In these new approaches should be also added the conditions under which involving baryons might enhance the magnetic energy to even higher values. The maximum unstable wavenumber simply shows a transition from higher to smaller values with increasing baryon loading. But quantum non-locality means that the quantum tunnelling responsible for baryogenesis generates a uniform density of baryons on large scales. This means that the baryons have essentially the same density on large scales everywhere in the universe. I have shown that this large number of photons to baryons is a consequence of imposing the wrong boundary conditions in the very early universe. Furthermore, the range of unstable wavenumbers is narrowest for an electron-positron plasma and becomes increasingly broader for increasing baryon loading, eventually extending to k = 0 for an electron-ion plasma. They are baryons containing no up or down quarks. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license.
