Read this excerpt from A Black Hole is NOT a Hole. If the star was spinning before the collapse, then the black hole will spin, too. If the collapse is perfectly symmetric, a smooth black hole forms. On the other hand, even a slightly lopsided collapse leads to a lumpy black hole, with erratic gravitational effects. The gravity might be strong in some places and weak in others, and pull in different directions. However, a lumpy hole won’t stay lumpy for long, because its own gravity will work to smooth it out.

Which would be the best title for a chart that organizes the information from the excerpt?
