"Artificial Earth" was a side project during the construction of Deep Space.
Human beings are not satisfied with the original ecological environment of Noah, so they have always been ambitious to change it...
I want to transform it to look like the real earth!
According to people's plans, natural environments such as forests, seas, rivers, clouds and rain will appear in different areas of Noah. These natural environments constitute a complete set of "carbon cycle" and "water cycle".
The huge energy provided by nuclear fusion is used to support the stable operation of these ecosystems.
After such a long period of transformation, forests, rivers, clouds and rain have indeed appeared, and it looks quite good.
Only...the sea is not perfect enough.
The water resources of the "artificial sea" are taken from the Nix star, which is equivalent to the water volume of 260 Taihu Lakes. However, this sea looks lifeless, without a single ripple.
This is because there is no moon. Without the tidal gravity provided by the moon, the sea would not have waves, and it would only be calm...
The so-called "Gold Coast" has never been very beautiful.
Artificial is still inferior to nature.
Everything human beings derive from nature and learn from nature. But no matter how advanced technology is, it cannot replace nature.
In order to improve this lifeless sea, several young engineers had an idea and came up with a good idea...
Today happens to be a rest day. There are men and women on the Gold Coast, as well as a large number of children running and playing.
This is a time of leisure and rest, when everyone feels very relaxed.
Of course, this kind of relaxation is related to the smooth sailing of the Deep Space. If something really happened, no one would be in the mood to play.
There is no sun inside the Noah, so it relies entirely on lights. However, the effect of these special lights is similar to that of the sun, and it shines warmly on the body.
The most important thing is that there is a huge waterfall hanging from the sky!
With a height of two thousand meters, it made a huge noise in the distance and finally stirred up the lifeless sea water.
The appearance of a waterfall makes the ocean come alive.
Many children were screaming and rolling around in the waves, very happy.
This is the method those young engineers came up with, and the effect... is really good!
"A certain river on the upper floor changed its course and flowed directly from the ceiling. The drop is nearly two thousand meters."
"It's a good idea. With this waterfall, this place will be much more beautiful."
Yu Yifeng said with a smile. Seeing so many children, he was in a good mood.
He took Yuriko, avoided the busy area, and directly found a remote corner to sit down.
He took out another piece of gauze from his bag, laid it out, and poured two glasses of red wine on it himself.
Yuriko took out some simple breakfasts and put them one by one on the gauze.
She looked very happy.
"But this seems to be treating the symptoms rather than the root cause...Other places are still calm and there are no waves. The fluctuations are just surface water splashes."
"Yes, unless we put a lot of effort into stirring up the entire seawater with a large machine, we can simulate real tides...but it seems that there is no need." Yu Yifeng smiled and said: "If I let you design it, what would you do?"
Yuriko thought for a while and said directly: "We can use the residual temperature of the nuclear fusion reactor to heat the ocean and accelerate the water circulation process."
"You can also modify the seafloor results and use thermodynamics to create certain ocean currents."
Yu Yifeng smiled and said: "If it were me, I could just explode a small-yield nuclear bomb directly on the seabed. It would also cause big waves."
"You really have no artistic talent!"
The two of them talked about each other, and for them, this kind of conversation was already normal.
After quickly finishing the simple and sweet breakfast, Yu Yifeng patted his belly and put on a pair of sunglasses.
The upper space of this place has been greatly opened up, and the lights are at a very high position, making it really look like the sun.
At this time, Yuriko was quite well prepared. She found a dry place, laid out two bath towels, and leisurely basked in the sun.
The light here is never too poisonous, a bit like the sun in winter, so there is no need to apply sunscreen. The temperature has always been maintained at 28-30 degrees Celsius, which is slightly hot, and a piece of clothing is enough.
From this perspective, it is more comfortable than any resort on earth...
The two of them lay quietly like this, listening to the sound of the waterfall and watching the people playing in the distance.
The days are very leisurely...
Yuriko suddenly turned her head and said: "I have a question, why are we looking for the next Earth? Isn't this a good place? For them, the Earth is not necessarily as comfortable as the current Noah."
"The next few generations have never seen the real earth..."
