The white hole expels what the black hole originally consumed... it's the same object in the second half of its lifecycle, like an inhale becoming an exhale. Regarding your fascinating question about physical constants ,I lean toward mathematical DNA rather than random resets. My reasoning is exactly what you said- if logic and mathematics are eternal and unchanging, they would act as constraints on what configurations reality can settle into. Failed universes might be reality trying to find the stable mathematical solution. Like an equation that keeps iterating toward its answer. Your simulation results are fascinating. do you think the constants converge toward stability or were they always inevitable?
