Mankind's exploration of space has never stopped.
In ancient times, people also had various imaginations of the sky.
It is reported that a long time ago, there were 10,000 households in our country who tied gunpowder to their stools and wanted to go to heaven, but unfortunately failed.
However, with the development of aviation technology today, it is not difficult to understand what the earth is like in the sky.
We already have many ways to "go to heaven" and satisfy our curiosity.
Even the United States has launched plans to travel to Mars.
Although many astronauts have already been to space, the first feeling they have when they come back is that they dare not look at the earth from the outside.
The American Apollo program landed Armstrong on the moon, taking the first steps of humanity.
To this day, some people still suspect that the Apollo program is just a ** of the United States, and the so-called moon landing is just a trick by the United States to fool the Soviet Union.
They just found a place similar to the moon and filmed a **, so that the world would believe that they were the first to land on the moon.
But according to the images, Armstrong's gravity from the moment he exited the capsule was actually reasonable, and the images were not deceiving.
Regardless of whether the American moon landing was real or not,Now people can already land on the moon in various waysChina has also achieved a soft landing from the far side of the moon.
Every astronaut must go through a rigorous selection process before going to space, and there are very few people who can become astronauts.
It is even more difficult to select a few more people who are far ahead of these people, and no matter which country trains an astronaut, it will have to pay a huge price.
Therefore, astronauts are not only carrying their own dreams, but also the expectations of the country.
When Yang Liwei came down from Shenzhou 5, his nose was full of blood.
But for the sake of the country, he couldn't help but say hello to people all over the world, and a few years later, after Yang Liwei's incident was exposed, everyone sighed that it was not easy to be an astronaut.
In addition to this, there are even conspiracy theories that argue that outer space is not what we think it is, that it is actually the other side of hell.
These arguments come mainly from the fact that every astronaut has returned to Earth and has never given a clear idea of what it is like to see the Earth in outer space.
said that he would even be very resistant to answering this questionSo some people speculate that these astronauts are going to outer space with a longing and what they see is an illusion, so they are very afraid.
In fact, based on various hypotheses, the most accurate answer comes from the astronauts.
Many astronauts go to space with the determination to die, because there are many more unknowns along the way than their survival rate.
When they leave the Earth, they lose their sense of security, and all this is related to the cosmic panorama effect.
What is the Cosmic Panorama Effect? Why does this effect make astronauts freak out when they come back from outer space when they talk about Earth?
Frank White, a famous philosopher who once traveled to outer space, once described his horrific experience.
Mr. White himself is a romantic by nature, and he prefers to invest his limited knowledge into the infinite universe, so he is full of enthusiasm to sign up for astronauts.
Unfortunately, the technology at that time was limited, and Mr. White only circled the sky above the earth and returned to the earth.
But even this circle is enough to shock him, why do you say that? Why is it that a dignified writer is so fragile in the face of the earth?
When White arrived above the Earth in a spaceshipEverything is very small.
At the beginning, the majestic mountains were seen from space, but they became thin lines.
Human civilization has become dotted and invisible, and it took thousands of years for human beings to evolve from primitive society to the current civilized society.
In the past few thousand years, human beings have used their ingenuity and ingenuity to build a world that belongs to human beings.
When I got to space, I saw it so small and so insignificantMr. White immediately felt as small as dust.
This insignificance creates an incomparable sense of vulnerability, because human beings feel safe and strong.
And when I got to space, I found that I didn't even have enough dust to call it, the worldview that was built before is now completely collapsed.
The so-called world is so vast that even the earth is just a tiny speck of dust.
Because Mr. White is a philosopher and a writer, his ability to express himself is so good that people who have been to space agree with Mr. White's statement.
To put it simply, when we leave the earth on which we live, we will find that the world we perceive has undergone earth-shaking changes when we go to space.
The world, which was originally very big in our cognition, suddenly became very small in space, and it was difficult for us humans to find a place to stay.
Mr. White had never imagined that human beings and the earth were so closely related until he had been to space, and he only felt that human society and natural society were two completely separate systems.
