Since the initial data is not yet complete, Xiao Yu still doesn't know how much matter and space he has to eject before the speed of his small universe will be reduced to zero and eventually merge with the big universe. But thinking about it, the volume of this planet is about 20 billion cubic meters.
A dwarf planet of about kilometers should be enough.
Under Xiao Yu's control, billions of engineering robots were placed on this dwarf planet, working busy day and night. This number only includes humanoid engineering robots, and does not include other types of engineering robots.
Large machinery, as well as more than two million rural-class spacecraft responsible for transportation tasks. Space 3 and Space 4 have been built, and together with Space 2, they were transported to the vicinity of the dwarf planet by Xiao Yu. This will save money
A lot of time, greatly speeding up the project progress.
As a result, in this lonely star system, such a strange scene happened. Countless robots and mechanical equipment were busy on the planet like ants. They were like biting bread, and they ferociously came from the planet.
Pieces of debris were torn off from the airship. These debris were quickly transported away by the spacecraft, placed at designated locations, and then ejected out together with the space itself by space weapons.
A section of lines, when combined into a circle, has the largest area. Similarly, when a surface is curled into a sphere, its volume is the largest. In order to project the most matter with the smallest power, Xiao Yu also
These transported materials have undergone preliminary processing. The specific method is that after gathering materials of a certain mass and volume, a gravity bomb will be placed in the materials and then detonated.
After the gravity bomb is detonated, under the action of gravity, these messy materials will be aggregated into an approximately standard sphere. Then, before the effect of the gravity bomb is lost, the space weapon will tear this piece of space apart.
.Throw it out directly.
Every time space debris is ejected, hundreds of millions or billions of tons of material will be ejected. After the project lasted for three months, the diameter of the planet has been reduced by a full 500 kilometers.
This means that it has lost a considerable amount of mass. But its kinetic energy is still there, and it is still orbiting the white dwarf star at its original speed. The reduction in mass means that the gravity is reduced, and the gravitational pull on it is reduced.
, so its orbit expanded outward by hundreds of thousands of kilometers.
The calculation of the orbit of the small universe has been ongoing. The shrinking number shows that the distance between the small universe and the large universe is constantly decreasing. Success lies ahead, and Xiao Yu is moving forward step by step.
This is a crazy project. In the more than ten thousand years since he left the earth, Xiao Yu has destroyed more than one planet. For example, blowing it up directly, or pushing it directly into the star. But such a crazy way of destruction
This is Xiao Yu's first time. Moreover, Xiao Yu estimates that there will be no existence in the universe that would adopt this method.
To completely dismember a planet is such a huge and crazy thing!
Fortunately, this planet is a dwarf planet and there is no liquid lava inside it. The extremely low temperature also makes it impossible for liquid water or other liquid substances to exist, which saves Xiao Yu a lot of trouble.
During the project, Xiao Yu also took the opportunity to study the geological composition of the planet in detail and improved his theory of planetary evolution a lot.
Time passed bit by bit. Everything was as Xiao Yu expected. The small universe is getting closer and closer to the big universe, and the spatial stability of this small universe is getting lower and lower. This means that the efficiency of space weapons has increased.
, so far, a space weapon can eject dozens of cubic kilometers of material at a time.
A year has passed quietly, and the appearance of this small universe has been completely changed by Xiao Yu. The fragments of the battleships that can be seen everywhere have been recovered by Xiao Yu, and the valuable fragments have been properly kept by Xiao Yu.
The ones that are useful are mixed with the materials from the dwarf planets and ejected directly.
So far, the diameter of this dwarf planet has been reduced to less than 200 kilometers, making it a veritable asteroid. Due to its own pressure, although liquid lava cannot be formed inside it, ordinary temperature rises
It can still be achieved at higher temperatures. In fact, during the excavation process of the robot, the closer to the core, the higher the temperature becomes, rising to nearly 300 degrees Celsius now.
There is another point. Also due to its own pressure, the material density at the core of the planet will be very high. Although it has not reached that exaggerated level, the obstacles to Xiao Yu's project progress are still very obvious.
