Evening smiled. "Don’t look at me like that. You know, my major is astronomy. My graduation thesis in that year was the study of extraterrestrial water-bearing planets. Let’s get back to the topic. Even with such a low proportion of one thousandth, the ocean occupies most of the earth’s surface. If we assume that even if a planet’s water weight is two thousandths of the planet’s total weight, then it is impossible to see the mainland according to the general principle. If the planet’s water content rises a little, even the islands will disappear, that is to say. For all liquid water planets, a large area of land is a small probability event, and it is a normal state that the surface base is covered by the ocean. In fact, so far, humans have discovered that one of the more than 200 extraterrestrial life planets has a large area of land. "

"Where?" Yelena irrepressibly asked
"It is the starfish that I have lived in for 20 years. Its surface is covered by 90% of the ocean, and there is an area close to the Asian continent. When it was discovered, it attracted attention. It was the former Human Rights Commission that launched the most urgent plan."
"What? Because it has land? " Fan Zhe interjected.
"Can there be other reasons? Is because of the land "evening nodded affirmatively.
(5) Optimists
The spacecraft has entered the low-earth orbit. Seen from here, Bohai Star occupies more than half of the field of vision. It quietly rotates with wisps of clouds and broken chains to outline the general atmospheric movement pattern. Yelena’s eyes have scanned a console. The signal has been sent but has not yet received a response. This seems to be somewhat abnormal. After the wormhole transition, it will take about four days to reach Bohai Star astronauts for training. This is the routine voyage preparation. Yelena turned to enjoy the scenery outside the porthole. She already knew that because there was no such thing. The climate of Bohai Star on the mainland is mild, except for the occasional typhoon near the equator. There is no extreme weather condition on the base. Because there is no blocking and reducing effect on the mainland, the duration of typhoon Bohai Star is much longer than that of the earth, but even the typhoon does not pose much threat to the biosphere. Huge amounts of liquid water protect all creatures, but is this really protection?
"I still doubt that the water planet can block the generation of intelligent life forever." Yelena looked at Xi. "If there is enough time, maybe life will find an unknown evolutionary path."
"Time is not a problem. Some small-mass stars can be stable for tens of billions of years, but can you tell me how the water planet can get fire? It is not fleeting, like flashing, but can be made to burn continuously." The evening sound becomes low. "The three conditions of combustion are that there are combustible materials, oxygen contact, and the temperature reaches the ignition point of combustible materials. There is no free oxygen in the water and the water temperature is lower than the ignition point of most combustible materials. The natural condition method to get fire is actually based on the ingenious design of machines. This kind of fire is a product of wisdom."
Yelena shook her head in frustration. Of course, she knew the significance of fire to the evolution of intelligent life. It was not only the protection and cooked food, but also all the technologies including calciner, metal smelting and later human chemistry and physics.
"There used to be a view that the symbol of human intelligent life is that the proportion of human brain weight is the highest, but now we know that bottlenose dolphins are larger than human beings, but bottlenose dolphins have not been able to produce their own culture for millions of years, which is at most a rudiment of society." Xi went on to say, "So you can now see that when the starfish was discovered in the past, the earth was on the verge of an enemy, because the mainland is likely to lead to intelligent life, but it is a false alarm. Starfish has no high intelligent life, and the highest species there is a kind with a spine and six. Brachiopod land octopus intelligence is close to that of the earth gibbon. If humans discovered the starfish later, this creature might become the ruler of the planet, but now their brachiopods are a famous dish of the starfish. "
Yelena can’t help but feel great pride and celebration. If we accept the argument that the water planet will eventually become an almost eternal imprisonment on the top of this blue planet, Yelena knows that the conversation with the guides has completely changed herself these days. It is almost the first time in her life that she realizes how strange it is to give birth to a human being or how unlikely it is to say it in the evening.
"But what human would be so afraid of another intelligent life? Can’t we be friends? " Yelena spit out her doubts.
Xi smiled strangely. "Actually, this issue has always been pessimistic and optimistic. Two pessimists believe that once the intelligent life in the universe meets, it will immediately lead to the looting and killing of the backward party. Now this view has been recognized by many people as the mainstream."
"What about the optimists?" Yelena asked eagerly.
"I am an optimist" looked Yelena in the eye. "This may have something to do with my own astronomy major, but now there is something wrong with my view."
"I don’t love your words." Yelena’s blue eyes were full of curiosity.
"The reason for our optimism is that the universe is huge, and the nearest star to the earth is 4.3 light years away from proxima centauri, but it is a gravitational system, which is very complicated. Through calculation, the Samsung system can find that the big planets can’t be stable, and it is known that all the stars with planets are ten light years away from the earth, but based on the harsh conditions of life generation and evolution, these planetary surfaces just have the possibility of intelligent life. The most powerful telescope on the earth has not received a meaningful signal from these planets for almost a hundred years, which has actually denied the possibility of intelligent life around the earth for dozens of light years."
"How far is it?" Fan Zhe interjected, "The scope of hubble volume is more than 13 billion light years."
"It’s certainly possible to be farther away," Xi said positively. "Although the probability of intelligent life is extremely low, because the universe has a certain number of intelligent life planets, and some of them must far exceed the level of the earth people, then the question comes. If these evolutionary levels may exceed the level of human beings for millions of years, what will alien races do when they come to the earth?"
Yelena and Fan Zhe looked at each other and shook their heads honestly.
