Why do most people say they feel fear when they look at the Earth from the Moon? What are they afraid of?

In these planets in space, the moon is the closest to the Earth, but also the human early concern about the planet, the ancient times, the moon has been concerned about human beings, and then the technological conditions are more and more developed, humans can explore space, they also began to explore the moon, and now many countries, there are working astronauts in space, these astronauts can also look out at the Earth in space, about the Earth Aerial photography, satellite photography and other types of photos, are quite detailed, many astronauts also said, in space to look at the Earth, they feel a sense of fear.

Many friends who love astronomy, should also see some photos of space planets and will feel from space, the view of these planets is very beautiful, why also feel fear?

In fact, from space to see the Earth, there is no way to see the full picture of the Earth, there is always a side hidden behind, although Knowles the approximate shape of the Earth, still can not view the panoramic view. It is relatively normal for people to feel fear, there is a psychological perception, called arachnophobia, human beings in seeing something too huge, often produce a kind of fear, see the Earth on the moon, which is a behemoth in space, both brightness, and volume, are larger than before.

This is like we see the moon, usually see the moon as very normal, and do not feel anything, but one day, the moon's brightness suddenly increased by dozens of times, and the volume increased by more than ten times, in this case, people will certainly feel some scary. Although the Earth is not the most massive star in the universe, like Jupiter o the volume is far better than the Earth, but the Earth's volume is still relatively large, at least compared with the moon, or has a great advantage. People look at the small moon on Earth for a long time, and naturally change the angle to see the Earth, it will feel some fear.

Another thing, when you see the Earth, people also associate it with the universe, the Earth is so huge in people's eyes, but in the universe, but also just a relatively small planet, it can be seen how vast the universe is, so far mankind has not been able to thoroughly explore the universe, maybe the end of human civilization a life, there is no way to complete. This also allows people to have more speculation about the universe, the universe in the end there is no unknown civilization, human beings in the universe is just small dust, the Earth is just so, so what is the world we live in?

What is the meaning of human exploration? Where is the future of mankind? Seeing the earth in space, it seems to feel as if everything in this world is not so important.

Looking from space, this is also the first time that humans have come to observe the planet they have been living on from the outside. Before humans were able to enter space, we had never been able to observe our planet so comprehensively. After seeing the Earth, one can't help but think that one has always lived on such a huge planet, which is also too surprising.

The earth is so huge that it is indeed beyond human imagination. This allows people to recall more things related to life although humans can explore the universe, for so many years, humans have not even explored the earth they live in to understand, whether it is the sky or the earth, there are many things unknown to humans. Many people have a wrong perception of the Earth, that is, we feel that the protection of the environment and so on, is to protect the Earth, but many experts pointed out that humans have not realized the true horror of the Earth.

The history of mankind is only a very short chapter compared to the history of the Earth, and perhaps only after people have seen the immensity of the Earth from the Moon can they realize how naive their thoughts are. The Earth does not need our protection at all, and what humans call protecting the environment is protecting humans themselves.

Because of the ability of the Earth, once it reaches a certain critical point, it will begin a comprehensive reshuffle, now like earthquakes, tsunamis, and other natural disasters will still bring great harm to humans, human technology is not yet able to predict such disasters, so in front of the power of the Earth, humans are simply unbeatable, only to identify this, to maintain the right attitude to the environment we now live in. The earth does not need human protection, but rather humans should worry about themselves.
