Una vasta città futuristica fluttua nell'oscurità dello spazio

Create an ultra-detailed, hyper-realistic science-fiction megastructure in a vertical 9:16 composition, depicting an immense futuristic white city floating in the depths of space, stretching across thousands of kilometers in every direction. The city features colossal, organically curved architecture, monumental towers, sweeping megastructures, interconnected platforms, vast terraces, and impossibly large buildings with smooth, sculptural surfaces and intricate geometric details. Entire urban landscapes flow seamlessly into one another, creating the impression of a boundless technological civilization built on an almost incomprehensible scale. A gigantic, continuous white wall rises thousands of kilometers above the city, its immense curved surface disappearing into the darkness of space, dwarfing everything beneath it. Tiny lights, distant structures, and miniature spacecraft provide subtle scale references, emphasizing the extraordinary size of the architecture. Brilliant ivory-white materials, polished ceramic surfaces, and pale metallic accents reflect soft celestial illumination, contrasting against the deep blackness of space, distant stars, and faintly glowing nebulae. Dramatic cinematic lighting creates delicate highlights, deep architectural shadows, atmospheric depth, and a powerful sense of scale. An expansive wide-angle perspective reveals layers of futuristic infrastructure extending toward the distant horizon, with monumental structures fading into cosmic haze. The overall aesthetic is pristine, alien, monumental, and awe-inspiring, presenting a mysterious utopian civilization that feels both technologically advanced and almost impossible to comprehend. Extreme architectural detail, physically realistic materials, sophisticated global illumination, immense environmental scale, sharp structural definition, cinematic science-fiction realism, and breathtaking visual depth. --ar 9:16 --hd --v 8.2
