An iOS app that simulates a scientifically accurate black hole in augmented reality, ray-traced live with the equations of general relativity.
About Black Hole Sandbox
Black Hole Sandbox lets you explore a scientifically accurate black hole on your iPhone. It traces light through curved spacetime using the equations of general relativity, showing how light bends around the black hole and falls into its shadow in real time.
You can view the black hole in AR to see it warp your living room, or customize it with 37 color palettes, textures, and effects. Replace the accretion disc with emojis, add your own photos to spin around the event horizon, and watch the lensing physics bend everything.
The app lets you orbit the black hole, zoom in, adjust its size and spin, and save custom presets. Black Hole Sandbox is part of a larger universe of projects from Altroad Studio.
