Black Hole Simulator

Click anywhere on the canvas and watch matter spiral inward, stretched and bent by a simulated gravitational singularity. Black Hole Simulator lets you place a black hole, then toss particles into its influence and observe how they orbit, slingshot, or get swallowed depending on their angle and velocity. The accretion disk builds up around the event horizon as captured material accumulates, giving you a visual sense of the physics without requiring a textbook.

It's a genuinely meditative thing to watch — a few particles become dozens, orbits stack on top of each other, and the whole system starts to feel alive. The simulation runs in real time, so small changes to where you click produce noticeably different trajectories. If you enjoy this kind of emergent, physics-driven play, interactive simulations on Launch Arcade have plenty more to explore.

Fluid Simulation goes in a different direction — fluid dynamics rather than gravity — but scratches a similar curiosity about how forces shape motion. Black Hole Simulator runs best on a larger screen because the full orbital paths need room to read clearly at a glance.
