Professor Mei looked at several leaders, then at the peers present, and said in a very firm tone: "I think the cattle slaughter incident was done by extraterrestrial intelligent life, and they slaughtered cattle not to study genes and deal with humans, but for interstellar migration!" ”

"That's, isn't it? Kill a cow and you can be an interstellar immigration? Wei Dongbiao, director of the Bureau of Investigation and Statistics, was the first to stand up against it. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

"Maybe only this idea can be explained!"

"Tell me about the immigration process?" Wang Longqian urged.

"Biochemical immigrants!"

"Biochemical immigrants! You invented it, right? Zhou Zhengtian also felt that what Mei Lin said was a bit fantastical, and couldn't help but mock.

"That's right!" Mei Lin blinked her big smart eyes and smiled at Zhou Zhengtian, as if she had already made a bamboo in the whole cattle slaughtering process. "You're also a physics student, so you should know what is the closest star to Earth?"

"Of course I know, Proxima Centauri is 4.2 light-years away from Earth, which means that even if there are aliens in Centauri, then it will take them 4.2 years to come to Earth in a light-speed spaceship, you don't think it's their immigrants who came to kill cattle and eat them, right?" Zhou Zhengtian smiled more and more disdainfully.

"Maybe, as long as the technology is in place and the thinking is right, any planet may transport life systems to the earth!" Merlin was still unhurried and whetted everyone's appetite.

"According to the known laws of physics, it is true that any civilization once it is created will spread outward. It's just that the speed of electromagnetic signals is the speed of light, but the spaceship is far from that fast, so our first step is to receive their electromagnetic signal, and then we can see the immigrants who come by spaceship! Not to mention that Proxima Centauri does not signal intelligent life, and even if there is, a spaceship at the speed of light cannot carry macroscopic life forms! Zhou Zhengtian said very firmly, and from his serious face, he could feel that the rigor of the laws of physics was unquestionable.

"Huh? Why can't light-speed ships carry macroscopic lifeforms? Wei Dongbiao suddenly became very interested in this topic and couldn't help asking.

"That's right, Director Wei! According to Einstein's theory of relativity, the faster the speed, the greater the mass, and when the particle is accelerated to the speed of light, the mass becomes infinite, and there is no way to continue to accelerate, so the physical particle cannot reach the speed of light at all. Our existing technology can only accelerate microscopic protons and electrons to close to the speed of light, so the payload of high-speed spacecraft is very limited, and the speed of human manned spacecraft is less than 1/10,000th of the speed of light! Zhou Zhengtian used his unique lecture method to explain to Wei Dongbiao in detail.

"That's right, since it is possible to accelerate protons or electrons to the speed of light, it is also possible to accelerate a cell or a virus that carries all the genetic information of intelligent life to close to the speed of light! And when the speed reaches the speed of light, time becomes very slow, the chemical reaction almost stops, and the roots don't need to travel to replenish! Mei Lin interrupted Zhou Zhengtian.

"Even if what you say is true, what's the use of sending a cell or a virus to Earth?" Zhou Zhengtian asked domineeringly.

"After a cell or a virus arrives on the earth, it finds an organic life on the earth as a host, invades the soft parts of the tissue, and then alienates the host body into its own body, such as the eyes and the soft parts of the room! After the invasion, use the nutrients in the host's blood to synthesize your own organism! ”

"According to what you say, the eyes of the cow are gone, not because they have been dug up, but because of the parasitism of alien creatures, the blood is gone, and the parasite synthesizes its own body is exhausted, so isn't there more than a dozen alien creatures who have succeeded in alienation this time?" Professor Wang Tong spun his brain quickly and asked with a sudden epiphany.

"No, they almost all failed!"

"No, they've poked a dozen holes in the cow!" Professor Wang Tong said puzzled.

