Wandering Spaceship in Deep Space Chapter 274: The second interstellar voyage (2 in 5000 words!)

In 5 years, as both sides gradually lowered their guards, high-level visits between the two sides have become more frequent, especially visits between scientists...

Scientists have to maintain a strong curiosity about the outside world. Scientists from Goer City are eager to experience life on a 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 going through the necessary safety tests and biochemical disinfection, soon, these Gliese people dressed in spacesuits landed on the "Earth Age" again and lived in their own living quarters.

The guests who came from afar this time, except for some politicians, are mostly mathematicians. The main topic they talked about is some conjectures about "transcendence number". They will live in the spacecraft for half a year.

A small pangolin came on stage and introduced a new method of judging transcendence.

Mathematics will always be the same language in the universe. The four ancient civilizations of mankind have all given birth to their own mathematical systems when they are not connected to each other. As a kind of "elegant art", a civilization that cannot enjoy the fun of mathematics is absolutely ignorant and uncivilized.

However, there are too few mysteries that humans can solve for the endless comparisons of mathematical problems.

For 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 can be proved!

What about eπ?

The answer is: I don’t know.

A question that sounds simple, but a world-class problem!

Even a mathematician like Zhang Yuan has no way of judging whether eπ is a transcendental number. The development of human mathematics to the present can only solve quite limited problems. Even if a computer can calculate (eπ) to tens of trillions of significant digits, it is not much different from zero when compared to infinity.

The exchange of civilization and civilization can indeed quickly promote the development of these disciplines.

The thinking between different civilizations is quite different, and there are places to learn from each other. This kind of communication is not as simple as 11 years.

Of course, these mathematical problems, for now, are difficult to affect the productivity of the entire society, at most equivalent to the self-entertainment of top scientists.

The orbit of a spacecraft with the highest precision requirements has a pi accuracy of 15 or 16 decimal places. It doesn’t matter whether the pi is a transcendental number at all.

10 decimal places are enough to make the earth's perimeter accurate to within 1 inch! Thirty decimal places can make the entire periphery of the visible universe accurate to an amount that even the most powerful microscope can't distinguish! Therefore, regarding this knowledge, the two sides will openly communicate with each other. The new civilization senior level does not prohibit such behavior, but implicitly encourages it.

But why do you judge and solve these mathematical problems that don’t seem to matter?

Because...

It's right there!

"...The above is our latest research, about a way of judging beyond numbers, thank you all for listening, thank you."

There was thunderous applause from the bottom, and the voice of discussion was endless. Flash dance was able to receive warm applause, which shows that this speech is still very popular.

And these pangolins have also become accustomed to human etiquette and communication methods. They are wearing spacesuits, and after being praised, they look quite satisfied.

"Professor Anbogu, I have a slightly different view on your inference 314..." Zhang Yuan stood up, raised a few doubts, and received good answers.

After the first exchange meeting, this group of Gliese people will have more than ten days of rest, and then they will have the second and third exchange meetings. Humans have long been accustomed to their work and rest. Up.

Zhang Yuan didn’t want to wait for more than ten days. When the other party returned to the living quarters, he followed up and asked: “Then, Lord Gan Yaduo, what interesting trading ideas did you think of during your visit this time? Say, let us be mentally prepared."

"As long as the demands of both parties are met, I believe that 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 not the focus of the development of a new civilization.

It is also a good choice to buy some from Gliese Civilization.

There are also some high-end robot chips and high-precision parts. If Gliese people can produce them, then human development will be smoother and the progress will be faster.

Mankind pays mostly entertainment products and their own technological heritage.

In fact, this kind of 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 studying compatibility issues.

Gan Yaduo turned his head, because he hadn't been dormant for a long time, he felt a little tired.

It said solemnly: "Your Excellency Zhang Yuan, our biggest appeal is a stellar-class spacecraft... everything else is easy to say, it's just an add-on to this spacecraft."

