Chapter 715 (1/2)

What is the meaning of flying?

There have been many explanations since ancient times, but no matter what kind of explanation, it will be involved with immortals and ghosts.

But this is not the case. A person has left the current world, but he can easily know what is happening in the current world and stop it appropriately.

In a way, it's more like upgrading.

Everyone has heard of dimensionality reduction attack, and the opposite of dimensionality reduction is dimensionality increase.

Flying is to ascend dimension, that is, a person has found a way to go to a higher dimension, and after flying, he can see his own low-dimensional world.

And because he is one dimension higher, he can easily master the low-dimensional world.

From his perspective, the means to destroy a low-dimensional world is dimensionality reduction.

However, civilization is a bug that changes the dimension. The primitive civilization did not know what the sun and stars were. Even in the feudal dynasty, no one could explain what celestial bodies were. They just made calendars with reference to celestial bodies.

Later, after human beings could use telescopes to observe celestial bodies, they had the heliocentric theory, knew what the solar system is and what the Milky way is made of.

After that, humans can go out of the earth, go to the moon and see farther. Finally, humans can send satellites out of the solar system.

In this process, human beings are gradually aware of a marginal problem.

They can explore more and more space, so they think more and more.

Thinking is always faster than doing, so gravity, dimensional theory, relativity, quantum theory, the concept of parallel world and so on have been put forward one after another in the more than 100 years since mankind entered the industrial era.

Then humans began to try in this order, and gradually they could separate their own things from the earth and the solar system.

Then, back to flying, that is, first of all, we can be sure that the human world is a four-dimensional world, but human vision is a three-dimensional sense.

This is why it is difficult for human beings to explain their own world when they want to explain the problem of dimension.

The so-called dimension, to put it bluntly, is that there are several kinds of human existence perception.

It is often said that there are five senses, but if the five senses are classified, they are only three parts.

Shape, sound, smell, taste and touch are people's five sensory organs: vision, hearing, smell, taste and touch.

Among them, vision and hearing are the way to observe the world through external active feedback, which is passive.

Because things from the outside are given to people actively, and people can feel the feedback from the outside as long as they open their eyes and their ears are not blocked or deaf.

Therefore, people accept these two feedback methods passively.

Taste and smell are semi-active. Only when people take the initiative to go to a certain place can they smell some flavor. Only when they take the initiative to send food to their mouth can they know the taste of food.

In this process, the nose and mouth do not know whether it will be fragrant or smelly, and what is the taste of what they will eat.

Therefore, human beings are active in this process, while their own organs are passive.

This is the second category, which can also be called the second dimension.

The third dimension is touch, which is a fully active way of perception. Human beings touch some external things through various parts of the body, and the parts to be touched before touching will make an emergency plan in advance.

So when it comes to hot and cold, human beings will quickly avoid it. When they encounter the feeling of comfort and pleasure, human beings will miss it.
