E = (G − T)c² Cosmology of the Dynamic Transformation of the Universe

Title: E=(G−T)c2 — The Cosmology of Dynamic Change of the Universe (DCU) Abstract This paper presents the Dynamic Change of the Universe (DCU) — an original, quantitative cosmological theory that offers a unified alternative to the standard ΛCDM model, thereby solving the singularity problem and the ontological puzzles of the dark sector. Fundamental Axiom and Formalism: The DCU model establishes the Universe as a dynamic balance between gravitational convergence (G) and the expansive tension of the vacuum (T), defining the effective energy of the Universe as the residual tension: E=∣G−T∣c2 The entirety of the Universe's dynamics arises from a single, unitary field (the so-called "null string" or DM-field). Mathematically, the model is described by a nonlinear k-essence Lagrangian of the form Lϕ=M4[c1X+c2X2]−V0, where the nonlinear term c2 is crucial for the self-regulation of the system. Key Solutions and Achievements: Singularity Resolution: The kinetic nonlinearity (the c2 term) ensures the condition cs2>0, enabling a stable, non-singular cosmic "bounce" instead of the classical Big Bang, thereby preserving information unitarity. Dark Sector Unification: DM, EDE, and DE are treated as different kinetic and potential phases of the same DM-field, thus resolving the coincidence problem. Resolution of Empirical Tensions: The DCU model naturally predicts observational consequences consistent with current tensions, including an elevated local H0 value and reduced structure growth (σ8), which is explained by the EDE-phase of the DM-field. Philosophical Inherence: The model presents the "Full Circle Logic" (a cyclic, self-balancing Universe) wherein DE is a manifestation of the Cosmological Membrane's tension, and c2 represents the elasticity of space itself. The author introduces the epistemological framework of the "win–win singularity loop" as evidence of the hypothesis's irrefutable symmetry, where every experimental confirmation or refutation (unless c2 is proven impossible) leads to the same conclusion: that the Universe is cyclic and unitary. The paper calls for rigorous numerical testing of the parameter c2 for its falsification.标题：E=(G−T)c² — 宇宙动态变化理论（Dynamic Change of the Universe, DCU） 摘要：本文提出宇宙动态变化理论（Dynamic Change of the Universe, DCU）——一种原创性定量宇宙学理论，可作为标准ΛCDM模型的统一替代方案，由此解决了奇点问题（singularity problem）与暗扇区的本体论难题。 基本公理与形式体系： DCU理论将宇宙定义为引力收敛（G）与真空膨胀张力（T）之间的动态平衡，并将宇宙有效能量定义为剩余张力： E=|G-T|c² 宇宙的全部动力学均源自单一统一场（即所谓的"零弦"或暗物质场（DM-field））。在数学层面，该模型由形如$L_phi = M^4[c_1X + c_2X^2] - V_0$的非线性k-本质（k-essence）拉格朗日量描述，其中非线性项$c_2$是系统自调节的关键。 核心结论与成果： 奇点解决方案：动力学非线性项（即$c_2$项）保证了声速平方$c_s^2>0$的条件，使得宇宙能够实现稳定的、非奇点的"反弹"，而非经典的大爆炸，由此保留了信息幺正性（unitarity）。 暗扇区统一：暗物质（DM）、早期暗能量（EDE）与暗能量（DE）被视为同一暗物质场的不同动力学与势能相态，由此解决了巧合问题（coincidence problem）。 经验张力解决：DCU理论可自然预言与当前观测张力相符的观测结果，包括偏高的本地哈勃常数（$H_0$）数值与降低的结构增长因子（$sigma_8$），这些均可通过暗物质场的EDE相态得到解释。 哲学内涵：该理论提出了"全循环逻辑"（即循环、自平衡的宇宙），其中暗能量是宇宙膜张力的体现，而$c_2$则代表空间本身的弹性。 作者提出了"双赢奇点循环"的认识论框架，作为该假说具有不可辩驳对称性的证据：无论实验验证还是证伪（除非$c_2$被证明不可能存在），最终都将指向同一结论——宇宙是循环且幺正的。本文呼吁对参数$c_2$开展严格的数值检验以完成证伪。
