"Generate an image representing Eddington–Finkelstein coordinates, a type of null coordinates used in general relativity to describe black holes, specifically illustrating the four-dimensional spacetime with ingoing and outgoing coordinates, in a style that resembles a mathematical diagram or a spacetime visualization, incorporating elements that signify the removal of coordinate singularity at the event horizon, with connections to Kruskal–Szekeres and Painlevé–Gullstrand coordinates."
