Anti-matter from the abyss per Planck time
We show a possible pathway to produce anti-matter particles in the ergo-region around a rapidly spinning black hole, where the charged particle densities are derived from the observed magnetic fields: The ergo-region contains a large fraction of antiprotons as well as anti-neutrons. So a standard chain of reactions known from the big-bang can produce both anti-3He as well as anti-4He. There should be a measurable quantity of anti-d, also of anti-t. Matching the observed magnetic fields in their transport of angular momentum outwards gives the Planck time for the transfer of particles into the black hole to reduce its angular momentum, for negligible accretion, and so also for the production of antimatter. Finding the Planck time via an interpretation of quantitative observations implies a small step towards combining quantum mechanics and gravity.
