Thanks for the long answer, the only thing I did not understand is the fact of the irrelevance of the iron matter, I thought that maybe if the matter decays with iron tunneling, a boltzmann brain or other things can no longer form
Over long enough timescales any interaction will reverse, and happen again, and so on. It’s just a question of what fraction of time is occupied in each state. Or so the theory goes, at least.
Yes, there is no proof that they cannot possibly happen. It is a thing that theoretically could happen in a sufficiently boring universe, and there is no way to know whether our universe is sufficiently boring (but my prior odds are very much against it).

therefore the matter which will perhaps decay into iron is not proof against the Boltzmann Brains hypothesis

what could happen to not make it boring?
could you explain to me why?
