An Ontological Reformulation of Gravitation: The Intrinsic Proximity Framework

Abstract This paper proposes an ontological system of intrinsic gravitational approach. While retaining the mathematical form of classical gravitational formulas, it rejects the geometrical ontological interpretation that "spacetime curvature constitutes the essence of gravitation". Taking flat spacetime as the background framework, it reconstructs gravitation as a local coupling effect between mass-energy bodies and substantial gravitational fields, which is essentially the macroscopic manifestation of the intrinsic mutual-approach property inherent in mass-energy bodies. Taking three core postulates as the sole logical starting point, the system derives five fundamental theorems and a two-tier quantitative rule system without any additional ad hoc assumptions, forming a self-consistent axiomatic theoretical framework. The system establishes the core mechanism of "dynamic coupling strength": a universal response function G_eff(E_g, v_rel, P) is defined, with the Local Laboratory Reference Response Point (LLRP) serving as the unified quantitative benchmark anchor for the entire system. This function simultaneously modulates two categories of observational effects at the same spacetime point: macroscopic dynamic effects including celestial orbit evolution and Mercury's perihelion precession, and microscopic periodic effects including gravitational time dilation and gravitational redshift. The two are not independent physical mechanisms, but parallel manifestations of the same coupling strength across different observational dimensions. A full spectrum of classical gravitational phenomena—Mercury's perihelion precession, gravitational deflection of light, gravitational lensing, Shapiro delay, and black hole shadow—can be uniformly traced to the local modulation of this response function and its integral accumulation along the motion path. This system embeds the weak equivalence principle into the unitary ontology of mass-energy, clarifying that gravitational mass and inertial mass are two facets of the same mass-energy ontology under the "active field source" and "passive response" modes, thus requiring no presupposition as an independent axiom. It further specifies the effective range of the weak equivalence principle based on a mass ratio criterion. In strict adherence to the principle of mathematical equivalence, the system maintains full compatibility with the verified quantitative conclusions of Newtonian mechanics and general relativity under the quasi-static approximation of weak fields and low velocities. Meanwhile, it puts forward testable differentiated inferences for strong-field scenarios: the black hole event horizon is a critical isosurface of coupling strength, and no spacetime singularity exists at the center—only a dense matter core supported by finite mass-energy. The theoretical framework construction and qualitative deduction of this work are currently completed. Tasks including calibration of the universal response function form, quantitative calculation of strong-field dynamics, matching of gravitational wave waveforms, experimental verification of the dynamic gravitational constant, and testing of the weak equivalence principle's effective range are designated as open collaborative tasks, providing an expandable alternative research path for fundamental ontological studies of gravitation. 摘要 本文提出引力内禀趋近本体论体系,在沿用经典公式数学形式的基础上,摒弃“时空弯曲为引力本质”的几何化本体诠释,以平直时空为背景舞台,将引力重构为质能体与实体引力场之间的局域耦合效应,本质是质能体内禀相互趋近属性的宏观显化。本体系以三条核心公设为唯一推演起点,逻辑导出五条基础定理与双层量化规则,全程无额外特设假设,构建了自洽的公理化理论框架。 体系确立“动态耦合强度”核心机制:定义普适响应函数G_eff(E_g, v_rel, P),并以局域实验室参考响应点(LLRP)为全体系统一量化基准锚点;该函数在同一时空点同步调制两类观测效应:一是宏观动力学效应,涵盖天体轨道演化、水星近日点进动等现象;二是微观周期性效应,涵盖引力时间膨胀、引力红移等现象。二者并非独立物理机制,而是同一耦合强度在不同观测维度的并行显现;水星进动、光线引力偏折、引力透镜、夏皮罗延迟、黑洞阴影等全系列经典引力效应,均可统一溯源至该响应函数的局域调制与沿运动路径的积分累积。 本体系将弱等效原理内嵌于质能单一本体,明确引力质量与惯性质量是同一质能本体在“主动场源”与“被动响应”两种模式下的一体两面,无需作为独立公理预设,并进一步给出基于质量比判据的弱等效原理有效作用区间。全文严格遵循数学等效原则,在弱场低速准静态近似下,与牛顿力学及广义相对论已验证的定量结论保持严格兼容;同时在强场场景下作出可检验的差异化推论:黑洞视界为耦合强度的临界等值面,中心不存在时空奇点,仅存在由有限质能支撑的致密物质核心。 本文当前已完成理论框架搭建与定性推演,将普适响应函数的形式标定、强场动力学定量计算、引力波波形对接、引力常数动态化实验验证及弱等效原理有效域检验列为开放协作任务,为引力物理的基础本体论研究提供了可拓展的替代研究路径。
