There are three layers of a black hole
Some people think a black hole has an end that you can stick your hand through, while others believe it is just a never-ending whirlpool. However, there is a structure to it. A black hole consists of the singularity, the outer, and the inner event. Each part has a significant role in how the black hole works and affects its environment.
The singularity is the center or core of the black hole. Here everything is compressed to an infinite amount caused by intense gravitational force. The outer ergosphere is the first section where objects can enter; the gravitational pull is not as strong here. If you were an astronaut exploring black holes, you’d want to stay far from the event horizon, the middle layer where nothing escapes. The force is strong enough to push everything to the center.
