Chapter 492: Chapter 493 Light-Year Newsletter (Part 2)
"Do you know the circular space station when the Selene just landed in the universe?"
Hearing this mention of the same clan, the collectors searched for memories and quickly recalled this from their memory. In the era when the Selin people were still in the era of great powers and countries were full of countries, countries scrambled to explore the universe, and then slowly evolved into a joint fund-raising to build a large space station.
This space station is a ring structure, just like a tire. It has many technological immaturity, because it is still in the early stage of the development of space technology.
However, there is one thing that can be taken out, that is, the ecological self-sustaining system inside the space station. As long as there is sunlight, the space station is another small Selin.
It's just that such a large space station is a problem that can't be solved in maintenance, which is like constantly repairing a ship in the ocean, which is very troublesome.
At the same time, this kind of space station cannot produce resources, so it is left aside by the empire and applies useful technologies such as ecological self-maintenance systems to ships.
"I know this. It's the space station that uses centrifugal force to replace gravity. Why do you mention this?"
"To erect this ring space station, that is, a large number of wheels, laying a large number of reversible light shields, such a wheel space station creates 10,000, and the orbit is designed to arrange them into a two-dimensional square array, which can affect the brightness of the star's dispersion."
The same family explains the methods and steps of cross-lightyear communication mentioned earlier.
According to the description of his own race, the collector began to calculate how feasible it was. Soon, it rejected the claim of the same race.
"Not enough. Even if there are 10,000 ringed space stations in front of the star, it is just dust."
The stars are very large and ridiculously large. So far, collectors have dismantled all the planets to build antimatter giants. No star in the star system is completely obscured, even the smallest red dwarf.
The same clan does not deny that the shielding area is small, but it has other solutions to make up for this deficiency.
"It is indeed dust, but although the area of the leaves is small, it can cover a big mountain. These ring space stations do not need to be very close to the stars. Although they are arranged in phalanxes, the distance can be pulled very far, which will also lead to the decrease in the brightness of the stars."
After thinking about it, the same family felt that the example was insufficient, and added another sentence.
"A while ago, wasn't there a pioneering group broadcast that found a suspected stellar building?"
"That's a false alarm. The meteorites in the Kuiper belt of the star system are very dense. These meteorites cover the star and make the star's brightness flickering when it is in orbit... Do you mean to use this principle?"
It is almost the same as a solar eclipse and lunar eclipse. As long as the distance is enough, 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 space distance.
Although the collector is not smart, he is not stupid. He quickly understands the meaning of his own clan, and his clan continues to explain himself.
"Yes, the technical level requirements here are not high. Space ecological self-circulation and rail elevators only need these two conditions to achieve information transmission across light years."
"But such stellar occlusion is still not obvious. It requires accurate observation to read the information in the brightness change of the star... Well, you're right. Without discussing information reception, this is indeed a method of information transmission at the light-year level. The technical content is not high and does not consume much energy."
In the end, the collection has to admit that the light-year-level communication method mentioned by the same family is really very feasible, and the energy required for communication is not high. It is just to rotate the reflector laid on a large space station. How much energy is needed to rotate some reflector, not to mention stars. Natural energy source, if you need energy, can't you just connect the solar panel directly?
"By the way, what did you just want to say?"
Only then did the same clan remember that the collector seemed to have something to say just now.
The two continued the topic just now, and the collector replied."I want to say that the results of our observation of the universe now are not theoretically consistent. It should not be so quiet."
"Theory? What theory?"
The same family is puzzled that it does not understand what the theory put forward by the collector is.
The collector explained.
"The river system we are in is estimated to be between 13.4 billion and 13.4 billion years old. Such a long time span will naturally give birth to civilization, and civilization will continue to develop and expand, which is what we are doing now."
"And in this way, a demand is derived, that is, cross-lightyear communication. High-tech civilization can be ignored, but as long as the technology does not develop a civilization with super-light speed, it must adopt light-speed communication, and the speed of light communication is decreasing. The farther the distance, the greater the energy demand, the natural energy source of the star, is likely to be greatly benefit. Use it as a means of communication.