"You also know that only a mothership like the Earth Age can take on the heavy responsibility of restarting a civilization without letting the entire civilization go extinct on another planet."

"Moreover, we also need technologies related to interstellar colonization, such as space elevators, the structure of large-scale centrifugal wheels, the structure of ecological circulation systems... We must at least learn to repair spacecraft, right?"

This knowledge must be very expensive, and the new human civilization cannot be sold at a low price, so it can only be traded bit by bit slowly. Including those chips that are brought up, also belong to the category of transactions.

Zhang Yuan nodded and said: "I'm sorry, as far as I am concerned, I really want to facilitate this biggest deal and create a giant mothership to help you leave this planet..."

"But limited to productivity, we cannot produce such a giant spacecraft for the time being. Even if humanity develops very smoothly, it will be a matter of one or two hundred years from now. We cannot promise something hundreds of years from now... this is Responsible to both parties."

Gan Yaduo pointed to his feet: "No, no, no, I mean, how long is the service period of the Earth Age, your current mothership?"

"Service period?"

This topic is a bit sensitive, but it’s okay to reveal a little information. Zhang Yuan said: "It depends on how the specific maintenance is. The main skeleton of this spacecraft is high-strength metal. If it is placed in space, There will be no change for thousands of years."

"There may be some wear on the bearing of the centrifugal wheel... But the radiation protection layer and aerogel layer in the living area have a shorter life. The appearance is a flexible material, almost fifty years."

"Some electronic devices have a shorter life span. They will have to be replaced after a few years or decades..."

"So, its service period, at least 50 years of life span."

So, if mankind develops peacefully for several decades, it will already be earth-shaking changes, and mankind will gradually live up to the surface.

This original mothership will also be gradually eliminated. It is impossible for humans to live in the spacecraft all the time. This is an inevitable event.

"So, is it still possible to complete an interstellar journey again?"

"Do you mean..."

Zhang Yuan was slightly startled, and soon thought of a possibility.

Does this guy... want the Earth Age spacecraft?

Of course, not now, but waiting for decades, waiting for all human beings to move underground and eliminate this spacecraft...

Gliese people have to wait patiently.

Seeing Zhang Yuan’s doubts, Gan Yaduo explained: "We will pick a planet a little closer as an immigration point, and strive to complete this interstellar journey within five hundred to one thousand years... Correspondingly, The spacecraft we need must also have such a high service period."

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

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

This idea seems to be...not infeasible!

It can even be said...the feasibility is great!

He soon 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.

It may take one or two hundred years of human development to rebuild a spacecraft that sails between stars, consume huge productivity, and even delay the development of other industries. So after thinking about it, I was a little reluctant.

Even if you get a universal factory, you lose too much.

However, if only the Earth Age is to be renovated on a large scale, the amount of engineering required and the difficulty will be much smaller, perhaps only 30 to 40 years of development will be enough!

"Manufacturing and renovation are two completely different levels of difficulty. The skeleton of the Earth Age is complete. If it is renovated, it is not impossible to complete an interstellar journey."

Captain Zhao frowned, and said: "From an economic point of view, it is definitely feasible... If our population has been completely relocated after a few decades. Using it to replace a universal factory is a big profit. Can’t make too much money!"

"Earth Age is technology three thousand years ago after all, and now, we will definitely be able to build a better and better mothership."

Zhang Yuan also agreed: "It is equivalent to a big step back. They replaced the new spacecraft originally needed with a second-hand spacecraft... Let’s do the calculations. The Earth Age should be completely renovated. How much work and how much time can we earn?"

For a while, everyone fell silent. For large-scale repairs, first there must be a large enough starry sky port to build a repair dock.

"It is estimated that this production goal will be completed in twenty years."

