"Everything about them is designed to withstand time," Xiang Shan said.
"Why do you say that?" Ingrid glanced at the notebook in her hand, and then looked carefully at the alien tablets.
"The fact that they chose this method to record information means that they were prepared for a voyage that lasted for a hundred thousand or even a million years - they were prepared with enough noise immunity to withstand the possibility of
All information present is lost."
What is the concept of "one hundred thousand years"?
A promising physicist once quoted the words of an ancient prophet, claiming that "the mountains flow in the presence of God." The properties of fluids and solids are related to the duration of the physical process. Under such a long time scale, hardness
The rocks can also show the characteristics of fluids, and the earth undulates in an orderly manner like waves. In one hundred thousand years, in places with intense orogeny, it is enough for thousands of meters of mountains to grow out of the flat land.
Over such a long period of time, the evolution of materials is a challenge that must be faced. Even the best materials cannot remain unchanged for a hundred thousand years in such an environment.
At this time, the most important thing is to be "big".
As long as the storage device is made large enough, the noise caused by material transmutation will be insignificant.
That's probably it.
"Actually, those guys store uranium-235 in the same way." Xiang Shan sighed: "Those aliens even considered at the beginning, 'What if Ogun's shell is penetrated by a meteorite and how to prevent uranium from hitting the fuel storage equipment?
There is a problem of flying uranium blocks. Many things inside Ogun are not resistant to ionizing radiation. Uranium blocks will affect the working efficiency of the drone."
"The spaces between the uranium blocks are filled with energy-absorbing materials with natural magnetism. Even if an interstellar meteorite crashes through Ogun, enters it, and happens to hit this pair of nuclear fuels, these nuclear fuels will not be rashly destroyed.
If it falls over, the lower-strength energy-absorbing material on the outside breaks first, but sticks as much as possible due to its own magnetism, or automatically accumulates on the steel column. David feels that considering the overall weight, this
It is a feasible method.”
"There is also this idea of using structural strength as a buffer for a hard landing..."
"But increasing the size like this will cause another problem."
"NASA surveyed the structure of this thing. They determined that there was originally a rocket section at the tail of Orgun, which should have been abandoned when it left its own solar system. Orgun is so big, and its materials can provide combat shear resistance.
Its performance is limited. Such a large spacecraft is very soft as a whole - Ogun can only maintain a low acceleration before leaving the home galaxy, otherwise it may deform itself!"
"And what does that mean? It means that it has to maintain a low acceleration for a long time - which is equivalent to leaving the atmosphere little by little at a very slow speed. It will go through a long acceleration period. In this process, the propellant
The consumption will be an astronomical figure!"
"The rocket that was abandoned by Ogun could not be bigger. Otherwise, the material would not be able to carry it anyway. But if the size of the abandoned rocket is limited, it means that Ogun's launch must be planned in advance.
I have refueled that rocket many times in my home galaxy..."
"This kind of forceful attack actually drove this huge thing to leave its home galaxy!"
"There are also machines...I am sure that those machines must be from some kind of self-replication. Their technology is not enough to support the machine running for such a long time. But I still haven't thought about how they did it - those aliens!"
Xiang Shan scratched his hair and confused the issue: "All the technologies of these guys are only slightly better than humans, and all technologies are within the current theoretical framework of humans and are completely understandable. But their behavior is so incomprehensible.
!Why does a civilization that is only slightly more advanced than human beings pay such a high price? Why does it build such a rocket? Why can it assemble such an engineering miracle?"
This is really a difficult puzzle to solve.
Until the 21st century, the two spacecrafts Voyager 1 and Voyager 2 as a whole project only spent 1 billion US dollars. In 1977, when Voyager 1 was launched, the national production of the United States was
The total value exceeds two trillion US dollars.
Compared with the total wealth of mankind, the cost of Voyager 1 and 2 is just a drop in the bucket.
But what about Ogun?
Even excluding the aspects of R&D and careful design, every step from construction to launch consumes manpower and material resources that are unimaginable to humans today.
Can humans do something similar?
It's probably possible.
But only if all human beings unite, completely ignore the general laws of production and economic activities, and invest in it regardless of the cost, can we build the "Ogun" that belongs to the earth within one generation.
As for why it is "a generation"?
If we put this time into "several generations", then technology will inevitably be upgraded.
When this project is finally completed, the gadgets launched by humans will definitely be much more advanced than "Ogun".
For the builders of "Ogun", what kind of magic does the starry sky have, is it worth doing this?
unless……
The technological level displayed by "Ogun", that is, the technological level that mankind is about to encounter, is the highest technological level that can be born from the paradigm of "science".
This universe can only support this level of technology.
This is a dark and miserable possibility.
After listening to Xiangshan's ramble, Ingrid said: "I think you don't need to be too pessimistic on this issue. Maybe the social structure of the Ogun builders is very different from that of us humans? For us humans, this kind of behavior
It's a little crazy, but maybe it's a normal thing in their culture?"
"ah?"
"Slaughter and blood sacrifice are of course quite uneconomical from an economic point of view. Why don't you keep those people as slaves and kill them? Especially the Third Reich, they even streamlined the killing -
If a slave owner from the slave era came here, he would probably express his incomprehension, right? But sometimes human beings need this kind of uneconomical behavior to maintain their self-identity."
Ingrid was quite satisfied with her conjecture: "Well, it sounds like a really crazy civilization. Let's write this down for now..."
Xiang Shan squinted at Ingrid writing and drawing in her notebook: "What are you looking at? Do you have a clue to decipher this language?"
