"That isosceles triangle is not a Dyson ball."

Hanging inside a castle on the Pacific equator.

Chen Yu faced the camera and said word by word: "It's the Galaxy Internet!"

【??】

【?】

【???

【??】

[When I asked the question mark, I was not confused, but thought you had a problem.]

【What thing?】

[The Internet... is still the emmmm of the Milky Way.]

【Up master, are you serious?】

【Can you chat with aliens on WeChat?】

【Funny fun in the future.】

[Isn't that octopus star man playing King of Pesticides super**?]

【Damn.】

【Damn +1】

After a brief silence, question marks broke out in ten live broadcast rooms at the same time.

The professionals and official staff in the astronomy industry were also confused.

They have thought of many explanations.

Dyson tablets, wormhole devices, scientific research points, and even two-way foils have been considered.

Only I didn't expect the answer to "Galaxy Internet"...

"Bang!"

"He's kidding, right?"

In the Observer Hall in New York, representative Jianguo couldn't help but shoot the table: "How could there be such a strange thing?!"

"Um……"

The middle-aged team leader on the right came back to his senses, pondered for a moment, picked up the microphone and said, "Perhaps, the Internet mentioned by the super-time and space up master is not the Internet of our humans. It should have other meanings."

“What about?”

"have no idea."

“…”

“…”

In the hall, representatives of the two countries looked at each other, not knowing what they should say. After a long period of silence, they could only turn their heads at the same time and look at the hanging large screen.

...

Seeing the tide of black and storm in the watch, Chen Yu nodded: "Everyone's reaction cannot be as expected. When I look at this explanation in newspapers, it is hard to believe it. What does it have to do with the Internet that is not more than 5 microns in thickness?"

"I will understand when I see the explanation on the next page."

As he said that, he opened 120 pages of the newspaper "Shining Time of Civilization" and displayed the analysis to the 46 million viewers in the live broadcast room.

"As humans deepen their understanding of outer space, in 2060, people finally realized that communication between interstellar civilizations is very difficult. There are two aspects of difficulty, which is called the 'two obstacles to civilized communication'."

“One, positioning.”

"Two, energy consumption."

"For example, using radio to build communication within a mere five-light years, the energy consumed is extremely terrifying. No civilization can afford it. If it were a laser, the energy consumption could be reduced, and the accuracy requirements were very high. It is not applicable to the large scale of the Milky Way."

"Even if the limits of human technology are exhausted, the information sent is very small. A distance of only a hundred light years is equivalent to listening to the cry of mosquitoes on the Great Wall on the moon."

"The farthest electromagnetic waves that humans have only stayed in the solar system. If they transcend the solar system, they are covered by cosmic microwaves."

He stretched out his finger and tapped the pages of the book. Chen Yu smiled: "Obviously, by the end of the 21st century, humans are not able to shout their voices louder. The universe is so big that it is desperate."

"There was once a movie called "The Three-Body Problem", which used stars as amplifiers to allow surrounding civilizations to discover human voices. However, this method still has its limitations. First of all, the distance is limited, and secondly, it is not stable. Information can only be transmitted once in a time. In a complex cosmic environment, it is easy to be ignored by alien intelligent civilizations."

"This is like the gravitational wave discovered in 2018. If the detector is built for a period of time, this gravitational wave will be missed forever and will not be noticed by humans."

"So, by 2090, the astronomy community took a different approach to propose a communication method called "Jiuwu Network Law".

"That is, build giant structures around a stable main sequence star, such as the sun. The best shape is to create artificial planetary transits! All intelligent civilizations nearby, at least ten thousand light-years can discover its abnormality!"

"Depending on the strength of civilization, giant structures of different areas can be built. As long as the brightness of the sun is blocked by more than 2% in one direction, it will attract the attention of smart civilization in that direction in the long run."

"If the giant structure is allowed to rotate around the sun 360°, all civilizations within ten thousand light years will determine the abnormality of the solar system and determine whether there is a civilization through long-term observation. In this way, the lonely life will successfully break through the blockade of the universe distance and allow various civilizations to communicate with each other."

"And the more developed the civilization, the less restricted the distance. Even 20,000, 50,000, or 100,000 light-years away, abnormal changes in this star can be found."

Under the stunned gaze of all the audience, Chen Yu closed the newspaper and said seriously: "Tabi Star uses this method to announce its existence to the entire universe. We have noticed it. Thanks to the huge structure of Tabi Star, it has caused a 22% reduction in luminosity. I believe that half of the galaxy's intelligent civilization, as long as it reaches the level of the earthlings, should be noticed."

"This way of sharing information between smart civilizations is called the Galaxy and Internet!"

【Damn it! I was stupid to hear it.】

[The main sequence star is stable! As long as there is a change, it will definitely be discovered around you! Awesome!]

【This operation is so sensual…】

[When more and more civilizations establish this triangle, they can transmit various information through regularity! Real Internet!]

[Is the timeliness not good? The speed of light is too slow.]

[What timeliness is needed? This is equivalent to uninterrupted broadcasting? The scope of the announcement may cover the entire Milky Way! Simple information transmission is enough.]

[What do you say? Why can't I understand... (cry)]

[Simple explanation is to make the originally normal sun shine abnormally. When aliens see it, they will understand that there are people here.]

[Then we can do it on the sun, right? Let the universe country announce the ownership of the Milky Way!]

[I am the only one who feels like this is a death sentence?]

【+1. Even if the Dark Forest is a concept in science fiction, you must not be protected from attacks from advanced civilizations.】

【You can do it far from the solar system…】

Standing there, waiting for more than 40 million people to lose their excitement, Chen Yu walked out of the camera, picked up the white express box, and put it down: "Friends of viewers, this box is the Hubble Telescope that was launched in 2105."

"Nasa is specially designed for the observation of the Tabistar. Through the built-in optical information simulation filling technology of the telescope, the optical map of the star surface can be accurately displayed. With simple computer operations, clear close-up photos can be displayed!"

"Next, I will fly into space, aim at Tabi Star, and shoot the still-running Milky Way Internet a hundred years in advance."

Stepping forward and walking to the portal, Chen Yu explained while operating the console: "The current time is February 21, 2021. According to the records in the newspapers, it is the time when the tower star light becomes darker. This is very, very lucky."

"Because, we can not only see the isosceles triangle with the surface area of ​​ten Jupiters, but also see a large group of vampires adsorbed around the triangle..."
