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. —A Black Hole Is NOT a Hole, Carolyn Cinami DeCristofano What information in the passage helps answer the question asked previously? Gravity smooths out even the lumpiest black hole. A symmetrical collapse forms a smooth hole. Erratic gravity pulls a black hole in different directions. A collapse can be symmetrical or lopsided.
