Within the ergosphere, spacetime is dragged along in the direction of the rotation of the black hole at a speed that varies with distance from the event horizon, becoming zero at the ergosphere.This process is known as the Lense-Thirring effect or frame-dragging. Because of this dragging effect, objects within the ergosphere could not be stationary with respect to the rest of the universe unless they were to travel faster than the speed of light with respect to local spacetime.(Source: Wikipedia).
