With the coming of the third scientific and technological revolution, people’s exploration of the universe has become more and more important. There are more ambitious goals, including the great plan of human migration, which was kicked out in the last century. In the process of implementing this plan, astronauts must have played an important role. Over the years, human beings can gradually transport astronauts to outer space for investigation through manned spacecraft, and scientists are always paying attention to these problems The physical condition of the astronauts going to space, in order to judge or infer whether human beings are suitable to live in outer space.
The author just looked up the scientific journal and saw its latest explanation. When astronauts return to earth from outer space, their body functions have changed, and the biggest change is the brain. The brain is a very wonderful structure. During the six-month stay in space, the brains of these astronauts changed consistently. After several times of MRI screening, the scientists found that the distribution of white matter and gray matter in the brain changed completely, and the ventricles expanded a lot. Of course, the cerebrospinal fluid in them increased.
Maybe many people are at a loss when they see this place. They don’t know what it means at all – what I want to explain most is that the human brain will change a lot because of losing gravity in outer space for a long time. However, once they return to earth, after these astronauts return to China for more than seven months, they will be screened by MRI, and medical scientists will find out what they are doing The brain has gradually returned to a normal state. According to the most common medical knowledge, the nervous system adjusts itself and brain to make human beings and brain adapt to the sense of weightlessness, and increases the workload of brain region control, so this kind of physical change appears.
Therefore, the author makes a reasonable guess here, if all or part of human beings migrate to outer space, then whether this part of human brain will also change like these astronauts. If so, can human beings withstand such changes? According to the available data, many scientists or astronomers believe that Mars is the most suitable second planet to live on. So, will human migration to Mars also lead to the problem of uncontrolled weightlessness?
Mars and the earth are never the same, especially in terms of gravity, which means that ordinary people can not live directly on Mars. As long as the environment is different from the gravity of the earth, the human brain must change. But now that the astronauts have never gone to live on Mars, it’s hard to know if the same changes will happen to the brain, or other organs. If it is based on the current reasonable speculation,
Human beings want to go to Mars for transformation, which is basically impossible to achieve, unless they can artificially transform Mars into a body with gravity, and completely suitable for human habitation. Some people may wonder whether it is impossible to transform Mars, but according to scientists published in the journal, it is not impossible. It just takes a long time. To be specific, I will not elaborate here.
From 2020, we will see the epidemic situation, typhoons, floods, tsunamis, earthquakes and other natural disasters, which may be warning mankind. The destruction of ecosystem by human leads to the extinction of natural balance. If it exceeds a certain critical point, it is possible for human beings and all living things to perish. Therefore, in the case of still not having the ability to transform Mars and adapt to Mars, human beings should really protect nature, not for others, but also for themselves.
