The ergosphere outside a black hole is a region where space-time itself is being dragged around due to the spinning of the black hole, making it impossible to stay still. This dragging of space-time can be imagined as similar to taking a long exposure picture on a merry-go-round where your image smears. In this phenomenon, one could witness the back of their own head due to the light being dragged around. Space-time involves events in a 4-dimensional world, where time is considered the fourth dimension. Without events, space-time does not exist, resembling the concept of plotting points in a 4D space-time continuum.
