#VALUE!
In the past, cities were constructed with private and public buildings erected independently, without planned connections between them. This is how cities were typically formed for thousands of years, until the modern era when many governments concluded that the chaos in urban development could no longer be permitted. Every new city has to be comprehensively planned, accounting for its streets, homes, and public buildings.
Today, advanced countries are investing heavily in planning new cities. The results are truly stunning. Now, let's imagine the 'City of the Future,' built with cutting-edge technological knowledge: the city's diameter is about ten kilometers. It is encircled by a massive electronic wall featuring millions of(!) openings controlled by sensors.
These sensors manage the openings to either accept or reject various raw materials entering the city, based on data received from the control center. If a specific material is needed in a particular quantity, the sensors will keep the relevant openings open just until the exact desired quantity enters and will then close the gates to any others.
Any material reaching one of the millions of openings not required by the control center will not enter under any circumstances! All incoming materials travel along a precise path that leads them to the production halls where they are needed. Those same sensors also open the countless gates for waste materials being carried out on conveyor belts, allowing them to exit.
At the very heart of the city stands a special, massive circular hall, approximately a kilometer in diameter. This hall is heavily guarded because it houses and stores all the technological secrets that operate the city's advanced industrial plants.
Information is stored in orderly rows of coils containing billions(!) of symbols and codes. This data is meticulously read by countless robots that dutifully follow instructions. The city itself contains numerous halls equipped with advanced machinery that manufactures valuable items from various materials.
Assembly centers receive these manufactured items from different halls and piece them together. These halls and centers are connected by countless streets, pathways, and corridors, meticulously designed, ensuring that any needed material or item is transported immediately through these interconnected routes on conveyor belts without any human intervention.
Everything operates automatically based on symbols and codes read by the robots in the aforementioned control center. Instructions are delivered directly to all halls, centers, and conveyor systems in the corridors through a sophisticated internal communication network. From a bird's-eye view, a meticulously organized system of halls and buildings would be visible, arranged with astonishing precision and beauty.
In the city's streets, an incredibly coordinated flow of endless transport and logistics systems can be seen, connected to countless corridors, halls, and assembly centers, conducting endless materials and items to and from them. These complex systems all operate simultaneously, coordinated astonishingly by the control center in the giant hall at the city's core.
And as if we haven't already marveled at this city's incredible technological prowess, here's the most astonishing piece of news (hold onto your seat, dear reader...): the city, with all its halls, facilities, walls, and advanced systems, is connected to a smart system in the control center, complete with special software capable of—using the most advanced technology—duplicating everything automatically when needed, creating an entirely new city with all its wonders! If humanity reaches such a technological milestone, it would undoubtedly mark not just a historical milestone but the realization of a modern scientific marvel, akin to bringing science fiction to life.
But, truly? Is it known that such a model has existed since the first forms of life were created by the Creator of the Universe? This 'City of the Future' exists within every cell of every living being. To discover this marvelous city, all we have to do is take a single cell from a living organism, which measures less than one-hundredth of a millimeter(!), and observe it under tremendous magnification. If we magnify it a billionfold, we will unveil the astonishing city described above, with a ten-kilometer diameter.
(For illustration: "Magnifying a cell a billion times" implies lining up a million cells side by side, and once a million cells are accumulated, placing alongside them another nine hundred and ninety-nine(!) such groups of a million cells. The result will be the size of a single cell magnified a billionfold. Only such an illustration assists us in fully grasping with our minds the magnitude of the details mentioned above.
