Baryon Number

The current model of the origin of the universe requires a violation of baryon number conservation. Baryon number conservation requires a constant difference between matter and antimatter. However, a violation of baryon number conservation has never been experimentally found, although there are sufficient theories about it. A pulsating world and the "Theory of the Isentropic World" . Just, the pulsating world raises the question: Why should a black hole explode? Is there a reasonable reason?
My question:Does baryon number conservation make sense?
Without baryon number conservation, it would be possible to convert matter into energy. Theoretically, the conversion of ordinary matter into antimatter should not cost any energy in total, since both antimatter and ordinary matter have the same energy content.
Or the following example:
Cold iron is undoubtedly anergy. Likewise, cold antiiron is anergy. Combining the two creates radiation, or exergy. Anergy becomes exergy, as in a perpedal mobile of the second kind.
According to my theory, everything must be mortal, even a black hole. This is why the known models are incomplete. A black hole must therefore spit out the baryons in the form of neutrons or hydrogen. How could that be possible? It can emit photons.* Due to the strong redshift, these photons are very energetic, even if they are barely measurable from a distance. Photons also have momentum and can accelerate baryons. This presumably allows the baryons to leave the black hole. For the "Isentropic World Theory", maintaining an average baryon number is essential. A decrease would increase the global temperature. An increase would destroy energy.

Ludwig Resch

* Photons are pure energy. But the matter falling into the black hole has lost a large part of its potential energy. So there is not much pure energy left.
