In the process of exploring the starry sky, human beings have become more and more aware of the dangers of the universe to our human existence, as well as a series of physiological problems that astronauts in space need to face, and all of this makes it possible for human beings to be trapped on the earth.
After astronauts stay in space for a period of time, the physical changes are very obvious, and they are prone to suffer from symptoms such as eye muscle syndrome and memory loss, what causes this?
And what is it about this that makes it impossible for humans to escape the earth?
Physiological problems in space.
After astronauts stay in space for a period of time, their bodies will change to a great extent, and some physiological functions will begin to develop in the direction of being more adapted to the cosmic environment, while some functions will have many problems because of being in weightlessness for a long time.
Recently, Russia's Galaxy Space Corporation found that in the six-month microgravity simulation environment in the capsule, astronauts' eye muscles have a special symptom, this symptom is called "eye muscle syndrome", which is characterized by weakened eye strength and decreased vision during space, and even some astronauts will have "astronaut parity syndrome" during space.
After the astronaut returns to Earth, these symptoms will recover naturally, but the appearance of this symptom is still a very serious thing, especially if the astronaut has "astronaut parity syndrome", then he will not be able to judge his own casualties after returning to Earth, which is very detrimental to the process of human exploration of the universe.
So how is this symptom caused?
In 1985, an aerospace medicine expert named Joseph T. Melugin in the United States found through a series of studies that when astronauts are weightless, the eyeball will gradually become brittle, and the elasticity of the entire eyeball will be seriously damaged, which will lead to astronauts suffering from "eye muscle syndrome".
Melugin also found in his later research that the human eye is a double spherical structure, and in a weightless environment, the structure of the eye will be gradually destroyed, and different structures will be damaged differently.
There is a certain correlation between the hyaline body inside the human eye and the information sent by corneal neurons, and in a weightless environment, the probability of neuronal destruction is extremely high.
Neurological function in astronauts declines.
The brainstem neurons in the human cerebellum play an important role in regulating the movement of muscles and the eyeball, and this part will be seriously damaged in the weightless environment, resulting in a significant increase in the degree of freedom of the eyeball, and with the change of the movement state of the cerebellum, the degree of freedom of the eyeball will continue to decline, resulting in a series of problems such as vision loss and ophthalmomuscle syndrome.
After this study, the United States has adjusted the exercise methods of astronauts in space on a large scale, aiming at astronauts suffering from eye muscle syndrome in space, if human beings really want to stay in space for a long time to explore the starry sky, human beings must carry out regular exercise on earth for this symptom.
And recently, Soviet researchers have also discovered that there is a kind of cell called "neural prototype" in the astronaut in the weightless environment will be destroyed in large quantities, in the human body in the weightless environment for a long time, the human nerve will become very fragile, human senses will also be greatly affected.
In addition, there is also a type of "memory cell" that will be greatly destroyed by the weightless environment, and the number of human memory cells will show a sharp decline, in addition to this, the human sensory cells will gradually become dull.
That is to say, after a human being is in a weightless environment for a period of time, his nervous function will be greatly reduced, and his senses will also be greatly affected, which is a very unfavorable thing for human beings.
Humanity will eventually be "trapped" on Earth.
Therefore, if you want human beings to explore the universe for a long time, you must make his body adapt to the weightless environment, so as to make a certain transformation of the human body, but human beings cannot rely on their own strength to bring about the transformation of the body, so in the end, human beings may only be able to stay on the earth for a long time.
We can look at this from another aspect, the human skeleton is because it is in the gravity environment for a long time, so it will maintain its current form, if the human skeleton has to adapt to the weightless environment, then it will develop an extremely fragile state, which is also very unfavorable for humans.
In addition, there are sufficient nutrients on the earth for human use, and human beings have a large amount of energy that can be used on the earth, which are incomparable to the planets that human beings cannot reach, so human beings should still have self-knowledge and stay on the earth forever, which is the most beneficial for human reproduction.
epilogue
We humans should look at our homeland with gratitude and settle down on this blue-green planet for the benefit of human reproduction.
As for astronauts, they work in space to contribute to the healthy presence of humanity on the planet in the future, and we are all grateful for their contributions.
