"Research? What do you mean? ”

Petra was puzzled by Yang Yi's question, and Yang Yi said indifferently: "Of course, it refers to the aspect you are interested in, I am not very interested in the financial industry, and you are not too interested in this aspect, so why not discuss what we like." ”

Yang Yi and Petra met for a purpose, but the excuse for his first acquaintance with Petra was their common interests.

Sure enough, Petra was interested.

"If you talk about amateur research, no, it should be a hobby, in fact, it's not research, you know, since you last showed you those interesting Soviet archives, I've been more interested in what's behind the moon."

Petra sat up, and she said with interest, "Do you think there is any connection between humans and aliens on Earth?" ”

"Well, that's not my focus, so I might as well let you tell me about it."

Petra nodded repeatedly, and then she said with interest: "I've been thinking about a question, that is, are humans lonely?" Or is the intelligent species solitary? Thinking rationally, we should not be alone, because the universe is too big, even if the birth of human beings, no, even if the birth of life on the whole earth is an accident of chance, but it is still too arrogant to conclude that there is no other intelligent life in the universe, don't you think? ”

"Yes, I feel the same way."

"Then there is a question, if there are other intelligent beings in the universe, even intelligent civilizations, will they come to the earth? The sign of an intelligent life is the curiosity of the universe, curiosity will definitely explore, in ancient times human beings began to have endless curiosity and desire to explore the starry sky, so can it be considered that as long as a civilization is formed, it will definitely explore the universe, because the exploration of the unknown is absolutely the common nature of civilization. ”

"Yes, agreed."

"Human civilization has only been born for more than 5,000 years, and I mean civilization and not the existence time of the human species, which is extremely important to understand, and then, in the more than 5,000 years since the beginning of human civilization, we have too many records of suspected but unverifiable contact with extraterrestrial civilizations, but as I said, we only have suspected cases, but we can't confirm any of them, right?"

Yang Yi thought for a while and said, "You are the Fermi paradox. ”

Petra nodded repeatedly, she looked excited.

The reason why the conversation between smart people, or between like-minded people, is so pleasant, is because they have a common language, and what one person says will understand and understand.

The Fermi paradox was proposed by the Nobel laureate and physicist Fermi.

The simplest way to explain the Fermi paradox is only two sentences, first, scientific inference can prove that aliens exist, and the universe has an almost infinite time to tug, and aliens can evolve much earlier than humans, then aliens should have been to Earth, or even exist somewhere on Earth.

Aliens do not exist because humans have not found any evidence of their existence.

Petra's doubts can be summed up in two sentences of Fermi's paradox.

"So what if we can confirm that humans on Earth have been in contact with extraterrestrial civilizations for a long time?"

Petra asked Yang Yi this sentence with excitement on her face, and then she became very serious and said: "Now, there are too many UFO sighting records in the world, and there are countless of them, and there are many that can be explained afterwards, but there are also many that cannot be explained. ”

Yang Yi felt interesting, he nodded and said, "Yes, you continue." ”

Petra raised her hands and said, "Is there such a possibility that the government has joined forces to block the news, and if the government of various countries consciously does not let the people obtain this news?" ”

"Uh......"

"You're familiar with spies, so do you agree with that?"

Yang Yi smiled bitterly and said, "Yes, this is a fact. ”

Petra became very serious and said: "I'm a conspiracy theorist, my focus on the third type of contact has been since I was very young, and I will also think about one thing, why did human civilization suddenly appear and suddenly become so developed, the theory of evolution can explain the slow evolution of species, but the explosion of human civilization in the primitive era, can you believe this?" ”

Yang Yi spread his hands, he wanted to hear what research Petra was doing, but he didn't want to discuss the research of alien civilizations with Petra.

Petra exhaled and said, "I was thinking, if the current Zhengfu will block the news, what about the ancient times?" For example, the pyramids of Egypt, in terms of productivity and technology at that time, the existence of the pyramids itself is incredible. ”

"Uh, yes."

Petra laughed, and then she said proudly, "So I funded a website dedicated to searching for clues about the connection between extraterrestrial civilizations and Earth, and most of the members of this website are amateurs doing this, but we have a great time working together." ”

Yang Yi's heart began to pound, and then he coughed lightly and said, "What did you find?" ”

"Well, I'd love to put the top-secret file you gave me online, but you don't agree......"

Petra looked helpless.

Yang Yi said with an indifferent face: "Before you read the Soviet archives, did you have any achievements, of course, you can also have any achievements now, you know that I am very interested in these, so I want to hear it." ”

Petra thought for a moment and said, "Well, there are still some of them, but they can't be called gains, just some clues, oh no, it's frustrating that there are no breakthroughs at all, everything is a rehash of the same old tune, such as the construction of pyramids, such as the pyramid types of the Mayans, we tried to find out the written records of contact with aliens, but it seems that someone is deliberately erasing these records, I suspect it's Zhengfu, uh, there is no big progress, in fact, once we thought we had found a breakthrough, but it's a pity." ”

"What's the pity?"

"Well, an amateur history buff, especially interested in studying the history of the Crusades in Europe, he made an interesting argument, that is, the Cabinet of Saints and the Knights Templar, he thought that the Knights Templar really got something when they were stationed in the Holy City, and this thing was the Ark, and he thought that the Ark contained not the Ten Commandments, nor a weapon, but some kind of medical item with the effect of resurrecting the dead, like a medical warehouse, and this history buff seems to have really found some evidence, But it's a pity that he died, and all research was interrupted. ”

Yang Yi tried his best to appear calm, and then he smiled: "Very interesting argument, but unfortunately too lacking in support." ”
