<h4>Chapter 491: Chapter 492 Light-Year Communication (Part I)</h4>


    "Everyone, pay attention! Start slowing down!"


    At the beginning of the interster voyage again, they went to the destination star. After receiving the feedback signal from the destination star, they opened the airtight valve in their body and sprayed hydrogen mass on the anti-matter shield in front of them to make it have an annihtion reaction and release arge number of gamma rays to slow down.


    Time and space change from distortion to normal state, and the star rainbow phenomenon disappears, and the stars return to the correct position.


    After arriving at the outermost Kuiper belt of the destination star, individuals of collectors impatiently turned on their biological radar to observe the star system that was about to be upied by them.


    "A monomer star system, the main sequence star is a yellow dwarf, but the mass is small, and there are fives inside. In addition to the Kuiper Belt, there are also two asteroid belts orbiting the star."


    "Confirmed, it''s the same as the remote observation."


    The individual who observed the collector broadcasts the information he observed to all members. Not only does it have such behavior, but there are also several collectors in the group who behave like this.


    This is to avoid observation errors. The farther the distance, the greater the observation error. Increasing the number of observers is an excellent way to reduce the error.


    So far, the distance has been calcted from the designed ster system with pressure giant as the starting point, and the collectors have crossed a total distance of more than 60 light years.


    "Well, it''s another ordinary star system. Why can''t we make some new discoveries? For example, the previously discovered habitable with aplex ecosystem.


    Some collectorsined in the group because of the stimtion of the livable in front of them, which aroused the enthusiasm of some collectors to find other civilized races.


    Finding a new civilization will be of great help to the ethnic group, and the ethnic group will usher in new changes - all the collectors are unanimously convinced that even newborn individuals, because the Selin civilization has made the whole ethnic group progress beyond imagination, so they will think so.


    Without the Selin civilization, it would be difficult for them to study mathematics and physics in depth. At most, they can onlye into contact with the shallowyer. The limit of the development and growth of the poption is limited to the two fields of chemistry and organic biology. It is impossible for the poption to study mother ship biology, antimatter giant structure, leap forward biology, protonttice... These, Although I have the ability to do it, I didn''t expect that such a concept would not exist from the beginning.


    Therefore, the discovery of a new civilization means the discovery of a new field of knowledge, which has be a subconscious idea of the collectors. Of course, the new field of knowledge also means a new round of technological explosion of the ethnic group.


    This is a great thing, and the collectors are of course very eager.


    "Don''t ask too much. That kind of is very rare. If it is everywhere, then we don''t need to keep that for ethnic research."


    "That''s right, but even if the standard is low, we have never met a with life. I thought that even if we can''t find a livable with aplex ecosystem for a while, it should be very simple to find some algae, fungi and single-celled organisms."


    During the voyage of more than 60 light years, the collectors have experienced two star systems, one is a three-star system and the other is a four-star system, which are very stable. The distance between them is more than 20 light-years. Except for one of the four-star systems to give the collectors a rtively novel observation experience, the others are simr.


    It is nothing more thans, stars, asteroids, interster dust and so on.


    "If life was everywhere, the current universe would not be as silent as it is now."


    "Huh? Dead silence..."


    He said unintentionally and listened to the message replied by his peers, which made the collector who was stillining think about it.


    "What''s the matter?"


    I haven''t received a reply for a long time. The same family ismunicating with this collector''s feedback back information, and the collector also took the opportunity to ask the same family for verification.


    "You just said that the universe is dead, right?"


    "That''s right. If it''s not dead, it''s easy for us to find new civilizations. As long as the technical level of these civilizations can reach the level ofary gravity, it is not difficult to achievemunication on the scale of several light years."


    He thought that the collector was thinking about the reason why he judged the cosmic environment as ''dead silence'' in his previous words, and exined the reason why he said so.


    The collector is very confused, because the standard given by the same race is too low. It is not so simple to carry out light-year-scalemunication. Take the feedback information needed for sub-light speed navigation, which requires a whole-level energy supply to achieve the feedback signal that spans several light years.


    Nowadays, such feedback signals are transferred froms to star orbits by stars, so that the feedback signal can travel for more than 20 light years without attenuation.


    Needless to say, the technical difficulty here is not as simple as the same family said, ''just need to be able to get out of the gravity of the''.


    "How to achieve it? Is it enough to just get away from the''s gravity? Are there no other conditions?"


    The collector felt strange. Although it knew that there was no reason for its peers to talk nonsense about it, it could not imagine what to do to exchange information across light years with a technical level away from the gravity of the.


    Hearing the collector''s inquiry, the same n did not restrain to inform the collector of their ideas.


    "Yes, that''s enough. Using the visible spectrummunication of stars is very simple and direct. Except for the disadvantage of light speed dy, there are basically no shorings. Even the observer is saved. With the naked eye of the Selin people, you can get information spanning light years."


    The transmission of Morse code through the change of star brightness can also realize ultra-long-long-distancemunication across light years. This technology is not difficult, and the difficulty is mainly how to block the star''s light to make the star''s brightness change significantly.


    But the collector thought about it carefully and felt that something was wrong, and then he refuted the same n.


    "No, I know that using ster spectrummunication. It needs enough orbiting satellites to block the ster light, and it is necessary to remove at least one whole."


    The reason why the collectors say this is because they did it. The initial star broadcast information in this way,bining the prized spacecraft of the Selin people and some prized organisms added by Hoguter, so as to realize the construction of Dyson Cloud.


    Relying on this Dyson cloud, the brightness of the star changes, and the light-year-level radiomunication is realized.


    However, the idea of the collector was quickly rejected by the same n.


    "No, no, no, you don''t need to do that much."
