Hide yourself?

Everyone in the square was so shocked by Xiao Li's series of words that their brains were dizzy, so many great truths were stuffed into their heads through their ears in an impassioned way, and they felt that their heads were not enough, whether this was a speech or a speech.

"The Dyson ball is the way to hide yourself." Xiao Li raised his hand, and the image of a sun was in his hand, "This is the sun, the great father who has given us the vitality of civilization." ”

"He is enthusiastic and unrestrained, releasing light and heat to the outside world all the time, and these lights and heat also transmit information about our interstellar activities to farther places."

"Just as our Hubble Space Telescope and Gaia Space Telescope judge information through the light of distant galaxies, it is possible for the enemy to observe whether there is civilization in the solar system by collecting information transmitted by light."

"When we have not yet stepped into space, this disadvantage does not exist, because we have not yet come out of our infancy, and we who operate inside the planet are invisible to extraterrestrial civilizations, but now it is different, we have come out of our infancy and started to operate in space, and sooner or later our information will be transmitted to the eyes of unknown civilizations."

"That's the coordinates exposed."

Coordinates exposed!

Everyone became nervous, the blow of the lizard civilization was just echoing in their ears, and now it was the turn of the earth, and this realization made them frightened all of a sudden.

"In order to prevent the blow, I looked up some information from the past and finally found the Dyson ball." Xiao Li clasped his hands together, and the black iron wrapped the sun inch by inch, and the light dimmed in the blink of an eye, "The Dyson sphere is an energy absorption and transformation tool. ”

"It can absorb the light and heat transmitted by the sun and convert it into energy, think about how much energy the sun releases at any given moment!"

"That's the amount of energy that all the reactors on the planet can't multiply by multiplication."

The original purpose of the Dyson sphere was to solve the earth's energy problem.

Before the promotion of cold nuclear fusion, the earth civilization has been limited by energy, many scientists believe that energy is the key to restraining civilization, Dyson thinks that the earth civilization assumes that one day it will embark on the path of interstellar civilization, then the only possibility to restrict it is energy.

In his thoughts, the energy required by the earth civilization in the interstellar era is astronomical, and it is obvious that it is impossible for oil to meet this astronomical amount, even if there is a large amount of oil on other planets, so he wants to find an energy source that can be used once and for all.

Eventually, he found it, and that was the sun.

He calculated that if a wrap or a large number of artificial celestial bodies were built near the sun to receive and convert the energy released by the sun, then the energy needed for the progress of human civilization would be once and for all.

After all, according to current estimates, it will take at least 5 billion years for the Sun to transform into a red giant and eventually a white dwarf due to the depletion of hydrogen reserves.

Therefore, he believes that the sun can provide the energy that human beings need to enter the interstellar civilization.

"The most important thing is that once the Dyson sphere is built, the light and heat released by the sun into the universe will no longer transmit information, and the entire solar system will be shrouded in darkness and invisible from the background of the entire universe."

"It's about hiding yourself."

Without waiting for the people below to react, he immediately said, "Now you can ask your own questions. ”

"If the sun is obscured, are we losing our light?" A reporter raised his hand and said impatiently after Xiao Li's roll call, "If the light is lost, the earth will also be doomed, after all, the light of the sun is indispensable for the earth at this stage." ”

"You understand that there may be a mistake." Xiao Li patiently replied: "In the original version of the Dyson sphere, the earth will face the problem of no light. ”

"But this problem was solved later, that is: the Dyson sphere allows the sun's light to shine on the earth, simply put, the Dyson sphere will refract or transmit a part of the light to the earth after calculating the trajectory, so that the existence of the Dyson sphere does not interfere with the earth's light."

"I believe that with the standards of modern computers, it is possible to calculate a suitable trajectory."

"I have a question." It was Alvin who spoke, "Academician Xiao, maybe you haven't noticed that there is a very important flaw in your Dyson sphere, namely: when the Dyson sphere allows light to be refracted or transmitted to the earth, from the outside world, there is a very important problem, that is, a black celestial body transmits a pillar of light to shine on a planet, which is like a rotating light in the middle of the dance floor, don't you think this astronomical phenomenon is very weird?" ”

"This is to some extent a declaration to the universe that there is a civilization here that is disguising itself, and everyone is coming and attacking."

"That's why you need to disguise."

