[1/5/2/2/1/1] Gravitational lens effect


The image distortion of a background spiral galaxy by the complex gravity of the two black holes in the contracting de-Sitter universe is visualized. Initially we can see no galaxy in front of the camera because the galaxy exists out of the area where light rays can reach to the camera (inversely speaking, no light ray emitted from the camera toward the past time direction can reach to the galaxy). Then the galaxy appears and further the two event horizons of two black holes appear. The event horizons spread gradually in front of the camera because the distance of the camera and the black holes decreases in the contracting space-time. Fortunately the camera does not fall into the event horizons because the camera is standing in the exact middle position of the two black hole and there is no gravity at the camera position.
