Physical inferences and all other human thought apparently originate in the physical universe. There have been recent photos published by the Atacama Telescope, that went out of business in 2022 ,that show the early universe as it appeared 13 billion years ago. That is interesting for numerous reasons.
One I find interesting is that matter and anti matter canceled themselves out after those properties first appeared from a probable singularity. CP invariance let a very small percent of matter survive the renormalization That mass is primarily what appears in the photos, raising the point that it should be possible to calculate from the observable Universe then how much matter and anti-matter was in the singularity.
Singularities are not all equal in size and gravitational power. Time occurs differently in singularity if it exists at all. That is good because time only started with the release of matter/antimatter from the singularity with hyperinflation. In reverse though, the fields that were unified early on before expansion needed yet to have gravity to keep the singularity together, and the gravity particles existing below the plank length (if at all) at a certain minimal size of contraction turned off when the Universe became smaller than gravity field mesh. If the Universe as a singularity at that point became smaller than the gravitational field that contained it, it might have escaped like water through a fish net.
Maybe an area like this is a region were physics and metaphysical questions coincide, for there are more vectors to consider than may be addressed with arbitrary constraints on fields of inquiry. Time would follow the shape of fields unified and configured within a singularity and differentiated as it changed with no necessity for a direction of time that was uniform unless the physical shape of the singularity upon parole was uniform.
Black holes and singularities are consequences rather than appearing from nowhere. Existing mass need contract into a singularity before it may escape. The conundrum of what came first; the chicken or the egg, appears to fit singularities too.
