VIDEO:
This video illustrates the difference between a spinning and non-spinning black hole. It shows a side by side comparison between a spinning black hole and a non-spinning black hole. In each, lines of space-time are drawn around the event horizon. In the video, the event horizon is surrounded by a blue glow, which represents gas just before if falls past the event horizon. The innermost stable orbit is the ring of gas outside this blue glow. Space-time is curved around the black hole which is rotating. As a consequence, around a rotating black hole the gas can be in a closer orbit.
