Futuristic Megacity Artificial Singularity

Vertical cinematic sci-fi cityscape showing an immense futuristic megacity at night in monochrome [black, white, and cold silver-gray]. High aerial perspective looking down across an endless, dense grid of slender skyscrapers, needle spires, and glowing urban grids stretching toward a hazy horizon. In the right-center foreground, a colossal circular black void or artificial singularity is embedded directly into the city, surrounded by luminous, swirling concentric rings of fine white and silver light trails resembling an accretion disk. Intricately detailed architecture clusters tightly around and beneath the vortex, with metallic reflective surfaces and glowing windows emphasizing colossal scale. Ominous, awe-inspiring atmosphere with volumetric mist, fog, bloom, and high-contrast deep blacks under a dark sky. Ultra-detailed photorealistic digital matte painting style. No people, vehicles, signs, logos, or readable text.
