Into, and out of, a Black Hole?
« on: August 03, 2012, 05:02:21 PM »
Could you theoretically take a very strong cable, one that wouldn't snap from gravitational forces, attach a durable camera to one end, then tie the other end to a spaceship and dropped the camera into a black hole to record what is happening. Then, use the cable to pull the camera back out. Or just send images back along the wire.

Does such a material even exist?

Even if you WERE able to obtain such a material, I have no idea, assuming the camera doesn't get spaghettified when it gets close.

The camera won't get spaghettified, especially if i drop it in a supermassive blackhole where the tidal forces are lower. Assuming a billion mass blackhole and dipping the camera just a bit past event horizon, and camera has 10cm length (longer than needed), there will only be a 11 newton tidal force pulling on the camera.

As for the material, assuming a 0.1kg camera, with a billion mass black hole and dipping the camera a bit past the swarcasdfhchild radius, 500 meganewtons of force would be exerted which equals to about a carbon nanotube cable with a 9cm diameter. With future advances in technology, it should be easily possible to do such a thing.

Also, even if such a material is completely out of our technological capabilities, it shouldn't matter as because the laws of physics don't forbid such a thing, unless, the black hole pulls back on the camera with infinite force.
