Chương 272: The second interstellar voyage
In the past 5 years, as the guards of the two sides gradually lowered, the high-level mutual visits of the two sides have become more frequent, especially the visits between scientists... Scientists must always
maintain strong curiosity about the outside world. Scientists are eager to experience life on a spacecraft in preparation for possible future interstellar voyages.
Of course, the Gliese people will bring some technology belonging to their own civilization in exchange every time.
After the necessary safety inspections and biochemical disinfection, soon, the group of Gliese people put on space suits, re-landed on the "Earth Times", and lived in their own living quarters.
This time, most of the guests who came from afar were mathematicians except for some politicians. The main topic they talked about was some conjectures about "transcendental numbers". They would live in the spaceship for half a year.
A small pangolin came on stage and introduced a new method of judging transcendental numbers.
Mathematics is always the same language of the universe. The four ancient civilizations of human beings all gave birth to their own mathematical systems when they were not connected with each other. As a kind of "high art", a civilization that cannot enjoy the pleasure of mathematics is absolutely ignorant and uncivilized.
But compared to the endless mathematical problems, there are too few mysteries that humans can solve.
To give a simple example, is π a transcendental number?
It can be proved that it is indeed a transcendental number.
Is Euler's constant e a transcendental number?
Of course it is, and it can be proved!
What about eπ?
The answer is: don't know.
Sounds like a simple question, but it is a world-class problem!
Even a mathematician like Zhang Yuan has no way of judging whether eπ is a transcendental number. Human mathematics can only solve a very limited number of problems until now. Even if a computer can calculate (eπ) to tens of trillions of significant digits, compared with infinity, it is not much different from zero.
The communication between civilizations can indeed rapidly promote the development of these disciplines.
The thinking between different civilizations is very different, and there are places to learn from each other. This kind of communication is not as simple as 11.
Of course, these mathematical problems, as far as they are concerned, can hardly affect the productivity of the entire society, at most they are equivalent to the self-entertainment of top scientists.
For the orbit of the aerospace vehicle with the highest precision requirements, the accuracy of pi is only 15 or 16 decimal places. Whether pi is a transcendental number or not does not matter much at all.
10 decimal places is enough to get the Earth's circumference accurate to within 1 inch! Thirty decimal places can make the circumference of the entire visible universe so accurate that even the most powerful microscope cannot distinguish it! Therefore, with regard to this knowledge, the two sides will openly share it with each other, and the high-level new civilization does not prohibit this kind of behavior, but encourages it faintly.
But why judge solving these seemingly insignificant math problems?
Because...
it's right there!
"...The above is our latest research about a method of judging transcendental numbers. Thank you for listening, thank you."
There was thunderous applause, and there was an endless stream of discussions. Flash dance was able to receive warm applause, which shows that this speech is still very popular.
And this group of pangolins has also become accustomed to human etiquette and communication methods. They wear space suits and look very satisfied after being praised.
"Professor Anbogu, I have a slightly different opinion about your deduction 314..." Zhang Yuan stood up and raised several doubts, all of which were well answered.
After the first exchange meeting, these Gliese people will have more than ten days of rest before the second and third exchange meetings. Human beings have long been accustomed to their work and rest.
Zhang Yuan didn't want to wait another ten days. When the other party returned to the living area, he followed him and asked: "So, Your Excellency Gan Yaduo, what interesting trading ideas did you think of during your visit? Why don't you tell me first, let We have a mental preparation."
"As long as it meets the demands of both parties, I believe there is still a lot of room for negotiation..."
There are many things that human beings lack at present, such as smart phones, which can significantly improve the quality of life of ordinary people, but they are fundamentally lacking. It is not the focus of the development of new civilization.
Buying some from the Gliese Civilization is also a good option.
There are also some high-end robot chips and high-precision parts. If the Gliese people can produce them on their behalf, then the development of human beings will be smoother and the progress will be faster.
Most of what humans pay is entertainment products and their own technological background.
In practice this exchange is acceptable.
This time, the other party brought a lot of goods, including more than 10,000 traditional silicon-based chips. This amount is not too much compared to human needs, but it can be regarded as a good opening.
Scientists are testing the quality of these products and researching compatibility issues.
Gan Yaduo turned his head, because it hadn't slept for a long time, it felt a little bit tired.
It solemnly said: "Your Excellency Zhang Yuan, our biggest request is a stellar-class spaceship... Everything else is easy to say, it's just an add-on to this spaceship.