"The first part of the alienation process of alien creatures is blood, and if the blood cannot continue to decompose other parts of animal tissues after use, the alienation will fail, and in order to prevent the earthlings from obtaining the genes of alien creatures and dealing with them, they have to start the apoptosis process. I guess that the lack of amino acids is a big reason for the failure of alien alienation, and the fact that they can't break down most of the proteins on Earth! Merlin continued to think wildly.

"Apoptosis procedures?" Wang Longqian became more and more puzzled.

"It's the cell that kills itself and then breaks down all the organic matter in the body. If it is carbohydrate or fat decomposition, there is only water and carbon dioxide, which makes the wound that fails to alienate no different from an ordinary wound, but the protein decomposition will produce urea and uric acid, so that the wound will have a urinary smell! ”

"That's right, the wound does smell of urine." Forensic Doctor Zhong nodded in agreement.

"It depends on the test results!" Merlin added.

"But this was only done overnight, and the rate of biochemical reactions is not so fast, right?" Professor Wang Tong expressed doubts.

"If they have a super strong catalyst, it's not impossible to do that!"

"Well, yes, you mean some kind of enzyme, biocatalysts are more efficient?" Wang Tong looked at Mei Lin and asked.

"Not bad!" Merlin replied briefly.

"If the results of the lab can find this enzyme, it will confirm the conjecture." Wang Tong seemed to say to himself.

"The loud noise that the villagers heard that day was the sound of a spaceship carrying a miniature biopropale intruding into the atmosphere, and the white light was the flame that burned when the protective coating on the surface of the spacecraft rubbed against the atmosphere. It seems that when we were investigating that day, the most unreliable young man said that a glowing disc flew by, maybe it was true! Zhou Zhengtian also seemed to have no reason to refute.

"I still have questions, since this alien creature came to Earth to find a host, then it can find any animal, why did it fall in love with the cow?" Forensic doctor Zhong Shenxiu asked.

"This involves the size of the alien creatures, there are three kinds of animals that have been slaughtered: horses, cows, and sheep, and I guess the size of the alien creatures should be a little smaller than the size of the sheep, so that even if a sheep has enough organic matrix for them to alienate an alien creature. And the size of the cow is enough to alienate several of them, so there is a situation where the eyes and the house of the cow are cut off at the same time. Merlin continued to take the doubts in stride.

"No, how do aliens know that there are cows on Earth?" Zhou Zhengtian continued to ask.

"Thanks to you still studying physics, our radio signals for the transmission of film and television have been transmitted for hundreds of light years, and at the beginning it was mainly a sound and distress signal, and then there were no images. Since aliens can travel through the stars, it shouldn't be difficult to build a TV, so those extraterrestrial scientists will definitely be very excited when they see the image of a cow on their screen, wow, ideal parasitic carrier! Merlin's peculiar humor made everyone laugh.

"That's right, maybe they know about the domestic animals of this planet through our own recorded videos, but since they can find horses, cattle and sheep as hosts, they can naturally find pigs or dogs as hosts, but we have never heard of pig slaughter or dog slaughter! I haven't heard of the slaughter of wild animals either! Zhou Zhengtian still thinks this idea is mysterious.

"I think aliens have brains better than you!" Merlin was a little impatient when asked, "Even in the images we send to outer space, dogs and pigs are relatively close to people, and it is difficult to use their hands, and their alienation process takes a certain amount of time, so try to avoid human eyes and ears." As for wild animals, they didn't appear on the screen in the early days, and although they appeared later, the probability was still relatively low, so the aliens chose horses, cows and sheep in order to ensure the success rate, understand, Professor Zhou! ”

Although this idea can explain a lot of problems, but the problem of motivation has not been solved. Aliens transport a few individuals who may not be successful in alienation to Earth, and even if the alienation is successful, it may be difficult to get rid of the fate of being slaughtered by others, so why should they bother, why should they come all the way to a strange place to kill themselves? Feng Wenjing suddenly felt that something was wrong.

