Darkness is Coming

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

"Cough, Academician Zhu, I also have a question." Ou Yang hurriedly moved to the steps for Academician Zhu, and opened his mouth to resolve the embarrassment, "If the existence of Earths 1, 2 and 3 should be explained by parallel time and space, then ask us Is this Earth on the same timeline as the other Earths?"

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

  Ou Yang's expression is still not clear enough, but it is enough to make everyone 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, 1610 AD. Four hundred years later, he traveled from the Star of Hope to this earth, which happened to be 2010. Shouldn't be a coincidence. It's just that this information has not been released, and only a very few people know about it.

Yang Xiaoqian kept calm and wanted to hear a scientific answer, but Academician Zhu shook his head and said, "Sorry Xiaoou, I can't answer this question, because I can't give a valid judgment, but I Personally, I tend to say that the time line is consistent, which explains why the equipment summoned by Comrade Tang Tao comes from the unattended armory, but there is basically no aging and damage, because the time interval is less than one year. "

   Ouyang thought about it and stopped talking. 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 inspiring, but I have a little doubt. According to President Yang's impromptu numbering, number one, number two and The first disasters on Earth 3 were zombies and mutants, why is that? Does it mean that different exam papers have the same topic as the frontispiece?"

Before Yang Xiaoqian opened his mouth, Academician Zhu habitually began to answer questions: "This question can be discussed in terms of probability. If there are only three examination papers, then this law is contrary to the 'examination theory' proposed by Comrade Xiao Yang, but if there are How about thousands or tens of thousands of test papers? It’s not surprising to find several papers with the same header.”

Qi Xinwu nodded, accepted the explanation, and asked: "The Yuanjiang River has a dome, and the Shuntian Mansion on Earth 2 also has a dome, but why is there no dome in the small town in South Africa on Earth 3? According to Adrian's diary records, After the outbreak of the virus, an army entered the town, but the zombies and mutants have already left the town. This is one, and two, why have the other two mutants on Earth failed to exterminate or enslave humans?”

"Everyone knows how much we paid in order to deal with the mutants. If the mutants did not surrender in an all-round way, once the war started, we would have suffered heavy losses. Not to mention other mutants, just a few natural high-level mutants we know: Li Jinkui, Shengyi, Wen Yan, and Bai, with their special abilities, are definitely not something that a few mechs can handle. Even if the Great German Empire on Earth 3 is powerful, what about Earth 2? Tianfu, even if there are awakened ones, with the military power of the Ming Dynasty, can they defeat such mutants?"

Director Wei raised a finger and added: "Thirdly, according to the existing information, the Awakened will only appear in the disaster area, and according to the historical records of Earth No. 2, the Ming Shenzong assembled a large army outside Shuntian Mansion, relying on With the help of 'inhumans' to wipe out all the living corpses, these 'inhumans' must be the awakened ones, so where did these awakened ones come from?"

   The three questions aroused heated discussions, but Yang Xiaoqian had little interest, because similar questions had appeared more than once in his office or in the "brainstorming space" of the special secret team.

   But guessing without a factual basis is just a waste of time, so Yang Xiaoqian stopped listening and started thinking about another question.

Yang Xiaoqian's proposal for the examination theory was not a whim. He had linked the catastrophes of unknown origin to the Fermi paradox a long time ago. In 1950, the Nobel Prize winner and physicist Fermi asked a question: making an order of magnitude estimate can infer the Milky Way. There are about 250 billion stars in the observable universe, and there are 700 moi (7x10^22) in the observable universe - according to statistics, the amount of sand on the earth is about one ten thousandth of this data, in other words, corresponding to every A grain of sand, there should be 10,000 stars in the universe.

   There are 5 stars similar to the sun, so among the planets around these stars, there will be about 10 to 20 terrestrial planets. Compared with them, the earth may not be the most special one.

In other words, in the vast universe, there may have been intelligent life millions or even billions of years before the birth of human beings. If they did not all die, then after such a long period of development, they should have had interstellar life. The ability to sail, but so far, humans have not only not seen them, but have not even heard any "sounds" they make.

  In order to answer 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 test theory.

The   Great Filter Theory believes that in the evolution of intelligent life, there will be a wall in front of it, blocking all biological civilizations and preventing them from crossing a critical stage.

Yang Xiaoqian's examination theory is a variant of the big filter theory. Maybe this wall really exists, but Yang Xiaoqian likens it to a test paper. Candidates who fail to pass the test and are eliminated will all be destroyed. Naturally, they will not be able to cross the high wall. .

   In order to pass this test, or to pass this filter, it is undoubtedly extremely difficult, and we must find another way.

Ou Yang said a very interesting thing just now: "The earth, which is going to different development paths for various reasons, is the candidate with different abilities. Some candidates are good at 'physics', some are good at 'chemistry', and some are good at 'biology' ', the same question may have different levels of difficulty for different candidates."

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

Although the development directions of the three known Earths are generally the same, there are still differences that cannot be ignored. For example, the appearance of the atomic bomb on Earth 3 was 30 years later than that on Earth 1, but several generations of combat armors were developed. Leading Earth One in the Army's ability to maneuver operations.

Reconnecting with the alien visitor who broke through the space crack after the first magic tide, it is very likely that he also came 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. In this way, perhaps the outsider Tan Zong came from an earth with a completely different development direction from this world, where rune technology dominates.

   If this conjecture comes true, then combined with what Ouyang said, a crucial clue can be deduced.

Suppose this is a comprehensive test. The test paper is printed with questions from various subjects, including physics, chemistry, biology, humanities and others. Candidates who are good at different subjects can only answer the questions in areas they are familiar with. Passing the entire test is, of course, difficult.

   So what is the fastest and easiest way to pass the test?

   Of course, you don’t have to study all the subjects once. The test papers have been issued, and it is difficult to have enough time to develop in an all-round way. What’s more, from a macro perspective, all-round development is a false proposition.

  There is only one reasonable and feasible way to pass the level: cheating.
