A map of the world is projected by a projector onto a giant screen behind Zhang Dada, on which three locations are highlighted.

One in the polar regions, one in the South Pacific, and one in the desert.

Next to the map, several images of alien text appeared, and the images were clearly visible, looking like a swarm of insects flying.

"In Houston, Dr. George Mather also used these words as the 'opening room' of the conference, and I saw them again here today, and I was looking forward to what they were saying." A foreign researcher said as he stood up after raising his hand to get permission.

"What they tell is the world we live in," Zhang Dada said with a smile, "I have marked the content of these alien characters on this world map, please take a look." ”

Zhang Dada said and pointed to the three locations marked on the map with the laser pointer in his hand, "These coordinates are the content corresponding to these alien characters next to it, and I cracked them." ”

Zhang Dada reported three detailed latitude and longitude coordinates, and someone in the audience began to record them with equipment or pen and paper, only a silver-haired middle-aged man frowned slightly, combined with the situation of the submarine he commanded tracking the Huaguo scientific research ship "Snow Dragon" a few months ago, this man seemed to have guessed something.

"Is there anything special about these three places? Kindness...... It seems that they are all places where no one goes. Someone in the audience raised their hand and asked.

"If I want to say anything special, I really don't. But the information contained in these alien words is not only coordinates," Zhang Dada pressed the projection remote control in his other hand, and the time numbers corresponding to the three coordinates instantly jumped on the screen.

"God, 800,000 years ago?" Someone saw one of these moments and exclaimed quietly.

"Is this coordinate the Pyramid of Khufu? I've been there, but what happened in 2690 B.C.? ”

"Spitsbergen, Doomsday Seed Bank? November 7, 2010? ”

In the venue, everyone was talking about the time that was suddenly projected on the screen, and at this time, Zhang Dada raised his hand and pressed it down, signaling everyone to keep quiet.

"Ladies and gentlemen, all the data I want to disclose is on this, the time, and the corresponding place, please remember these data, because they are the results of my decipherment of alien scripts."

"It's not a lot of information, but it has opened a door for us, and if we want to know what's behind the door, we need to go inside the door and look for it."

"Professor Zhang, what do you mean by going through the door to find it?" After raising his hand, he stood up and asked a question about a Jepsy expert.

"What does it mean that some of these alien texts that Dr. George Mather has released have been deciphered to deduce these times and coordinates? I think it shows that these coordinates corresponding to time are not just coordinates. ”

"Pure coordinates?" Martin asked.

"Yes, allow me to describe it that way. It seems to me that there is some kind of connection between them and extraterrestrial civilizations, and these connections are exactly what I just talked about behind that gate. Zhang Dada paused when he said this, and continued, "These need to be further explored. ”

"Professor Zhang, do you mean to tell everyone that we are going to go to these places?" The silver-haired middle-aged man who had frowned slightly stood up and asked, his tone seemed to have something pointed, but Zhang Dada didn't seem to pay much attention.

"What do you call Your Excellency?" Zhang Dada asked.

"Daniel Frederick, serving in the U.S. Naval Operations Department," the silver-haired man had the aura of a soldier all over his body, his eyes shining, waiting for Zhang Dada's answer.

"Looks like a general," Zhang Dada smiled and politely motioned for him to be seated. "Your Excellency is really discerning, and you can get to the bottom of it with one word. Since the aliens have written about these places, it means that these places have attracted their attention, and they ...... Well...... I think something happened there. ”

"Look," Zhang Dada said, switching the image projected on the giant screen to another one, "Lemuria, I wonder if any of you have studied it?" ”

A bearded scholar raised his hand to speak, and Zhang nodded at him.

