Chapter 174: Four-Dimensional Space

After saying this, this unknown existence also added a sentence at the end, "You just call me Taihao." ”

The word Taihao has a special meaning in the earth's civilization. Taihao, also known as Fuxi, is the ancestor of mankind in Chinese mythology and legend.

"Space radio is known to have some kind of automatic translation function, which can automatically translate information into the most appropriate words based on the data in my head. Since it translates the word into the Taehao in my mind, there must be a reason for it. ”

"However, how can it be the Taihao civilization, how can it be the Taihao civilization!" When he heard this word, Xiao Yu was shocked in his heart.

"As far as I know so far, the Taihao civilization has existed in the galaxy for at least hundreds of thousands of years, and hundreds of thousands of years ago, they imprisoned the white dwarf alien beast, and the white dwarf alien beast is the third alien beast in their number, which shows that there were number one and second alien beasts before it, and how many years they have existed is even more unpredictable, but this guy, it has just come from the Big Magellanic Nebula? How could it be the Taihao civilization? ”

"It's lying to me? What is its reason for doing so? Moreover, if you really want to lie to me, why do you want to say the name Taihao? Wouldn't it be more logical to just make up the name of a civilization? Xiao Yu thought quickly.

"You, have you been to the Milky Way galaxy before?" Xiao Yu asked cautiously.

"Oh? Do you have any questions? Tai Hao asked with interest, "I have just come to the Galactic Star Field less than 10,000 years ago, the emptiness of the Milky Way is beyond my imagination, you are the first intelligent creature I have encountered in 10,000 years." ”

"Empty?" Xiao Yu smiled bitterly, thinking secretly in his heart, "Where will it be empty?" Since leaving the earth. I've come across so many civilizations...... Kindness? Wrong. Maybe the galaxy is really empty, and it's only because of someone's covert manipulation that I encounter so many civilizations. ”

"That's right." Xiao Yu thought for a moment and said, "I once encountered a powerful alien beast before, and it said that it was the Taihao civilization that imprisoned it on the white dwarf. ”

"That's normal." Tai Hao replied with a smile, "Just like a technological civilization, there is a technological civilization in the Galactic Star Field, and there is also a technological civilization in the Big Magellanic Galaxy. Taihao civilization can exist in the Big Magellanic system. Naturally, it will also exist in the Milky Way galaxy. ”

"It's like this...... Xiao Yu was stunned for a moment before he said: "It turns out that Taihao civilization is the same as scientific and technological civilization, and it is a general term for a certain civilization. ”

"Yes." Tae-ho replied, "But it's different. According to your description, the Taihao civilization that the alien beast said in his mouth. It seems to be the D-type Taihao civilization. I belong to the Type C Taihao civilization. I don't know if that D-type Taihao civilization still exists, if it still exists. I want to go over and fight it. ”

"What type of civilization is Taihao civilization? and technological civilization. What is different about Alien Beast Civilizations? Xiao Yu asked.

finally encountered a powerful civilization, and this civilization showed some kind of kindness to himself, Xiao Yu naturally didn't want to let go of this opportunity.

During this period of getting along, every piece of information Xiao Yu got could save his life for a long time to come.

"Taihao civilization. It's just a civilization that tried to evolve into a seventh-level civilization but failed. My predecessor was a sixth-level alien beast, and in the process of trying to evolve into a seventh-level alien beast, I encountered failure. And that's what it looks like. The message sent by Taihao became vicissitudes: "Who can say clearly about the things in the universe." Destruction means rebirth, and after rebirth, it is destruction, Taihao civilization is a civilization that is on the verge of destruction, so it is called Taihao. ”

"I don't really understand." Xiao Yu said.

"You don't need to understand too much. When you get to this stage, you'll understand. Taihao sighed, "Your type of existence is a bit interesting, but don't worry, your type of existence has no reference significance for me, and I won't hurt you." Hey, hundreds of millions of years have passed, and it's good to have someone to talk to. ”

Xiao Yu thought silently.

"There is a great possibility that the unknown existence that has been silently watching me behind my back is the Taihao civilization that imprisoned the white dwarf alien beast and even forced that earth girl to commit suicide. But...... Since it is a Taihao civilization, it is impossible for it to be a seventh-level civilization, and it is unlikely to be much stronger than this Taihao I have encountered now, in other words, it does not have the ability to manipulate the current Taihao. In this way, there are about three explanations for my situation. ”

"First, it's lying to me for some unknown reason."

