社交媒体帖子 - Monochrome Megacity Black Hole

Create a vertical cinematic sci-fi cityscape viewed from a very high aerial angle at night, in monochrome black, charcoal, silver, and cold white. The scene shows an impossibly vast futuristic megacity packed with thousands of tall skyscrapers, sharp spires, dense glowing windows, and intricate illuminated street grids stretching to a hazy horizon. In the center-right foreground, place a colossal circular black void like a perfectly dark sinkhole or artificial black hole embedded in the city, surrounded by countless bright concentric rings of white light trails that swirl around it like long-exposure traffic or orbital data streams. The light trails should form a wide vortex disk, brightest on the left side and fading into a deep black center. Buildings continue around and partly into the vortex, with some towers silhouetted against the glowing rings. The atmosphere is misty, high-contrast, and apocalyptic, with volumetric haze, bloom, fine detail, subtle film grain, and a luminous horizontal fog band near the distant horizon. No people, no vehicles visible as objects, no text, no logos; emphasize overwhelming scale, cyberpunk architecture, and the surreal gravitational distortion of a city being swallowed by a black hole.
