Astronauts' brains changed dramatically after their space flight, so humans can't move into space?

Since industrialization, with the development of human science and technology, going out of the earth is a goal of human beings now, including space exploration, human migration and other goals are being carried out all the time. And when implementing these plans, astronauts can be said to act as inside? Important role? Especially when you go into space, you can't do it without astronauts. Over the years, after human beings have the ability to enter space, they are also worried about the physical changes of astronauts, because from their changes, we can see the problems that human beings will face in the future.

Therefore, the scientific community has strengthened the research on a change of astronauts before and after entering space, and the latest explanation published by the journal Science Progress has indeed discovered a change of astronauts, which has aroused many people's concerns.

The astronauts' brains have changed significantly

According to scientists' long-term research, after the astronauts stayed in space for a long time, there has been an obvious impact on the brain structure, which is really a bit serious and belongs to a great brain change.

Scientists studied the brain structure of 11 astronauts from Australia, Russia and other countries, among whom the average continuous stay time was 171 days. Scientists imaged each of them three times, once before flying into space and twice after returning to Earth.

It was found that before and after they entered the International Space Station, the distribution of white matter and gray matter in the brain changed because they were under zero gravity for a certain period of time, and the ventricles were enlarged, and the cerebrospinal fluid in them increased. Although this change has returned to normal in the later period, it will take seven months to live on the earth before it becomes normal. What is the reason?

Experts believe that the nervous system adapts to weightlessness in this way and increases the workload of the brain area that controls movement, which is why this situation is caused. But its changes have told us that human beings may not be suitable for living outside the earth.

humans can never live outside the earth? Unable to leave the earth?

indeed, judging from the changes of astronauts, this is still in the International Space Station. What if we change it to what we call it? Does the second earth, Mars, mean that this problem may be more serious? It's right next to human beings. Can we go? Although mars will not be serious? Weightlessness? problem

But Mars is not exactly the same as the Earth, and it can be directly inhabited. If astronauts go there, the external conditions may also have an impact on astronauts. In the national space station, it can be regarded as a change of astronauts because of the change of environment.

Therefore, the environment of Mars may also lead to changes in various organs of human beings. The change of astronauts in the International Space Station is a wake-up call for human beings, that is, if human beings can't change Mars, then human beings may not adapt to it, not to mention that Mars is a planet today. Abandoned? The planet, so humans may never leave the earth, unless Mars is transformed into a celestial body suitable for human beings to live completely, which is the most basic situation, otherwise humans will never be able to live outside the earth and move to Mars, that is? Arabian nights? , can't get rid of the earth.

Can humans transform Mars?

According to scientists' public statement, it is not impossible for humans to transform Mars. It may take a little longer. According to scientists, transforming Mars into human beings? The second earth? It will take 2-3 years. After this time, humans can live on Mars without wearing spacesuits, so it is still feasible.

It's not without change that the temperature of Mars is close to the Earth and it is suitable for human beings to live in the future. It depends on whether human civilization can continue in this period, because the earth's ecosystem is already very bad.

from the situation since 22, we can also see that high temperature, drought and heavy rainfall are raging around the world, and their impact on human beings is obvious, but human beings have not yet? Qi Xin works together? To change the ecological environment of the earth, on the contrary, it is aggravating the impact of the ecosystem and causing more serious damage. So the deadly ecosystem impact is already affecting human beings. If it continues, the critical point of climate, mass extinction and other problems all appear, then the possibility of human beings trying to change the ecosystem will be gone.

So, on the whole, people do think that there is a way to transform Mars into the second earth, but the time may not be consistent with the current degree of destruction of the earth. If the damage is intensified, people may not be able to live with the earth before they reach Mars.

At the same time, the brain changes of today's international astronauts once again remind mankind that in order to live or live outside the earth, it is necessary to meet the ecological environment of the earth, so that human beings can live normally, otherwise, in the future, human beings will go to other planets, which may be more than just similar to? The astronaut's brain has changed significantly? The problem may be more serious or even fatal in an instant.
