Abstract摘要

I review the theory known as Milgromian dynamics (MOND) and the evidence for it across a huge range of scales (Arxiv: 2110.06936). The main lines of evidence I discuss are the rotation curves of galaxies, the dynamics of ellipticals, the Local Group satellite galaxy planes, galaxy bar pattern speeds, the El Gordo galaxy cluster collision, the KBC void and the related Hubble tension. I also provide a viable cosmological framework for MOND involving light sterile neutrinos with a mass of 11 eV/c^2 and the same total density as the cold dark matter in the ΛCDM standard cosmological paradigm. I use this to explain observations previously considered problematic for MOND like the cosmic microwave background radiation and the Bullet Cluster, and galaxy clusters more generally.