Xiao Li said with a smile, he had thought of this question for a long time, and this question had indeed bothered him for a long time, but the final idea was disguise.

The traces of light transmission or refraction cannot be hidden, and those information will spread into the universe with the diffusion of light, and it is unrealistic to build a Dyson sphere to wrap the earth in it.

Doing so will only cause the phenomenon of a pillar of light **** coming out of a large sphere and shining on a small sphere, which is a more bizarre astronomical phenomenon, which clearly tells the observer in the universe: Come and see, there is a stupid civilization here that is trying to hide itself.

What is called not to recruit yourself, this is not to recruit yourself.

So he came up with a disguise.

"Disguise false information through the sequencing of photons, and send a wrong message to the universe." With a wave of Xiao Li's hand, the Dyson ball disappeared and was replaced by a solar system.

The solar system is calm, the huge stars and the planets it gravitationally captures rotate according to some predetermined trajectory, it is the solar system, but the only thing that is different from the solar system is dead silence.

Like most galaxies in the universe, this galaxy is very dead and silent, without any trace of life, and any civilization will ignore it as soon as it is observed.

"It's called photon sequencing, and it's a technique that I prepared for the Dyson sphere program." Xiao Li said: "Its principle is very simple, it is to form various real illusions with the help of the arrangement of photons, so as to confuse the enemy. ”

"In my vision, the Dyson sphere is not just a tool to shade the sun, it is also a huge light source, a tool that emits a large number of photons, so that the photons can transmit false information to the universe according to the pre-designed trajectory."

Covering the sun and making the solar system invisible in the universe is one means, and then releasing false information to confuse observers, this is another means, both means go hand in hand, he doesn't believe that the earth civilization can't hide itself?

"Why not just use photon sorting?" Alvin didn't understand, "Why bother building a Dyson sphere?" ”

"Because of the light."

As soon as Xiao Li closed the scene, a sun appeared again, it was like the universe constantly transmitting light and heat, and also carrying the information of the solar system to the depths of the universe, "The light of the sun is too hot, so hot that we can't completely camouflage it." ”

"If we don't shade the sun and continue to let the sun release light and heat, then we will face a very embarrassing problem, that is, the false information we convey and the real information are intertwined and passed on to the eyes of the observer.

After a pause, Xiao Li remembered that most of the people here were Westerners, and immediately explained, "Three hundred taels of silver in this place is a folk tale in China, which tells the story of a man who buried silver in the ground, and left a word on it: 'There is no silver three hundred taels here'. The neighbor Ah Er stole the silver, and also left a note to read: 'Wang Er next door did not steal'. ”

"Not to shade the sun is, in a way, as foolish as the man who buries silver in the ground and writes on it, 'There are no three hundred taels of silver here.'"

"Other than that, it's the light source." Xiao Li said with a smile: "For now, there is no artificial celestial body that can continuously release enough photons to cover the entire solar system like the sun. ”

"Although there are many little suns in human experiments, everyone should be called what the little sun is!"

Alvin immediately laughed.

Others may not know, but he doesn't know? Those so-called little suns actually refer to having explosions comparable to the sun in an instant, but when it comes to continuity, what can compare to the sun that has been shining for billions of years?

"So the essence of the Dyson sphere is also a giant man-made celestial body."

"It can refract the sun's rays so that the sun's rays are intertwined according to our calculations, thus camouflaging a dead solar system."

"And we're going to be in this solar system."

"It's about hiding yourself."

Xiao Li said all his thoughts in one go, but in fact, he was ingratiated.

He talks about the Dark Forest first, and then the Dyson Sphere, deliberately making the public accept his words before they have time to think, so that they will focus on the Dyson Sphere instead of looking for the flaws in the Dark Forest.

The theory that cannot be verified or falsified is itself a theory full of flaws, it is a standard theory of public reason, and it always looks at sophistry, and Xiao Li happens to be not good at sophistry.

Alvin immediately praised, "The establishment of the Dyson sphere is really imminent. He was persuaded by Xiao Li, and from the bottom of his heart, he believed that it was necessary to build a Dyson ball.

"It's just that building a Dyson Sphere requires a lot of resources!"

"Yes, so we need the participation of the whole people, the power of the whole civilization to build the Dyson sphere." Xiao Li immediately fanned incessantly, "For the continuation of civilization and the future of civilization, I implore you to build a Dyson sphere together." ”
