The Fluid Dynamic Origin of Mass: Occlusion Pressure Difference, Inertial Origin and Mach's Principle

Abstract Within the framework of the Standard Model of particle physics, particle mass is treated as an intrinsic property conferred by the Higgs mechanism. While mathematically self‑consistent, this mechanism does not clarify the underlying dynamical ontology of mass, nor can it provide a unified physical explanation for the inertia‑gravity equivalence and Mach’s principle, leaving long‑standing theoretical gaps concerning the origin of mass. Based on the FQ graviton‑fluid occlusion‑pressure unified‑field theory, this paper abandons the traditional presupposition that mass is an intrinsic property of matter. It proposes that mass arises from the occlusion‑interaction effect between the micro‑topology of matter and the universal graviton fluid. The physical origin of inertial mass is the momentum‑change cost of graviton fluid entrained within the effective occlusion volume of an object during acceleration; gravitational mass originates from the universal graviton‑fluid flux gradient produced by an object’s effective occlusion cross‑section. Taking the effective occlusion volume as the core physical quantity, this paper constructs hypothetical physical equations to illustrate the homologous equivalence between inertial mass and gravitational mass from a fluid‑dynamics perspective. A fluid‑mechanical interpretation of Mach’s principle is given: the mass‑inertia effect is an interaction relation among matter, the cosmic background medium, and all other matter in the universe, rather than an inherent label of an isolated particle. If a particle exhibits no effective occlusion interaction with the graviton fluid, no macroscopic mass effect will manifest. Relying on the background static‑pressure relation of the FQ framework, the mass‑energy equivalence relation E=mc_0^2 is derived from a fluid‑dynamics viewpoint. Combined with the hierarchical‑debinding mechanism from previous thermodynamics‑phase‑transition papers, the physical picture of mass defect in nuclear reactions is explained: mass represents the frozen potential energy of graviton fluid locked by micro‑topology; mass defect essentially corresponds to debinding of occlusion topology, where locked potential energy is converted into free kinetic energy of graviton fluid. 摘要 在粒子物理标准模型框架中,粒子质量被视作由希格斯机制赋予的内禀属性。该机制虽具备数学自洽性,却无法阐明质量对应的底层动力学本质,也不能对惯性‑引力等效原理、马赫原理给出统一物理解释,使得质量起源问题长期存在理论空白。本文基于FQ引力子流体遮挡压差统一场论,摒弃“质量为物质内禀固有属性”的传统预设,提出质量源于物质微观拓扑结构与全域引力子流体之间的遮挡交互效应。惯性质量的物理本源,是物体发生加速运动时,其有效遮挡体积裹挟的引力子流体产生的动量变化代价;引力质量则由物体有效遮挡截面积形成的全域引力子流体通量梯度效应产生。本文以有效遮挡体积为核心物理量,构建假说物理方程,从流体动力学角度阐明惯性质量与引力质量的同源等效机制,给出马赫原理的流体力学诠释:质量‑惯性效应是物质、宇宙背景介质与宇宙其余物质相互作用的关联效应,并非孤立粒子的固有属性。若粒子不与引力子流体产生有效遮挡交互,则不会呈现宏观质量效应。依托FQ体系本底静压关系,本文从流体动力学视角推导质能等价关系E=mc_0^2;结合本系列热运动与相变层级解绑机制,阐释核反应质量亏损的微观物理本质:质量是微观拓扑锁存的引力子流体冻结势能,质量亏损本质为遮挡拓扑解绑,锁存的静态势能转化为引力子流体自由动能。
