[MST-EUT Theory Series #12] From Classical Limit to General Relativity - MST-EUT經典極限到廣義相對論 (v2.2-zh)

This document establishes the classical and relativistic limits of the Mass–Space–Time Entanglement Unified Theory (MST–EUT). Starting from the full entropic-flow-based field equations, we systematically derive the Newtonian limit and recover Einstein’s field equations in the appropriate weak-field and low-velocity regimes. The analysis clarifies how classical gravity, relativistic spacetime curvature, and effective force laws emerge as limiting behaviors of closed entropic flow configurations, rather than independent postulates. This work provides a consistency bridge between MST–EUT and established classical and relativistic physics, ensuring continuity with known experimental regimes. 本文為 MST-EUT 理論系列第十二份文檔,系統性建立 MST-EUT 由完整熵流場方程通往經典力學與廣義相對論的極限推導。從全域熵流封閉結構出發,本文推導牛頓極限,並在弱場、低速條件下回復 Einstein 場方程,說明經典重力、相對論時空曲率與有效作用力並非獨立假設,而是熵流拓撲構型的極限行為。本工作確立 MST-EUT 與既有經典與相對論物理之間的理論連續性,對應現有實驗尺度。
