One of these things intersecting with Earth would be an interesting way for humanity to end.

The real question is, with the warping of space-time, how long would it take for us to perceive the end? Would it seem like the black hole started moving incredibly slowly, or would our planet start getting torn apart before then?

This is the premise of a book by Thomas Wren:

From (distant) memory it was a fun read with some science but not overly realistic wrt to how humanity would react.