"In fact, in the genetic material of the organism, there are very few that can play a role, if the task information is stored in those sequences that do not have a gene expression effect, once the alienation is successful, the information can be extracted from it to complete the task!"

"Haha, Professor Mei is so talented, so what do you say the aliens look like?" Wei Dongbiao also showed strong interest and said half-sarcastically.

"I think aliens should be about the same as humans, with two arms, two legs, two eyes, and two ears..."

"Haha, just make it up!" Wang Longqian couldn't help but laugh.

"Director Wang, I didn't make this up, it's well-documented!"

"What does this alien look like? So why can't aliens grow three legs? ”

"You're a layman, you know, all the laws of physics are symmetrical, right, Professor Zhou?"

Professor Zhou saw that everyone was looking at him, so he had no choice but to speak: "Director Wang, what she said is right, except for the non-conservation of cosmic symmetry under weak interaction proposed by Yang Zhenning and Li Zhengdao, all other physical laws are strictly symmetrical!" ”

"Okay, then this problem is solved, then why can't it be four legs, isn't the four symmetrical? Some animals just have a lot of legs! Wang Longqian asked.

"Yes, the four are also symmetrical, but God tends to simplify all creations, which is why many great scientists convert to religion when they study science to the depths! The four-legged ones are still trying to evolve, the intelligent life on the earth, one head is for the unification of government decrees, two arms are for one auxiliary and one master, two eyes are for judging the distance of objects, two ears are for hearing stereo sound, all creatures that cannot accurately capture various information in the environment and take coping strategies have been eliminated in the process of evolution! And that's not all, on a global scale, the direction of evolution of all species is surprisingly consistent! With so many coincidences, does Director Wang still think I'm making it up? Mei Lin asked Wang Longqian very confidently.

"Ha, what you said also has some truth!" Wang Longqian smiled embarrassedly.

"It's not just a little reasonable, I think it won't be long before a monster will appear in the town where the cattle slaughter incident occurred, weighing about thirty kilograms, and sucking blood for a living!" The more Merlin spoke, the more smug he became.

"Didn't you say that none of those alien creatures were successful in alienation?" Wang Longqian asked in surprise.

"I mean, almost all of them failed, but there was still one alienation that succeeded!"

"You mean the half-body cow?" Zhong Shenxiu asked.

"Hmm," Merlin nodded smugly.

"Nonsense!" Just when Mei Lin was complacent about her wit, Mo Shoucheng's face became very ugly, and suddenly he stood up and pointed at the experts present with his rather dexterous finger and asked, "Is this how you do it scientifically?" Yes? I really don't know how you got your professorship? Director Mo Shoucheng seemed to be angrier than the slaughtered cattle, and for a moment the air in the conference room froze, and everyone stopped talking.

A phone ringing broke the silence of the conference room, Professor Wang Tong quickly took out the phone and looked at it, he signaled to everyone and went out with the phone, everyone continued to bow their heads and be silent. After a while, Professor Wang returned: "The test results are out, supporting Professor Mei's conjecture!" Professor Wang calmed down his nervousness and said.

"What do you say? What does it mean to support Professor May's conjecture? Wang Longqian seems to see the dawn of solving the problem.

"The experimenter first tested the radioactivity of the wound, and there was nothing abnormal, and it was certainly not hit by a comet meteorite. They found a special protein in the tissues near the wound, which should be the kind of high-performance protein that Professor Mei said, but unfortunately it was inactive. In further experiments, the experimenters found more than 20 amino acids in this protein, including the amino acid found in the Murchison meteorite! ”

"What do you say? Found amino acids in the Murchison meteorite? Professor Merlin screamed excitedly.

"Yes, they're reaching out to the Australian scientific community to try to get their hands on the original material!"

"Ah, that's great! Yes! Merlin clenched her fists in celebration.

"What does the Murchison meteorite mean? What about that amino acid? Wang Longqian looked at Mei Lin's madness for no reason, and was a little dazed.

