You are trying to teach your five-year-old brother about black holes at the dinner
table and describe the event horizon like the edge of a plate and the singularity as a
grain of rice in the middle of the plate. How could you improve this analogy to be
more accurate to the nature of the event horizon and/or singularity?
Change your description of the singularity from a grain of rice to a speck of
pepper.
Make sure you mention that the "plate" is square-shaped (with four sides) to
account for all four dimensions in space time.
Remind your brother that this plate/rice analogy only works for stellar-massive
black holes.
Drape a paper towel over the plate to represent the quasar.
