# Black Hole

> Gravitational lensing simulation — a black hole warps spacetime around it, bending starlight into Einstein rings. 500 background stars deflect, amplify, and stretch near the singularity. A spinning accretion disk of 300 hot plasma particles orbits with Doppler brightness shift — the approaching side glows brighter. Photon sphere ring, event horizon, and subtle space distortion rings. Move your mouse to drag the black hole through the star field. Smoothed position tracking. Configurable mass, lensing power, disk speed, star count, and colors. Supports content overlay as children. Zero dependencies.