"Second, if what it says is true and the information is correct, does that mean that our encounter is really just a coincidence, and the manipulator behind it does not actually exist? But it's okay to have a coincidence, so many times, is it a coincidence every time? ”

"The third type is the Taihao civilization that imprisoned the white dwarf alien beasts. It personally came out to save me from the information storm. ”

"The second option is the most likely. There is not enough information to continue the analysis. Hey, let's take it one step at a time. Xiao Yu came to a conclusion.

Xiao Yu asked another question: "Are you a Type C Taihao civilization?" What does the Taihao civilization rely on to divide types? ”

"This is just the division of scientific and technological civilization, and I don't know the specific details." Taihao replied, "The universe is vast, but in this vast universe, no one knows whether there is a seventh-level civilization or not. At least, in my more than 200 million years of life, I have not seen any seventh-level civilization, or even heard of it. After evolving to the peak of the sixth-level civilization, I chose space as the direction of breakthrough, but I still failed, so I now exist in a semi-three-dimensional and semi-four-dimensional state. I'm attached to this three-dimensional space, and I'm in four dimensions at the same time. Kindness...... In other words, if we compare two-dimensional space with three-dimensional space, it is as if creatures that have not yet evolved the ability to fly live on the surface of a planet. They are attached to the two-dimensional space on the surface of the planet, but their bodies are in three-dimensional space. Anyway, my type is called the C-type Taihao civilization by those technological civilizations. ”

This passage is very easy to understand, and Xiao Yu understood it all at once.

"You...... Have a fourth dimension, but can't move above the fourth? Xiao Yu asked with some hesitation, "It's like a creature that hasn't evolved the ability to fly and can't leave the surface of the planet?" ”

"Clever, that's it." Tai Hao replied with appreciation, "I can't return to the three-dimensional space, and I can't completely go into the thinking space. The shadow you are in is the projection of my four-dimensional body in three-dimensional space. ”

The four-dimensional space only exists in mathematics, and it is basically impossible for human beings, as three-dimensional creatures, to have a relatively intuitive understanding of the four-dimensional space. However, we can use the analogy of two-dimensional space and three-dimensional space to explore the mystery of four-dimensional space.

Dimension is just a concept in mathematics that describes the need for several parameters to locate the position of a point in a space. One parameter is one-dimensional space, and three parameters are three-dimensional space.

Suppose a space is a straight line, and it is clear that it only needs one parameter to locate a point on it, so it is a one-dimensional space. Two-dimensional space is a plane, because two coordinates are needed to locate a point on top of this plane.

In our three-dimensional space, we need three coordinates to locate a point. In four-dimensional space, four coordinates are required.

"Taihao said that it has a fourth dimension, but it can't move above the fourth dimension, so it can probably be understood like this......" Xiao Yu thought, "It's like a plane creature, it only has two dimensions, length and width, and no third dimension of height." Suddenly, it had a height, and it evolved from a two-dimensional creature to a three-dimensional creature. However, its evolution is not complete, it cannot leave this plane, it has heightened, but it cannot jump, it cannot crouch and stand up...... Its third dimension is fixed and cannot be changed, and this situation is somewhat similar to that of Taihao. ”

To put it simply, Taihao's current situation is like a car in three-dimensional space, it can turn left and right, but it cannot be raised or lowered. Although it has a third dimension of height, it can only move in the two-dimensional space of length and width.

Taihao has a fourth dimension, but he can still only move in three-dimensional space.

"Four-dimensional space, what does it look like?" Xiao Yu asked cautiously.

"I can't describe this to you in detail. I can give you a feel for a moment, though. Tai Hao replied, "Although the four-dimensional space is wonderful, after looking at it for a long time, it is just like that. ”

"Really?" Xiao Yu's heart became excited.

"In our universe, three-dimensional is the mainstream. Matter exists in a three-dimensional state. In the four-dimensional space, there is nothing but emptiness. Taihao sighed and said, "You already have a four-dimensional perspective, let's look at your shijie again with a four-dimensional perspective." You only have five minutes because I don't want to expend too much energy for you. ”

At this moment, all the instruments under Xiao Yu's control seemed to be in a trance.

Xiao Yu heard what Taihao said, but Xiao Yu didn't pay attention to it. Because, Xiao Yu was completely shocked by the magical scene in front of him.

What was presented in front of Xiao Yu was a bizarre and indescribable shijie. (To be continued......)
