I have now! Thanks for the recommendation. That's pretty crazy to think about.

Funny thing, I've been saying for decades that "space expansion" would be effectively undistinguishable from "particle contraction", so falling into a black hole and getting crushed/compressed by it, would look like... the universe we see, with the singularity being somewhere around the Planck's length, several orders of magnitude down from where we are (assuming Plank's length would remain constant).
