It's a hole in spacetime in the sense that the inside of the Black Hole is completely cutoff from the outside, with the exception of Hawking radiation. A black hole's interior is causally separate from the rest of the universe.

This doesn't solve the problem. Spacetime itself is a hole, so you're saying a black hole is a hole within a hole, and we can designate an infinite number of holes within a hole.

Sounds like something you'll read about in modern physics.

Isn't the idea that the universe (or the superset of universes) a hole within a hole (or an infinite number of holes within a hole) something physicists already entertain?

E.g. there are several theories about how our universe itself is the inside of a black hole, and so on.

The author does take a wild ride into the world where, via Hawking radiation, the interior is NOT causally separate, yet quantum-ly entangled.