"I'm Navazu Sidi from Xindu, hello everyone," Navazu said, standing up and bowing to the other attendees, "I majored in archaeology, and as far as I know, Lemuria is a legendary civilization that sank into the sea in ancient times. Lemuria and the legendary continent of Atlantis in ancient Egypt and the continent of Mu in the Pacific Ocean in Mayan legends are equivalent to the disappeared civilization, some say that Lemuria is Atlantis or Mu, and some people say that Lemuria and Atlantis were two major civilizations that coexisted in the same period. ”

"I have seen in Madagascar what appears to be a cross between a chinchilla and an ape, and their name is 'remer', and I have found traces of their life in Africa, the Malay Peninsula and my homeland, so I speculate that there is a land bridge between Madagascar and my homeland, which existed until the Cenozoic, that is, the age of mammals. In previous research reports, I concluded that Lemuria was the birthplace of human civilization. ”

"If you are interested, I can recommend you to read Mr. Louis Spence's book The Lemurian Question, and I am done."

Zhang Dada took the lead and applauded, "Thank you, Dr. Navazu, for the explanation. ”

He continued, "Lemuria does have too many mysteries as a prehistoric civilization, and it is the most mysterious of the three coordinates, and it is now hidden in the deep sea. The other two coordinates are the Pyramid of Khufu on the outskirts of Cairo, Egypt, and the Doomsday Seed Bank in Longyearbyen, Spitsbergen Island, both of which we've visited. ”

Seeing the buzzing exchange sound from the audience, Zhang Dada looked around at the expressions of everyone in the audience, "You must be very curious about what we found in these two places, I want to say that it's a pity that we didn't find anything." ”

"It's really nothing," Zhang Dada emphasized again.

"Professor, if nothing is found, doesn't that mean that the deciphered information has no value?"

"In the previous trip to the polar regions and deserts, we made a mistake, we ignored the time," Zhang Dada said, "In the deciphered information, each coordinate corresponds to a separate time, and our exploration only met part of the conditions, and it is reasonable to return in vain." ”

"Could it be that if you mean to go to those places, you have to match the time?"

"I'm afraid so," Zhang Dada nodded.

"But...... Those are all past time, isn't it a false proposition to go back to the past? Someone in the audience asked.

"As far as I know, there are countries that have been doing research on time and space for decades." Zhang Dada thought for a moment and continued, "Knowledge about this is not my forte, so I can't reveal its principle here, but it is enough for you to know that we humans can travel through time. ”

"I don't know if you've heard of the 'grandfather paradox,'" someone in the audience questioned.

"No, I'd like to hear about it," Zhang Dada motioned for him to continue.

"The 'grandfather paradox' is a kind of time-travel paradox, if you go back in time and kill your grandfather before your father was born, this action creates an unexplained contradiction: you go back in time and kill your young grandfather, and when your grandfather dies there is no father, and without your father there would be no you, so who killed your grandfather? Or to put it another way, your presence means that your grandfather didn't die because of you, so why did you kill him? ”

"Well......," Zhang Dada is proficient in linguistics, and the "paradox" proposed by others just now stumped him.

"Parallel universes." The person who stood up to relieve Zhang Dada was Zhao Kang, and as soon as he spoke, he found that everyone's eyes were focused on him, and he couldn't help but feel a little nervous.

"Since you mentioned parallel worlds, it seems that you have a lot of research in quantum mechanics and theoretical astronomy, and I would love to hear your thoughts."

"I understand a little," Zhao Kang replied modestly in the face of others' doubts, "In my personal understanding, parallel universes refer to other universes that are separated from a certain universe and exist parallel to the original universe, which are both similar and different. It's like if I write a program that can freely simulate and create a series of scenarios and continue to derive them, and when I artificially make small changes in the process of deriving it, it will cause the next result to be inconsistent with the result that I didn't change, and it changes. This situation can be compared to the 'grandfather paradox' that someone just mentioned, my explanation is that if you go back in time and kill your grandfather before he was born, you only kill your grandfather in a parallel universe, and there are countless parallel universes like this, and in this parallel universe where you kill your grandfather, your father will not be born, and you will naturally not exist in the future. You don't belong to that parallel universe, so there's no such thing as a 'paradox'. “

Zhao Kang saw that everyone was reminiscing about what he had just said, and he continued to explain, "Let me use a simple analogy, parallel universes may be in the same space system, but their time systems are different, this is like two trains speeding on the same railway line, they have first and last, they may be in the same time system, but the space system is different, and the same is true for cars driving in the upper and lower passages of the overpass at the same time. ”
