s8-tension

🌌 Modular Substrate Theory (MST): Resolves the H₀ & S₈ cosmological tensions via informational friction. Based on the discrete ℤ₆⁽¹⁾ vacuum symmetry, it derives cosmic impedance from first principles. Repo includes the manuscript, Bayesian validation (ΔBIC=-12.1), & reproducible Jupyter notebooks. 🔭

5D Gauss-Bonnet braneworld solution with holographic transfer function. First-principles derivation complete; observational test shows S₈/Lyman-α incompatibility. Falsification analysis published.

Python implementation of Topological Entropic Gravity (Hughes 2025) for solving S8 tension.

Private browser-based lab modeling tomographic cosmic-shear correlation functions (xi_plus) against survey-style KiDS/DES reference anchors, exploring sigma8/Omega_m/S8 and intrinsic-alignment sensitivity via a Web Worker.

Lightweight C/Python toolkit for astronomical N-body simulations. Reconciles SPARC rotation curves and JWST morphology via a 1.21e-10 m/s^2 threshold patch. 解決星系旋轉殘差、JWST 數據偏差及數值不穩定問題。

Zero-parameter framework resolving ΛCDM tensions via 45-channel decoherence in de Sitter 5D

Full likelihood cosmological comparison of ECTI-P vs ΛCDM using CLASS + Cobaya

Modified CLASS/Boltzmann pipeline for a screened conformal-scalar dark sector (the Dark Boson): scale-dependent growth suppression S(k), S8 = 0.78 (0.6-1.6 sigma from lensing), and a -3.5% sound-horizon shift raising early-time H0 to ~70 km/s/Mpc (4.8 -> 2.3 sigma). Fixed parameters, nothing fitted. Companion code to the Dark Geometry papers.
