"The broadcast has been going on for five minutes and is still going on!"
Tomoko pointed to the window and continued: "Actually, the broadcast information is very short. It lasts for so long because it uses different languages. Now there are tens of thousands of languages..."
"Oh, now there are 100,000 species!"
"Is this broadcast to all small universes?"
Cheng Xin asked.
"It must be, but who else could it be against? Using such a large amount of energy should be important information."
Guan Yifan replied for Tomoko.
"Is there a Trisolaran and Earth language?"
Liang Bing also asked.
"No."
Tomoko replied.
At this moment, several people instantly understood that this was the life and death book of a cosmic civilization.
Now, tens of billions of years may have passed in the universe, no matter what the content of the broadcast message is, if the language of a civilization can be listed in the broadcast message.
Then, there are only two possibilities. One is that this civilization still exists; or, this civilization existed and survived for a long time, and its culture left a permanent mark on the universe.
Second, this civilization has been considered to no longer exist, so the language of this civilization does not appear in the broadcast content.
The river of symbols flows mightily through the information window, and has been broadcast in 200,000 languages, 300,000, 400,000... until one million languages, and the number is still increasing.
Trisolaran language and Earth language still have not appeared.
However, when the number of broadcast languages had increased to about 1.3 million, Tomoko suddenly shouted: "Three-body!"
He pointed at the display window with one hand, and a message in three-body text flashed past in the window. It was impossible for several people to see it clearly, but Sophon could.
After a few seconds, Tomoko shouted again: "Earth!"
When the language types of broadcast information reach 1.57 million, the broadcast ends and the scrolling display in the information window disappears.
Only two messages written in the three-body and earth languages were still displayed.
At this moment, Liang Bing didn't have any special mental activities. After all, she didn't belong here.
However, although neither Cheng Xin nor Guan Yifan could see the content of the message clearly, their eyes were still blurred by tears.
On the last day of judgment of the universe, both civilizations, the Earth and the Trisolaris, will still exist.
Regardless of whether they can make it to the end, the two civilizations of Earth and Trisolaris seem to be able...
They know that language and writing evolve very quickly. If two civilizations have existed for a long time, or even still exist now, their writing must be completely different from what is shown now, but for people in the small universe to understand, Only ancient characters can be displayed.
Compared with the total number of civilizations that have ever existed in the universe, 1.57 million is a rather small number.
In the long night of the Orion Arm of the Milky Way, two civilizational meteors passed by, and the universe remembered their light.
After everyone calmed down, Tomoko also helped them read the content of the message carefully. The content written in both languages was the same, very brief:
“Return Movement Statement: The total mass of our universe is reduced below a critical value, the universe will transform from closed to open, the universe will die in eternal expansion, and all life and memory will die.
Please return the mass you took away and only send the memory to the new universe. "
Several people looked away from the return to sports announcement and looked at each other.
They all seemed to see the dark prospect of the universe through each other's eyes.
In the eternal expansion, all the galaxies will move away from each other, until they are out of sight.
At that time, from any point in the universe, there will be darkness in all directions.
Stars will extinguish one after another, physical matter will disintegrate into thin nebulae, cold and darkness will rule everything, the universe will become an empty tomb, and all civilizations and all memories will be buried forever in this boundless tomb. , everything dies forever.
In order to avoid this future, the only way is to return the matter in a large number of small universes created by different civilizations to the large universe.
But if we do this, we will not be able to survive in the small universe, and people in the small universe will have no choice but to return to the big universe. This is the return movement.
"How many civilizations would be willing to give it back?"
Several people are worried about the success rate of returning to sports.
After all, before they fell into the black realm or entered the small universe, the environment of the big universe was already very bad.
In such a large-scale cosmic environment, every space voyage is still able to escape the difficult sense of sight, encountering areas that have been reduced in dimensionality, and falling into black areas at every turn...
Today, tens of billions of years may have passed in the universe, so what will it look like now?
