What Shape Are Black Holes? Yes.

The video explores the complex shapes of black holes, starting with the familiar funnel depiction and moving to the event horizon's topological sphere. It discusses Stephen Hawking's theories and the possibility of black holes being ellipsoidal due to their spin. The video then delves into higher dimensions, suggesting that black holes could appear as doughnuts or lens spaces in 4D or more. These concepts remain hypothetical, requiring exotic matter and additional dimensions beyond our current understanding.
