Remember the space elevator in The Wandering Earth 2, and whether its concept can be realized? The 36,000-kilometer space elevator shown in the film is amazing, but its realizability has sparked widespread discussion.
First of all, we need to clarify the basic principle of the space elevator. The concept of a space elevator is based on the idea of transporting goods and people through a cable that connects the ground to space. This cable will be fixed to the ground while extending to a height above the geosynchronous orbit, forming a stable orbit. Through this cable, the manned and cargo-carrying capsule can be ascended or lowered along the cable, enabling low-cost, high-efficiency space transportation.
However, the realization of a space elevator presents a huge technical challenge. First of all, the material requirements for the cables are extremely high. It needs to be lightweight, high strength and highly resistant to wear to withstand enormous tensions. At present, carbon nanotubes are considered to be the ideal material for the manufacture of space elevator cables, but the existing carbon nanotube technology cannot meet such high requirements.
Secondly, the stability of the space elevator is also an important issue. Due to the rotation of the Earth and the movement of the space elevator, the cable will be exposed to the effects of enormous centrifugal and wind forces. How to ensure the stability of the cable and avoid breaking or losing control is a technical problem that needs to be solved urgently.
In addition, the safety of space elevators cannot be ignored. In the movie, the space elevator is portrayed as a convenient means of transportation, but in reality, it can be a target for terrorists and criminals. Once a space elevator is attacked, the consequences will be unimaginable. Therefore, how to ensure the safety of the space elevator is a problem that needs to be studied and explored in depth.
Despite the challenges associated with the implementation of the space elevator, its prospects are still favored by some scientists and engineers. They believe that with the advancement of science and technology and the development of material science, the manufacture of space elevators will become possible. Moreover, the realization of the space elevator will greatly promote the exploration and utilization of space by mankind and open a new era for mankind.
In conclusion, the space elevator concept in The Wandering Earth 2 is exciting, but its realization still faces huge technical challenges and safety issues. We need to delve into and explore these questions and find solutions to make this great dream a reality.
