"Do you know the circular space station when the Celine just boarded the universe?"

Hearing this mention of the same tribe, the collectors searched for memories, and quickly recalled this from their memories. When the Serines were still in the era of great powers, and when there were many countries, various countries scrambled to explore the universe, and then slowly evolved into a common one. Raise funds to build a large space station.

This space station has a ring structure, just like a tire. It has many technical immaturities because it is still in the early stages of space technology development.

However, there is one thing that can be drawn, and that is the ecological self-sustaining system inside the space station. As long as there is sunlight, the space station is another small Serine.

It's just that the maintenance of such a large space station is a difficult problem that cannot be solved. This is like constantly repairing a ship in the ocean, which is very troublesome.

At the same time, this kind of space station could not produce resources, so it was left aside by the empire and applied the useful technologies of the ecological self-sustaining system to ships.

"I know this. It's the space station that uses centrifugal force to replace gravity. What did you mention this for?"

"When this ring-shaped space station is erected, it is a wheel with a large area, and a large number of flipped light barriers are laid. A wheeled space station like this has produced 10,000 seats, and the orbits are designed so that they are arranged in a two-dimensional square array. , It can affect the brightness of the star's outer dispersion."

The same clan explained the method and steps of the cross-light-year communication that he mentioned earlier.

According to the description of his own family, the collector began to calculate the feasibility of it. Soon, it rejected the statement of the same family.

"Not enough, in front of the stars, even if there are 10,000 such circular space stations, they are nothing but dust."

The stars are very large and outrageous. So far, collectors have dismantled all the planets to build antimatter giants. None of the stars of the star system are completely obscured, even the smallest red dwarfs.

The same clan does not deny the small coverage area, but it has other plans to make up for this shortcoming.

"It is indeed dust, but a leaf is obscured. Although the area of ​​the leaf is small, it can cover a large mountain. These ring-shaped space stations do not necessarily need to be located very close to the star. Although they are arranged in a square array, the distance can be extended. It’s very open, which will also cause the star’s luminosity to drop."

After thinking about it, my fellow clan felt that the examples were insufficient, so I added one more sentence.

"Some time ago, didn't a pioneering ethnic group broadcast a suspected stellar building?"

"That's a false alarm. The Kuiper belt of the star system has a dense amount of meteorites. These meteorites obscure the stars and make the stars bright and dark when they revolve... You mean to use this principle?"

Just like a solar eclipse and a lunar eclipse, as long as the distance is sufficient, a grain of sand can achieve the effect of shielding the light source. The most indispensable thing in this vast universe is the large-scale spatial distance.

Although the collector is not smart, it is not stupid. It quickly understood the meaning of its own clan, and the same clan continued to explain it.

"Yes, the technical requirements are not high, and the space ecological self-circulation and orbital elevators only need these two conditions to achieve the transmission of information across light years."

"But this kind of star obscuration is still not obvious. It requires sufficient precision observation to read the information in the brightness change of the star... Well, you are right. Without discussing the information reception, this is indeed a light-year span. The level of information transmission method is not high in technical content and consumes not much energy."

At the end of the discourse, it must be admitted that the light-year-level communication method described by the same family is really very feasible, and the energy required for communication is not high. It just rotates the reflector laid on the large space station. That's it, how much energy does it take to rotate some reflectors, not to mention that there is a natural energy source like stars. If energy is needed, it can be directly connected to the solar panel?

"By the way, what did you just want to say?"

The same clan then remembered that the collector seemed to have something to say just now. The two continued the topic just now, and the collector answered.

"I want to say that our current observations of the universe do not match the theory. It shouldn't be so quiet."

"Theory? What theory?"

The same clan is puzzled, it does not understand what the theory put forward by the collector is.

The collector explained.

"The age of the river system we live in is estimated to be between 13.5 billion and 13.8 billion years. Such a long time span will naturally breed civilization, and civilization will continue to develop and expand. , Which is what we are doing now."

"And this derives a demand, that is, cross-light-year communication. High-tech civilization can be ignored, but as long as there is no technologically developed super-light-speed civilization, it must use light-speed communication, and light-speed communication has diminishing The greater the demand for distant energy, the greater the possibility that stars, a natural energy source, will be used as a means of communication."

