"Do you know the ring space station when the Cerlem people just boarded the universe?"

When I heard that the same family was mentioned, the collector turned to the memory, and soon recalled this from memory. In the period when the Serle people were still in the era of great powers, during the period of the states of the country, countries rushed to explore the universe.

Graduation and construction of large space stations.

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

However, there is a hand that can be taken, that is, the ecological self -maintenance system inside the space station. As long as there is sunlight, this space station is another small Selin.

It's just that such a large space station is a difficult problem in maintenance. This is like keeping a boat in the ocean, which is very troublesome.

At the same time, this kind of space station does not produce resources, so it is left aside by the empire to apply the useful technologies such as ecological self -maintenance systems to the ship.

"I know this is the space station that uses centrifugal forces to replace gravity. What do you mention this?"

"Erection this ring space station is a large area of ​​wheels. A large number of shields that can be flipped can be laid. Ten thousand stations like such wheels.

, Can affect the brightness of the stars. "

The same family explains the steps of the cross -light annual communication that he mentioned earlier.

The collector began to calculate how much the feasibility was based on his description. Soon, it rejected this statement of the same family.

"Not enough, in front of the star, even if there are 10,000 stations at the ring space station, it is just dust."

The stars are very large and outrageous. So far, the collectors have demolished all planets to build an anti -material giant. There is no star system.

For the small shielding area, the same family does not deny it, but it has other solutions to make up for this shortcoming.

"It is indeed dusty, but a leaf is obstructive. Although the area of ​​the leaves is small, it can cover a mountain. These ring space stations may not necessarily need to be very close to the stars. Although each other is arranged into a square array, the distance can be pulled.

It is very open, this will also lead to the decline in the light of the star. "

After thinking about it, the same family feels that there are insufficient examples, and add another sentence.

"Some time ago, isn't there a pioneering ethnic broadcast found a suspected star building?"

"That's a mistake. The amount of meteorites of the star system Koyber is very dense. These meteorites cover the stars. During the revolution, the star brightness is bright and dark ... Do you mean using this principle?"

It is almost the same as a day of eclipse. As long as the distance is sufficient, a grain of sand can achieve the effect of covering the light source. The most missing thing in this vast universe is the large -scale space distance.

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

"Yes, the technical level of the technical level is not high, the space ecological self -cycle, the rail elevator, only these two conditions can achieve the transmission of information on the light year."

"But such a star cover is still not obvious. Observations that require sufficient accuracy to read the information in the brightness of the star ... Well, you are right, if you do n’t discuss information receiving, this is indeed a cross -light year

Level information transmission method, the technical content is not high, and the energy consumption is not much. "

At the end of the discourse, it has to be admitted to collecting this. This light -level communication method said by the same family is really feasible, and the energy required for communication is not high.

Just, how much energy can I need to rotate some reflective boards, not to mention the natural energy source of the star. If you need energy, you can directly connect the solar panel?

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

The same family 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, the results of our observation of the universe are not theoretically inconsistent, it should not be so quiet."

"Theory? What theory?"

The same family is puzzled, and it does not understand what the theory proposed by the collector.

The collector explains.

"This river system that we are in speculation is between 13.5 billion and 13.8 billion years. Such a long time span will naturally bred civilization, and civilization will continue to develop and expand.

That is what we are doing now. "

"In this way, a demand is derived, that is, cross -light annual communication, and high -technology civilization can be ignored, but as long as there is no technical development of a high -speed civilization, it must use light speed communication.

The greater the demand for energy, the natural energy source of the star is also very likely to be used as a communication method. ""

"Considering the delays of light, even if these civilizations without ultra -light speed disappear, the information of their civilization will remain for a while to disappear, at least 780,000 years."

The valuation of the collector is not basically not foundation. This is the prediction time given by the radius of the entire river system.

"Too much, the cross -light annual communication of 70,000 to 80,000 years, then you need to cover the entire star, and you can learn the level of information with the barren vision of the Serle people.

The technical level is at least similar to the ethnic group. It can disassemble the planet and build an individual package stars ... "

In the information correction, the problem gradually attracted the thoughts raised by the collector, which slowly attracted the thinking of the same family. The same family began to speculate.

"Package the entire star, if this method is used for information exchanges for tens of thousands of light years, it is not much resources ..."

"Well, this is indeed a problem."

The goal of the ethnic group is the entire river system. Then other civilizations must think so. At least the Serle people are right, and if the speed of light cannot be broken, then the ethnic group has established such a cross -light year communication in various stars.

That is, what will happen.

Therefore, the civilization that expands forces to the universe earlier, it is bound to think of this stubble. The most important thing is that such a communication method is cheap, so there is no reason not to create it.

"So what is your answer?"

If you do n’t understand, the same family inquires the collector, it wants to know the answer.

However, the collector of this question has no answer itself, only speculation.

"Since the reality is not logical, it should have some reason, which has caused the cosmic environment of this 'dead silence' now."

"There are many speculations about this reason, such as the entire river system, there is no other civilization except us and the Thrin people."

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

If you don't think about the same family, you will directly refute the collector. In terms of probability, there are only two civilizations with a river system with hundreds of millions of stars, and these two civilizations are born in the same star system. This probability is too small.

It's.

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

"You also know the exploration activities during this period of time. The biggest results are just to find a livable planet with a complex ecosystem. At the same time, according to the Book of Formation left by the Hui civilization, some things have happened in this river system.

Therefore, this inference is to stand up. "

The collector explained that he raised this speculation. If it was before, when the starting star had not been set out, the collector also believed that the existence of civilization was very common, at least separated by fifty or sixty years.

Excise.

However, the reality is completely opposite to what they guess. They are in the same star system as the Thrin people. It is really a very small probability, and then it happens.

It's like asking a lottery ticket, and asking why he will win the lottery -who knows this question? Who is the turn?

After this reason was recognized by the same family, the same family was curious about other guessing. It wanted to know that the collector can derive something according to the "dead silence" of the universe, so it asked.

"What about other guess?"

The collector paused and responded to the questions of the same family.

"Another example, some kind of unknown external force wiped out these civilizations."

"..."

There is a long -term silence in the same family. To be honest, this answer is quite scary. It is definitely not the ability of ethnic groups to be able to compete.

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

This power is extremely scary. Just thinking about it is enough to make people cold.

The most terrible thing is that this possibility seems to be very large. Time span of tens of billions of years. The river system is absolutely capable of breeding civilization. These civilizations will inevitably develop in the natural laws of survival of the fittest, and eventually become the hegemon of the river system.

Class civilization.

Civilization like this allows other new civilizations to overtake themselves and have been taken away from the dominant status? Obviously impossible.

Over time, the technical level of overlord -level civilization will be steadily improved. The hegemony -level civilization that rule the river system will only become stronger and stronger, and the control of the river system will continue to strengthen.

Under such circumstances, the hegemonic civilization uses an attacking method that is difficult to understand and beyond imagination to erase the wiping civilization. This is not impossible.

"Don't be nervous. This is not possible. If this unknown external force really exists, then we should not be able to run out so far. We have a distance of hundreds of light years."

The collector has guessed what the same family is thinking, it does not think that this possibility is high enough.

Hearing the reason for the collector, the same family also had a little peace of mind.

"To be honest, you successfully scared me."

"whee……"

"I'm not boasting you."