" The mothership is enough to take on the heavy responsibility of restarting a civilization without letting the entire civilization go extinct on a different planet."
"And we also need technologies related to interstellar colonization, such as space elevators, the construction of large centrifugal wheels, and the construction of ecological circulation systems... We must at least learn how to maintain spaceships?" These knowledge must be very expensive, new human
civilization It is impossible to sell at a low price, so it can only be traded bit by bit. Including those chips that were brought up also belonged to the scope of the transaction.
Zhang Yuan nodded and said, "I'm sorry, personally, I really want to facilitate the biggest deal, to build a giant mothership to help you leave this planet..." "But limited to productivity,
we Such a giant spaceship cannot be produced for the time being, even if human beings develop very smoothly, it will be one or two hundred years later. We cannot promise something in a few hundred years... This is the responsibility of both parties." Gan Yaduo
pointed Foot: "No, no, I mean, how long is your current mothership, the Earth Age, still in service?" "
Service period?"
This topic is a little sensitive, but it's okay to reveal a little information, Zhang Yuandao: "It depends on how the specific maintenance is. The main frame of this spaceship is metal with high strength. If it is placed in space, it will not change for thousands of years." "The bearing of the centrifugal
wheel There may be some wear and tear... and the radiation protection layer and airgel layer in the living area have a shorter lifespan. The outer surface is a flexible material, almost fifty years." "There are also some electronic devices that have a shorter lifespan
. It will have to be replaced in a few years or a few decades..." "
So, its service life is at least fifty years."
So, if human beings develop with peace of mind for a few decades, the world will already be turned upside down With the changes, human beings will gradually live on the surface.
This original mothership will also be phased out gradually. It is impossible for human beings to live in the spaceship forever. This is an inevitable event.
"So, is it possible to complete an interstellar journey again?"
"You mean..."
Zhang Yuan was slightly startled, and soon thought of a possibility.
Does this guy... want the Earth Age ship?
Of course, not now, but waiting for decades, after all human beings have moved underground and eliminated this spaceship... The
Gliese people have a lot of patience to wait.
Seemingly seeing Zhang Yuan's doubts, Gan Yaduo explained: "We will choose a closer planet as an immigration point, and strive to complete this interstellar journey within 500 to 1,000 years... Correspondingly, we need The spaceship must also have such a high service life."
"Buying a second-hand spaceship is almost our minimum requirement, and I hope you can carefully consider our request."
Watching the leader leave, Zhang Yuan felt deeply in his heart. I kept thinking about it.
This idea seems... not impossible!
It can even be said... the feasibility is very high!
He quickly brought the news back to the captain's room.
"What?"
After hearing what Zhang Yuan said, everyone jumped up in surprise. Even Captain Zhao was taken aback.
Re-manufacturing a spacecraft that travels between stars may take one or two hundred years of human development, consume huge productivity, and even delay the development of other industries. So after much deliberation, a little reluctant.
Even if you get a universal factory, you have lost too much.
However, if the Earth Age is only to be renovated on a large scale, the amount of engineering and difficulty required will be much smaller, and perhaps only thirty or forty years of development will be enough!
"Manufacturing and refurbishment are two completely different difficulties. The skeleton of the Earth Age is complete. If it is refurbished, it is not impossible to complete another interstellar journey."
Captain Zhao frowned, and said: "From an economic point of view, it is definitely feasible... If our population has been completely relocated in a few decades, it is nothing more than a huge profit if we use it to replace a universal factory. Point!"
"After all, the Earth Age is the technology of 3,000 years ago. Now, we will definitely be able to build a better and more excellent mothership."
Zhang Yuan also agreed: "It's equivalent to their retreat. Take a big step, from the new spaceship that was originally needed, to a second-hand spaceship... Let's do the math, how much work will be required to completely renovate the Earth Times, and how much time can we earn?
" , Everyone fell silent. If you want large-scale repairs, you must first have a large enough star port and build a repair dock.
"It is estimated that this production target will be completed in 20 years."
But the Earth Age is indeed too old, and if you want to continue the next journey into the starry sky, it must be completely overhauled. Except for some frame skeletons that do not need to be modified, the rest of the parts, including the living area, bearings, heat dissipation area, and central control area, all have to be repaired.
One of the experts said: "...allocate a certain production line and add 80,000 people to this repair work. It is conservatively estimated that the repair work should be completed in 20 years. Some computers in the core area are degraded. It saves a lot of trouble for people to participate in the manufacturing."
"20 plus 20, that is, it will take at least forty years to complete this transaction..."
