An assumed ball composed of a set of massive test particles without interactions is disrupted by the strong tidal force of a Kerr black hole. The black hole spin is a = 0.8. The radius of the ball is 4 r_g. The initial coordinates are r = 20 r_g, θ = 90°, φ = 0°. The coordinate times are t = 0, 22.5, 45, 67.5, 90 for images from right to left. A circle at the left represents the event horizon.
