Smallest objects in universe? Cause gamma ray burts out of two sides. [[Black holes are toruses]]? [[Event horizon]] makes it so we can't know anything about what goes on inside. [[Kurzgesagt]] has a plushie that contains a black hole on one side and a [[White hole]] on the other, which made me think about the relationship between the two. I suspect [[White holes are the output of black holes]] ([[Opinions should be strong, but weakly held]]).
