Space-Geometry Cyclic Universe: A Thought Experiment — Unifying Dark Energy, Dark Matter, Inflation, and the Four Fundamental Forces with Three Axioms (Revised Thought‑Experiment Version)

We present a conceptual framework based on three axioms: (1) spatial ontological monism, (2) strict global zero‑energy balance, and (3) eternal closed cyclic evolution. The only fundamental reality is three‑dimensional continuous space. Dark energy, dark matter, the inflaton field, and the four fundamental forces are not independent entities but manifestations of local topological folds and intrinsic deformations of space itself. We introduce a new scalar field Ψ, called spatial autodynamicity, which measures the deviation of space from an intrinsic reference configuration. The self‑adaptive potential ½μ²Ψ² drives cosmic acceleration (dark energy), while topological defects of Ψ (kinks, vortices, trefoil knots, chiral twists) correspond to dark matter and the gauge fields of the Standard Model. The universe undergoes eternal cycles: bounce → expansion → heat death → contraction → mirror bounce, with a full cycle of about 250 billion years. Thermal entropy resets at each bounce; geometric entropy (large‑scale Ψ modes) is preserved via CPT mirror symmetry, explaining CMB low‑ℓ anomalies. Time is derived from the evolution of Ψ. The framework yields falsifiable predictions: r ≈ 0. 0012 (CMB‑S4), a declining dark energy equation of state (w₀ ≈ –0. 96, wₐ ≈ –0. 15), an ultra‑low‑frequency gravitational wave background (hc ∼ 10⁻²² for SKA‑PTA), and null results for all particle dark matter searches. This is a thought experiment, not a standard physics paper; the author is not a physicist, and AI tools were used for language assistance. Collaboration is welcome.
