Artificial magnetic field of Martian immigrants

Do you often look up at the stars? I fantasize that I can reach a planet in a secluded galaxy, where there may be mountains and flowers everywhere and deserts everywhere.

Anyway, we are interested in moving to another planet. However, judging from the severity of the alien environment, with our current scientific and technological development, it is an unreachable dream to settle there.

So many people suggest that we can try to transform those planets, or build a "large ecological cabin" on the earth and transport it by rocket. This statement sounds easy, after all, it is to copy the earth's environment in the "incubator".

In fact, scientists put this idea of artificial large-scale ecological cabin into practice a long time ago. They put four men and four women in a closed space to test whether human beings can live normally in it. But it turns out that human beings may be trapped on the earth forever and never realize their dream of emigrating to another planet.

This experiment, called Biosphere 2, is a miniature artificial ecological circulation system, covering an area of about10.3 million square meters, and it is a large "glass room".

It is said that it was invested by Edward P. Bass, a rich American. Maybe he wants to have some fun for the plain life. He said that he would copy a "small earth" to prepare for future space immigrants.

This experimental base is located in the northern desert of Tucson, Arizona, USA, and the surrounding environment is very desolate. Because it is located in the desert, there is plenty of light here, and the site selection person said that it is very similar to the environment in space.

The ecosphere was built in May of 199 1 year, with an internal filling volume of 204,000 cubic meters, consisting of 6,000 pieces of glass and 80,000 white-painted steel beams, with a total cost of more than 65.438+0.5 billion US dollars.

After the completion, scientists put four men and four women into it and announced that Biosphere 2 was officially put into operation. It is worth mentioning that people who enter this life are not ordinary people, but scientists who participated in the design of Biosphere 2. 1991At 8: 00 am on September 26th, 15am, these eight scientists entered Biosphere 2 and began a two-year "isolated" life.

In order to obtain real experimental results, the scientists who built Biosphere 2 put a lot of energy into it. From the overall construction, this glass house is not only isolated from the outside world at the top and around, but also welded with 500 tons of stainless steel plates on the ground to ensure complete isolation from the outside world.

Not only that, there are various environments in Biosphere 2, such as rainforests, swamps, beaches, grasslands, and even a man-made ocean 25 feet deep, although it looks more like a large swimming pool. But it is not easy to do so many things. In order to ensure the normal operation of the ecological cycle, scientists have also placed more than 3,800 kinds of animals and plants in it, such as chickens, ducks, fish, sheep and other creatures, which have been kept in captivity.

I believe that after reading the above introduction, you will feel that this place is simply the legendary "Xanadu". It should be a very happy thing to be chosen to do the experiment, but the reality has given mankind a slap in the face and wants to play the role of "God" to copy the earth's environment? Humans are so naive.

At the end of September, eight scientists entered Biosphere 2 together. At that time, they were confident that there was no pressure to double in such a perfect ecosystem, let alone live for two years. After a few months, they found that the situation was not as good as they thought.

According to the monitoring of scientific instruments, the ecological environment of Biosphere 2 has begun to deteriorate. The main performance is that the carbon in the soil changes into carbon dioxide after contacting with oxygen, which leads to a significant decrease in the oxygen content in the air, from the normal 2 1% to 14%.

As we all know, oxygen and water are necessary conditions for living things. However, in such an environment with extremely low oxygen content, the experimenters quickly developed hypoxia reaction, and they felt dizzy. In addition, plants and animals are also affected by hypoxia. Of the 25 vertebrates put into it, only 6 survived. As for plants, after insects die, more than half of them die because of lack of pollination.

At this time, the whole Biosphere 2 seems to be caught in a vicious circle, with creatures dying and oxygen concentration decreasing. By February of 1993, researchers had to manually inject oxygen into it, and the experimental declaration of "completely closed for 2 years" was completely reduced to a laughing stock.

More importantly, there is friction between the eight scientists who live in it. Obviously, there is a huge contradiction between strangers from five different countries, so the whole experimental process of Biosphere 2 is not very harmonious. Many media said that the failure of Biosphere 2 experiment was due to the failure of scientists to ensure the oxygen circulation was infallible, and on the other hand, it was caused by the struggle between eight people and the crisis of trust.

It is worth mentioning that although the experiment of Biosphere 2 failed, it is still running. According to relevant data, from July, 20 1 1, the University of Arizona took over this project and carried out various studies in it. It is said that they are also open to tourists from time to time, so that everyone can visit this "failed but significant experiment".

