- TL;DR Summary
- Black holes have been depicted as two-dimensional and 3-dimensional, so which is it?

When looking at depictions of black holes, we often get illustrations of a two-dimensional space-time where everything spirals into a "hole". The hole then leads to a singularity usually depicted as a funnel shape. Then there are images of black holes shown as spherical with glowing rings swirling around them like in the movie "Interstellar". If black holes are spherical, does it mean that the singularity is the center of that "sphere"? Then what defines the event horizon if the black hole is a sphere?