The working environment began to become harsh, and the progress of the project was seriously hindered. Xiao Yu thought for a moment, and simply sent out special engineering robots to drill several hundreds of kilometers deep into the core of the remaining planet.
The large hole buried a large-yield nuclear bomb in it, and then detonated it directly. With a flash of dazzling light, the last remaining material of the planet was blown to pieces.
The planet finally completely died in Xiao Yu's hands, not even the bones were left.
After blowing the planet into pieces, the progress of the project went much smoother, but Xiao Yu gradually became worried. Now Xiao Yu has a lot of experimental data and can basically calculate that he needs to slow down this small universe to a standstill.
state, approximately how much material needs to be ejected.
The calculation results seem to verify Luca-3's guess. According to Xiao Yu's calculations, to make this small universe completely stationary, the mass that needs to be ejected is about the same as the mass of this dwarf planet.
This is basically not a coincidence. This fact explains the arrangements of the Tolor civilization from the side. Xiao Yu also began to believe that this dwarf planet was really left by the Tolor civilization, specifically for the dwarves who entered later.
Civilizations use it to slow down this small universe.
But this calculation result is only approximate. Xiao Yu is currently unable to obtain too precise data. In other words, to reduce the speed of this small universe to zero, the actual mass required may be slightly different from this, and may be shorter than this one.
The overall mass of the planet is greater, or it may be a little smaller than the overall mass of this dwarf planet.
If it is smaller, then there is no problem, but... what if the required mass is more than the mass of this planet?
Don't forget, even if the error of this result is only 0.1% - you must know that it has been hundreds of thousands of years since the Trol civilization left this relic. Within these hundreds of thousands of years, everything happened
An error as small as 0.1% does not seem to be unusual.
But if you do some calculations, you will find that things are not that simple.
The total mass of this dwarf planet is about two trillion tons. The mass of 0.1% is two trillion tons. Where will Xiao Yu find such a large amount of mass?
There is no doubt that the white dwarf star will have a lot of mass, but with Xiao Yu's current level of technology, he does not have the strength to take action on a white dwarf star.
In addition to this white dwarf star, there are also a large number of battleship fragments in this small universe, but their total mass does not exceed one billion tons at most, so they do not play a big role.
When there are no foreign objects to borrow, Xiao Yu can only borrow his own things. But one thing must be known, a national-level spacecraft only has a mass of several hundred million tons. If it really has 0.1%
If the error is , even if all Xiao Yu's spaceships are used to fill this gap, it will not be enough.
"If things really develop into this situation, we have no choice but to operate on the corpse of this fourth-level alien beast." Xiao Yu secretly thought, "The total mass of the corpse of this fourth-level alien beast is almost 10,000.
It looks like a gigaton. But I plan to use this thing to build a spaceship... Hey, I hope things won't progress to this point."
"Let's eject the rest of the planet first." Xiao Yu sighed secretly, cheered up, and began to finish the work.
In the current small universe, the dwarf planet has completely disappeared, and its huge body is only left with some asteroid fragments with a diameter of only ten kilometers. Xiao Yu has no intention of letting go of its body. The space
The weapon was activated and these things were quickly thrown out.
After completely dismembering the dwarf planet and throwing it all out, Xiao Yu once again conducted a general cleaning in this small universe. All the damaged parts, battleship fragments with no recycling value, and all the garbage were gathered together.
There were about 300 million tons - all of them were ejected at once.
Everything has been done so far. Xiao Yu began to wait quietly.
At this moment, the small universe is overlapping with the big universe. To verify whether the small universe has offset all the kinetic energy by Xiao Yu, there is a very simple way, that is to see if the small universe will leave the big universe again. If it leaves
, that proves that the small universe still has kinetic energy, and its work is not finished yet. If the small universe no longer leaves the big universe, it proves that it has succeeded. In the next time, it only needs to wait quietly, at most
Within a month, the small universe will be assimilated into the large universe.
The answer to verifying this question is also very simple, that is, continuously emitting low-power space cracks and indirectly calculating the strength of the cracks.
The Space One on board the China spacecraft was in this situation. Tiny space cracks flashed in front of it one after another, and then disappeared quickly... (To be continued, please search Piao Tian Literature, the novel is better updated.
