"You know the circular space station when the Serens first landed in space, right?" Hearing this from their fellow clansmen, the gatherers rummaged through their memories and quickly remembered that in the era when the Serens were still a great power and there were many countries, countries competed to explore the universe, and then slowly evolved into a joint fund-raising to build a large space station.

The space station is a ring-shaped structure, like a tire, and it has many technical imperfections, because it is still in the early stages of the development of space technology.

However, there is one thing that can be handled, and that is the ecological self-sustaining system inside the space station, as long as there is sunlight, then this space station is another type of Selene.

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

At the same time, the space station does not produce resources, so it has been left behind by the Empire to apply useful technologies such as ecological self-sustainment systems to ships.

"I know this, it's the space station that uses centrifugal force to replace gravity, what are you doing with this?"

"Erect this annular space station, that is, a large area of wheels, a large number of light barriers that can be flipped, like this wheel space station to create 10,000, design the orbit so that they are arranged into a two-dimensional square, can affect the brightness of the star scattering." The same clan is aware of the method and steps of cross-light year communication that they mentioned earlier.

Based on the descriptions of their own kind, the gatherer began to gauge how feasible it was, and soon rejected the method of his kind.

"It's not enough, in front of the stars, even if there are 10,000 of them, that kind of annular space station is just dust." Stars are so big, so big that the collectors have so far torn down all the planets to build antimatter megastructures, and not a single star in the star system has been completely obscured, not even the most massive red dwarfs.

The same family does not deny the area of shading, but it has other options to make up for this shortcoming.

"It's really dust, but a leaf obscure, although the area of the leaf is enough to cover a mountain, these ring space stations don't necessarily need to be very close to the star, although they are arranged in a square between each other, but the distance can be stretched wide, which will also cause the luminosity of the star to decrease." After thinking about it, the same clan felt that the examples were insufficient, and added another sentence.

"Some time ago, wasn't there a pioneer race that broadcast a suspected stellar building?"

"That's a false alarm, the star system has a lot of meteorites in the Kuiper Belt, and these meteorites obscure the star, and the brightness of the star flickers and dims as it orbits...... Are you using 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 obscuring the light source, and the most indispensable thing in this vast universe is large-scale spatial distance.

The gatherer, though not smart, is not stupid either, and he quickly understands what his kindred meant, and his kindred continues to be clear.

"That's right, the technical level requirements here are not high, and only these two conditions are needed to achieve cross-light year information transmission."

"But this stellar occlusion is still not obvious, and it requires accurate observation to read the information in the brightness of the star...... Well, you're right, without talking about information reception, this is indeed a light-year way of transmitting information, which is not very technical and does not consume much energy. At the end of the words, I have to admit that this light-year communication method of the same family is really very feasible, and the energy required for communication is not high, just turn the reflector laid on the large space station, how much energy can be needed to rotate some reflectors, not to mention that there is a star as a natural energy source, if you need energy, you can directly connect the solar panels?

"By the way, what did you just think?" Only then did the clan remember that the gatherer seemed to have something to say just now, and the two continued the topic just now, and the gatherer replied.

"I think that the results of our current observation of the universe do not correspond to theory, and it should not be so quiet."

"Theory? What theory? The clan was puzzled, it didn't understand what the theories of the gatherers were.

The gatherer explained.

"The estimated age of the river system we are in is about 13.5 billion to 13.8 billion years, and 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 this gives rise to a demand, that is, cross-light year communication, high-tech civilization can be ignored, but as long as the technology has not developed a faster-than-light civilization, it must use light-speed communication, and light-speed communication is decreasing, the farther the distance, the greater the energy demand, and the star is a natural energy source is very likely to be used as a means of communication."

"Considering the delay of the speed of light, even if these civilizations that do not have the speed of light suddenly disappear collectively, the information of their civilization will remain for a period of time before disappearing, at least seventy or eighty thousand years." The collector's estimate is not unfounded, it is a prediction given taking into account the radius of an entire river system.

