Megastructures are large-scale constructions that often push the limits of engineering and architecture. These structures can include space elevators, geostationary satellites, and even entire cities designed to accommodate vast populations. They are typically designed to serve specific purposes, such as energy generation, habitation, or transportation. The concept of megastructures has been popularized in science fiction, but some real-world projects aim to create similar innovations. Examples include the International Space Station and The Great Wall of China. As technology advances, the potential for building even more ambitious megastructures continues to grow, sparking interest in sustainable and efficient designs.