"Considering the delay of the speed of light, even if these civilizations that did not exceed the speed of light suddenly disappear collectively someday, the information of their civilization will remain for a period of time before they disappear, at least for seven to eighty thousand years."

The collector's estimate is not unfounded, it is a prediction time given in consideration of the radius of an entire river system.

"Too many. Seven or eighty thousand years of light-year communication. It needs to cover the entire star. The information can be learned with the barren vision of the Serines. It can do this kind of thing, that civilization. The technical level is at least the same as that of the ethnic group, capable of dismantling planets and building individual wrapped stars..."

Gradually falling into contemplation in the information error correction, the question raised by the collector slowly attracted the thinking of the same family, and the same family began to speculate.

"Wrapping the entire star, if this method is used for information exchange that spans tens of thousands of light years, it is not very resource intensive..."

"Well, this is indeed a problem."

People are pushed by oneself, the goal of the ethnic group is the entire river system, so other civilizations must think the same way, at least the Serines are correct, and if the speed of light has been unable to break through, then the ethnic group will establish such a light-year communication in each star. That is something that will inevitably happen.

Therefore, civilizations that predated the expansion of Amoeba's influence in the universe must have thought of this. The most important thing is that this kind of communication method is very cheap, so there is no reason not to build it.

"Then what is the answer to your question?"

The clan who didn't understand it asked the collector, it wanted to know the answer.

However, the collector of this question has no answer himself, only guessing.

"Since reality is so illogical, there should be some reason that has caused the ‘dead’ cosmic environment like this."

"There are many speculations about this reason. For example, the entire river system has no other civilization besides us and the Serines."

"How is this possible, a whole river system is so big..."

The same family directly refuted the collectors without even thinking about it. In terms of probability, the river system with hundreds of millions of stars has only two civilizations, and these two civilizations happened to be born in the same star system. This probability is too small. Up.

"Don't rush to the conclusion, listen to me." The collector said.

"You also know that during this period of exploration activities, the biggest result is to find a livable planet with a complex ecological circle. At the same time, according to the book of formations left by the Hui civilization, it is stated that some things have happened in this river system. , So this inference is tenable."

The collector explained the reason for this speculation. If it was before, when the starting star had not been stepped out, the collector also believed that the existence of civilization is very common, and there may be a civilization at least fifty to sixty light-years away. Kind of degree.

However, the reality is completely contrary to what they had guessed. They are in the same star system as the Serines. It is really a very, very small probability, and then it happened.

It's like asking a person who won the lottery, asking him why he won the lottery-who knows this question? It's whoever's turn.

After this reason was recognized by the same clan, the same clan then became curious about other speculations~lightnovelpub.net~ It wanted to know what else the collectors could deduce based on the universe’s “dead silence”. ask.

"What about the other guesses?"

The collector paused for a while, and responded to the questions of his family.

"For another example, some unknown external force erased these civilizations without a trace."

"..."

There is a long silence on the side of the same race. To be honest, this answer is quite terrifying. It is definitely not the ability of the race to contend that it can achieve this level of external force.

At least it is clear that even if it triggers a supernova explosion and further collapses the neutron star into a black hole, it is absolutely impossible to wipe out the many civilizations of the entire river system without a trace.

This kind of power is extremely terrifying, just thinking about it is enough to make your back chill.

The most frightening thing is that this possibility seems to be very large. In a time span of tens of billions of years, the river system is absolutely capable of nurturing civilizations, and these civilizations will inevitably develop in the natural law of survival of the fittest, and eventually become the hegemon of the river system. Level civilization.

Will a civilization like this allow other nascent civilizations to surpass itself and be deprived of dominance? Obviously impossible.

With the passage of time, the technological level of the overlord civilization will steadily improve, and the overlord civilization that rules the river system will only get stronger and stronger, and its control over the river system will continue to be strengthened.

Under such circumstances, it is not impossible for the overlord level civilization to erase the erased civilization with an incomprehensible and unimaginable attack method.

"Don't be nervous, this possibility is not high. If such an unknown external force really exists, then we should not be able to run so far now. We are hundreds of light years away from the starting star."

The gatherer has guessed what the same race is thinking, and it does not think this possibility is high enough.
