The diameter of the solar system is 300 trillion kilometers, and there are eight major planets and millions of asteroids in the core area.
But in the solar system, the mass of the sun accounts for 99.86% of the total mass of the solar system.
This is also the reason why many planets and asteroids orbit the sun.
But there is a problem, and scientists have not yet got a reasonable explanation.
That is, the mass of the Milky Way is only 0.0005% of the Milky Way. Why can it bind trillions of star galaxies?
The scientific community has put forward many conjectures. It was not until 1937, when the radio telescope was successfully built, that people gradually discovered that there was a huge black hole at the center of the Milky Way.
The trillions of stars in the Milky Way revolve around the center of the Milky Way, which are largely affected by this giant black hole.
However, if the devouring power of a normal black hole is placed on a giant black hole in the center of the Milky Way, it does not seem to have that much energy to attract the rotation of celestial bodies throughout the Milky Way.
Scientists can only give a guess, that is, the devouring power produced by larger black holes increases exponentially.
Different civilizations use various methods and names to divide the structure of the Milky Way. For example, the solar system civilization divides the Milky Way into the galactic center, the galactic core, the galactic disk, the galactic halo and the galactic corona.
Integrating the structures of all civilization divisions together, it was found that the divisions with the highest degree of overlap are the divisions of the galactic center. They have amazing consistency. They are all divided by a diameter of 20,000 light-years and a thickness of 10,000 light-years. p>
There is indeed a giant black hole in the Milky Way and the Galactic Center region.
The nearest star is being swallowed by the black hole, and its light is gradually dimming like the setting sun.
At this moment, spaceships representing the characteristics of intelligent life are flying out of the black hole.
It's as if the devouring power of the black hole has no effect on these spacecraft. Not only does it not suck them away, but it keeps sucking them out.
Not only how long has passed, the stars near the black hole have disappeared, replaced by countless spaceships.
If you zoom in closer, you will find that these spacecraft are as big as a star, and the smallest ones are hundreds of kilometers long.
The length of the spacecraft headed by it is more than one million kilometers.
Inside the spaceship, several huge humanoid intelligent beings, about a hundred meters tall according to Earth standards, were gathered around a table and talking.
"Just leave like this?"
"What if?"
"Can we still go back?!"
"There will definitely be a chance, once we integrate the resources of the entire galaxy..."
The leader of the giant paused, as if she didn't even believe this sentence.
"It must be possible!"
The giant on the side saw this and said firmly: "We will definitely be able to go back!"
She understood that if she gave up now, there would be no hope anymore.
The sad mood of several people was slightly relieved and they regained their spirits.
"Now, what should we do?!" the giant leader asked.
"First, we need to find a place to settle the clan members..."
"Secondly, use the resonance fluctuations of dark matter to find the birthplace of intelligent life..."
"Then, establish a galactic empire and start collecting resources..."
……
Soon after, the giants brought countless huge fleets to a medium-mass black hole not far from the center of the galaxy.
"Just destroy their military power and keep the civilians as raw materials..."
"In addition, recording the destruction process and showing it to intelligent life forms when the galaxy is unified can reduce the resistance..."
On the other side of the black hole, there are dozens of galaxies hidden, and hundreds of millions of warships are launched into the sky, ready to fight.
Just now, the spacecraft they were scouting outside suddenly reported that a large number of foreign warships had appeared.
At this moment, a diamond-shaped object shining with white light entered the entrance of the black hole. It was unclear how many sides it had.
"What is this?"
Just when many battleships were at a loss, the multi-faceted diamond-shaped object suddenly began to rotate.
The next second, similar multi-faceted rhombus-shaped objects appeared in every corner and position of this universe.
"Attack!"
Although he didn't know what it was, the highest combat commander of this civilization still issued the order to attack.
Countless attack methods of different shapes roared out, but not a single attack landed on the diamond-shaped object, all the attacks penetrated through.
It's like, although the two can see each other, they are in different dimensions.
"Brush~!"
"Brush~!"
All rhombus-shaped objects suddenly emitted streams of white light and were connected to each other.
Immediately afterwards, the entire universe changed.
The spacecraft began to disintegrate, decomposing from a whole into parts, and then into pieces of matter with initial elements.
Tens of billions of fortifications were reduced to nothing in an instant.