Judging from the investment and scientific and technological means used by Biosphere 2, this experiment can be regarded as a "serious" implementation. According to its introduction, at that time, the design team referred to various data of the earth's biosphere and built it after scientific experiments, but this foolproof experiment failed in theory. What does this prove?

Obviously, this proves that the earth's biosphere is unrepeatable. We think that science and technology have developed to a certain height, and even we can completely recreate the earth, but we ignore that our understanding of the earth is only the tip of the iceberg. Judging from the elements of natural geographical environment, soil, atmosphere, water source and biology are indispensable and interrelated to complete various cycles such as water cycle and atmospheric cycle.

Once there is a problem with one element, the whole ecosystem will be affected, and in the long run, it will even face "collapse".

It can be seen that all parts of the earth's ecosystem, such as soil, ocean and biota, have gone through a long evolutionary process before they can live in harmony and become the present earth. Humans only see the results of their own long evolution, put the laws explored in the results into practice, and get the failed results. In the final analysis, it's still too self-righteous.

The failure of Biosphere 2 proves to us that space migration and the transformation of other planets are by no means as simple as we thought. Even if all the data are scientific and correct, there is no guarantee that its ecology can operate normally like the earth. Since it is impossible to recreate a miniature earth environment, does it mean that human beings are trapped on the earth? After all, from this result, we can't survive on other planets, even if we build an artificial ecosystem with the help of external forces.

Although the results of the Biosphere 2 experiment poured cold water on human beings, how can human beings who are brave in exploration and good at persistence give up easily? Instead, it became a booster and ignited the experimental enthusiasm of scientists from all over the world. Since then, more artificial ecosystem experiments have begun to appear.

Let's take a look at the Moon Palace No.1 Laboratory in China, which is an experimental device designed for China to complete its manned moon landing program in the future.

Adhering to the China people's spirit of "intensive cultivation" since ancient times, scientists built Gong Yue No.1 into a "vegetable greenhouse". I have to say that China people will never give up their specialty of "growing vegetables" wherever they go. It is said that a large amount of lunar soil brought back by Chang 'e V just entered the laboratory, and some of it was divided into "experimental vegetables". It can be said that our dream is not only to go to the moon to find Chang 'e, but also to transform Guanghan Palace into our own vegetable garden.

Yuegong-1 is a complete BLSS experimental device, which is called the life support system of space biological regeneration. 20 13 June all installed and put into operation.

But compared with Biosphere 2, it is still very small, with an area of only 36 square meters. However, a large number of vegetables such as lettuce, lettuce and bitter chrysanthemum have been planted in this limited area.

The second is the Mars -500 project led by China and Russia. The program was launched at the Russian National Space Base on 20 10, and six volunteers entered the simulated experimental cabin for 520 days to experience life after going to Mars. According to relevant reports, this experiment was a complete success, and all six experimenters successfully left the cabin.

At present, the construction of the ecological cabin is still limited to a relatively simple and small state, so many people suggest that since it is so difficult to build and carry a large ecological cabin, why not consider directly transforming other planets. In short, although some planets are uninhabitable, we can transform them into habitable planets.

Although this idea is feasible in theory, it is hundreds of times more difficult to realize than building an ecological hut. Take the hot planet "Mars" as an example. If we want to successfully transform Mars, we must implement it in many ways.

First of all, the thin atmosphere of Mars is not enough to block the solar wind and cosmic radiation. If we want to create a suitable atmosphere for it, we need to create an artificial magnetic field. What kind of magnetic field can guarantee the atmosphere of Mars? Scientists say that it is impossible to create such a large artificial magnetic field with current technology and manpower.

Secondly, although there is water in the Martian soil, it is much less than that in the desert of the earth. How many years will it take for the remaining water on the earth to arrive? No one can give an answer.

Moreover, the huge construction cost, in terms of national assets, may be unbearable. After all, there are a lot of materials to be transported before renovation. It can be seen that it is not feasible to transform the planet and copy the earth's environment. At least according to the current situation, human beings are "trapped on the earth".

From the failure of Biosphere 2 to the infeasibility of transforming the earth, these results tell us that although we may have the strength to set foot on other planets in the future, the earth will always be the only home for mankind.

Even though our technology is developing rapidly and the process of external exploration is accelerating, it doesn't mean that we can completely focus on "alien immigration" and completely give up managing the ecological environment of the earth.

According to the viewpoint that the earth is a living body, it must have self-healing function. Even if what we are doing now is really like cancer cells in it, we should not give up on ourselves like this. As long as we change from now on, there is still room for change. Therefore, compared with moving to other planets, protecting the earth is the primary task of mankind. Never put the cart before the horse.