"It's too much, seventy or eighty thousand years of light-year communication, that needs to be able to obscure the entire star, to the extent that the information can be obtained with the barren vision of the Serenes, to be able to do this kind of thing, the technological level of that civilization is at least about the same as that of the race, and it can disassemble the planets and build individual wrapping stars......" gradually fell into contemplation in the information correction, and the question raised by the collector slowly attracted the thinking of the same race, and the same race began to speculate.

"Wrapping the entire star in such a way is not very resource-intensive if it is used for the exchange of information across tens of thousands of light-years......"

"Well, that's a real problem." If you push yourself, the goal of the race is the entire river system, then other civilizations must think the same, at least the Serens are right, and if the speed of light has not been able to break through, then it is inevitable that the race will establish such cross-light year communication in various stars.

Therefore, civilizations that expanded their power to the universe earlier than amoeba will inevitably think of this stubble, and the most important thing is that such a communication method is very cheap, so there is no reason not to make it.

"So what's the answer to your question?" The puzzled kindred asks the gatherer, and it wants to know the answer.

However, the collectors themselves have no answer to this question, only speculation.

"Since reality is so illogical, there should be some reason for the current 'dead silence' cosmic environment."

"There is a lot of speculation about the reason for this, such as the fact that there is no civilization in the entire river system except for us and the Serenes."

"How is this possible, a whole river system is so big......" The same clan directly refuted the collector without thinking about it, and in terms of probability, there are only two civilizations in the river system with hundreds of millions of stars, and these two civilizations happen to be born in the same star system, which is too probable.

"Don't jump to conclusions, I'll finish listening." The Gatherer said.

"You also know that the greatest result of this period of exploration is only to find a habitable planet with a complex ecosystem, and at the same time, according to the Book of Arrays left by the Hui civilization, some things have happened in this river system, so this inference is tenable." The collectors understood the reason for their own speculation, and if it was before, before the beginning of the star, the collectors also believed that the existence of civilization was very common, at least fifty or sixty light years away, there might be a civilization to the same extent.

However, the reality is exactly the opposite of what they suspected, they are in the same star system as the Serenes, it is very, very probable, and it happened.

It's like asking a lottery winner why he won the lottery – who knows?

Whoever is the turn is whomever it is. After this reason was accepted by its kindred, the kindred then became curious about other speculations, and it wanted to know what else the gatherers could deduce from the fact that the universe was 'dead', so it asked.

"What about the other speculations?" The gatherer paused, replying to his kind's question.

"Another example is that some unknown external force has erased these civilizations without a trace."

"......" There was a long silence on the side of the same clan, to be honest, this answer is quite terrifying, and it is definitely not the clan that has the ability to resist this level of external force.

At least it knows that even if it triggers a supernova explosion and further collapses neutron stars into black holes, it is absolutely impossible to wipe out the entire river system without a trace.

This power is terrifying, and the mere thought of it is enough to send chills down the spine. The most terrifying thing is that this possibility seems to be very large, with a time span of 10 billion years, the river system is absolutely capable of giving birth to 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 a civilization like this allow other nascent civilizations to overtake themselves and be robbed of their supremacy? Apparently impossible.

And with the passage of time, the technological level of the overlord-level civilization will steadily improve, and the overlord-level civilization that rules the river system will only become stronger and stronger, and the control of the river system will also continue to strengthen.

Under such circumstances, it is not impossible for a hegemon-level civilization to wipe out the civilization that should be erased with an incomprehensible and unimaginable means of attack.

"Don't be nervous, this is not very likely, 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 had guessed what his fellow was thinking, and it didn't think it was likely high enough.

Hearing the reason of the gatherer, the same clan also had a little peace of mind.

"Honestly, you managed to scare me."

"Hee-hee-hee......"

"I'm not complimenting you." As they chatter, sub-lightspeed creatures have finally arrived in the Kuiper Belt, a new star system waiting to be developed.
