Black holes rotate on an axis
As previously mentioned, black holes are celestial bodies that come into existence due to the death of a star. They have similar traits to stars; they both have a gravitational force and an axis. However, if a black hole consumes anything with even slight gravitational pull and rotational motion, it will rotate much faster.
Every object in space that has mass will rotate. For example, black holes rotate on an axis and can disturb any nearby stars or planets when they get close enough.