"The optimist concludes that they will do nothing, because the so-called human culture on the earth at this stage has no place except a little observation significance, so the super-culture has long understood the secrets of the Ministry of Matter. Maybe when they come to the earth and take a look, they will put out hundreds of stars the size of the sun. How can such a race care about the so-called resources of this grain of sand on the earth?" I often think it’s like that human beings have built a sand that can resist deep-sea pressure. The high-tech submarine came to the Atlantic submarine chimney to observe the tube worms that live on sulfide bacteria. If there are pessimists in the tube worms, they will surely exclaim, Oh, no, man has come to rob us of hydrogen sulfide and delicious sour water. "
Yelena laughed and laughed, and the metaphor made her laugh. Of course, she knew that human fart was full of hydrogen sulfide, but she remembered, "Then why did you say that there was something wrong with your opinion?"
"It’s a wormhole" turned serious. "It’s all because the wormhole is a technology that transcends the times. I think this technology allowed human beings to enter the field before."
"I’m a little confused," Yelena nodded. "This kind of technology may lead to the collision between immature literature and race, which may lead to the pessimists’ foresight."
"No reply yet?" Evening turned to ask Fan Zhe
"I really didn’t receive a reply." Fan Zhe definitely reported that he had inspected the equipment face to face. A qualified engineer believed in his ability. "Hey, wait, there is a signal reply."
Evening and Yelena floated rapidly, and their eyes were locked on the screen.
"This is the pioneer of Bohai Star’s receiving station. Welcome guests from the earth. Resident coordinates are 115 degrees east longitude and 3 degrees north latitude. I repeat, 115 degrees east longitude and 3 degrees north latitude."
"Please instruct the guide when the landing ship is ready." Fan Zhe couldn’t conceal his excitement that he would land on another planet for the first time in his life. What a wonderful situation.
But the evening frowned slightly as if facing a strange thing, and her face was uncertain.
"Fan Zhe left the main ship and Yelena and I landed."
"What?" Fan Zhe asked disappointedly, "I should also go according to the regulations."
"You immediately set up millimeter-scale scanning observation for the whole Bohai Star."
"Plan Reagan doesn’t have this one." Fan Zhe was puzzled.
"This is an order" evening sullen tone no doubt.
(6) Resident.
The station is like a floating pond with huge leaves. The landing cabin is getting closer and closer. The huge leaves are set off like a tiny ladybug. At this time, a narrow gap is lifted on the surface of the station to swallow the landing cabin.
In front of me, there was a shallow hill and grassland, unknown wild flowers blooming brilliantly, and a stream was flowing through a grassland. The ground squirmed with a squirrel, and a few grasshoppers jumped out from the side. The Bohai Star was equivalent to the gravity of the earth. A building flying from all sides stood abruptly on the ground.
A tall man with silver hair and dark skin came out of the room. "Welcome, I am the forerunner Li Gao."
"Hello," Xi nodded faintly. "Can you tell me your pioneer number?"
There was a silence. "Of course, I am the pioneer of Lihaixing, No.42."
"Well, on the 42nd, we’re going to the big ship now," Xi said briefly.
"Not yet, big ship holy land"
"Holy land?" Xi asked doubtfully, "What is that place?"
The tone of the visitors became solemn. "The Holy Land is the most beautiful place in the world."
Evening eye corner glanced at his arm. That button is a transmitter. Everything here has been sent to the wormhole spacecraft. "I want to see this holy place. Please take us there."
The bearer was silent for another second. "Okay, I’ll arrange it. Now please wait for the guide whose resident environment is similar to the earth to know."
Li Gaojin entered the house. Lena just wanted to talk, but it was stopped by the evening. He took out the instrument and scanned it four times to make sure there was no monitoring. After that, he said, "You Ma Lian Fan Zhe asked him to prepare to establish communication with the earth."
"Are you ready now?" Yelena was surprised to ask that the wormhole spacecraft carried a group of twins in the ultra-low temperature environment, in which the quantum communication kept close to absolute degree. They were all twins, one corresponding to the other group left on the earth. The twins were born in a pure energy collision and presented a quantum entanglement state. Because of Pauli’s non-phase principle, their physical state was always the opposite. This is the theory of over-communication, which requires huge energy. Actually, the wormhole spacecraft can support up to two quantum communications. According to the regulations, the first quantum communication should be carried out on the seventh day after landing, and it is necessary to get ready to start up, which really
"I think it is necessary." There is no doubt that "Bohai Star makes me feel uneasy."
Yelena looked around at the beautiful scenery and didn’t know what Xixi meant, but she knew Xixi had carried out the starfish. It must be reasonable to say that what she needed to do was to carry out the orders.
"I also think that the pioneer is a little arrogant." Yelena looked around. "But it’s really no different from the earth. They are so happy to meet us."
"This is stipulated in the articles of association," Xi said coldly. "According to the Promised Land Charter, the pioneers must build a permanent residence of the Earth’s environmental planet government with an area of not less than one square kilometer. Bohai Star has not yet set up a government, and this should be the prototype of the residence."
"I know that the regulations in this charter are very rigid." Yelena has some pie mouth. "For example, the Bohai Sea star in the government residence is a water planet, and it is certainly not easy to maintain a piece of earth’s environment permanently like this."
Xi’s heart swelled with the generosity when he faced the naughty younger generation, but his tone was still indisputable. "The charter is the core of the whole promised land plan. The first rule is that the charter does not violate it or treat it as an enemy of mankind."
