Enable JavaScript to explore the ASCII black hole.
This black hole is an artistic experiment. Every point of light is a character, selected for its brightness and drawn onto a moving grid.
Drag an asteroid, star, or probe out of the tray, then release to throw it. Its speed and direction affect its path. Near the core, differential gravity pulls the fragments into strands. Each captured object adds mass and enlarges the illustrated horizon. Click a tray object to launch it without dragging.
At the display's critical-mass threshold, the accretion disk erupts in a bright outburst and throws gas outward. The black hole stays intact; a broad gas ring remains in orbit. Supernovae are explosions of stars, not black holes. This threshold and the mass readout are visual shorthand, not real astrophysical limits.
