Black holes have three layers, the outer event horizon, inner event horizon, and the singularity. The event horizon of a black hole is the boundary around the mouth of the black hole, past which light cannot escape. Once a particle crosses the event horizon, it cannot leave. Gravity is constant across the event horizon. The inner region of a black hole, where the object's mass lies, is known as its singularity, the single point in space-time where the mass of the black hole is concentrated.
The
outer event horizon of a black hole acts like a point of no return. So you will
fall into a black hole but will have no means to come out of it as soon as you
reach the outer event horizon of a black hole, as if you have entered into a
strong whirlpool, within water and so you cannot come out but to fall within it.
So you fall into a black hole against your wish to come out of it as soon as you
reach outer event horizon of a black hole.
