Why do things that enter a black hole disappear?
Gravity
The gravitational attraction of a black hole is extraordinarily large, it is so strong that light itself cannot escape. Once any particle passes the event horizon it will not escape the black hole.
The reason we see things is because light reflects off an object and travels to your eyes, if light cannot travel away from the black hole because of gravity then that light can never reach your eyes and so all you see is black (no light)!
So you will see an object approach a black hole but once it passes the event horizon you will no longer see the object.

When an object passes through a black hole's event horizon, it approaches the singularity at the center of the black hole, where it is compressed and stretched to an infinite density point known as a singularity, where the laws of physics as we know them break down. This process is called spaghettification, and it means that anything that enters a black hole, including light, is effectively lost from our observable universe. This phenomenon is caused by the extreme curvature of space-time near the black hole.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