Wang Tong hurriedly explained: "That's the case, Director Wang! The Murchison meteorite is a special meteorite that landed in the town of Enlightenment, Australia in September 1969, and researchers found DNA and amino acids on this meteorite, and these amino acids did not come from Earth! ”

"Does this have anything to do with the cattle slaughter we studied?" Wei Dongbiao also asked puzzled.

"Yes," Wang Tong nodded. "In terms of chemical composition, the Murchison meteorite is a rare space rock, and less than 5% of the total number of carbonaceous chondrites found on Earth has been discovered, NASA says that the organic matter molecules in space rocks are usually very small, only a few parts per 10,000 to a few parts per billion. The discovery of DNA and amino acids is even rarer, because DNA is the genetic material of most organisms on Earth, and amino acids are the basic units that make up proteins, which in turn are the main bearers of life activities, and many scientists speculate that there may be some kind of life form in meteorites! ”

"Yes, now that we have found this amino acid at the scene of the cattle slaughter, it is very likely that the culprit of the cattle slaughter and the Murchison meteorite are from the same planet!" Merlin said excitedly. "So a new era is coming!"

"Just now, Professor Mei said that the reason for the failure of alienation is that the types of amino acids are not enough, and it has also been verified! It's just that I don't understand, there is a lack of amino acids, why is there still a successful alienation? Wang Tong's gaze turned to Mei Lin.

Mei Lin calmed down a little, and suddenly felt a sense of relief: "I have already asked them at the scene, and the person concerned said that there is a problem with the liver of the cow, and I estimate that there is a genetic mutation that can synthesize new amino acids, which ensures the success of the alien organism!" ”

"The experimenters also found that the tissues near the wound were permeated with different degrees of urea, which they estimated to be the result of autophagy, which is also consistent with Professor Mei's conjecture!" Wang Tong added.

"Then the vampire monster she predicted just now is also possible?" Wang Longqian asked vigilantly.

"It should be, it should be!" Professor Wang Tong replied hesitantly.

"Then we will draft a report according to Professor Mei's point of view, and then notify the higher authorities to let them take preventive measures as soon as possible!"

"No way!" After a brief silence just now, Mo Shoucheng couldn't wait to come out and intervene. "The higher authorities asked us to find out the truth of the matter in order to eliminate the panic of the people, but now it is good, not only has the panic not been eliminated, but there has been a situation that has made the people panic, so the results of our efforts to maintain stability have been wasted! I will not allow you to do that! ”

"Director, I'm afraid this is the truth of the matter, why can't it be passed?" Wang Lung is arguing with words.

"That's not good, it's not in the interests of the country that you do this, the country wants to be stable, the people want to live and work in peace and contentment, have you considered what the consequences will be once this news is announced? Society will be in turmoil! Mo Shoucheng said in an irrefutable tone.

"So what do you say?" Wang Longqian had no choice but to throw this problem back to Mo Shoucheng.

"Didn't you just come up with a lot of conjectures? Just find the closest to the facts and report the findings! ”

"So which one do you think is better?" Wang Longqian reluctantly turned to the professors.

"It's not the first time, I'm so inexperienced, let's see how other countries deal with it!" Mo Shoucheng put down the cigarette butt and reminded from the side.

"Ha" Wang Lung let out a sigh of relief. "See, to follow the FBI's point of view, the cattle slaughter was done by carnivores or scavengers. Professor May! According to the instructions of the director, write an investigation report, and sign it after the experts confirm that it is correct! ”

"Okay!" Merlin said listlessly, not as radiant as she had just stated her conjecture.

"Make the report as soon as possible, the pressure of public opinion from the higher authorities is also very high, and we need to hold a press conference based on the report as soon as possible!" Mo Shoucheng admonished. "Thank you all for your hard work, let's be here today!" After saying that, he got up and left, a few professors, you look at me, I see that you have nothing to do, and walked out of the conference room in a daze.
