A Numerical Conjecture on Spacetime Stiffness: Bridging the Planck and Cosmological Scales

This registration permanently archives all supplementary materials associated with the paper titled "A Numerical Conjecture on Spacetime Stiffness: Bridging the Planck and Cosmological Scales" The registered materials include: 1. The complete manuscript in PDF format (including references and appendices). 2. Python scripts used for gravitational-wave data analysis and numerical estimation of spacetime stiffness K. 3. Datasets and plotting scripts supporting the figures and results presented in the paper. 4. A structured reference list with linked sources. These materials provide the computational and analytical foundation for the heuristic conjecture K^3 = ρ_P ρ_Λ^2, the derivation of unified expressions for G and Λ, and the empirical bound on K from GW150914 data. This is the initial registered version (v1.0), corresponding to the submitted manuscript, and is intended to ensure reproducibility, transparency, and long-term accessibility of the research
