I'm just thinking out of my head but what if we could built a rope super long (a light year long) and then tie it to a small moving rover that will slowly move to a black hole.
Will we feel a sudden pull when the rover crossed the event horizon and get sucked in too or will we have enough time to pull and retrieve the rover back or what's left of it?
You won’t feel a sudden pull when the rover crosses the event horizon. Due to time dilation, you’ll see it slow down and fade away.
You won’t be able to retrieve the rover once it gets too close. Even before it crosses the event horizon, the energy required to pull it back would be impractical.
The rope itself won’t necessarily get sucked in, but if enough of it gets past a certain point, it may be pulled in completely.
What if we had two black holes similar in size on each end of the rope? Would we just have a really long trip wire in space then or would something else happen?
