Industrial survey, it turned out that the sweater was worn inside out?

Chapter 407: Real and fake alien Li Kui! (First update!)

Along with Feng Jingwei's voice, a piece of note data was transmitted!

Then, the smart speaker in the office started to play this note!
Tick-tick-tick-tick-tick-tick-tick

Lin Yu has heard a lot about the clutter in the universe since he started the Tiangong Project!

Compared with this sound, those clutters are all signals emitted by neutron stars, white dwarfs, and various large celestial bodies!
These signals are intertwined, and after translation, there is no pattern at all, let alone the gentle and rhythmic sound it is now!

After frowning and thinking for a moment, Lin Yu raised his hand and adjusted the music playback mode in the room to theater mode!

At the same time, copy and paste this sound to turn it into a song!
Then, click play!
As the short prelude sounded, the gentle and orderly ticking sounded again!

His whole body started to move according to the beat!
After listening to this piece of music over and over again for a long time, he turned off the speaker, connected to Feng Jingwei's communication again, and asked the person on the other end of the video:

"What did you say the situation was like 50 years ago?"

Hearing Lin Yu's question, Feng Jingwei on the other end of the video stretched out his hand and scratched his head, but stopped talking!

After struggling for a while, he seemed to have sorted out his words and explained:

"Around the 70s, Lao Maozi and America competed with each other. At that time, they wanted to go to space one by one!"

"First Gagarin went into space and became the first human being to land in space, and then Apollo became the first human being to land on the moon!"

"We were very poor at the time and didn't have those things, but we couldn't just watch them do it!"

"So, we set up several monitoring stations across the country, and then listened to the sounds from the universe!"

"Probably April of 73!"

"One day, several monitoring stations across the country reported hearing a unique signal!"

"Then these monitoring stations reported the unique signals detected to the Academy of Sciences!"

"But at that time, because of the lack of understanding of astronomy, the Academy of Sciences believed that this sound should be the work of America or Lao Maozi!"

"So, I just recorded the data of this unique signal and threw it aside!"

"As for why we were able to find it out this time, it's because there was a person who was monitoring it, and now he has grown into a master in astronomy!"

"He saw this signal fluctuation and recognized it at a glance!"

While he was explaining, another piece of data was also passed over!

Here are some photos!
In the photo, there are yellowed data strips, and on the originally white paper, there are crests and troughs carved by ink!
That is the most intuitive manifestation of signal fluctuation when observed by humans!
Seeing these photos, Lin Yu tapped his fingers a few more times to analyze the signal fluctuations of the music!
Then, slowly approach the yellowed data tape!

It's exactly the same!
At this moment, Lin Yu's scalp went numb!
But soon, he turned back and asked Feng Jingwei:

"Is it possible that this signal is actually a good thing done by Lao Maozi or America?"

However, after hearing his words, Feng Jingwei immediately rejected it: "Impossible!"

"Because our base station on the moon also received a similar signal!" As he spoke, another piece of data appeared in front of Lin Yu!
When Lin Yu saw this data, Lao Ma also appeared quietly. He frowned, looking like he was bitter and resentful!

After Lin Yu finished reading the previous data, he said: "I just retrieved the data from several large observation stations in the world!"

"At the same time that we received the data, large observatories in the northern hemisphere between 75 degrees east longitude and 125 degrees east longitude received similar signals!"

"But except for our people, other observatories are just messing around, so they don't pay attention at all, so they haven't taken any action yet!"

As he spoke, the data in front of Lin Yu turned into a model of Blue Star!
In this model, between 75 degrees and 125 degrees east longitude, in the northern hemisphere, a dozen red dots are flashing!
Among them, there are those from Yingguo, those from Xiba, those from Bharat, and several other countries!
These red dots flashed for about 10 seconds, and then the data they observed appeared in front of Lin Yu!
More importantly, none of the monitoring stations clearly detected where the signal came from!

After seeing this, Lin Yu finally believed that this so-called signal came from outer space and was not the mischief of his family!
The signal from 50 years ago appears again!
And it’s still the same signal!
Rubbing his temples with his hands, Lin Yu shouted in a low voice: "Old Ma, bring up the orbit map of the Blue Star when the data was received three days ago!"

As soon as he finished speaking, the blue star model in front of him turned into a model of the solar system!

Then the model is enlarged!

On the day he received the signal, the Blue Star's movement posture appeared in front of him!
The time when the signal was received was July 26, 7!
During this time, the Blue Star has moved near the aphelion, and the area directly illuminated by the sun is the northern hemisphere!

And the time when the signal was received was during the day!

At that time, the northern hemisphere was facing the sun!

At that time, the only constellations located above the sun were...

After carefully recalling the constellations that could be seen, Lin Yu found that using triangulation method, it was impossible to deduce where the signal was sent out!

In the Northern Hemisphere, in July, the constellations that can be seen are: Cygnus, the Summer Night Triangle, the Big Dipper, Draco, Hercules, Corona Borealis, Serpens, Libra, Ophiuchus, Serpens, Libra, Sagittarius, Scorpio!
The distance between each name is at least a few light years!

Even the area of ​​the Great Wall of Corona Borealis is dozens of times larger than the Laniakea Supercluster where the Milky Way is located!
After staring at the constellations displayed in front of him for a while, Lin Yu suddenly asked:
"Old Feng, do you think there is a possibility that this signal is actually a regular searchlight!"

"This searchlight is operating according to certain rules!"

"Then, every 50 years, we receive a signal from him!"

"Actually, he didn't send it on purpose. He just swept it like a searchlight and we received it by chance!"

In the video, Feng Jingwei heard this, nodded slightly and replied: "The think tank has found some astronomical experts, and after analysis, they also said that it is a similar situation!"

"The problem now is that we can't confirm the direction, distance, or time of this signal!"

"The think tank infers that since this civilization uses searchlights to find other civilizations!"

"Then there's a good chance he's not a good guy!"

"So our top priority is to find out how far away this guy is from us!"

"You also know that there are other people on this planet who are not worthy of being called human beings!"

"If these spies cause trouble, it will really be over!"
