As humanity faces unprecedented challenges such as population growth, resource scarcity, and environmental pollution, we must explore new living spaces for survival and development. The future stage will not be limited to Earth but will expand across the entire solar system. In this vision, humanity will transform the solar system to establish a brand new world—Solar City. This grand plan involves not only technological innovation but also a test of human wisdom and courage.
The first proposal is the Dyson Sphere, where future humans would live within a hollow sphere with a radius of 150 million kilometers, encompassing the sun. This solution addresses energy issues while providing ample living space. The second proposal is the Ring World, resembling a massive rotating wheel with the sun at its center, allowing inhabitants on the ring to experience various seasonal changes. The third concept is the Alderson Disk, which looks like a giant record with gravity perpendicular to its surface, also aimed at providing a suitable living environment.
Although these ideas are filled with science fiction elements, they showcase humanity's limitless imagination and exploratory spirit for the future world.
