Light rays scattered between two black holes with adjustable mass ratio, revealing chaotic capture boundaries, shown in equivalent classical optical system.
Displays a spray of null geodesics navigating the gravitational field of two extremally charged black holes in a Majumdar-Papapetrou spacetime. Each ray is integrated and drawn as a tube whose color encodes which black hole (if any) captured it. A mass-ratio slider redistributes the total mass between the two holes, revealing how the chaotic scattering pattern changes.
Controls: Click and drag to orbit, scroll to zoom.
