Voyage of the Stars.

Chapter 719 A Digital Star Map

Because the initial information interaction between the two civilizations was only in this form. There was no such thing as sending a sentence or a word. Even if you sent it, the other party would not be able to recognize it.

Just like when one person sends a sentence to another person, it is not actually a sentence. At the bottom is a series of binary numbers. It is the computer that translates this series of numbers into a sentence. This is the translation in the corresponding dictionary.

The same is true for communication between civilizations. We must know what the other party's numerical values ​​0001110110 correspond to and what words these things correspond to in order to understand the other party's writing system. It is true that physical phenomena are the same language of the universe, but the signals between civilizations cannot carry complex physical phenomena. They only have 0 and 1. Therefore, if we want to communicate faster, we must use physics and mathematics together, and it is best if we have our own display devices and spacecraft facing each other to show each other our corresponding words and objects.

Just like what happened between humans and the Nair civilization back then.

But now humans and the unknown signal source do not have such conditions, so it is difficult to communicate.

It is difficult to communicate, and there is a risk of the other side discovering the large fleet. What should we do?
Yue Yuan, who had just come from the cockpit to the hall where the scientists were, saw this situation and two choices came to his mind: one: destroy the target, two: turn around and leave before the other party discovers the human fleet.

It's not that they are afraid, but they are cautious. Humans don't want other civilizations to know the reason why they come here. They don't want to expose their purpose of looking for the small universe left behind by the pioneers. That is a small universe left behind by a sixth-level civilization. Humans certainly don't want other civilizations to know about this opportunity.

With the mutual discovery detection nature of tachyon detection, a fight would mean a war between two civilizations. Yue Yuan did not act impulsively, but first understood the situation: "There is only one signal source?"

"Yes, General Yue, it has been confirmed again and again, there is only one." Zhao Youqin replied.

Yue Yuan nodded, but did not continue the conversation. Instead, he used his brain chip to open the virtual UI, connected to another department's call, and asked, "What's going on over there?"

His voice was transmitted through the communication equipment he carried on his body to another Saturn battleship, which was the flagship of the human Third Fleet. The detection spacecraft team that detected the tachyon signal was under the jurisdiction of the Third Fleet.

As soon as the voice came out, the voice of Bu Guiyu, commander of the Third Fleet, came from Yue Yuan's communication device: "The detection spacecraft team has approached. The target is a detection spacecraft. The target has not yet discovered our fleet. According to the latest intelligence, the target detection spacecraft is approaching our fleet at 8 times the speed of light, with an angle of degrees. Our detection spacecraft team has sent a tachyon signal response to it, but the target still repeats the previous signal form and has not responded to our communication information."

"We didn't find any detection spacecraft around it! Based on this, we believe that it may not be a detector, but a broadcasting spacecraft with other purposes! As for its purpose, we may need to decipher the tachyon signal information it sends out to find out."

"Okay, I got it." Yue Yuan said, and then he pondered for a while before continuing: "Let our exploration spacecraft keep an eye on it. At the same time, the Third Fleet will follow the large fleet and turn to avoid its direction. Also, let the exploration spacecraft team be prepared to destroy it."

The purpose of the large fleet's evasive turn is to prevent the other side from discovering the human body, but if the target detector has warp detection equipment, it will still discover the warp traces of the large fleet, and thus indirectly discover the direction of the human body, so it is still necessary to be prepared to destroy it.

"Understood! We have ordered the exploration team of the Tianquan civilization to conduct in-depth exploration of the target location. If we are sure that there are no other spaceships in the space behind it, then we can basically be sure that it is not a probe but some kind of spaceship broadcasting system." Bu Guiyu expressed his judgment.

Yue Yuan nodded secretly. He understood what Bu Guiyu meant when he said it might be some kind of spaceship broadcast.

The tachyon technology of the fourth-level civilization is not suitable for cosmic broadcasting because of its short range. For example, if human tachyon technology is used for broadcasting, it is not as far as conventional electromagnetic wave broadcasting. However, the advantage of tachyons is also obvious, that is, it is almost instantaneous within its effective range. Therefore, the fourth-level civilization can use this method to broadcast in the cosmic region, that is, to launch a warp speed navigation probe with tachyon launch function in all directions of the starry sky, and then let it broadcast to the area it passes through like a signal source that continuously sends signals.

It is just like throwing a light source that shines according to a certain pattern into the dark abyss, using this method the existence in the dark abyss can express what it wants to say.

This method of shouting to the universe is much more efficient than the speed-of-light electromagnetic waves. Humans have also thought of the broadcasting form of a Level 4 civilization, but because of the need to hide themselves, humans have not built such spacecraft.

After hanging up the phone with Bu Guiyu, Yue Yuan once again turned his gaze to the scientists present: "Any progress?"

"It is impossible to know what the other party means unilaterally, but we are trying to layout these numbers in graphic and spatial terms," ​​Zhao Youqin replied.

The computing power of Tianhe Light is very powerful. As soon as Zhao Youqin replied, a large number of numbers appeared in front of everyone.

First up is a bunch of simple two-dimensional flat typography.

Unfortunately, humans can see nothing but a bunch of garbled numbers.

Next was the layout of these numbers in three-dimensional space. There were also many of them. One of them was highlighted by the "Light of the Milky Way", and everyone's attention was naturally attracted to it first.

It doesn’t matter if you don’t look at it, because once you look you’ll see a picture.

To be precise, it is a three-dimensional pattern composed of a large number of densely packed numbers 0, 1, and 2.

It seems that this signal does not need to be translated at all, its content is just this picture?
Everyone knew what this picture was because it was so obvious that this dense group of numbers piled together formed a star system pattern. The stars in the pattern were made up of a pile of 1s, the planets were made up of a pile of 2s, and the vacuum between the planets was filled with 0s.

Apparently, this was a digital drawing of a star system.

Not only that, in another holographic screen there is another star map made up of a bunch of 0s, 1s, and 2s, but this map is not a star map within a star system, but a star map of a star field somewhere. The 0s in the image still represent the vacuum of the universe, and a bunch of 1s piled together represent stars, but the 2s here are obviously not planets, because they appear between each star, and it looks like a line of 22222222222222 replaces the 0s representing the vacuum and is connected to a bunch of spherical 1s representing stars at both ends.
In this way, humans immediately understood the meaning of these 2222222222, because the number of 2s connecting the stars is different, they form strings of 2s of different lengths. Obviously, these 2s here represent the distance between the stars.

Humans do not know how much distance a number represents, but they can think of it as a distance unit. There are as many 2s as there are distance units. The result can then be proportionally compared to one's own star map, and star fields with the same distance ratio between stars can be found. In this way, one can compare which star field in the real universe the star field represented by this digital star map corresponds to.
