WHAT HAPPENS WHEN ANY OBJECT GOES IN BLACK HOLE?
Suppose that, possessing a proper spacecraft and a self-destructive urge, I decide to go black-hole jumping and head for an uncharged, nonrotating (“Schwarzschild”) black hole. In this and other kinds of hole, I won’t, before I fall in, be able to see anything within the event horizon. But there’s nothing locally special about the event horizon; when I get there it won’t seem like a particularly unusual place, except that I will see strange optical distortions of the sky around me from all the bending of light that goes on. But as soon as I fall through, I’m doomed. No bungee will help me, since bungees can’t keep Sunday from turning into Monday. I have to hit the singularity eventually, and before I get there there will be enormous tidal forces– forces due to the curvature of spacetime– which will squash me and my spaceship in some directions and stretch them in another until I look like a piece of spaghetti. At the singularity all of present physics is mute as to what will happen,
No one knows for sure what happens when something falls into a black hole, since of course the information can’t be relayed back by an observer and the known laws of physics break down. However, it is thought to go something like this: The object is attracted to the black hole by its gravitational field. As it starts to approach the event horizon (the “point of no return” beyond which gravity is too strong for anything to escape), it will get caught up in an extremely hot, rotating disk of matter falling into the black hole called the accretion disk. Eventually, it will actually cross the event horizon, although there is no perceptible change from the object’s point of view. The outside world can still be seen (although it may be distorted due to the gravitational bending of light) from inside, but there is no longer any way of sending information back to the outside world. As the object continuous to accelerate towards the center of the black hole, it will be ripped to shreds by tidal
