If the universe is compared to a huge forest, then the earth civilization is undoubtedly a young beast that has just come out of its infancy, if this young beast is not well covered and unscrupulously exposed to those predators, even if it is observed that 99% of the predators of this young beast are well-intentioned, but as long as one percent of the predators have malicious intentions, then this young beast may become food for predators.

In the forest, lizards change color, turtles have shells, hedgehogs are covered with thorns, and the young beast of Earth civilization has no means to protect itself.

Thinking about it, Xiao Li shuddered.

If his reasoning is correct, then it is very likely that the young beast of Earth has been observed by a considerable number of predators, and there may be some predators who have already launched attacks on the civilization of the earth, but because of the distance, these attacks have not yet reached the earth.

"Hopefully my guess is wrong."

Xiao Li took two steps irritably, the guess was too terrible, so terrible that he didn't want to face it at all, "But no matter what, I have to disguise myself after I go back." ”

"The means of camouflage is photon sequencing."

Photons are sequenced into an Earth, or even a solar system, and are used to transmit information and confuse observers into believing that there is no civilization in the solar system.

It is a means of camouflage, similar to the discoloration of a chameleon.

"But there are two difficulties." Xiao Li asked two questions in his heart, "First, the light source. ”

"Covering the earth and even the solar system requires a huge light source to release photons, ordinary means simply can't do it, although the nuclear bomb on the earth claims to be many times the brightness of the sun, but it is an instantaneous explosion, in terms of continuity, 100,000 nuclear bombs together are not comparable to the sun."

"Second, photon sequencing."

"Although I know that Loki's phantom is achieved through photon sequencing, the engineering difficulty of photon sequencing for a person is not the same as that of a planet or even a galaxy."

Two problems bothered him.

He tried to use his brains to find a solution, "photon sequencing is a good solution, through the way of cloud computing to integrate the computing resources of supercomputers on the earth, so that they can jointly calculate the photon sequencing of the solar system, so as to create an approximate real solar system...... It's a huge project, but it's necessary to disguise yourself. ”

"The problem with the light source ......." Xiao Li rubbed his chin and fell into thought, "There is no artificial celestial body on earth that can compare with the sun in light. ”

Some nuclear tests in the laboratory can rival or even surpass the sun in an instant, and there are light sources that continuously emit a large number of photons, but the former is not sustainable, and the brightness of the latter is a problem.

"How can I fix it?"

Xiao Li walked back and forth with his hands behind his back, he thought of several plans in his head, but they were all rejected one by one, and there was currently no artificial celestial body comparable to the sun in terms of duration and brightness.

If it is replaced by a large number of artificial celestial bodies, it is difficult to say whether it will work or not, but the project is so huge that it is definitely not something that the earth civilization can afford.

"So how do you fix it?"

Xiao Li was a little irritable in his heart, the more he thought about it, the more irritable he became, the more irritable he became, and gradually fell into a circle of thinking.

At that moment, a light suddenly crossed his eyes and slammed into the fountain next to him.

Suddenly, a flash of light flashed in his heart, "That's right, it's light." ”

Xiao Li looked up and saw Captain America, Steve. Rogers put down his shield, and the light just now was clearly Captain America's Steve. Rogers' shield reflects light attacks from Loki.

But he didn't care about this, he grabbed the flickering light in his heart, and the whole person became excited.

"It's light."

Xiao Li clapped his palms, his face was very excited, "Why should I use an artificial celestial body as a light source?" Isn't there one of the largest natural sources of light in the solar system? ”

The sun, the largest natural light source in the solar system, as a star, it is the center of the entire solar system, not only because its gravity captures a large number of planets, but also because it provides light and heat for the planets of the solar system, but most of the light and heat of this star does not shine on the planets, and more of its light and heat are scattered in the universe.

"The lost light and heat can be fully utilized." Xiao Li's right fist slapped on his left palm, "I can build some artificial celestial bodies to fly around the sun and reflect back the light scattered by the sun in the universe, so that there will be a large number of photons?" ”

The photons released by the sun are more than enough to cover the entire solar system.

"No...... It's not all. Xiao Li's thoughts diverged, "I am completely obscured by the leaves in front of me, and building an artificial celestial body near the sun can not only refract the light source to create camouflage, but I can also collect energy." ”

Xiao Li remembered an idea from 1960.

