Chapter 491: Chapter 492 Light-Year Communication (Part I)
"Everyone, pay attention! Start slowing down!"
At the beginning of the interstellar 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 annihilation reaction and release a large 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 occupied by them.
"A monomer star system, the main sequence star is a yellow dwarf, but the mass is small, and there are five planets 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 calculated from the designed stellar 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 planet with a complex ecosystem.
Some collectors complained in the group because of the stimulation of the livable planet 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.
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-scale communication. Take the feedback information needed for sub-light speed navigation, which requires a whole planet-level energy supply to achieve the feedback signal that spans several light years.
Nowadays, such feedback signals are transferred from planets 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 planet'.
"How to achieve it? Is it enough to just get away from the planet'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 planet.
Hearing the collector's inquiry, the same clan did not restrain to inform the collector of their ideas.
"Yes, that's enough. Using the visible spectrum communication of stars is very simple and direct. Except for the disadvantage of light speed delay, there are basically no shortcomings. 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-distance communication 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 clan.
"No, I know that using stellar spectrum communication. It needs enough orbiting satellites to block the stellar light, and it is necessary to remove at least one whole planet."
The reason why the collectors say this is because they did it. The initial star broadcast information in this way, combining the polarized spacecraft of the Selin people and some polarized organisms added by Hogu later, 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 radio communication is realized.
However, the idea of the collector was quickly rejected by the same clan.
"No, no, no, you don't need to do that much."
