If enough matter gets concentrated into an area that is small enough, gravity can become so strong in the immediate surroundings that nothing can escape from that area. That is called a "black hole". For more information, read the Wikipedia article with the title "black hole".
That's basically the description of a black hole.

The black hole itself cannot be seen, however, its pulling effects of the surrounding area can be seen.
The event horizon of a black hole is a spherical area round the center of the black hole; it has a radius proportional to the mass of the black hole - a radius of about 2.95 kilometers for every solar mass.
A black hole is an area where gravity is so strong that not even light can escape from it. This happens when a massive star collapses in on itself, creating a region of spacetime with an intense gravitational pull.
A small area of immense mass in space from which nothing can escape is called a black hole. Black holes are the most mysterious and the strangest objects in the sky.
The ergosphere is an oblate spheroid region outside of the event horizon, where objects cannot remain stationary. While objects and radiation can escape normally from the ergosphere, there is still gravitational frame dragging of matter which is orbiting a black hole. Note: Think of the black hole's ergosphere area being like the Earth's graviational influence area of Low Earth Orbit.
There is no definite boundary for matter not being pulled toward a black hole. At large distances the effects of a black hole's gravity are not different from that of a different object of the same mass. How far out a black hole's gravity is dominant depends on that black hole's mass and its proximity to other massive objects.
A Schwarzschild black hole is a non-rotating black hole. The Kerr black hole is a rotating black hole. Since the latter is more complicated to describe, it was developed much later.A Schwarzschild black hole is a non-rotating black hole. The Kerr black hole is a rotating black hole.
