"That isosceles triangle is not a Dyson sphere. ”

Suspended in the air inside a castle on the equator of the Pacific Ocean.

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

【？？】

【？】

【？？？】

【?? 】

[When I put a question mark, I don't think I'm wondering, but I think you have a problem. 】

[What's that?]

【Internet ...... Or the emmmm of the Milky Way. 】

[Up Lord, are you serious?]

[Can you chat with aliens on WeChat?]

[It's good to play in the future.] 】

[That octopus star people play king pesticide is not super **?]

[Confused. 】

【Confused +1】

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

Professionals and officials in the astronomical community were also at a loss.

They have thought of many, many explanations.

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

I didn't expect the answer "Galactic Internet......

"Bang!"

"He's kidding, right?!"

In the Jonew Observer Hall, the representative of Jianguo couldn't help but slap the case: "How can there be such a strange thing?!"

"Hmmm......"

The middle-aged group leader on the right came back to his senses, pondered for a moment, picked up the microphone and said, "Perhaps, the Internet in the mouth of the master of time and space is not the Internet of our human beings. There should be something else. ”

"For example?"

"I don't know. ”

“……”

“……”

In the hall, the representatives of the two countries looked at each other, not knowing what to say. After being silent for a long time, he could only turn his head at the same time and look at the hanging big screen.

……

Seeing the overwhelming barrage tide in the watch, Chen Yu nodded: "Everyone's reaction is not what I expected." When I read this explanation in the press, I couldn't believe it. What does an isosceles triangle with a thickness of no more than 5 microns have to do with the Internet?"

"I'll understand when I see the explanation on the next page. ”

As he spoke, he opened the 120 pages of the newspaper "The Moment of Civilization Shining" and showed the analysis chart to the 46 million viewers in the live broadcast room.

"As humanity's understanding of outer space deepens, in the year 2060, it will finally be recognized that communication between interstellar civilizations is difficult. There are two aspects of difficulty, which are called 'two barriers to civilized communication'. ”

"First, positioning. ”

"Second, energy consumption. ”

"For example, using radio to establish communication within five light years consumes extremely terrifying energy. No civilization can afford it. Replacing it with a laser, the energy consumption can be reduced, and the requirements for accuracy are very high. It doesn't work on the large scales of the Milky Way. ”

"Even if the limits of humanity's current technology are exhausted, the message sent is very small. Just 100 light-years away, it's the equivalent of listening to the cries of mosquitoes on the Great Wall on the moon. ”

"The farthest electromagnetic waves that occur in human beings are only in the solar system. Beyond the solar system, it is covered by cosmic microwaves. ”

Stretching out his finger and tapping on the page, Chen Yu smiled: "Obviously, by the end of the twenty-first century, human beings are not capable of shouting their voices louder. The universe is so big. It's hopelessly big. ”

"There used to be a film called "The Three-Body Problem", which used stars as amplifiers so that the surrounding civilizations could discover human voices. However, this approach still has its limitations. The first is that the distance is limited, and the second is that there is no stability. A message can only be delivered once at a time. In the complex cosmic environment, it is easy to be ignored by extraterrestrial intelligent civilizations. ”

"For example, the gravitational wave discovered in 2018, if the probe had been built a little later, this gravitational wave would have been missed forever and would not have been detected by humans. ”

So, in 2090, the astronomical community came up with a new way of communication called the "Giant Cyber Law". ”

"That is, building a megastructure around a stable main-sequence star, such as the Sun. It is best to use the standard triangle to create an artificial planetary transit! Let all the intelligent civilizations in the vicinity at least 10,000 light-years be able to discover its anomaly!"

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

"If the megastructure is allowed to rotate 360° around the sun, all civilizations within 10,000 light-years will determine the anomalies of the solar system and determine whether there are civilizations in the solar system through long-term observation. In this way, the lonely life has successfully broken through the blockade of cosmic distance. Let civilizations communicate with each other. ”

"And the more technologically advanced the civilization, the more unrestricted it is by 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 solemnly: "Tabi Star is using this way to announce its existence to the whole universe. And then we noticed. This is due to the large size of Tabi's giant structure, which causes a 22% drop in luminosity. Presumably, the intelligent civilization of half of the galaxy should be able to notice it as long as it reaches the level of earthlings. ”

"This way of sharing information between intelligent civilizations is called the Milky Way Internet!"

I'm stupid. 】

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

[This kind of operation is so sassy......]

[When more and more civilizations build this triangle, they will be able to transmit various information to each other through regularity!

[Timeliness is not good, is it? The speed of light is too slow. 】

[What timeliness is required? This is equivalent to uninterrupted broadcasting? The announcement range may cover the entire galaxy! Simple information transmission is enough. 】

Why don't you understand me...... (crying)】

[The simple explanation is to make the original normal sun shine abnormally, and the aliens will understand that there are people here when they see it.] 】

[Then we can also get it on the sun, right? Quickly let the universe come up and announce the ownership of the galaxy!]

[Am I the only one who feels like I'm dying?]

【+1。 Even if the dark forest is a science fiction concept, it cannot be unguarded against the attacks of advanced civilizations. 】

[You can get ...... far away from the solar system]

Standing in place, waiting for the excitement of more than 40 million people to decrease slightly, Chen Yu walked out of the camera, picked up the white express box, and put it down: "Audience friends, inside this box is the Hubble Telescope that was launched in 2105. ”

"NASA is specifically designed for Tabi star observations. The telescope's built-in optical information simulation filling technology can accurately display the optical spectrum of the star's surface. With a simple computer calculation, you can show a clear close-up photo!"

"Next, I'm going to fly into space, aim at Tabi, and shoot the Milky Way Internet that is still running a hundred years in advance. ”

Walking to the portal, Chen Yu explained while operating the console: "The current time is February 21, 2021, and according to the records in the newspaper, it is the time period when Tabi's starlight dims. It's very, very lucky. ”

"Because, not only can we see that isosceles triangle of the ten Jupiter surface areas, but we can also see a large group of vampires attached to the triangle......"
