What is it like to stand on the surface of the moon, looking down on the pitch-black space and looking at the distant earth? In this unique perspective, the earth is not the blue home that we Xi are used to, but a large and mysterious planet.
But it's worth wondering, why does looking down on the Earth from the moon cause fear in the heart, where does this fear come from, and what does it make people see?
The feeling of seeing the Earth from the moon
On Earth, we are all Xi to see the moon as a small silver disc, gently swaying in the night, sometimes rising and sometimes setting, showing different shapes.
The moon is our most affectionate companion in the night sky and one of the celestial bodies we are most familiar with. However, if we jump out of the earth and go to the moon to see the earth, we will find that the earth and the moon are two completely different worlds.
First of all, the Earth will appear unusually large and unusually close to the eyes of people on the moon. Visually speaking, the Earth looks nearly the size of four moons, of course, if you make specific data calculations, the Earth is actually dozens of times the size of the Moon.
The average distance between the Moon and the Earth is 384,000 kilometers, while the average distance between the Earth and the Sun is 150 million kilometers.
In other words, when looking from the Moon to the Earth, the apparent diameter of the Earth is 1.9 degrees, while when looking from the Earth to the Moon, the apparent diameter of the Moon is 0.52 degrees. This means that the apparent diameter of the Earth is 3.65 times that of the Moon, and the Earth is 16 times larger in the eyes of a person on the Moon than the Full Moon. If you are standing on the surface of the Moon, a large area of view will be covered by the Earth.
This huge planet hangs in the dark and vast night sky, giving people a feeling of oppression by giants. What's more, the sight of the earth seemingly hanging overhead all day long may evoke subtle fears in people's hearts.
In addition, the Earth will present an extremely beautiful and colorful scene. The moon is a gray world, with a desolate surface and no vegetation.
It has no atmosphere and lacks liquid water, with only a small amount of frozen water present in its polar regions. The surface is covered with numerous craters and fissures, which are due to long-term meteor impacts and volcanic activity.
The reflectivity of the Moon is only 0.12, that is, only 12% of the sun's light is reflected, and the rest is absorbed. Earth, by contrast, is a blue planet with 71% of its surface covered by water, giving rise to a rich and diverse ecosystem. It has a thick atmosphere that is capable of refracting and scattering sunlight, forming various clouds and meteorological wonders.
The Earth's reflectivity is 0.37, which reflects 37% of the sun's rays and absorbs the rest. Looking at Earth from the Moon, you will witness a blue sphere dotted with white clouds, green fields, red deserts, brown mountains, and black oceans.
These colors are due to the refraction of the atmosphere and the reflection of the earth's surface. The colors of the earth also change with the seasons and the passage of time, and sometimes there are wonderful landscapes such as aurora aurora and solar eclipses. Standing on the moon, you may be amazed by the beautiful scenery, or you may be amazed by the infinite darkness.
Finally, the earth takes on an unusually quiet, eternal atmosphere. There is a unique state of locking between the Moon and the Earth called tidal locking. This is due to the Earth's gravitational pull on the Moon, which makes the Moon's rotation period equal to its orbital period, both of which are 27.3 days.
Therefore, the Moon always faces the Earth on the same side and the other side always turns away from the Earth. This means that when we look at the Moon from the Earth, we can only observe 59% of the Moon's surface, and the remaining 41% is forever hidden in front of our eyes.
Conversely, when observing the Earth from the Moon, the Earth also presents an eternal posture, quietly suspended above the canopy, only slowly rotating, showing different scenes and colors. This tidal lock-in gives a sense of permanence on the Moon or on Earth, as if time and space have been frozen.
What does it feel like to stand on the moon and look at the earth? Perhaps, only those who have experienced it can truly comprehend it. Looking at Earth from the Moon, you will see a huge and beautiful planet, which is your home and uncharted territory.
This angle allows you to experience a sense of awe and fear, but also a sense of loneliness and insignificance. This perspective prompts you to think deeply about the meaning and role of your own existence in the universe, and to think about the past and future of humanity. Looking at the Earth from the moon is an unforgettable experience and an unimaginable one.
Why do you feel fear
There are many reasons why looking at Earth from the Moon can bring fear, a few of which are as follows:
First of all, the Earth is huge relative to the Moon, 49 times the size of the Moon, and this sense of enormity can make people feel oppressive and unsafe. This psychological phenomenon is known as "macrophobia", which is the emotion of fear or disgust towards large objects. This emotion may be the result of human instinct, which feels small and powerless in the face of something more powerful than oneself.
Secondly, the Earth is a blue planet, in contrast to the dark desolation of the Moon, giving a sense of loneliness and helplessness. This psychological phenomenon is known as "autismphobia", which is the feeling of fear or anxiety about isolated or abandoned situations. People who are social can feel lonely and helpless when they lack intimate relationships or social support.
Finally, because the earth is tidally locked, it always faces the moon on the same side, giving the illusion that time and space stand still. This is known as "time phobia," which is the feeling of fear or uneasiness about the passage or stagnation of time. This emotion may come from the human perception of the uncertainty or uncontrollability of time, leading to a sense of confusion and helplessness.
Standing on the moon and looking at the earth is a feeling that very few people can experience, and at the same time it is extremely challenging. This not only tests the physical and technical level of the astronauts, but also challenges their psychological quality and emotional management ability.
In the face of these fears, astronauts need courage and confidence, as well as sound psychological conditioning strategies, to overcome psychological obstacles, complete the mission, and return safely to Earth.
epilogue
From this wonderful vantage point on the moon, astronauts not only saw the magnificent scenery and natural wonders of the earth, but also felt a deep inner challenge. The enormity and loneliness of the earth are particularly strong in the vision of the moon, outlining a scene where the vision and the mind are intertwined.
However, it is precisely this challenge and fear that inspires astronauts to have courage and a desire to explore the unknown. Standing on the moon, they witnessed the magnificence, tranquility and splendor of the blue planet of Earth. This unique perspective not only broadens their horizons, but also evokes a reflection on the small but great place of humanity in the universe.