Will it really be true, as Tomoko guessed, that the moment a few people step out of the small universe No. 647, they will die instantly in the dangerous environment of the big universe?
Several people dare not imagine it, and they cannot imagine it at all.
"So, what's your decision?"
After giving several people enough time to think, Tomoko spoke again.
The ownership of small universe No. 647 does not belong to her, but to Cheng Xin, Guan Yifan, and Liang Bing.
Naturally, it is up to the three of them to decide whether to respond to the return movement and return the mass of small universe No. 647.
However, this choice, which seems to test human nature very much, doesn't seem so difficult once you think about it carefully.
At this moment, in a certain small universe, Zhang Heng in the virtual world also received the broadcast, and his decision was to return the mass of the small universe.
His current decision is also the decision made by Zhang Heng of the real three-body universe in the last zeroing cycle.
After all, the possibility of death and the certainty of death are two very different options, and that's a good choice.
But he won't be the first to return it.
"Since the outcome cannot be changed, the universe will die in eternal expansion, and we will all die that day."
In the small universe No. 647, after Sophon asked, it was Guan Yifan who was the first to express his stance: "Being modest is a lifetime, being vigorous is also a lifetime."
As he said before, he studies the universe with a diameter of 16 billion light-years. He does not want to spend his life on a planet with a diameter of only more than 10,000 kilometers, let alone a planet with a diameter of only more than 1,000 kilometers. Spend your life in your own little universe.
"I agree."
Cheng Xin quickly expressed her position and said that what Guan Yifan said was in line with her wishes.
Not to mention Liang Bing, she has only one purpose, and that is to return to the known universe.
And this goal is simply impossible to achieve just by staying in the small universe No. 647.
Therefore, no matter how dangerous the outer universe was, she was eager to go out and find her way back.
Otherwise, once the return movement officially begins and the universe restarts, she cannot guarantee what she will become.
The decisions of several people were unanimous.
Afterwards, Sophon immediately passed the control system of Universe 647 and manipulated the door of the small universe in the large universe.
According to Zhang Heng, this door is the anchor point of space.
The door moves rapidly through the universe, looking for a world suitable for a few people to live in.
However, the communication between the door of Microverse 647 and the Microverse can transmit very limited information and cannot transmit images.
Only an assessment of the environment can be sent back, which is a number between minus ten and ten that represents the environment's survival level.
Only environments with levels greater than zero can humans survive in them.
The door made tens of thousands of jumps and moves in the universe. This process took three months, and only once detected a level three environment. Sophon had to admit that this was the best result.
"Level 3 environment is very harsh and dangerous!"
After getting the results, Tomoko said to several people.
"We're not afraid, let's just go there."
Cheng Xin answered firmly, and Guan Yifan and Liang Bing also nodded to Tomoko.
Then, Menzai Exit also appeared in Universe 647.
This door is the same as what several people saw on Blue Star. They also came in through a door when they came in before. It was a rectangular shape drawn by glowing straight lines, but it was much larger than the one on Blue Star. It may be for the convenience of material transfer.
When the door first appeared, it was not connected to the larger universe, and any matter could pass through it to the other side.
When the sophons reset the parameters of the gate, the matter that passed through the gate disappears, and they will appear in the larger universe.
Then, Universe 647 began to return matter to the larger universe.
Obviously, they were somewhat desperate and began to return the mass of the 647 small universe so quickly.
This exit coupled with the return of mass means that they can never go back. Even if they want to go back, there will be no second small universe to turn back to.
"The small universe itself has no mass. Its mass comes from the matter brought from the large universe."
"Among the hundreds of small universes that Trisolaris has ever created, No. 647 belongs to the smallest category. It took away about 500,000 tons of matter from the large universe, which is equivalent to the load of a large oil tanker in your century AD. The amount is truly insignificant on a cosmic scale.”
Before returning the mass, Tomoko explained this to several people before officially starting.
Material transport begins with the soil.
The fields had not been sown since the second harvest, and the robots used farm carts to load the wet soil. When they arrived at the door, two robots lifted the cart and dumped the soil into the door - after passing the rectangular plane. Finally, the soil disappeared.
