I enjoyed this Veritasium video on the subject, which includes Penrose Diagrams.

Sorry man, that's not what this is about.

It's not? Schwarzschild has a space-like singularity. That's the wiggly horizontal line at the top left of the diagram. If you are in the black hole you can't avoid hitting it. Seems to be exactly what the paper is remarking on.

Yes it is?
