"These are just basic knowledge, and you can know it after a little self-study." Zhang Heng entered keywords while talking. He used the combination of aliens + Cretaceous at the beginning, but the things he found were all strange. Know where the roadside stand news pops up.
Such as "The Shocking Truth: Dinosaurs were Killed by Aliens!" ", but this time the shock department may be rare for a blind cat to encounter a dead mouse. After so many nonsense, it finally came true. In addition, there is "Evidence that Aliens Have Visited the Earth Already!" " and "The Chinese are the ancestors of aliens, 11 major proofs! "This kind of inexplicable thing makes people look at the question mark.
So Zhang Heng recalled Lin Sisi's weekly diary again, changed the keyword combination, and searched with alien + disaster + block. At the same time, in order to prevent someone from directly deleting information in the database, he also set up a ladder to climb over the wall. , although google has withdrawn from the mainland, the crawlers of google search are still tirelessly grabbing the information of websites, which can just complement Baidu's snapshots.
This time, I found some worthwhile posts. Zhang Heng simply turned on two computers and spent ten minutes reading them with Bai Qing. However, the only post that matched the content was only one The short horror sci-fi story conceived by the author, the post was not deleted, but he posted it on the Internet with great interest, but there were very few respondents below, and the only few who left comments were basically criticisms.
- I don't think so.
— It can’t be said that way, maybe the author himself was replaced by aliens, which is why the writing is so bad.
— Makes sense, so everything makes sense.
...
Bai Qing couldn't stand it anymore, and replied below.
—Actually, the idea is pretty good, it will be even better if you modify it, come on!
However, the original author was probably hit too hard, and the login time was still displayed three weeks ago, and he didn't seem to have visited the forum since then.
But Zhang Heng noticed the last message, it was a day ago, the id was called Voyager 1, it was just a nonsensical sentence.
— Are you a Fermi Paradox? So the previous set of things was only used to write science fiction
Zhang Heng glanced at the id and found that the other party was online.
So I sent him a private message.
—Can you tell us about the Fermi Paradox
Voyager 1 replied
-Hold on.
It took about two minutes for him to send a second message.
— Just now the boss was walking around outside, and he couldn’t let him find out about my fishing at work. If you want to know about Fermi’s paradox, wouldn’t it be enough to just go to Baidu directly on the Internet
— No, there was a sci-fi article before, and you left a comment below.
—Oh oh oh, you said that, you probably recognized the wrong person. That guy is not from this forum, but an ID from the previous Douban City group. He is a very mysterious guy who only logs in from 5:30 to 6:00 every day. You will never see him before 5:30 or after 6:00. Punctual like a robot.
Zhang Hengmoran, if this id is really Lin Sisi, this situation probably happened because Lin Sisi's parents restricted her online time, and many families with young children would have similar regulations. Unexpectedly, this made Fermi Paradoxes become terribly mysterious in the group.
—Do you know her well
Zhang Heng asked.
-she? Is the Fermi Paradox female? Speaking of it, she seems to have never said that she is a man or a woman. I don’t know her too well. After all, her activity time is just when most people are off work, and she is very serious. Arguing with you, until you surrender, or until she goes offline at some point, but her level is quite good, and some people have doubted whether she is a teacher of some research institute or school before.
-oh
—By the way, the group also organized an offline stargazing activity before. Fermi Paradox asked a lot, saying that I and two friends would come, but later said that my family disagreed and I couldn’t come. Yes, that’s it. At that time, we speculated that he was a man, he should have been married, and his wife was stricter.
Zhang Heng and Bai Qing exchanged glances, it seems that they should have found the right person this time, and Zhang Heng continued typing.
—What was that set of things you mentioned earlier
—Oh, didn’t the “Three-Body Problem” win an award last year, so the topic of communicating with aliens has become very popular recently, and I remember that about three weeks ago, the Fermi Paradox also posted a post saying that she A segment of radio emissions from space was deciphered.
-Um
Voyager 1 is very patient, of course, it may be idle, and he explained it by the way.
——The so-called radio is actually a kind of electromagnetic radiation, but it can penetrate the interstellar matter and bring galaxies information at a farther distance. Scientists use radio telescopes to observe and study radio waves. Before that, the world's largest radio telescope was in Puerto Rico, named The Arecibo radio telescope has a diameter of 350 meters, but the fast radio telescope with a diameter of 500 meters in our country should be completed in the second half of this year, and it should be the largest radio telescope in the world by then.
Voyager 1 said proudly.
—I know what a radio telescope is.
Zhang Hengdao.
—Actually, I want to know how the Fermi paradox is deciphered by radio radiation.
- Wait a minute.
The enthusiastic Traveler No. 1 boarded Douban immediately after speaking, but two minutes later, he let out a cry of surprise.
—Why is that post gone
— What is the title
Zhang Heng asked.
——It is called "I deciphered a piece of radio radiation". The Fermi paradox said that she found that a piece of radio radiation contained important information, but no one in the group believed it at that time, because radio is generally emitted by celestial bodies, and there is no such thing as What is the actual meaning? Of course, its essence is a kind of electromagnetic radiation, which can be used to store information in theory, but it is hard to imagine that there are alien life that can transform a pulsar into a radio transmitter or the like At that time, everyone thought she was joking or something, and this time she did not refute it for the first time, and the matter passed like this.
Zhang Heng heard that he searched the title of the post, but found that the information downloaded by Baidu spider or Google crawler had also been deleted. Zhang Heng remembered the guy who could modify the surveillance video that he met before. There were obviously computers among those things. master.
"What should I do now?" Bai Qing asked, this feeling is very bad, obviously he has found the right direction, and he is only one step away from the final answer, but he is stuck in this final link.
As a result, before Zhang Heng could speak, he saw another message from Voyager 1 on the other side.
—Well, it doesn’t really matter, it’s gone if it’s gone, anyway, I’ve already learned her deciphering method, but it seems to be only useful for the radio radiation she emitted. After that, I searched all the radio radiation I could find on the Internet There is no record about her, no matter how you look at it, she probably made it up by herself.
