GRAVITATIONAL LENSING
Light bending.
Light takes the long way.
The study
Neeuman has simulated black-hole shadows and gravitational lensing from multiple observer perspectives. This numerical experiment follows modeled curved-spacetime light paths; the recorded example uses a procedural distant starfield rather than astronomical observations.
A numerical gravitational-lensing experiment, not an astronomical measurement or universal accuracy benchmark. An angular renderer seam may be visible.
