Abstract: The 5σ tension in the Hubble constant (H0) between the SH0ES team’s value of approximately 73 km/s/Mpc and the Planck satellite’s inferred value of approximately 67 km/s/Mpc is conventionally interpreted as either systematic measurement error or evidence for new physics. Drawing upon the core logic of Constitutive Spacetime Dynamics (CSSD), this paper demonstrates that this tension is neither error nor anomaly, but rather a precise record of the constitutive response of the substantival spacetime lattice across different evolutionary stages. We first introduce a mechanism of "synchronized speed-of-light doubling" to explain primordial inflation: not as superluminal expansion, but as a cascade of synchronized doublings of the lattice units’ intrinsic response frequency, mathematically expressed as ceff = 2ⁿ * c0. This resolves the scale problem at the time of CMB emission without invoking superluminal expansion. We then demonstrate that the early-universe measurement H0 ≈ 67. 4 km/s/Mpc represents the "loaded" response frequency, where constitutive energy is massively allocated to particle authentication and structure formation. Following the completion of large-scale structure assembly approximately 6 billion years ago, this construction energy is released back into the expansion sector, driving the observed transition to H0 ≈ 73 km/s/Mpc. We further prove that the fluctuations prior to 6 billion years are normal manifestations of the construction-era energy budget, while the subsequent stabilization is the necessary consequence of constitutive saturation. The value 73 km/s/Mpc is not a "repulsive force" measurement but the constitutive saturation frequency of the substantival spacetime lattice under zero load—the factory frequency (intrinsic eigenfrequency of the lattice substrate) and physical speed limiter of the cosmos. Recent observations (DESI 2024, Lee et al. 2025) revealing "late-time deceleration signals" are perfectly explained within the CSSD framework as the return to constitutive equilibrium. This finding fundamentally excludes the logical possibility of a "Big Rip. " This work further serves as a definitive synthesis of the CSSD series (I–XVIII), a framework rigorously validated by gravitational-wave empirical data (|β| < 9 × 10^-23). By restoring the substantival attributes of the spacetime lattice and the "time bus" logic, this model demonstrates that cosmic expansion has never exceeded the speed of light. It systematically resolves a constellation of enigmas: 1) Inflation as lattice-step frequency transitions; 2) Dark Matter as non-linear lattice response (Cui Constant Cc ≈ 5) ; 3) Dark Energy as the release of construction-era bandwidth; 4) The "Axis of Evil" as the initial topological orientation of the lattice; 5) The "Cold Spot" as a constitutive defect; and 6) Hoag-type objects as topological standing waves. Under CSSD, the universe shifts from a "tug-of-war" of dark shadows to a transparent "energy ledger. " The anomaly is the truth; the tension is the evolution. 摘要 SH0ES团队测得的约73 km/s/Mpc与普朗克卫星推导的约67 km/s/Mpc之间的5σ哈勃张力, 传统上被解释为测量误差或新物理证据。基于实体时空动力学 (CSSD) 的核心逻辑, 本文证明该张力既非误差也非异常, 而是实体时空点阵在不同演化阶段本构响应的精确记录。 我们首先引入“同步光速翻倍”机制来解释原初暴涨: 它并非空间的超光速膨胀, 而是点阵单元固有响应频率 (时间总线步频) 的同步级联翻倍 (ceff = 2ⁿ * c0) 。这在不违背因果律的前提下解决了CMB时期的尺度难题。研究表明, 早期宇宙的67. 4 km/s/Mpc代表了点阵在物质确权与结构形成高峰期的“带载”响应频率;随着约60亿年前大尺度结构完工, 建造能释放回膨胀扇区, 驱动了向73 km/s/Mpc的转变。73 km/s/Mpc并非斥力测量值, 而是实体时空点阵在零负载下的本构饱和频率——即宇宙的“出厂主频”与物理限速器。近期观测 (DESI 2024, Lee et al. 2025) 发现的“晚期减速信号”在CSSD框架下得到了完美解释, 即向本构平衡的回归, 这从逻辑上排除了“大撕裂”的可能性。 作为CSSD系列 (I-XVIII) 的总纲, 本项目得到了引力波实测数据 (|β| < 9 × 10^-23) 的严密验证。通过还原时空点阵的实体属性与时间总线逻辑, 本模型证明宇宙膨胀从未超越光速, 并系统性地解决了系列难题: 1) 暴涨即点阵步频跃迁;2) 暗物质即非线性本构响应 (崔氏常数Cc ≈ 5) ;3) 暗能量即建造带宽释放;4) “邪恶轴线”即点阵初始拓扑取向;5) “冷斑点”即早期本构缺陷;6) 霍格天体即拓扑驻波。在CSSD框架下, 宇宙从暗影的“拔河”转向了透明的“能量对账单”: 异常即真相, 张力即演化。 Keywords Hubble Tension, Constitutive Spacetime Dynamics (CSSD), Construction Energy, Bandwidth Release, Constitutive Saturation, Existence Debt, Cui Constant, Synchronized Speed-of-Light Doubling, Construction Era, Operation Era, Axis of Evil, Cold Spot, Time Bus. 主题词 哈勃张力, 实体时空动力学 (CSSD), 建造能, 带宽释放, 本构饱和, 存在债务, 崔氏常数, 同步光速翻倍, 建造期, 运营期, 邪恶轴线, 冷斑点, 时间总线。
