Primordial black holes, cosmological dark matter, and galactic antimatter

It is argued that the dense population of the early universe with well developed galaxies and supermassive black holes (quasars), observed by HST and JWST, nicely fits the conjecture that the galaxies and quasars are seeded by primordial black holes (PBHs), proposed in our work more than 30 years ago. This idea of galaxy seeding by massive black holes is rediscovered in recent publications by several groups. It is shown that the predicted log-normal mass spectrum of PBHs very well agrees with astronomical observations.