The soil was moved very quickly. After three days, there was not a grain of soil left in the small universe, and the few trees around the house were also transported through the door.
After the soil disappeared, a metallic ground appeared in the small universe.
The floor is made up of smooth metal plates, reflecting the sun like a mirror.
The robot removed the metal plates from the side of the floor and pushed them into the door piece by piece.
Under the ground that was lifted up on one side of the small world, a small spaceship was revealed.
This spacecraft is only a dozen meters long, but it condenses the most advanced technology in the Trisolaran world.
It is designed according to human ergonomics on earth, can accommodate three passengers, is equipped with two power systems, nuclear fusion and curvature drive, and has a mini ecological circulation system and hibernation device suitable for humans.
Perhaps to make it easier to pass through the door of the small universe, its shape is elongated and streamlined.
This spacecraft was originally conceived to be used by people from Universe 647 when they entered the new universe. It could last for a long time before finding a suitable living environment in the new universe.
Now, they will ride it back to the big universe.
After the small universe had basically returned all its mass, there was only a slender small spaceship and three people floating beside the ship in the space of the small universe.
Tomoko held a metal box, which was what they wanted to keep in the small universe, a "drift bottle" to be sent to the new universe.
Its main body is a microcomputer, and the quantum memory of the computer stores all the information of the computer host of the small universe. This is almost the entire memory of Trisolaris and the earth's civilization.
When a new universe is born, the metal box will receive the signal from the door, and then use its own small thruster to pass through the door and enter the new universe.
It will float in the high-dimensional space of the new universe, waiting for the day to be picked up and interpreted.
At the same time, it will also use neutrino beams to continuously play out the information it has stored, if there are neutrinos in the new universe.
Cheng Xin, who advocated doing this, seemed to feel that other small universes, those that responded to the call of the Return Movement, were also doing the same thing.
If a new universe is born, it will contain many bottles from the old universe.
It is believed that the information stored in a considerable part of the memories in the bottles may reach such an extent: it records all the memories and consciousness of every individual of that civilization, as well as all the biological details of each individual, so that the information in the new universe is A civilization can restore that civilization based on this information.
"Can I leave another five kilograms?"
At this time, Cheng Xin suddenly asked.
She's on the other side of the spacecraft, wearing a spacesuit and holding a glowing, transparent orb.
The sphere is about half a meter in diameter, with several water balls floating inside, some with small fish swimming inside, and some with green algae growing inside; there are also two floating miniature land masses with tender green grass growing on them.
The light is emitted from the top of the sphere, where a small luminous body is installed, which is the sun of this small world.
This is a fully enclosed ecological ball, the result of more than ten days of work by Cheng Xin and Zhizi. As long as the little sun inside the ball can still shine, this small ecosystem can survive.
As long as it remains here, Universe 647 will not be a dark world without life.
"It should be possible. The universe will not collapse just because of these five kilograms."
Before Tomoko could answer, Guan Yifan said uncertainly.
Of course, he had an unspoken idea; maybe the universe would really change from closed to open due to the difference in mass of one atom.
The ingenuity of nature sometimes exceeds imagination. For example, the birth of life requires the precise coordination of various cosmic parameters with an accuracy of one billionth of a billion.
But Cheng Xin could still keep her ecological ball, because among the countless small universes created by countless civilizations, there must be a considerable part that did not respond to the call of the Return Movement. Therefore, the mass of the large universe that was eventually taken away was at least several hundred million tons. Maybe even hundreds of billions of billions of tons.
If this idea is right, then we can only hope that the universe can ignore this error.
Otherwise, they cannot imagine the consequences...
Then, the fusion engine started, the thruster emitted a faint blue light, and the spacecraft slowly passed through the door to the universe.
Only the drift bottle and the ecological ball are left in the small universe. The drift bottle disappears into the darkness. In the one-thousand-meter-square universe, only the little sun in the ecological ball emits a little light.
