[MST-EUT Theory Series #16] Fixed-Point Derivation of Vacuum Electromagnetic Constants from Critical Entropic Field — 從臨界熵場到真空電磁常數的固定點推導 (v1.1-zh)

This document presents a fixed-point derivation framework for the vacuum electromagnetic constants μ₀ and ε₀ within the Mass–Space–Time Entanglement Unified Theory (MST–EUT). By introducing a critical entropic field density and a self-consistent response function g(ρ), the vacuum constants are interpreted as emergent fixed-point quantities rather than fundamental inputs. The results reproduce the correct experimental order of magnitude and establish a foundation for subsequent derivations of electromagnetic and relativistic constants. 本文為 MST–EUT 理論系列第十六份文件,提出一種基於臨界熵場密度與固定點機制的真空電磁常數推導架構。透過引入熵場回應函數 g(ρ),將 μ₀ 與 ε₀ 詮釋為自洽的場論固定點量,而非先驗定義常數。結果在量級上與實驗值一致,並為後續電磁與相對論常數的第一性原理推導奠定基礎。