This is a question. Yu Yifeng was stunned for a long time and replied: "Yes, it is precisely because of this that we want to let them see our former hometown. Maybe it is the obsession of our generation, maybe it is also the obsession of the entire human race.
Obsession..."
"Humanity... ultimately comes down to the earth."
"And I always believe that artificial things are not as good as natural ones..."
Yuriko was obviously dissatisfied with this answer. She shook her head: "Even if we find it, it's not the real Earth...it's just a strange planet."
"The real earth has been destroyed, and we have no ability to restore it..."
Yu Yifeng was suddenly stuck. He didn't know how to answer, but he didn't think that human beings' search was wrong.
He even recalled the scene when he was young and played in the real sea...
The earth period only occupied a small part of his long life, but it was so important.
This emotion is very strange, it is difficult to explain exactly why...
Is it a feeling of homesickness? Or... the fallen leaves of life are returning to their roots?
"We belong to the earth, maybe it's engraved in our genes..." Yu Yifeng said quietly.
Yuriko smiled and asked: "Let's not talk about this for now... What are you going to do after you find the new earth? Will you continue to be your leader? This period of time may be very short, a few years is enough, or it may be very, very long.
…”
Yu Yifeng was silent for a long time, not knowing how to answer.
"I've found a new Earth... Maybe I'll quit this job... How about we become scientists together?"
"Ignore the rest? That's not a good idea, they can't do without you..." Yuriko said with a smile. After hearing this answer, she was in a very good mood.
Yu Yifeng hesitated for a moment: "Yeah, it doesn't seem possible... Even if we are already an interstellar civilization, our fundamental goal is still survival and reproduction."
"Our life is quite beautiful, technology is advanced enough, and we have almost unlimited energy..."
"It seems there is nothing to worry about."
"According to this, if the environment is too comfortable, our progress will stop? So... interstellar civilization may also fall into the trap of comfort."
He smiled self-deprecatingly: "In cosmic sociology, this is a process of increasing civilization entropy, called the theory of increasing civilization entropy. Haha... This concept was proposed by the alien Hei. When we are poor, can we
We can endure hardships and stand hard work through hard work, but when we are rich, what is the reason for hard work?"
Lily Zi shook her head and disagreed with Yu Yifeng's point of view: "Your statement may not be correct. For many people nowadays, it is no longer enough to just survive and reproduce as they used to."
"For them, studying science is as important as life...so it should be a good goal to keep improving science and technology."
"To be more precise... explore the unknown! Such a philosophical goal should be more powerful than survival and reproduction. Our education system and cultural atmosphere are gradually changing in this direction."
"Yes... you are right." Yu Yifeng nodded: "This is also where our civilization has made progress over the past hundred years."
"But if it becomes more and more difficult to explore science, and even a lifetime of study will not allow us to learn the knowledge of our predecessors, then... this philosophical goal will gradually become ineffective."
Yuriko whispered, ": This period of time is still very far away... isn't it? Completing the science tree is too far away, tens of thousands of times further away than realizing nuclear fusion..."
The whole topic seemed very strange, but the two of them naturally thought deeply about it.
After a long time, Yu Yifeng suddenly realized that he was here for a vacation, not to think about philosophical issues...
He suddenly sat up from the beach. Just lying like this was a bit boring.
He looked at the entertainment crowd, then at Yuriko, and suddenly asked curiously: "Why don't you wear a bikini? You should wear this in a place like this..."
"How about we go swimming?"
"I don't want it!" Her face was slightly red. With a serious personality like hers, how could she wear something like that...
Seeing her lying there, she was dressed very conservatively, but Yu Yifeng clearly knew that there were irregularities hidden in the clothes.
Suddenly something moved in his heart. Since receiving the perfect element, the girl has become more beautiful and has better physical fitness. She can...
He quickly pulled out a simple tent from the bag.
"What are you doing with a tent? Why would you bring something like this?" Yuriko asked curiously.
"Want to achieve a genetic goal!"
"What?" She was stunned. After a few seconds, she finally understood what Yu Yifeng meant, and her skin turned red with embarrassment. "But in a place like this..."
"No one knows!" Yu Yifeng set up the tent, yelled, and pulled her in...