In 1960, physicist Freeman. Dyson came up with the idea of building a large number of artificial objects in the vicinity of the sun, which were made up of receivers and energy converters that could easily absorb and convert the radiation emitted by the sun.

These man-made celestial bodies are called Dyson spheres.

The idea of the sun as a giant fusion reactor was called a wild dream at the time, and even after the 21st century, when the concept of an artificial satellite became quite popular, it was still considered impossible by many.

The reason is simple, because building a large number of artificial celestial bodies to cover the sun requires a huge amount of resources.

According to scientists' calculations, in order to build an artificial celestial body of that level, human beings need to at least dismantle Jupiter, the largest planet in the solar system, of course, not Jupiter, Jupiter is a large balloon, and if you want to dismantle Jupiter to build a Dyson sphere, you must first quantify Jupiter and then materialize it.

But at that level of civilization, what Dyson spheres still need to be built? Just find a planet the size of Jupiter that can be energized, which is not much worse than the energy that the sun radiates for 5 billion years.

Based on the loss of 4 million tons of mass per second from solar fusion, the energy released by the Sun's main-sequence phase is only two-thirds the mass of Jupiter.

But just because you couldn't do it at that time doesn't mean you can't do it now.

A new era in which the number of robots and spaceships is being created at an explosive rate, coupled with a breakthrough in anti-gravity, the civilization of Earth is definitely capable of building a Dyson sphere.

"Although the mainstream technology is nuclear fusion technology now, there is no shortage of energy for the time being, but it is also quite cost-effective to be able to collect energy at the same time as building camouflage."

"Still, I can think outside the box."

Xiao Li continued to think deeply, "Simulating the entire solar system is a huge burden for supercomputers, even if other supercomputers join the ranks of computing through cloud computing, it is also a very big burden. ”

"But with the Dyson ball it's different."

"The Dyson sphere can obscure the sun's light source, so that the sun's light is no longer scattered in the universe, and from the background of the universe, the solar system is a huge black curtain, and this kind of black curtain is very common and ordinary in the universe."

"When the time comes, I will only need to disguise the Earth as an ordinary planet by photon sorting."

The camouflage of a planet and the camouflage of an entire solar system are not the same in terms of computational requirements.

"The only problem is how to disguise the Earth as an ordinary planet, but this camouflage can be calculated by the computer."

"Well, what's good to disguise it as? Normal planet or gas planet? In the gaseous state, there is the least chance of life on the gaseous planets...... Although I don't know if there is life on gas planets, from the perspective of Earth civilization and lizard civilization, gas planets are the least likely to have life. ”

"If there really is an observer, when the observer observes that the Earth is a gas planet, I am afraid that they will look away."

How many planets are there in the universe? I can't count them, if the observer wants to observe every planet, I'm afraid that the observer will be exhausted, Xiao Li guessed, the observer must determine whether there is a civilization in the planet or galaxy through the traces of civilization in the galaxy or even the river system.

He felt that his guess was most likely correct.

The earth civilization is not alone, but since the existence of the earth civilization, only one lizard civilization has discovered the earth, and the other civilizations do not seem to have any interest in the earth civilization, even the unknown existence that attacked the lizard civilization has no awareness of the earth that is close at hand.

It's as if the earth's civilization doesn't exist at all.

This fact corroborates Xiao Li's conjecture, he feels that the reason why the earth civilization has not been discovered is entirely because the earth was still active in the earth at that time, and it did not go to the wider space at all, so the unknown existence that attacked the lizard civilization attacked the lizard civilization, but turned a blind eye to the earth civilization that was close to the lizard civilization.

If his assumption is correct, then camouflage is necessary.

Under the dark cosmic background, the Dyson sphere hides the solar system in the same darkness as the background color of the universe, and from the cosmic level, the dark solar system is completely invisible, so as to avoid the attack from predators to the greatest extent.

Just like a chameleon lying on a leaf, if the predator does not distinguish carefully, it is easy for the chameleon to escape from the predator, and there are hundreds of millions of trees in the forest of the universe, and the predator cannot carefully distinguish every leaf on every tree, so that the young beast of earth civilization can avoid the attack from the predator to the greatest extent.

Just when Xiao Li was about to like his thoughts, a burst of noisy music suddenly came, interrupting his praise, he raised his head and immediately saw a figure flying over.
