Light passing by the Kerr black hole

Описание к видео Light passing by the Kerr black hole

The white circle represents the outer event horizon, the gray circle represents the inner event horizon, and the dotted circle represents the ergosphere. The angular momentum of the black hole is perpendicular to the shown plane, and the black hole is rotating counter-clockwise.

Particle trajectories are calculated using Hamiltonian mechanics. The Hamiltonian of a particle is the time component of its 4-momentum, derived from the length of 4-momentum (mass of the particle) in a given space-time metric as a function of canonical coordinates and momenta.
