Eon saved the hardest, coolest subject for last: a supermassive black hole. And the first lesson is that a black hole is not just a black dot.
Two parts: the dark center and the glowing disc
Eon draws it in two pieces:
- A big dark circle in the middle — the black hole itself, so heavy that not even light escapes it. That's why the center looks perfectly black.
- A wide, swirling ring around it — what Eon's dad calls the disc. Scientists call it the accretion disc: a band of super-hot gas and dust spinning around the hole and glowing brightly.
That bright ring is the part we can actually see. It's the famous look from the movie Interstellar — a dark eye wrapped in a blazing circle of light.
When the AI goes wild
Because an AI renders the scene, things get gloriously out of hand: planets start orbiting the black hole, gas swirls everywhere, and at one point the Sun itself falls in. It's chaotic and hilarious — but it accidentally shows something true: a black hole's huge gravity really does pull nearby things toward it.
How big?
The biggest ones — supermassive black holes — sit at the centers of galaxies (including our Milky Way) and weigh millions of times more than the Sun.
Try it
Draw a black circle — then don't stop. Add a bright swirling ring around it. The ring is what makes it read as a black hole instead of just a dot.
