I like some of these sentiments and would like to respond with some more ideas. but first, refer to my comment about "defeating my argument". Maybe A black hole in another universe would, instead of producing a black hole that is our universe, would more likely produce a White Hole. And that's maybe where we are; in a white hole and as you say we produce our own Black holes and so on. The hierarchical problem.
Your thought on compressing space: is this not what happens when a black hole feeds mass? What might happen to us if our white hole (if that's what we are) were to stop being supplied with space and matter from the 'upper' black hole? In that situation, the expansion would stop, possibly, and as a result of Black Holes continuing to feed, we would have the situation you alluded to: shrinkage.
We probably would not notice as time is always positive (except when it isn't). Maybe I can suggest some ideas that, to me at least, show exactly what time is and some consequences - because you raised it as an issue.
Should we discuss this here or as a Separate Heading? It would be a whole lot easier if I could post JIF pictures as illustrations but I know not how!
