🕳️ Black Hole Simulation Interface: Mass, Accretion Rate, Spin, Jets, Lensing and Matter Infall in Six Scenes

A ray-traced black hole with sliders for mass (1-100 solar masses or 10^6-10^8), accretion rate and spin, four visualisation modes (realistic, Flamm spacetime grid, light rays, X-ray) and six scenes from a stellar hole to tidal disruption of a lava planet. Live readouts of horizon, photon sphere, ISCO, efficiency, disk temperature and luminosity come from Kerr formulas and are checked against independent numerical integrations; the shader is a pseudo-Newtonian approximation with ZAMO frame dragging.
