‘Inside’ of many black holes… there is a new ‘big bang’, and then another universe, which can form its own black holes, etc.
So… nope, not turtles all the way down, instead, singularities.
So then we are all inside a … progenitor universe’s black hole, and it is seemingly fundamentally impossible for anything above a subatomic scale to survive the transition… and thus it is also fundamentally impossible to know how long this has been going on or how this all started.
