Could the source of dark energy be our parent black hole feeding?

[Bob Walance]

TL;DR Summary

If the creation of our spacetime is linked to a parent black hole, it seems that it might be possible that the source of our dark energy might simply be due to our parent black hole being in a feeding cycle.

About a year ago, I heard Leonard Susskind discussing how entangled black holes could create spacetime. As I was listening to Prof. Susskind describe the mechanisms for creating entangled black holes, and how these black holes might create their own spacetime, it occurred to me that if we were part of black-hole-created spacetime, and if our parent black holes were feeding, the mass/energy that they were devouring might inflate our spacetime - just as we detect that dark energy is (or was) doing.

Since then, I am aware of others that suggest that we might live inside of a black hole. There's even a PBS Space Time episode "Could the Universe Be Inside a Black Hole?"

Is this a plausible possibility that our dark energy is due to a feeding cycle of our parent black hole?

Aren't the observational data favoring infinite universe? Hence we can not be inside a black hole.

Personal speculation.

That’s not real physics, it’s entertainment. Watching this stuff is fun, but it doesn’t work as a way of learning any physics.

No, almost certainly not. For starters, how do you create spacetime, how do you 'inflate' it with the positive energy of regular matter, and how would this feeding mechanism be linked to dark energy, given that dark energy is thought to scale with the size of the universe*, not the number of black holes?

*More like distance between objects and the density of the universe.

Where? Please give a reference.

if we were part of black-hole-created spacetime

We aren't. "Black hole created spacetime" (which is a very poorly chosen phrase, if Susskind is referring to what I think he's referring to) is inside a black hole. We're not inside a black hole.

Thread will stay closed by the request of the OP. He realizes that it is a bit too speculative for PF, since he is not able to find the original reference. Thanks @Bob Walance
