Cosmological Physics Thought Experiment: Causality Softening, Cosmic Contraction, and Gravitational-Wave Inelasticity / 宇宙物理思想实验:因果律软化、宇宙收缩与引力波非弹性

Full bilingual text and framework available at self-as-an-end.net An independent thought experiment exploring the physical implications of causality softening within the SAE framework. The paper proposes that causality (understood as 4DD's suppression of lower-layer remainders) is not absolutely rigid, and that the universe's evolution should contain an accumulable residual interface through which suppressive capacity loosens over time. Key conjectures include: (1) the total cosmic lifespan is approximately 20 billion years, with 5DD (life) at the midpoint; (2) cosmic contraction is the physical expression of causality softening; (3) gravitational-wave inelasticity — irreversible micro-deformations of spacetime after gravitational waves pass — as a candidate physical mechanism, related to but not equivalent to the known gravitational-wave memory effect (Christodoulou 1991, Thorne 1992); (4) nonlinear positive-feedback accumulation of softening, implying that posterior models systematically overestimate cosmic lifespan; (5) LISA as a possible indirect falsification pathway via non-Gaussian statistics in the gravitational-wave background. An appendix addresses the unresolved tension between the 20-billion-year symmetry assumption and nonlinear acceleration. All conjectures have remainder and are open to falsification. Bilingual: Chinese as authoritative text, English as rewrite. Firewall: this paper is standalone; any falsification does not affect other SAE papers.
