[1/5/1/1/6] Apparent view of swing by
The movie when the camera is swinging by the black hole.
The camera freely approaches to the black hole, moves around the black hole five times, and then leaves from the black hole turning its direction inversely from the initial direction. In a wide sense this is a kind of swing by motion using the black hole. In Newtonian physics this type of motion (Keplerian motion) is impossible because a free fall trajectory is one of an ellipse, parabola, or hyperbola while in general relativity it is possible as explained by the word perihelion shift. The initial position of the camera is far from the black hole 10 times of the gravitational radius and the initial velocity is 0.8 times of the light speed.
