"These are just the basics, and you can learn a little bit on your own." Zhang Heng entered the keyword as he spoke, the combination of aliens + Cretaceous that he used at the beginning, but the things he searched for were all roadside stall news that appeared out of nowhere.

Such as "The Terrible Truth: Dinosaurs Were Killed by Aliens!" But this time the shock department may have a rare blind cat meeting a dead mouse, and Hu Xu has finally fulfilled it once so many times, and there is also "Evidence that aliens have already visited the earth!" and "Chinese are the ancestors of aliens, 11 ironclad proofs!" This kind of inexplicable thing makes people look at a question mark.

So Zhang Heng recalled Lin Sisi's weekly diary again, changed the group of keyword combinations, and used aliens + disasters + blocking to do search, and at the same time in order to prevent someone from directly deleting information in the database, by the way, he also set up a ladder to climb over the wall, although Google has withdrawn from the mainland, but the crawler of Google search is still tirelessly crawling the information of the Chinese website, which can be complementary to Baidu snapshot.

This time, I searched out some posts worth seeing, Zhang Heng simply turned on two computers, and spent ten minutes with Bai Qing to read those posts, but the only post that can match the content is just a short horror science fiction story conceived by the author, and the post was not deleted, but he posted it on the Internet with great interest, but there were few responders below, and the only few messages were basically criticism-based.

- I don't think so.

- I can't say that, maybe the author himself was replaced by aliens, which is why he wrote so badly.

- Makes sense, so that everything makes sense.

…………

Bai Qing couldn't stand it a little, and replied below.

- Actually, the idea is quite good, and it will be even better if you revise it, come on!

However, the original author was probably hit too hard, and the login time was still displayed three weeks ago, and it seems that he hasn't come to the forum since then.

But Zhang Heng noticed the last message, it was a day ago, the ID was called Traveler No. 1, just a clueless sentence.

- Are you the Fermi Paradox? So was that set of things just for writing science fiction?

Zhang Heng glanced at the ID and found that the other party was online.

So I sent a private message to the other party.

INTERVIEWER Can you tell us about Fermi's paradox?

Voyager One replied

- Wait a minute.

It was about two minutes before he sent a second message.

——The boss was going around outside just now, and he couldn't let him find out about me fishing at work, you want to know the Fermi paradox, can't you just go directly to Baidu on the Internet?

- No, there was a science fiction article before, and you left a comment below.

- Oh, oh, oh, you said that, probably the wrong person. That guy is not from this forum.,It's an ID in the previous Douban city group.,It's a very mysterious guy.,Only log in at 5:30 to 6:00 every day.,You will never see him before 5:30 and after 6:00.,Punctual is like a robot.。

Zhang Heng was silent, if this ID was really Lin Sisi, this situation would probably occur because Lin Sisi's parents limited her time on the Internet, and many families with young children would have similar regulations, but I didn't expect this to make the Fermi paradox extremely mysterious in the group.

- Do you know anything about her?

Zhang Heng asked.

- She? Is Fermi Paradox a girl? Speaking of which, she doesn't seem to have said whether she's a man or a woman, and I don't know her too well, after all, her activity time happened to be when ordinary people got off work, and she was very serious, and sometimes she would keep debating with you for a small issue, until you surrendered, or she was a little offline, but her level was quite good, and some people had doubted whether she was a teacher in a research institute or a school before.

- Oh?

- By the way, the group also organized an offline stargazing activity before, and Fermi asked a lot of questions, saying that he and two friends would come, but then he said that his family did not agree and could not come, yes, that is, 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 this time they should have found the right person, Zhang Heng continued to type after that.

- What was that set of things you were talking about earlier?

- Oh, didn't "The Three-Body Problem" win an award last year, so the topic of communicating with aliens has been particularly hot recently, and then I remember about three weeks ago, Fermi Paradox also posted a post saying that she deciphered a piece of radio radiation from space.

- Huh?

Voyager One is very patient, of course, it may also be idle, and explained by the way.

- The so-called radio is actually a kind of electromagnetic radiation, but it can penetrate interstellar matter to bring galaxy information at a greater distance, scientists use radio telescopes to observe and study radio waves, before the world's largest radio telescope in Puerto Rico, called the Arecibo radio telescope, with a diameter of 350 meters, but this year, our country's 500-meter-diameter FAST radio telescope should be almost completed in the second half of the year, and then it should be the world's largest radio telescope.

Voyager One said proudly.

- I know what a radio telescope is.

Zhang Hengdao.

- Actually, I'd like to know more about how the Fermi paradox deciphers radio radiation.

- Wait.

The enthusiastic Voyager No. 1 immediately boarded Douban after speaking, but two minutes later, it was a sigh.

- Why is that post missing.

- What's the title?

Zhang Heng asked.

- It's called "I Deciphered a Piece of Radio Radiation", Fermi paradox said that she found a piece of radio radiation contained important information, but at that time no one in the group believed it, because radio is generally emitted by celestial bodies, and there is no practical meaning, of course, its essence is a kind of electromagnetic radiation, which can theoretically be used to store information, but it is hard to imagine that there is extraterrestrial life that can transform a pulsar into a radio transmitter or something, so at the time everyone thought she was joking or something, And this time she didn't refute it for the first time, and this matter is over.

Zhang Heng retrieved the title of the post when he heard this, but found that the information downloaded by both Baidu spiders and Google crawlers had also been deleted, Zhang Heng remembered the guy he met before who could modify the surveillance video, and there were obviously computer masters among those things.

"What 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 matter, it's gone, it's gone, anyway, I've learned how to decipher it, but it seems that it is only useful for the radio radiation she emits, and then I checked all the radio radiation records that I can find on the Internet, and there is no part of hers, no matter how you look at it, she made it up herself.