Hundreds of millions of warships have turned into ores of different colors. The intelligent life that was still in the spaceships all lost their protection and froze into ice cubes when facing the universe.
Hundreds of billions of human-shaped ice sculptures float in the vacuum of space, without screaming or wailing.
The diamond-shaped object disappeared and the war ended.
In dozens of galaxies, all high-precision products created by intelligent life have returned to what they should have been.
Only ten trillion humanoid creatures standing naked and confused on the planet are left.
Not long after the diamond-shaped object disappeared, a large number of fleets flew into the black hole and began to move in.
All the indigenous people were driven to their new homes built on more than a million giant warships, and stayed quietly in a corner.
Several giants stood at the top of this universe, overlooking everything with expressionless faces, showing no sadness or joy.
"The resonance of dark matter fluctuations ended, and there was a reaction somewhere in the Milky Way. I don't know how many intelligent beings left their homeland..."
"Send a spaceship to deliver the notice, and bring the converter with you..."
Soon, more than 100,000 spacecraft with a length of 2,000 kilometers left this black hole space and flew to various parts of the galaxy.
……
Solar system.
As the giant battleships left, the fleets belonging to the five major civilizations dared not stay any longer and swarmed into the wormholes. Some chose to go to Proxima Centauri, and some chose to go to the unknown galaxy three hundred light years away.
When part of the fleet returned to Proxima Centauri, they were shocked to find that it was completely empty.
All the fortifications built by the Great Whale Corps of the Mo Dou Civilization are empty.
"That third-level civilization also ran away!"
"Good opportunity, let's go!"
The fleets of the five major civilizations did not stay any longer, and left through the wormholes one after another.
The entire star field around the solar system suddenly became quiet.
The civilized war that lasted for more than a year was summarily ended due to the intrusion of a two thousand kilometer long warship.
……
Moon base.
Zhao Yu walked back and forth uneasily.
The departure of the six major civilizations did not bring him much joy, but instead filled him with sadness.
Where did the battleship that was suspected to belong to the fourth-level civilization go, and what is the purpose of coming to the solar system?
"Appeared!"
At this moment, Uncle Da suddenly said: "The spaceship has appeared, here..."
Zhao Yu stopped suddenly and rushed to the equipment.
Sure enough, traces of the two-thousand-kilometer-long spacecraft were found in the outer reaches of the solar system.
"This location... is far away from us, what are they going to do?!"
Just when Zhao Yu was confused, Uncle Da suddenly said: "Sir, that small spaceship has arrived at Blue Star!"
"What?!"
Zhao Yu was shocked again. The newly appeared screen in front of him showed the situation outside Blue Star.
Not far from the Blue Star, the small spacecraft that had been separated from the giant spacecraft suddenly stopped in the universe.
Just when the two of them were wondering what this small spacecraft was going to do.
But after it hovered for a moment, it flickered and disappeared again.
A few seconds later, the small spacecraft appeared outside the lunar base.
"Sir, it's coming..."
Uncle Da was about to say something when his eyes suddenly widened.
"What's wrong?!" Zhao Yu was frightened and quickly asked about the situation.
"It's gone again!"
Uncle Da stood up and said: "But it left something behind. Sir, please wait a moment. I will send the robot over to see what it is..."
The surveillance footage outside the base appears.
A ten-meter-sized, square iron lump is placed at the entrance of the base.
Soon, dozens of Xiaotians appeared, approached the vicinity of Tiediaoda, and began to check.
Xiao Tian circled around a few times, and slowly touched it without finding anything unusual.
The moment Xiaotian's robotic arm came into contact with Tie Qiaoda, a flow of information suddenly invaded and was received by Uncle Da.
"Sir, it left us a message..."
"What did you say?!"
Uncle Da couldn't hide the shock in his eyes. He waved his hand and displayed the information left by the other party in the form of a projection.
This is a video shot from a bird's-eye view. The picture shows a strange universe with only dozens of galaxies.
Countless spaceships are parked in one place and rotating, like outside the vortex of the gate of time and space.
Immediately afterwards, a diamond-shaped object passed through the vortex and appeared in the universe.
"What is this place?!"
This video is very clear, and every corner of the universe can be clearly displayed.
After Uncle Da pauses, he can zoom in on any point he chooses countless times.