Human beings can create habitats for themselves according to their own ingenuityBut when I really saw the whole picture of the whole earth, I realized that I was really superficial.
Human beings have no power to resist at all, so they see the whole world defenselessly, like a small ball in front of their eyes.
If the earth were to be compared to an atom, that person would not even be a quark, and even Mr. Wright could not describe the shock in his heart at this moment.
Sandra, an American astronaut, said that even the most staunch atheists have to be grateful to God for all that God has created in space.
It's all amazingThe earth is a small one in the eyes, and who would have thought that there would be even smaller life on it.
It is also this kind of complex emotion, from the shock of seeing the grandeur of the universe to the inferiority of seeing the insignificance of human beings.
There is also the baptism of spirit when they are hit by a huge impact, and it is difficult for astronauts with mixed feelings to accurately express what kind of mood they feel.
It's also a feeling that is hard for those of us who haven't been to space.
Many people wonder if astronauts are the only ones who are highly stressed after rigorous training.
So much so that after going to outer space, I will have such complicated feelings when I see such a scene.
In fact, this feeling is mainly a physiological phenomenon, and it has nothing to do with whether or not to accept high-intensity training, and everyone may have such a shock when they go to space.
Several rockets of the Yutu series in China have been launched, and a space station belonging to China has been fully established in space.
The astronauts who came back from the moon landing said that they did not dare to look back at the earth, why is that?
We are like a mother and a baby with an invisible umbilical cord in between, and as long as we are on the surface of the earth, we are safe.
If you are too far away from the earth's surface, you will be afraidFor example, some people are afraid of heights, because when they stand on a high place, their feet are too far from the ground, and the whole center of gravity will feel falling
The distance between the Earth and the Moon is even farther away, and when astronauts look back, in addition to being shocked by the beauty of the Earth, they will also feel scared because they are too far away from the Earth.
The Earth is several times larger than the Moon, and when you look at the Earth from the Moon, the shape of the Earth is very largeIt is difficult to see such a large shape celestial body on Earth.
How would we feel if we were on the road and looked back and saw a celestial object that almost filled the entire sky?
That feeling of oppression can make us very frightened, because we are used to the size of the celestial bodies in the sky today.
But when we go to the moon and see the earth that big, we will inevitably feel oppressed.
There are also people who believe that the main reason why people are afraid to look at the earth is because the earth is too bright.
When we look at the moon from the earth, the moon is already very bright, but in fact, from the moon, the earth, the brightness of the earth is 50 times that of the moon.
It makes it difficult for astronauts to tell whether it is a celestial body the size of the Sun or the Earth, so dazzling will also feel extremely nervous.
This cosmic effect has put a lot of psychological pressure on many astronauts when they come back, why is this so?
American astronaut Eugene Cernan said that if everyone on Earth experienced the panoramic effect, then the world would not be too polluted.
Because when people really go to space, they will find that the earth is also very fragile, not to mention the human beings who can't show pixels on the earth at all.
If people appreciate that they are so small, they will not start a meaningless struggle because of a little thing, and they will cherish their environment more and love the earth more.
Eugene Cernan is not unreasonable, the environment is now seriously polluted, and sewage discharge is serious.
The earth's environment is not as good as before, and many people will have a misunderstandingIt is believed that the earth cannot be separated from human beings, but the real fact is that human beings cannot do without the earth.
However, there are still a small number of people who can enter space, and most ordinary people do not have the opportunity to experience this effect.
It is said that there are 1,000 Hamlets for 1,000 people, so how will the earth feel from space?
It is not possible to give an accurate answer to this dayIt can only be said that the above views only represent the views of individual astronauts.
Many people panicked on the Internet if it was an astronaut who saw something terrible in space, so they began to worry.
Instead of worrying about these unnecessary things, we should be more concerned about the trivial things in our daily lives.
Live every day well, if there is a real problem in space, then human beings are worried that there will be no remedy, it is better to live the present with peace of mind.
