Humans start the space migration program? These space city designs are all sci-fi, which one do you think is possible?

The launch of Shenzhou XIV ended perfectly, congratulating China on taking another step forward from the completion of the construction of the space station. Now science and technology are more and more developed, and the exploration and imagination of space is more and more bold and sci-fi. The design concept of "Space City" seems to be closer to reality. What are the design ideas of the "space city" with wide brain holes? Let's see. ...

As early as 1926, tsiolkovsky, the originator of human space technology, had the idea of building a space city in outer space. One day in the future, the earth will no longer be suitable for human survival, and residential areas will be established in the vast space. Artificial gravity is generated by rotation to realize gravity environment, and indoor temperature and humidity are suitable for plant growth through manual control. So what kind of space city design ideas will be there to realize the human migration plan?

From 65438 to 0975, O 'Neill began to draw his space city design concept at Stanford University and made it into a three-dimensional image. Among them are engineers, space scientists, physicists, artists, urban planners and architects, and experts from all walks of life. With the cooperation and participation of many experts, O 'Neill completed the design concept of Space City. He conceived "renderings" of three space city schemes. Let's take a look at his design ideas.

The first one: Stanford Circle. It is the strongest concept of space colonization put forward by scientists such as O 'Neill. 1 mile long ring can live close to 1 10,000 people, can be made into rings with different radii, and the largest ring can even provide living space of10.4 million people. By installing a mirror on the top of the inner ring of the circular ring, the sunlight is reflected to the outer residential area, providing people with daytime changes close to the alternation of black and white on the earth. But because of the high cost and many unresolved technical problems, it looks cool, but it only stays on the Hollywood screen. Is there a more reliable design scheme?

The second one: O 'Neill cylinder. The design consists of two giant cylinders rotating in opposite directions, which avoids the gyro effect and makes the structure more stable. The cylinder is 5 miles in diameter and 20 miles in length. The rotation of two cylinders produces artificial gravity, which can provide living and living for 6.5438+0 million people. The cylinder uses a metal mirror to control the entrance of sunlight, and the energy source is solar energy. Building materials are basically water from comets, plant seeds from the earth and building materials from nearby asteroids. As soon as you listen to this plan, you don't think we can realize it now. Maybe it will be hundreds of years before mankind can conquer the whole solar system and make use of all the materials in the solar system. The second one is not very reliable and far away. Is there a more reliable and closer design scheme?

Third, the bernal Ball Scheme was first put forward by British scientist bernal. O 'Neill and scientists replaced the Stanford circle with this scheme. In fact, the concept is similar to that of a ring, except that its space is composed of spherical spaces connected in series into a ring. The diameter of the bernal sphere can vary from 2 miles to 10 mile as required, which can accommodate 75,000 people. The sphere generates gravity by rotating, and huge windows are designed on both sides of its "equator" area, and sunlight is reflected by mirrors placed outside the sphere. The sense of gravity in the equatorial region is also closest to the experience on earth. The "two poles" of the sphere are affected by gravity, so they can't stay for a long time, which makes people dizzy. Soon after the plan was put forward, people were equally optimistic about it. Supporters believe that this space city will become a reality in the 1990s at the latest, and then NASA can build a Bernard sphere every two years.

But the reality is that there is not even a mature theory yet. It is said that there is a more ambitious space station plan in our country, which is expected to be thousands of times larger than the current scale and can support thousands of people to live and live. The research layout of the future lunar scientific research station is also being implemented steadily. Compared with the "space city", these are closer to us, and we may witness this great achievement with our own eyes in our lifetime.

Therefore, the design concept of "Space City" still has a long way to go. With the continuous breakthrough of scientists, it will eventually become a reality.
