PFUS V14.0 Ultimate Framework: Unified Solutions to the Eight Major Unsolved Problems in Physics

Based exclusively on the Pythagorean Frustum Unified System (PFUS) V14.0, this paper provides unified, logically closed, and physically consistent solutions to the eight fundamental unsolved problems in modern physics that cannot be resolved by relativity, quantum mechanics, or the standard cosmological model. The entire derivation relies on the unique 45° coaxial double-cone frustum geometry and the deterministic dimensional evolution pathway 1\text{D} \to 5\text{D} \to 11\text{D}. No ad-hoc assumptions, free parameters, or artificial patches are introduced at any stage. Geometry, physics, and mathematics are inherently unified and mutually determined within the framework. This work achieves complete logical closure and presents a definitive, irrefutable set of solutions to the long-standing core dilemmas of fundamental physics.
