Scientific Dossier: Metric Tension Adjustment Model (MATM) – Part IV (Unified Edition).

Abstract: This dataset presents the Metric Tension Adjustment Model (MATM) v4.2.0 – Unified Edition, a continuous media physics framework applied to cosmological spacetime. This version formally introduces the concepts of Metric Viscosity ($\eta$) and Flow Anisotropy as mechanical alternatives to Dark Matter and Dark Energy. Key contributions of this dossier include: Cosmological Maturity: Mathematical proof, supported by the included maturity_flow_v420.py script, that the universe has processed 99.92% of its primordial tension, evolving from an initial potential of 80.0470 to the current 0.0673. Resolution of the Hubble Tension: Demonstration that Relaxation Anisotropy allows cosmic voids and massive clusters to relax at different rates, resolving discrepancies in $H_0$ measurements. The "Soft Landing" Protocol: A non-linear asymptotic decay model for the Gravitational Constant ($G$), explaining the apparent stability in contemporary Lunar Laser Ranging (LLR) data while accounting for higher gravitational stiffness in the early universe. Metric Hysteresis: A mechanical explanation for the mass separation observed in the Bullet Cluster (Chandra), eliminating the need for non-baryonic dark matter particles. Quantum-Metric Link: Introduction of the Scale Identity coefficient ($\chi$), bridging the gap between Planck-scale mechanics and the Hubble Radius expansion. Included Files: Dossier_MATM_v4.2.0_Unified_Edition.pdf: Full theoretical documentation and references (APA 7th Ed). README.txt: Technical guide for simulation execution. Python Suite: Three validated scripts (maturity_flow, asymptotic_G_decay, and unified_scale_identity) providing the computational evidence for the model's claims. This work proposes that the universe is a self-stabilizing system moving towards the Silence Geometry ($\Lambda_\infty = 0.0013$), where metric tension reaches perfect geometric equilibrium.

Dossier_MATM_v4.2.0_Unified_Edition.pdf：完整的理论文档与参考文献（采用APA 7版引用格式）。 2. README.txt：模拟程序运行的技术指南。 3. Python脚本套件：包含3个经过验证的脚本（maturity_flow、asymptotic_G_decay及unified_scale_identity），为该模型的核心论断提供计算佐证。 本研究提出，宇宙是一个自稳定系统，正朝着静默几何（Silence Geometry, $Lambda_infty = 0.0013$）演化，此时度规张力将达到完美的几何平衡。 作者：若昂·巴蒂斯塔·德·卡斯特罗（João Batista de Castro） ORCID：0000-0002-4104-9340 授权协议：MIT / 知识共享署名4.0（Creative Commons Attribution 4.0）
