Beyond the event horizon in an almost 2D space
The singularity. The center of the black hole
The event horizon is the point of no return around a black hole. This is the boundary beyond which any object that gets there will not be able to escape the gravitational pull of a black hole. As soon as an object crosses the event horizon, it is trapped inside a black hole and cannot leave it. The event horizon is the door, once you enter it, you will never be able to go back out. You will become a part of gravity, or a set of virtual particles, or some unknown kind of preserved information? No one knows.
Even the light is lost there.

The event horizon. The border of the transition.
