Reconstructing the Entire Observable Universe From Physical Constants: A Full-Scale Cosmological Simulation Reveals a Hidden 55-Node Manifold

We present the first full forward-evolution simulation that reconstructs the observable universe using only real cosmological constants — no added particles, no assumptions, no speculative physics. Starting from post-recombination conditions (z ≈ 1100), the model reproduces cosmic-web structure, matter power spectra, halo formation, and CMB anisotropy decay with remarkable fidelity. Most strikingly, the system spontaneously generates a stable, zero-variance 55-node geometric manifold, identical to structures observed in independent simulations. This result suggests that dark-matter-like gravity may arise from shadow-density fields generated by fractional-dimensional curvature leakage, revealing a deeper geometric architecture beneath ΛCDM. This work may represent a new route to understanding dark matter, cosmic topology, and the geometric foundations of the universe.