"Considering the delay of the speed of light, even if these civilizations without superluminal speed suddenly disappear collectively one day, the information of their civilization will be retained for a period of time before disappearing, at least 70,000 to 80,000 years."
The collector's valuation is not unfounded, it is the prediction time given taking into account the radius of an entire river system.
"It's too much. Seven or 80,000 years of light-year-crossing communication needs to cover the whole star to the extent that information can be obtained with the barren vision of the Selin people. This kind of thing can be done. The technical level of that civilization is at least similar to that of the ethnic group, which can dismantle the planets and build individuals to wrap stars..."
Gradually lost in contemplation in the process of information correction, the question raised by the collector slowly attracted the thinking of the same race, and the same race began to speculate.
"If this way of wrapping the whole star is used for information exchange spanning tens of thousands of light years, it is not very resource-consuming..."
"Well, this is really a problem."
Pushing people by themselves, the target of the ethnic group is the whole river system, and other civilizations must also think so. At least the Selin people are right, and if the speed of light cannot be broken through, then it is inevitable that the ethnic group establishes such a light-year communication in various stars.
Therefore, the civilization that expanded its power to the universe earlier than the Amoeba must also think of this. The most important thing is that such a communication method is very cheap, so there is no reason not to create it.
"So what's the answer to your question?"
The same race, who can't figure it out, asks the collector, and he wants to know the answer.
However, the collectors of this question do not have the answer themselves, only guess.
"Since the reality is so illogical, there should be some reason for the 'dead' cosmic environment."
"There are many speculations about this reason. For example, there is no other civilization in the whole river system except us and the Selin people."
"How can this be? The whole river system is so big..."
The same clan directly refuted the collector without thinking about it. In terms of probability, there are only two civilizations in the river system with hundreds of millions of stars, and the probability that these two civilizations are born in the same star system is too small.
"Don't rush to draw a conclusion. Listen to me." The collector said.
"You also know the exploration activities during this period. The biggest achievement is only to find a livable planet with a complex ecosystem. At the same time, according to the book left by the Hui civilization, something has happened in this river system, so this inference is tenable."
The collector explained his reason for making this speculation. If it had not been before, before stepping out of the starting star, the collector also thought that the existence of civilization was very common, and at least there would be a civilization after 50 or 60 light years.
However, the reality is completely contrary to what they guess. They are in the same star system as the Selin people, which is really a very, very small probability, and then it happens.
It's like asking a person who won the lottery and why he won the lottery - who knows this question? It's who it's who it is.
After this reason was recognized by the same clan, the same clan then became curious about its other speculations. wanted to know what the collector could deduce from the 'dead silence' of the universe, so it asked.
"What about other guesses?"
The collector paused and replied to the questions of the same race.
"For another example, some unknown external force erases these civilizations without a trace."
"..."
There is a long-term silence on the side of the same race. To be honest, this answer is quite horrible. It is definitely not the ability of the ethnic group to compete with this level of external force.
At least it knows that even if it causes a supernova explosion and further condenses the neutron star into a black hole, it is absolutely impossible to erase many civilizations in the whole river system without trace.
This kind of great power is extremely horrible. Just thinking about it is enough to make people feel cold.
The most terrible thing is that this possibility seems to be very high. Over a period of 10 billion 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-level civilization of the river system.
Will civilizations like this allow other new civilizations to catch up with themselves and be deprived of their hegemony? Obviously impossible.
With the passage of time, the technical level of the hegemonic civilization will steadily improve, the hegemonic civilization that rules the river system will only become stronger and stronger, and the control of the river system will continue to be strengthened.
Under such circumstances, it is impossible for hegemonic civilization to erase the civilization that should be erased by an incomprehensible and unimaginable attack.
"Don't be nervous. This possibility is not high. If such an unknown external force really exists, we should not be able to run so far now. We are hundreds of light years away from the starting star."
The collector has guessed what his peers are thinking, and it doesn't think it's possible enough.
