Official repository for the Modular Substrate Theory (MST). Unifying alpha, H0, e, and zeta(0) via a Z/6Z substrate. Featuring 110-digit precision audits, a 10^-14 exact derivation of the fine-structure constant, and the resolution of the Hubble tension.

This project estimates key cosmological parameters like the Hubble constant (H₀) and matter density (Ωₘ) using Type Ia supernova data. It involves distance modulus fitting, cosmological model calculations, and analysis of low-z and high-z supernova subsets.

This program classifies the universe as flat, open, or closed based on the matter density parameter (Ωₘ) and dark energy density parameter (ΩΛ). The user enters the Hubble constant, Ωₘ, and ΩΛ, and the program uses these to determine the universe’s geometry.