Aim at a planet and zoom in, and you can actually see the conditions inside the planet directly.
With extreme magnification, you can even see the shape of a grain of sand.
But what shocked Zhao Yu was that this planet is full of high-tech products that appear in science fiction movies.
"This universe is very strange. There seems to be a boundary. There are 35 galaxies in total, a total of 188 natural planets and 53 artificial planets..."
Uncle Da explained from the side: "There are about 9 trillion intelligent beings on these planets..."
"In the universe, there are probably more than 300 million warships, all facing that vortex, and when they see that diamond-shaped object, they feel as if they are facing a formidable enemy..."
Zhao Yu nodded and let the video continue playing.
The next second, he was completely shocked.
That rhombus-shaped object spread throughout the entire universe in the blink of an eye. As if it could be teleported and copied, it could easily appear hundreds of millions or even billions of kilometers away, as if they were supposed to be there.<
/p>
Then, with his mouth open the whole time, Zhao Yu watched the rhombus-shaped objects connected together, watching all the battleships in this universe disintegrate, and hundreds of millions of intelligent creatures turning into ice sculptures.
"Not only that, all high-tech products in this universe were turned into various minerals in a very short period of time..."
Uncle Da had already browsed the video in advance, and explained it appropriately while Zhao Yu was watching it.
"According to judgment, the civilization level in this universe may be as high as 3.99..."
"But that rhombus-shaped object easily destroyed everything they had..."
Uncle Da continued: "According to the information, the civilization that emitted the rhombus-shaped object is a fourth-level civilization, coming from inside the galactic center..."
"They plan to establish a galactic empire and unify the entire galaxy..."
"This time they came to the solar system precisely because they discovered that intelligent life was born here and came to distribute tokens..."
Uncle Da quickly showed a photo of the iron bump outside the base gate and explained: "There is a device inside that can enter the quantum world, and there is also a token anchor that is used to shuttle through the quantum world and arrive at what they said
Reporting location..."
"Galactic Empire..."
Zhao Yu was a little shocked that the fourth-level civilization actually wanted to unify the Milky Way.
He quickly said: "Aren't they going to destroy us?"
Uncle Da shook his head and said: "According to what was mentioned in the message, they said they require us to enter the quantum world in three days, use the token anchor point to shuttle to the reporting point, and register our civilization..."
"He also said that if we fail to register as required, we will not be protected by the Galactic Empire, and all races belonging to our civilization will become materials..."
"What is material?!"
"I don't know, they didn't say it, but it shouldn't be a good thing..."
Uncle Da shook his head and asked: "Sir, what should we do?!"
He hesitated for a moment and then said: "The message mentioned that the token anchor can only be used by one person. It is required that the highest authority of our civilization be allowed in, otherwise the consequences will be borne at your own risk..."
"Level 4 civilization wants to unify the galaxy..."
Zhao Yu didn't expect that the law of the cosmic forest that had prevailed for so long would be ended like this?
Is he going to witness history?!
"Sir, how about letting Colonel Chu pass?" Uncle Da said with some worry.
Zhao Yu was startled for a moment, shook his head and said: "It's too late. It will take more than twenty days for Colonel Chu to come back. The Galaxy Empire requires us to go there in three days..."
At this moment, the only living person on the Blue Star and the Moon is Zhao Yu. The other humans are in the Bell Comet 8 billion kilometers away and will not be able to return in a short time.
As for Uncle Da and others, although they have high intelligence and even independent consciousness, they are still unable to enter the quantum world for unknown reasons.
It's like the quantum world has some kind of restrictions, and only flesh-and-blood creatures like Zhao Yu and the others can enter.
"Are you going then?!"
"Must go!"
Zhao Yu solemnly said: "Whether it's the two-thousand-kilometer spaceship that just appeared or the content mentioned in this message, it can prove that this Galactic Empire is very powerful. If you don't obey them..." p>
Zhao Yu shuddered when he thought of the situation where the third-level peak civilization, which was a hundred times or a thousand times more powerful than them, with a population of nine trillion, was destroyed in an instant.
"The key is, they know our location!"
Before figuring out how the other party found them, Zhao Yu understood that the only way in front of him was to be obedient.
"Take out that set of equipment. In three days, I will enter the quantum world..."
