Empirical Validation of the Metric Pressure Constant κ in the Neutrino Metric Model (NMM / Λ–κ Framework)

This dataset presents the first empirical validation of the Neutrino Metric Model (NMM – Λ–κ Framework), a cosmological extension describing gravity as an emergent pressure of the neutrino field. The analysis of 175 SPARC galaxies demonstrates the universality of the metric constant κ ≈ 1.0×10²⁶ m³/kg, confirming consistency between local dynamics and cosmological Λ calibration.本数据集首次完成了中微子度规模型（Neutrino Metric Model，NMM——Λ-κ框架）的实验验证，该模型是一类将引力描述为中微子场涌现压强的宇宙学推广理论。通过对175个SPARC星系的分析，研究证实了度规常数κ≈1.0×10²⁶ m³/kg的普适性，验证了局域动力学与宇宙学Λ校准之间的一致性。
