"That isosceles triangle is not a Dyson sphere."
A castle suspended above the equator of the Pacific Ocean.
Chen Yu faced the camera and said word by word: "It's the Galaxy Internet!"

[When I put the question mark, it was not because I was confused, but because I thought you had a question.]
[What the hell?]
[The Internet... is still the emmmmm of the Milky Way.]
[UP Lord, are you serious?]
[Can I chat with aliens on WeChat?]
[Have fun in the future.]
[Isn’t the Octopus super cool when he plays King Pesticide?]
[Confused.]
[Confused +1]
After a brief silence, question marks erupted in ten live broadcast rooms at the same time.
Professionals and official staff in the astronomical community also looked at a loss.
They thought of many explanations.
Dyson sheets, wormhole devices, scientific research sites, and even two-way foils have all been considered.
But I didn’t expect the answer “Galaxy Internet”…
"boom!"
"Is he kidding me?!"
In the New York Observer Hall, Representative Jian Guo couldn't help but burst into laughter: "Why is there 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 leader of Chrono UP is not our human Internet. It should have other meanings."
"for example?"
"have no idea."
“…”
“…”
In the hall, representatives from the two countries looked at each other, not knowing what to say. After a long silence, he could only turn his head at the same time and look at the big hanging screen.
…
Seeing the barrage of comments on the watch, Chen Yu nodded: "Everyone's reaction was not what I expected. When I read this explanation in newspapers, I couldn't believe it. An isosceles triangle with a thickness of no more than 5 microns , what does it 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 "Civilization Shines Moment" newspaper and showed the analysis chart to the 46 million viewers in the live broadcast room.
"As mankind's understanding of outer space deepens, in 2060, people finally realized that communication between interstellar civilizations is very difficult. There are two aspects of difficulty, known as the 'two barriers to civilization communication'."
"1. Positioning."
"2. Energy consumption."
"For example, using radio to establish communications within a mere five light years consumes extremely terrifying energy. No civilization can afford it. Switching to lasers can reduce energy consumption and requires very high accuracy. On the large scale of the Milky Way, It doesn’t apply.”
"Even if we exhaust the limits of current human technology, the information sent out will be very small. A distance of just one hundred light years is equivalent to listening to the chirping of mosquitoes on the Great Wall on the moon."
"The farthest electromagnetic waves generated by humans only stay within the solar system. Beyond the solar system, they are covered by cosmic microwaves."
He stretched out his fingers and tapped the pages of the book. Chen Yu smiled: "Obviously, by the end of the 21st century, human beings are unable to shout louder. The universe is really too big. It is so big that it is despairing."
"There was once a novel called "The Three-Body Problem", which used stars as amplifiers to allow surrounding civilizations to detect human voices. However, this method still has its limitations. First, the distance is limited, and secondly, it is not stable. One launch can only transmit information once. In a complex cosmic environment, it can easily be ignored by alien intelligent civilizations."
"This is like the gravitational waves discovered in 2018. If the detector is built for a while longer, this gravitational wave will be missed forever and will not be detected by humans."
"So, in 2090, the astronomical community took a different approach and proposed a communication method called the "Giant Object Network Law."
"That is, build a giant structure around a stable main sequence star, such as the sun. A standard triangle is the best, and create an artificial planet transit scene! Let all intelligent civilizations nearby at least 10,000 light years be able to discover its strangeness. shape!"
"Depending on the strength of the civilization, giant structures of different areas can be built. As long as the brightness of the sun blocked exceeds 2% in one direction, it will attract the attention of intelligent civilizations in that direction in the long run."
"If the giant structure is allowed to rotate 360° around the sun, all, all, all civilizations within 10,000 light-years will determine the anomalies of the solar system and determine whether there is civilization in the solar system through long-term observation. In this way, lonely life will successfully break through It blocks the distance between the universe and allows civilizations to communicate with each other."
"And the more technologically advanced a civilization is, the less restricted it is by distance. Abnormal changes in this star can be detected even 20,000, 50,000, or 100,000 light-years away."
Under the stunned gaze of all the audience, Chen Yu closed the newspaper and said seriously: "It is in this way that Tabby Star announced its existence to the entire universe. And then it was noticed by us. This is thanks to the giant structure of Tabby Star The area is very large, causing a 22% decrease in luminosity. Presumably intelligent civilizations in half the galaxy would be able to notice it as long as they reach the level of people on earth."
"This way of sharing information between intelligent civilizations is called the Galaxy Internet!"
[Fuck! I was dumbfounded.]
[Main sequence stars are stable! As long as there are changes, they will be noticed by the surroundings! Awesome!]
[This kind of operation is so sexy...]
[When more and more civilizations establish this kind of triangle, they can transmit various information to each other through regularity! Real Internet!]
[Isn’t it timely? The speed of light is too slow.]
[What timeliness is required? Is this equivalent to uninterrupted broadcasting? The notification scope may cover the entire galaxy! Simple messaging is enough.]
[What else can you say? Why can’t I understand... (crying)]
[A simple explanation is that the originally normal sun shines abnormally, and aliens will know that there is someone here when they see it.]
[Then we can also do it on the sun, right? Let the Kingdom of the Universe quickly declare ownership of the Milky Way!]
[Am I the only one who feels like this is seeking death?]
[+1. Even if the dark forest is a concept in science fiction, it must be guarded against attacks from advanced civilizations.]
[It can be done far away from the solar system...]
Standing there, waiting for the excitement of more than 40 million people to subside, Chen Yu walked out of the camera, picked up the white express box, and put it down: "Dear viewers, inside this box is the focusing Hubble Telescope that will be launched in 2105. .”
"NASA is specially designed for Tabby Star observation. Through the light information simulation filling technology built into the telescope, the optical map of the star's surface can be accurately displayed. With simple computer calculations, clear close-up photos can be displayed! "
"Next, I will fly into space, aim at Tabby's Star, and photograph the still-running Milky Way Internet a hundred years in advance."
Stepping forward to the portal, Chen Yu explained while operating the console: "The current time is February 21, 2021. According to the records in newspapers, it is the time period when Tabby's star dims. This is Very, very lucky.”
"Because, not only can we see the isosceles triangle with ten Jupiter surface areas, but we can also see a large group of vampires adsorbed around the triangle... "
