A Cyclic Universe Model with Negative Mass: 7 Observational Confirmations

I present a cyclic universe model incorporating negative mass (-M). The model replaces the Big Bang singularity with a quantum bounce, solves the entropy problem through cycle-induced reset, and preserves information across cycles via negative mass. Negative mass explains dark matter. The nature of dark energy remains a hypothesis at this stage: it is suggested to be a fundamental property of spacetime itself (mathematical development of this idea is left for future work). The model successfully passes 7 independent observational tests: Planck CMB power spectrum, SDSS large-scale structure, MCXC galaxy cluster distribution, Fermi gamma-ray dipole anisotropy, BAO scale from SDSS/DESI, Type Ia supernovae (Pantheon+/Union2.1), and the Hubble constant H0 = 79.93 ± 2.74 km/s/Mpc. This represents the first observationally validated negative mass cosmology, addressing critical issues raised in previous work (Farnes 2018; Socas-Navarro 2019). The model also resolves 13 fundamental problems in standard cosmology while maintaining minimal assumptions. All code and data are publicly available on GitHub.
