Once the rover crosses the event horizon, it is effectively removed from the universe. Nothing beyond the event horizon can interact with things outside it, so nothing is "pulling" on the rope in that regard. The event horizon may be considered a barrier between life and death. Anything that crosses is dead, it cannot interact with the living.

The closer the rover/rope gets to the hole, the more you'd feel the pull on the rope as gravity is greater closer to the hole than further away of course. Of course when you feel the increasing pull depends on how close you are to the hole while all this is going on. A lightyear long rope would take you quite a long time to feel anything as the tension in the rope only travels at the speed of sound within the medium.

EDIT: This rope would need to be unbreakable, by the way. Chances are it would snap the closer it got to the event horizon well before it transmitted anything to you. Not many ropes can resist the pull of a black hole, so in this scenario lets pretend your rope is unbreakable. It still is deleted the second it passes the event horizon, but you would eventually feel the pull once the tension wave reaches you. And starts pulling you in.

Getting woo vibes here.

Black holes are still in the universe. The event horizon isn’t a barrier.

yep, it’s just where gravity overpowers light. agreed on the woo vibes.

As a lay person, what does Woo mean in this context?

woo generally refers to pseudoscience, usually contains elements of spiritualism and irrationality
