It seemed that at the same time, another voice in everyone's head disappeared. Before disappearing, the voice said goodbye to everyone, and said to the ship, "Good luck, human." ”

The crowd has not yet recovered from this message. All of the serving personnel received a message from the captain: "Please assemble in the conference room. ”

In the conference room, most of the crowds of decision-making bodies on the Explorer had arrived. Everyone was talking to each other about the information that had just appeared in their minds. Nanjia, as the little assistant of this meeting, her main task is also to ask each crew member about the information they received from that letter.

"Okay, thank you, do you remember that lifeform AI told you anything else?" Nanjia said to one of the crew members.

"It's probably what I told you, nothing else, maybe everyone is curious about the same questions." The crew replied.

"Okay, if you remember anything special, just let me know and I'll add to it." After Nanjia finished speaking, he said to the smart bracelet: "Pause the recording." Then she looked at the next crew member, who was her teacher, Qi Ming.

"Teacher, tell me about your version, everyone's version is very different, maybe your version is unique."

"I think everyone already knows where he came from. And he must also say that he is an explorer in the universe. Is that right? ”

"Yes, everyone said he was from the Pillar of Creation. Moreover, he is an explorer in the universe, as if he wants to discover more civilizations, and then unite different civilizations to explore the meaning of this universe. Nanjia replied.

"Well, after I talked to him, he said that he has been wandering in the universe for more than 5,000 years, and he has met very few lives, but the lives he has encountered are ever-changing." Qi Ming replied.

"Why don't I have this information, is it because of the knowledge stored in our heads?"

"Well, I think he also told you that this letter he left behind can read your memories and then simulate the same language to communicate with you, and naturally knows every corner of your life. It may be aimed at different groups of people and with different messages being expressed. You see. After speaking, Qi Ming pressed the button on the bracelet, and then tinkered a few times to call up Nanjia's record information about the incident. Later, he continued:

"Nanjia, in your subconscious, you definitely want to return to Earth. In other words, when he talks to you, he specifically gets information about the mustache. ”

"Yes, but I also want to see what the distant land is like. But I'm more concerned about how to find him. ”

"So, when he talked to you, he made a specific request for rescue, such as the need to be within 200 years, otherwise many unexpected factors may cause him to stay away from that coordinate a long time ago."

"And you, teacher, can you tell me about civilization?"

"Back in the early days of their civilization, there was a sociologist like Robin Hansen."

"Is it the scientist who proposed the Great Screening Theory?"

"Yes, Nanjia, you remember right. Their society has found that the planets where intelligent life exists may not exist, because of the various accidents in the universe that can give birth to the conditions for life. But there is also another unique group of scientists who believe that this theory exists because we have not discovered extraterrestrial life, and once it is discovered, then the theory will be self-defeating. It's as if we now know this universe and we're not alone. ”

"And what about later? Did their civilization start the Age of Discovery? ”

"Yes, so in their eyes, we are like them when they are younger. From proposing a theory, and then denying themselves through practice, and then discovering in practice how ridiculous they thought and knew in the early days of civilization. ”

Qi Ming picked up the water cup on the side, took a sip, and then said to Nan Jia:

"Practice is the only criterion for testing truth, and this kind of thinking can be said to permeate the entire universe. Then their civilization began to be like us, and the Age of Exploration began. Although they may have found only a handful of life in thousands of years, the many different life forms and different social cultures have made them feel that this universe is truly wonderful. They have seen the life that has just evolved from primitive animals to intelligent life, and they have also seen the life that is in the era of the civilization of the home planet, and they have also seen the civilization that has just set off from the civilization of the home planet and will step out of the universe, and we are the first time they have encountered intelligent beings who can go so far. ”

"That's why he left this letter?"

"Well, it's not just a letter, it's an invitation. When we have the ability to reach their home galaxy, the Pillar of Creation, meet their society, and use this hexagonal as a proof to explore the mysteries of this universe with them. ”

"It's a pity that with our technology, when we can get there, maybe the humans are long gone." Nanjia responded.

"No, maybe they're gone, but he said that the search for the unknown in this universe is eternal. Maybe the day we arrive, we will still receive the message they left behind, and their technology will help us better discover the universe. ”

"How long will they live? Look at this explorer who has been adrift in the universe for at least thousands of years, why can he live for so long? Aren't they carbon-based life or are they a mechanical civilization? ”

"I don't know about that, maybe one day when we find them, we'll find out what kind of species they are."

Nan Jia then asked Qi Ming:

"Did he tell you how to use this communication technology?"

"I did ask for information about this, but it's a pity. He said that it may be a long, long time for us humans to understand this communication technology, or forever. Because light went from theory to practice for more than a thousand years. ”

"More than a thousand years, oh my God. For us, it took us more than a decade to increase human life expectancy to 200 years, so that technology may be astronomical. Did he say anything about how to increase the speed of the ship? ”

"No, and for me, maybe I like history and culture more, and he is more suitable for me to exchange history about their exploration of the universe. By the way, they have also experienced many, many times of social speculation, and they also believe that when a civilization is highly developed, there will eventually be a collision of hedonism and realism. ”

"This is what you call a brain in a jar, and the idea of exploring distant places. I seem to remember someone telling me. Nanjia responded.

"Yes, their civilization even went to war because of it, but in the end the theorists triumphed over the hedonists. As a result, the entire civilization has vigorously developed science and technology with the power of the whole world, and interstellar travel has become possible. ”

"Fortunately, we are human sane, human beings have eliminated disputes as early as the 22nd century, and the theory of a community with a shared future for mankind has made everyone hug each other tightly."

Qi Ming's eyes suddenly flashed with light, and he continued: "Well, that's true, if it weren't for the sages who put forward these theories, then we human beings may still be fighting and fighting again, thus burying ourselves with our own hands. ”
