What would happen if I stuck a really long pole into a black hole?

Would the part that is in the event horizon break off if I pulled back on the pole?  Would it get sucked in instantaneously or would it take time?

So here's you, chillin', hanging out *by some witchcraft* at rest relative to the black hole.

And not just any black hole, right? A *magic* black hole. A black hole that is not boiling and seething with a highly energetic stretched horizon.

You begin lowering your pole. Unseen by you, the stress on the pole begins to climb. Soon, there's insane internal stress on the pole, due to the difference between four-acceleration where you are and where the end of the pole is.

Then snap. Pole breaks. And it will always break *where it can be observed by you.* That is, it will break *before* the four-acceleration on the end of the pole goes infinite at the event horizon. The fragment or fragments that break off fall toward the black hole and vanish; the bit you're holding on to remains intact until you either pull it back, or lower it farther until it, too, breaks.

Don't ask what would happen if the pole were infinitely strong. Everyone always does, and the answer's always the same: you can't have infinitely strong materials and black holes in the same universe.
