It can be seen that the old man is really happy. However, none of the other members were engaged in astronomy or aerospace, so Academician Zhu's bold remarks failed to stir up enthusiasm in the conference room.

"Ahem, Academician Zhu, I also have a question." Ou Yang hurriedly moved the steps for Academician Zhu and opened his mouth to resolve the embarrassment, "If the existence of the No. 1, No. 2 and No. 3 Earths should be explained by parallel time and space, then may I ask if our Earth is on the same timeline as other Earths?" ”

"Well, my statement may not be accurate, after all, I'm a third-rate, no, amateur sci-fi writer." Ou Yang laughed at himself, he didn't dare to recognize himself as a science fiction writer in front of Academician Zhu, "What I want to ask is, is the time consistent between several earths?" For example, according to the information given in the video, the time when the asteroid hit Earth No. 3 was about 2009 on that Earth, so when the impact occurred, were we in different time and space also in 2009? ”

Ou Yang's expression is still not clear enough, but it is enough for everyone to understand what he means.

Yu Qian glanced at Yang Xiaoqian vaguely, in his world, the living corpse crisis appeared in the thirty-eighth year of Wanli, that is, in 1610 AD, four hundred years later, he crossed from the Star of Hope to this earth, it happened to be 2010, this should not be a coincidence. However, this information has not been made public, and only a very small number of people know about it.

Yang Xiaoqian remained silent, wanting to hear a scientific answer, but unfortunately Academician Zhu shook his head and said: "I'm sorry Xiaoou, I can't answer this question, because I can't give a well-founded judgment, but I personally prefer to keep the timeline consistent, which explains why the equipment summoned by Comrade Tang Tao came from the unattended armory, but there was basically no aging and damage, because the time interval was less than a year." ”

Ou Yang was thoughtful and stopped speaking. Then Qi Xinwu, who had been silent for a long time, opened his mouth, he looked at Yang Xiaoqian and asked, "I think President Yang's idea is very enlightening, but I have a little question, according to President Yang's impromptu numbering, the first disasters that appeared on Earth One, Two and Three were all zombies and mutants, why is this?" Does it mean that different test papers should use the same question as the frontispiece? ”

Before Yang Xiaoqian could speak, Academician Zhu habitually began to answer questions: "This question can be discussed with probability, if there are only three test papers, then this law is contrary to the 'examination theory' put forward by Comrade Xiao Yang, but what if there are thousands or tens of thousands of test papers?" It is not surprising that several copies of the same frontispiece were found. ”

Qi Xinwu nodded, accepted this explanation, and asked, "Yuanjiang has a dome, and the Shuntianfu of Earth No. 2 also has a dome, but why doesn't there be a dome in the small South African city of Earth No. 3?" According to Adrian's diary, there were troops entering the town after the virus outbreak, but both the zombies and mutants had already left the town. This is, first, and second, why have the other two Earth mutants not succeeded in extinct or enslave humans? ”

"Everybody knows how much we pay to deal with mutants. If it weren't for the total surrender of the mutants, we would have suffered heavy losses in the event of a war. Let's not talk about other mutants, just talk about a few innate high-level mutants that we know: Li Jinkui, Shengyi, Wen Yan, and Bai, with their special abilities, they are definitely not something that a few mecha can deal with, even if the Great German Empire on Earth 3 is strong, then what about Earth 2? Even if there is a dome enveloping Shuntianfu, even if there are awakened ones, with the military strength of the Ming Dynasty, can they defeat such a mutant? ”

Director Wei raised a finger and added: "Third, according to the available information, only the area where the disaster occurred will there be awakened people, and according to the historical records of Earth No. 2, the Mingshen Sect gathered a large army outside the Shuntian Mansion and annihilated all the living corpses with the help of the 'Inhumans', this 'Inhumans' must be the Awakened Ones, so where did these Awakened people come from?" ”

The three questions aroused heated discussions, but Yang Xiaoqian was not interested, because similar questions had appeared more than once in his office or in the "brainstorming space" of the special secretary group.

However, speculating without a factual basis is just a waste of time, so Yang Xiaoqian stopped listening attentively and began to think about another question.

Yang Xiaoqian's proposal of the examination theory is not a whim, he has long ago linked disasters of unknown origin to the Fermi paradox, and the 1950 Nobel laureate and physicist Fermi asked a question: an order of magnitude estimate can be estimated that there are about 250 billion stars in the Milky Way, and there are 700 stars (7 x 10^22) in the observable universe - according to statistics, the amount of sand on the earth is about 1/10,000 of this data, in other words, corresponding to every grain of sand on the earth, There should be 10,000 stars in the universe.

There are 5 stars similar to the Sun, so there will be about 10 to 20 Earth-like planets around these stars, and the Earth may not be the most special one compared to them.

That is to say, in the vast universe, there may have been intelligent life millions or even billions of years before the birth of human beings, if they had not all perished, then after such a long period of development, they should have the ability to travel interstellarly, but so far, human beings have not only not seen them, but also not even heard any of the "sounds" they make.

In order to solve the Fermi paradox, people have put forward various theories, one of which is the "big filter theory", which is closely related to Yang Xiaoqian's examination theory.

The Great Filter Theory holds that during the evolution of intelligent life, there will be a wall in front of it, intercepting all biological civilizations from crossing a critical stage.

Yang Xiaoqian's examination theory is a variant of the big filter theory, maybe this wall really exists, and Yang Xiaoqian compares it to a test paper, and the candidates who can't pass the test and are eliminated are all going to destruction, and naturally can't cross the high wall.

It is undoubtedly extremely difficult to pass this test, or to pass this filter, and you have to find another way.

Ou Yang just said a very interesting sentence: "The earth that is moving towards different development paths for various reasons is the candidates with different abilities, some candidates are good at 'physics', some are good at 'chemistry', and some are good at 'biology', and the same test questions are different in difficulty for different candidates." ”

This sentence made Yang Xiaoqian have many associations, and vaguely seemed to find a shortcut.

Although the development direction of the three known Earths is generally the same, there are still differences that cannot be ignored, such as the emergence of the atomic bomb on Earth 3 delayed by 30 years compared to Earth 1, but several generations of combat mechas have been developed, which are ahead of Earth 1 in the ability of the army to maneuver and fight.

Connecting with the visitor from the other world who broke out of the spatial crack after the first magic tide, it is very likely that he also comes from an earth in a different time and space, and according to Yang Xiaoqian's conjecture, that earth may be the origin of rune technology, so it seems that perhaps Tan Brown from the other world comes from an earth with a completely different development direction from this world, and there, rune technology dominates.

If this conjecture comes true, then combined with Ou Yang's words, a crucial clue can be introduced.

Suppose this is a comprehensive test, the test paper is printed with questions from various subjects, including physics, chemistry, biology, humanities and others, and candidates who are good at different subjects can only answer the questions in the field they are familiar with, and it is of course difficult to pass the whole test.

So what's the fastest and easiest way to pass the test?

Of course, it is not to study all the subjects once, the test papers have already been sent, and it is difficult to have enough time to develop in an all-round way, not to mention that from a macro point of view, all-round development is a false proposition.

There is only one reasonable and feasible way to clear the game: cheating.
