It is obviously not for humans. Ogun's history is too long. When Australopithecus appeared, it was already on the road. It was obviously born earlier than humans. Unless its builders mastered something beyond the law of cause and effect.
technology, otherwise, this thing cannot be for human beings.
But every part of Ogoneri indicates that its builder's technical level is on par with Earth's, let alone such a technical level.
But it is obviously not for disseminating information about its own planet. The symbol system in the core of Ogun is not for the convenience of alien interpretation. It simply combines the considerations of noise immunity and information density.
The Pioneer 10 and Pioneer 11 space probes launched by humans in the 1990s were equipped with the famous "Pioneer gold-plated aluminum plate". In the upper left corner of the plate, an image of a spin transition within a hydrogen atom was engraved.
, because hydrogen is a substance that widely exists in the universe. There is a short straight line under this symbol to represent "1" in binary. In this kind of hydrogen atom, the electron can change from spin up to spin down.
Designates a length (its wavelength is equal to 21 centimeters) and a length of time (the frequency is 1420 MHz). These two derived units are used to calculate the meaning of other symbols on the board. One of the 14 lines has a column with
The numbers written in binary form represent the pulse signal periods of the 14 pulsars (neutron stars) in the Milky Way. Since the signal period of each pulsar changes with time, aliens can calculate based on the pulse period at that time.
The launch time of this spacecraft. The length of the lines represents the distance of those pulsars relative to the sun. The mark at the end of each line represents its Z coordinate on the galactic plane.
In addition, there are images of a human male and a human female on it.
This set of information was later put into the Voyager and used as the cover of the Voyager golden record.
Although the amount of information is very small, it can at least be shown to aliens and most aliens can interpret it.
The symbols in Ogunne are beyond human interpretation.
David said without hesitation: "Build a large spaceship first."
"Uh-huh." Xiang Shan nodded: "Then what?"
Yawgmoth raised his hand and asked, "Anything else?"
"There are many questions. This is a large and systematic project, my friend. It is not just a scientific issue." Xiang Shan shook his neck: "For example, can a spaceship like Ogun be used for immigration?"
David shook his head: "Obviously impossible. Its intensity is too low, it cannot withstand acceleration and deceleration, and there is a risk of being torn apart by gravity even if it is slightly larger than a massive celestial body - tsk tsk, think about it, it has not been torn apart by Jupiter and Saturn.
Broken, it is quite lucky. Oh yes, it will take a century just to fly out of the solar system."
"Then make the spaceship smaller..." Yawgmoth said. If you can't build a spaceship with enough shear resistance to maintain a huge posture, then make it smaller. But he quickly shook his head and rejected it himself:
"It seems like it can't be too small. But it shouldn't be as big as Ogun."
Any species has minimum requirements for the size of its own "gene pool" - or the richness of its own species' genes. Adam and Eve are biological nonsense. It only takes one generation for the descendants of Adam and Eve to
Faced with the problem of inbreeding. The inbreeding coefficient between first-degree relatives is 1/4. In other words, each pair of alleles in the individuals they conceived has a 25% probability of coming from the same common ancestor of both parents. This will
This increases the risk of autosomal recessive diseases in their offspring, and it will not take long for them to collapse.
As for the specific number of people needed, humans themselves have not studied it thoroughly. Some people think that it may require several hundred people. Others think that at least one hundred and sixty people are needed. Of course, some scholars go to the extreme and think that the minimum number of people is only
It takes 98 people - a healthy group of 98 people is enough to rebuild human civilization.
In fact, genetic research also supports this theory. Some scholars believe that the combined gene richness of the entire human race is no more than that of a family of chimpanzees. It seems extremely distant to a human, but its evolutionary perspective is extremely close to the past.
Humanity once encountered natural disasters, and there were only a few hundred true Homo sapiens left. Then these "fire seeds" of modern humans, relying on the extremely excellent configuration of Homo sapiens, multiplied to every corner of the earth.
Xiang Shan sighed: "On the contrary, Yog. This is not just a biological problem. People die unexpectedly. If you bring the number of people to the limit, then if just one person dies in this group, the gene pool of the immigrant group will be reduced."
A valuable piece of the puzzle is lost.”
David nodded: "Space is no safer than the earth. Oh yes, the human body is adapted to the earth's gravity. Without centrifugal force to simulate gravity, human reproduction and growth will be affected."
"Secondly, there is the issue of fertility wishes. If accidental death is not considered, then each couple must have two children, and then these two children must grow up safely, and then each child must have two children with his partner after getting married.
For children, this can keep the population unchanged. But how can there be such a safe thing? Accidental death is always inevitable. Besides, not everyone wants to breed multiple offspring now."
"Even in an extreme case, if there is a poor guy who has bad luck with the opposite sex, then mankind will suffer great misfortune - another piece of the puzzle will be permanently lost in the gene pool of the immigrant group."
"In addition, there are also problems such as emotional discord after couples get married - unless there are regulations, free love is prohibited, and everyone waits for the system to assign a spouse. But that is too inhumane and prone to short-sightedness.
Self-manual screening. So you have to prepare ten times or a hundred times the minimum number of people."
"And in order to ensure that this immigrant group does not suffer from mental problems on the ship and spend all day thinking about how to kill their companions to relieve their boredom, a certain amount of space must be prepared for them."
"What about hibernation?" Yawgmoth asked.
David said: "Even the tardigrade, which is best at cryptozoology, cannot guarantee that it will be able to come back to life 100% after suspended animation. Judging from the current level of technology, human hibernation technology is nonsense, and hundreds of people may be frozen.
Even one of them may not be able to recover.”
"Freeze sperm and eggs? In this case, only one of the millions of sperm will survive." Yawgmoth said: "Hibernate a group of teachers... No, let AI raise them up? In this way, the spacecraft can be smaller
That’s a lot.”
David spread his hands: "Artificial wombs are a technical problem. And will children educated by AI have any recognition of human society? They can already be regarded as another civilization."
David sighed: "After all, why should we design an immigration fleet based on the current technological level of mankind? This is impossible."
"How do I know?" Xiang Shan sighed: "Suppose, join in, NASA finds signs that the sun is turning into a red giant, it may be tomorrow, or it may be five hundred years later, this process will be very sudden, and humans may at any time
Losing their hometown. While humans are studying group evacuation plans, they must find ways to use existing technology to preserve the genetic information of their own race..."
