The edge of a black hole, the event horizon, is a boundary that marks the point of no return. Once an object crosses the event horizon, it cannot escape and will be ripped to pieces, atom by atom.

Once gas comes within a distance about a million times larger than the event horizon of the black hole, it becomes gravitationally captured. At this point the gas becomes fuel for the black hole engine.
