Mem-force Theory V7: A Qualitative Picture from Cosmic Origin to Matter Decay (Theoretical Manifesto)

Mem-force Theory (V1–V6) has established the core framework of gravity as a vacuum restoring force, providing explanations for galaxy rotation curves, the QCD glueball mass spectrum, dark energy evolution, strong-field black hole corrections, and multi-probe experimental predictions. This paper completes three key components of the theory, but does not attempt to offer rigorous mathematical derivations. Instead, it integrates them into a self-consistent narrative using qualitative pictures and explicit assumptions: (1) α = sin(π/8) as a geometric axiom, stating its hypothetical status and justification (numerical agreement, eightfold symmetric geometry, self-consistency test); (2) a qualitative interpretation of matter decay and entropy increase from the viewpoint of Mem-force Theory – decay as a transition of microscopic excited states toward the ground state driven by the vacuum restoring force (attractive phase), and entropy increase as the statistical outcome of many particles being pushed toward more probable microstates by the same force; (3) a singularity-free cosmic origin via vacuum phase transition – the universe emerges from a vacuum phase transition, undergoing inflation (repulsive phase) → radiation/matter domination (attractive phase) → dark-energy accelerated expansion (second repulsive phase), all driven by the density-dependent restoring force with α = sin(π/8). We explicitly acknowledge the current limitations: lack of a complete compatibility proof with general relativity and the Standard Model of particle physics, partly unrealistic precision of some predictions, and the absence of a computable power spectrum for inflation. Hence, this work is positioned as a theoretical manifesto and research vision, intended to stimulate discussion rather than serve as a definitive treatise. All core predictions are linked to next-generation facilities (SKA, Euclid, LISA, CEPC) and can be verified or falsified within the coming ten to twenty years.