Forty years, what a long number!
But it took forty years to complete this deal, and it was still very cost-effective for human beings. At that time, the population was less than five million, and the combined productivity of all people might not even be comparable to a universal factory.
"Even without this deal, humans still have to build functional buildings such as star ports and shipyards." "
So, at most, it's just some repair work."
That's right!
Zhang Yuan suddenly asked Professor Xiang Yamamoto, "After forty years of effort, can you develop virtual technology, and then slowly guide and seduce all the Gliese people in the remaining 12 cities into the virtual world?" "If there
is We bought 12 universal factories, and we don't have to deal with the troublesome business of this one, and we can even snatch it directly..."
After hearing Zhang Yuan's proposal, the conference room fell into silence for a while.
Li Zhendong, who was sitting next door, couldn't help scratching his head with his fingers, Zhang Yuan, why did he have... so many bad ideas?
He, Li Zhendong, still has to be shameless... He was holding a very friendly math meeting a few minutes ago, and secretly discussing how to rob others a few minutes later. This is really difficult to do.
No, it can even be said that the entire human civilization needs face!
It's not a big psychological burden to send those drunken and dreamy guys into the virtual space, but now... Goer City is the last hope of this civilization!
"Okay, it's my fault..." After some calculations, Zhang Yuan rejected the plan on his own.
"Although this plan will bring short-term benefits, in the long run, plundering will cause unfriendly deviations in the ideology of the people, and it will not be conducive to the ruling philosophy of our entire school..." "If we have 12 universal
factories , There is no need to snatch others for one..."
Greed is not a big mistake, but insatiable greed is always a sin.
Immediately afterwards, Zhao Qingfeng vetoed Zhang Yuan's plan from another angle: "Even if this technology is successfully developed, forty years is definitely not enough!
" Same. We think forty years is a long time, but they don't think so at all. Forty years is about the same as our four years, and it's impossible to produce a huge ideological shift."
"So, even if virtual technology comes out, it is impossible to completely brainwash them in just forty years..." "
One or two hundred years is about the same..."
Zhang Yuan agreed with this point of view: "Well, that is, the time is completely different." Is it allowed... Then, within 40 years, try to get this universal factory that is the easiest to obtain first, and it would be good to leave a kindling for the Gliese civilization. Hey, let's leave it at this, this disaster-ridden civilization. "
Everyone breathed a sigh of relief inexplicably, and began to discuss the next construction rectification.
After pondering for a while, Captain Zhao thought of something again, and said with a wry smile: "Everyone, if you use the spaceship 'Earth Times' to trade, I'm worried about another point." "That's the problem of public sentiment
. The thinking of our group of people is a little different from that of ordinary people." "
From a purely utilitarian point of view, it is indeed the best choice to renovate and sell it, and there is no big problem." "
But the public can I can't care so much, I can already expect this kind of opposition from all over the mountains and plains. This mothership has accompanied us for three thousand years... The long road to the stars has finally reached its destination and accompanied us to develop. This alien planet has gained a foothold."
"After draining the last remaining value, it will be sold again? What's the difference between this and selling your old mother?" "That's
right!" Informatics scientist Li Zhendong knocked on the table, then touched his chest, "I said, I always feel something is wrong, so it is so! So this plan is not easy to pass!" Zhang Yuan sneered, "Sell
yourself The old mother? This kind of statement is really stupid... No, emotional!" "
Then you say, what is the use of this spaceship after all the population has been relocated to the surface? It can still be used as a space elevator now, but after the construction of the Starry Sky Port is completed , The space elevator is not used as a space elevator, just put it aside and let it be scrapped? Or use it as an amusement park or a museum?"
"It will just slowly wither and die there!"
"Hundreds of years later, will anyone still remember its existence?"
A deputy captain interjected: "At least it can bring a sense of security. For the public, It's good to leave it there to wither... People will be reluctant to leave it there and think it's better than selling it."
"What's the sense of security? If there is a real war, it can still take everyone away. ? We can develop specialized interstellar war weapons, rail guns and drones, and still need this scrapped mothership?!"
Zhang Yuan found himself a little emotional, and cleared his throat quickly.
He said excitedly: "In fact, the issue of public opinion is very simple. I thought of a propaganda slogan: Instead of letting our mothership lie idle here and die alone, it is better to let her carry the hope of another civilization, and once again ..."
"Set sail!"
"Completing her own glorious journey, a journey of... salvation for a civilization, this is the greatest meaning of her existence!"