But the Earth Age is indeed too old. If you want to continue the next starry sky journey, it must be overhauled. Except for some frameworks that do not need to be modified, the rest, including the living area, bearings, heat dissipation area, and central control area, must all 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 these repairs should be completed in 20 years. There are some core areas of the computer. The Gliese people themselves participated in the manufacturing, which saved a lot of trouble."

"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 transaction. It is still very cost-effective for humans. At that time, the population was less than 5 million. The combined productivity of all people may not be as good as a universal factory. .

"Even without this transaction, humans still have to build functional buildings such as the starry sky port and the dock."

"So, at most, only some repair work."

That's right!

Zhang Yuan suddenly asked Professor Xiang Yamamoto, "Forty years of work, can you develop virtual technology, and then slowly guide and tempt you to send all the Gliese people in the other 12 cities into the virtual world?"

"If there are 12 universal factories, we can skip this troublesome business at all, and we can even grab it directly..."

After listening to Zhang Yuan's proposal, the meeting room fell silent for a while.

Li Zhendong, who was sitting next door, couldn't help but scratched his head with his fingers, Zhang Yuan, why...so many bad ideas?

He Li Zhendong still has to shame...The math meeting was held in a very friendly manner in the first few minutes, and in the next few minutes he secretly discussed to **** others. This is really difficult to do.

No, it can be said that the entire human civilization needs face!

Sending those drunken and dreamy guys into the virtual space, there is not much psychological burden, but now... Gore City is already the last hope of this civilization!

"Well, 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 people's ideology, and it is not conducive to our entire school's governing philosophy..."

"If we have 12 universal factories, there is no need to grab someone else's for one..."

There is nothing wrong with being greedy, but being greedy is always a sin.

Immediately afterwards, Zhao Qingfeng rejected Zhang Yuan’s proposal 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 Gliese people are different from ours. We think that forty years is a long time, but they don’t think so. Forty years are about the same as our four years. It is impossible to produce a huge ideological change."

"So, even if the virtual technology comes out, it is impossible to completely brainwash them in just forty years..."

"One or two hundred years is still about the same..."

Zhang Yuan agreed with this point of view: "Well, time is not allowed at all... Then within 40 years, first try to win this most easily available universal factory and leave it to Gliese civilization. A kind of fire is also good. Hey, so be it, this tragic 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 the spacecraft'Earth Age' is used for trading, there is another thing I worry about."

"It is the issue of folk emotions. 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, there is no big problem."

"But the people can't control so much. I can already expect this kind of opposition. This mothership has accompanied us for three thousand years... The long way to the stars has finally reached its destination. Accompany us to develop and gain a foothold on this alien planet."

"As a result, after squeezing the last bit of surplus value, I want to sell it again? What is the difference between this and the old mother who sold me?"

"That's right!" Li Zhendong, an informatics scientist, knocked on the table and touched his chest. "I said, it always feels a little bit wrong, it turned out to be like this! So this plan is not easy to pass!"

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

"Then you said, after all the population is moved to the surface, what is the use of this spacecraft? It can still be used as a space elevator, but after the construction of the Star Harbor, the space elevator will not be used as it. On the one hand, let it be scrapped? Or as an amusement park or a museum?"

"It will only slowly wither and die there!"

"Hundreds of years later~IndoMTL.com~Does anyone remember its existence?"

A deputy captain interjected: "At least it can bring a little sense of security. For the people, it is good to leave it there and wither... People will feel reluctant, and feel that even if it is left unused, it is better than selling. Good."

"What sense of security? If there is a war, it can still take everyone away? We can develop special interstellar warfare weapons, railguns and drones, and we need this scrapped ship. Mothership?!"

Zhang Yuan found that he was a little agitated, and quickly cleared his throat.

He exclaimed: "In fact, the issue of public opinion is very simple. I thought of a propaganda slogan: Instead of letting our mothership sit idle here and die alone, let her carry the hope of another civilization. , Again..."

"Set sail!"

"Completing her own glorious journey, a journey of salvation for a civilization, this is the greatest significance of her existence!"
