Black Hole — live physics simulation
Every frame, light rays are bent by the curvature of spacetime around a
non-rotating (Schwarzschild) black hole and traced back to what they hit.
This is computed live from general relativity in your browser — it is
not a photograph and not telescope data.

What's physically real here: gravitational lensing (the ring of
distorted background stars), the photon ring / black shadow at ~2.6×
the event-horizon radius, the Einstein ring, and
relativistic Doppler beaming — the disk side rotating toward you looks
brighter and bluer (the same asymmetry in the 2019 Event Horizon Telescope image and in
Interstellar's Gargantua). What's simplified: photon paths use a
standard post-Newtonian light-bending approximation (not a full geodesic integrator), the
hole is non-spinning, and the accretion disk and starfield are procedural, not measured.
