Black Hole - Horizon

Fly around a spinning black hole rendered in real time on your device's GPU. Every pixel traces a ray of light through curved Kerr spacetime, so what you see is what general relativity actually predicts: the dark shadow, the far side of the accretion disk lensed up over the top, the thin photon ring, Doppler beaming that brightens the approaching side of the disk, and gravitational redshift near the horizon. • Adjust the black hole's spin, the disk temperature and the camera distance • Drag to orbit, pinch to zoom, two-finger drag to look around • Cinematic tour mode, plus a dive toward the event horizon • Live readouts: horizon radius, innermost stable orbit, time dilation • Disk colours from physically based blackbody spectra • Relativistic jets and bloom, with quality presets for every device No accounts, no ads, no tracking.
