A Python simulation of a cyclic universe with gravity (G), dark energy (Λ), quantum bounce (Q), and negative mass (-M). After an automated parameter search (139 runs), the model shows agreement with four independent observational tests: First peaks of the Planck CMB spectrum. Large-scale structure (filaments, voids) from SDSS. Galaxy cluster distribution (MCXC-II). Gamma-ray dipole anomaly (l=176. 9°, b=-7. 3°). The optimal parameters are: G=0. 095, Λ=0. 05, Q=0. 0103, -M=5%, fluctᵣate=0. 005. The author thanks DeepSeek for assistance in code development, discussions of physical ideas, and support throughout the research.
