Deep Space Fleet

Biquge www.xbiquge.bz, the fastest update of Wandering Fleet in Deep Space!

In the past five years, as the guards of the two sides have been 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 from Goeer City are eager to experience life on the spacecraft and prepare for possible interstellar voyages in the future.

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 common language in the universe. The four ancient civilizations of human beings all gave birth to their own mathematical systems without contact 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 e+pi?

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 e+π is a transcendental number. Human mathematics can only solve quite limited problems until now. Even if a computer can calculate (e+π) 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 1+1.

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. Being able to receive warm applause 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 3.1.4..." 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 are mentally prepared."

"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 humans currently lack. For example, smart phones can significantly improve the quality of life of ordinary people, but they are not the focus of the development of new civilizations at all.

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 appeal is a star-level spaceship... Everything else is easy to say, it's just an add-on to this spaceship."

"You also know that only a mothership like the Earth Age can take on the important task 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, right?"

This kind of knowledge must be very expensive, and it is impossible for the new human civilization to sell it cheaply, 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 this biggest deal, to build a giant mothership to help you leave this planet..."

"But limited by productivity, we are temporarily unable to produce such a giant spaceship. Even if human beings develop very smoothly, it will be a hundred or two hundred years later. We can't promise something in a few hundred years... This is for both parties Responsible."

Gan Yaduo pointed to his feet: "No, 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 not a big deal to reveal a little information. Zhang Yuan said: “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 last thousands of years. Nothing will change for tens of thousands of years.”

"There may be some wear and tear on the bearings of the centrifugal wheel... and the radiation protection layer and airgel layer in the living area have a shorter lifespan. The outer surface is made of flexible materials, about fifty years."

"There are also some electronic devices that have a shorter lifespan, and have to be replaced after a few years or decades..."

"So, its service period, at least fifty years of life."

Therefore, if human beings develop with peace of mind for several decades, it will already be earth-shaking changes, and human beings will gradually become livable to 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?"

"what do 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...

Gliese people have plenty 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 spacecraft must also have such a high service life."

"Buying a second-hand spaceship is almost our minimum requirement. I hope you can consider our request carefully."

Watching the leader leave, Zhang Yuan kept thinking in his heart.

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 Era 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 a big step back for them, replacing the new spaceship they originally needed with a second-hand spaceship... Let's do the math, how much work will it take to completely renovate the Earth Times?" How much time can we earn?"

For a while, 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 it must be completely overhauled if it wants to continue the next journey into the starry sky. 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 themselves.”

"20 plus 20, that is, will it 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 humans. 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 docks."

"So, at best, it's just some repair work."

correct!

Zhang Yuan suddenly asked Professor Xiang Yamamoto, "In 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 are 12 universal factories, we don't have to do the troublesome business of this one, and we can even snatch it directly..."

After listening to Zhang Yuan's proposal, the meeting 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 too much of a 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 rob others for one..."

There is nothing wrong with being greedy, 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 will definitely not be enough!"

"You have to know that the work, rest and life cycle of the Gliese people are different from ours. 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, it is impossible There was a huge ideological shift."

"So, even if virtual technology comes out, it's 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, time is not allowed at all... Then within 40 years, try to win this universal factory that is the easiest to obtain, and leave a kindling for the Gliese civilization. Not bad. Hey, that’s it, this troubled civilization.”

Everyone breathed a sigh of relief inexplicably, and began to discuss the next construction rectification.

After thinking 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 have another point of worry."

"That's the problem of folk sentiment. The thinking of our group of people is always a little different from that of folk 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 people can't control so much. I can already expect this kind of opposition voices from all over the mountains. This mothership has accompanied us for three thousand years... The long road to the stars has finally reached its destination and accompanied us again. It developed and gained a foothold on this alien planet."

"As a result, after squeezing out the last bit of residual value, you have to sell it again? How is this different from selling your old mother?"

"That's right!" Li Zhendong, an information scientist, knocked on the table and touched his chest. "I said, I always feel something is wrong. It turns out to be like this! So this plan is not easy to pass!"

Zhang Yuan sneered, "Sell your old mother? This kind of argument is really stupid... No, emotional!"

"Then tell me, 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, it will not be used as a space elevator. Just put it aside like this. Scrap it? Or use it as an amusement park or a museum?"

"It will just wither and die there!"

"Hundreds of years later, does 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 put it there to wither... People will be reluctant, and they will think that even if they are left idle there, it is better than selling it."

"What sense of security? If there is a real war, can it 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 emotionally agitated, and quickly cleared his throat.

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 ..."

"start sailing!"

"Completing her own journey of glory, a journey of... salvation for a civilization, this is the greatest meaning of her existence!"
