individual fields and mediating particles (Bosons). However, this paper proves that these four forces are actually derived from a single principle: the fluid dynamic pressure gradient of the 'Younggun Medium' that fills the space of the universe. To prove this, the geometric structure of the 'Yang-Jung Shell (12-hole-6-passage system)', the smallest unit of a nucleon, is presented, and the flow velocities (1.5 and 3.0) of protons and neutrons are dynamically derived through the mechanical principles of the Tesla valve and check valve. Furthermore, it mechanically identifies actual measured data without error, such as the reality of magnetic field lines, the mass difference between protons and neutrons, the binding energy of the strong force (Mass Defect), the half-life of beta decay, and the bond angle of the water (H2O) molecule (104.5 degrees). This paper presents a massive paradigm shift, replacing quantum mechanics—which relied on probability and hypotheses—with mechanical engineering dynamics governed by causality.
