A New Mechanism for Celestial Evolution: A Unified Model of Iron-Nickel Core Aggregation and Gravitational Activation

Traditional celestial formation theories are based on gravitational collapse and random density fluctuations, which fail to explain three key observational facts: 1. Why massive galaxies formed rapidly in the extreme early universe; 2. Why terrestrial planets universally possess high-density iron cores with abundances far exceeding the average of the nebula; 3. How diffuse hydrogen-helium nebulae break through thermal motion barriers to achieve ordered collapse. This paper proposes the iron-nickel core coalescence hypothesis and establishes a unified physical model from microscopic magnetic interactions to macroscopic gravitational evolution: 1. Nucleation stage: Ferromagnetic elements such as iron and nickel in the nebula aggregate preferentially via intrinsic magnetic moments and directional Field Energy Aggregation Force (FEAF), forming a dense and stable solid core, which is a necessary prerequisite for celestial formation and the only way to break through thermal motion resistance; 2. Activation stage: When the core mass and density exceed critical thresholds, FEAF undergoes a phase transition from "ferromagnetic selective attraction" to "global broad-spectrum attraction", i.e., macroscopic gravity is activated; 3. Growth stage: After gravitational activation, the celestial body enters a mass-accretion positive feedback cycle and collapses rapidly into a spherical structure. This model unifies the permanent magnetic order and gravitational field in celestial evolution for the first time. It not only provides a quantitative explanatory framework for a series of key observations including the rapid formation of early galaxies, the origin of planetary iron cores, the spherical geometry of celestial bodies, and the lower limit of stellar iron abundance, but also establishes a unified evolutionary paradigm for planet and star formation. This study provides a brand-new underlying logic for astrophysical research and theoretical support for relevant engineering applications. 摘要 传统天体形成理论以引力坍缩与随机密度涨落为基础,难以解释三大关键观测事实:1. 宇宙极早期为何能快速形成大质量星系;2. 类地行星为何普遍拥有远超星云平均丰度的高密度铁核;3. 弥散氢氦星云如何突破热运动壁垒实现有序坍缩。 本文提出铁镍核心抱团假说,建立一套从微观磁相互作用到宏观引力演化的统一物理模型:1. 成核阶段:星云中铁、镍等铁磁元素通过固有磁矩与定向场能聚合力(FEAF)优先成团,形成致密、稳定的固态核心,这是天体形成的必要前提,也是突破热运动阻力的唯一途径;2. 激活阶段:当核心质量与密度突破临界阈值,场能聚合力从“铁磁选择性吸引”相变为“全域广谱吸引”,即宏观引力被激活;3. 增长阶段:引力激活后,天体进入质量—吸积正反馈循环,并快速坍缩为球状结构。 该模型首次将永磁序与引力场在天体演化中统一起来,不仅为早期星系快速形成、行星铁核起源、天体球状几何、恒星铁丰度下限等一系列关键观测提供了定量解释框架,更建立了行星与恒星形成的统一演化范式。本文研究为天体物理研究提供了全新的底层逻辑,也为相关工程应用提供了理论支撑。
