At this moment, it has been more than 1,300 years since Xiao Yu left the center of the Milky Way. After more than 200 years of sailing and a distance of about 8,000 light years, Xiao Yu will arrive at the edge of the Milky Way.
In fact, even here, it already belongs to the edge of the Milky Way. Here, the density of stars has further reduced, reaching an average distance of nearly twenty light years. Calculated according to the average distance from the center of the galaxy, Xiao Yu's footsteps at this moment,
It has passed the time when he was led by the semi-four-dimensional Taihao to the edge of the galaxy.
It was here that Xiao Yu began his first experiment of moving stars. Xiao Yu selected a yellow dwarf star that was in its middle age and began to make preliminary arrangements next to it.
Transporting an object with such a huge mass as a star is no longer just a matter of the size of the channel. Therefore, Xiao Yu must make the instrument in advance and arrange it on the edge of the star in advance. After making some adjustments to the space where it is located,
Only then can it be transported. The Earth spacecraft led the small universe to the side of the star, and the instruments arranged in advance began to change the space around the star as expected. The connection channel between the large and small universes has been opened, and instruments everywhere
With their cooperation, the transportation began.
For this transportation, Xiao Yu prepared for a long time and spent a lot of energy. This does not include the time consumed in the early scientific research. But the actual transportation process is really simple. It couldn't be simpler. After Xiao Yu started the transportation
After installing the instrument, the star suddenly disappeared from the visible universe. The process took no more than three minutes. It was that simple. The transfer of the star was completed, and it had already appeared in Xiao Yu's small universe.
A stable gravitational system has been formed in the small universe. Dozens of stars are running quietly and smoothly under the mutual gravitational pull and Xiao Yu's orbit adjustment instrument. If an additional star suddenly appears here,
Star, then without Xiao Yu's human intervention, this would have had disastrous consequences.
The gravity of the new star will instantly break the gravitational balance in the small universe. The final result is that dozens of stars will resume chaotic orbits again, and may even collide with each other, and then spread to other stars, changing
The orbits of the remaining stars will cause them to collide again. The final result may be that all stars are destroyed.
Of course, it is impossible for Xiao Yu to allow such a situation to happen. Xiao Yu had already made all preparations before this star entered the small universe. All the impacts it may cause are within Xiao Yu's assessment
, and were prepared in advance to welcome it. The entire process of transporting the stars was completed smoothly under Xiao Yu's control, without any disturbance.
After the star was transported away, Xiao Yu also saw a very interesting phenomenon. This star also has a planetary system. There is a planet about the size of Mars orbiting it at a distance of ten light minutes from it.
.But now, at the core of this star's orbit, this star suddenly disappeared.
Xiao Yu saw that after the star disappeared, the planet seemed to be unaware of it. It was still moving according to its original orbit. It was as if the star was still there. If this scene was filmed and played,
If it were shown to some low-level civilizations, Xiao Yu could be sure that this situation would definitely drive many physicists crazy.
Because in this system, there are no strong sources of gravity, no stars, no white dwarfs, neutron stars, and no black holes. Except for this planet, everything is nothingness. So, what is this planet orbiting?
This is a very interesting question, and it is also a seemingly contradictory, but actually very simple phenomenon stipulated by the laws of physics. Because the speed of normal navigation in the normal universe cannot exceed the speed of light, no matter it is a small planet
Whether it is a planet, a spaceship, a beam of light, or a gravitational wave, its propagation speed cannot exceed the speed of light. So if gravity is regarded as an entity, we can draw the conclusion that a gravitational wave has just
Leaving the star and launching towards the planet, and then the star disappears, the planet will still maintain its original orbit under the influence of the gravitational waves previously emitted by the star. Until this last
After the gravitational waves are transmitted to the planet and complete their own process, the planet will notice, oh, this guy who has been restraining me has disappeared, and there is no more gravitational force transmitted to me. At this time
It will change its trajectory.
The current time is the interval between the disappearance of the star and the planet's awareness of the disappearance of the star.
The distance between the two was ten light minutes, so the planet orbited a point of nothingness in the void for ten minutes. After arriving in ten minutes, Xiao Yu saw that the orbit of the planet immediately changed.
been changed.
Its previous orbit around the star can be roughly viewed as a circle. Now, when there is no longer any gravity binding it, it immediately flies out in a straight line along the tangent of the circle, until it reaches the dark
Deep in the universe.
Xiao Yu knew that it had become a wandering planet. In the endless years to come, it would continue to wander in the Milky Way. Perhaps it would be captured by a star again and become a member of that star family.
However, its elemental structure, which is very different from that of local members, will trouble the minds of intelligent creatures that may appear in that galaxy, because they will have to think about a question: "Why do planets in the same star system have different elemental structures?"
Is there such a huge difference?"
Thinking of these things, Xiao Yu felt a little better. After transporting this star to his own small universe, Xiao Yu embarked on the journey again, heading to the next star, and then continued to collect it.
Entering his own small universe. When Xiao Yu's fleet reaches a star, that star will disappear from the visible universe. It seems that Xiao Yu is a terrifying star devourer.
In this way, Xiao Yu stocked up on suitable stars as he walked, stopping and stopping along the way, and finally reached the edge of the Milky Way galaxy after about two hundred years.
Here is the real edge of the Milky Way. Here, it is about 100,000 light-years away from the center of the Milky Way. At this moment, the aging, huge, slow-moving red giant that appears in front of Xiao Yu is the approximately circular shape of the Milky Way.
The star farthest from the center of the Milky Way above the radius of the Milky Way. This means that after passing this star, Xiao Yu will no longer be able to contact any stellar quasars before reaching the Large Magellanic Cloud.
In fact, the material here is not too thin. Xiao Yu can observe that a lot of interstellar dust gathers here. Because this is the place where the Magellanic Stream emitted by the Large Magellanic Cloud merges into the Milky Way. In fact, it is nearby
The border of hundreds to thousands of light years can be regarded as the convergence point of the Magellanic Stream. The Magellanic Stream is like a huge river, rushing all the time, injecting a huge amount of material from the Large Magellanic Cloud
Come to the galaxy.
The galactic center is completely invisible from here, unless you use a very high-precision optical telescope. This is because the distance from the galactic center is too far at this moment, and there are too many obstructions in the middle. Even if
The central black hole is so powerful that the rays it releases cannot pass through so many obstacles and reach Xiao Yu. But Xiao Yu knows that it is still in control of this place. Because even an aging red star at the edge of the galaxy
The big stars are still orbiting around it.
"This is the outermost boundary of the Milky Way. After crossing this star, I have truly left the Milky Way. Although it is still far away from escaping the gravitational influence of the Milky Way - that would require a long journey of millions of light years.
Journey. Even the Large Magellanic Cloud, an extragalactic galaxy, is only a satellite galaxy of the Milky Way. It is still affected by the gravitational influence of the Milky Way and revolves around the Milky Way. From the first time it left the solar system to the first time it leaves the Milky Way, in a hurry,
Nearly 40,000 years have passed."
Unknowingly, 40,000 years have passed since he first entered the universe. This incident made Xiao Yu sigh with emotion. The sea has changed, the world has changed, and 40,000 years have passed by in a hurry.
"I don't know what the situation is in the solar system now. I haven't returned to the solar system for 40,000 years... After I have free time, time, and no worries, maybe I really should return to the solar system.
Go and take a look. It took 40,000 years for me to grow up to the point where I am strong enough to be ranked in the top ten in the galaxy. If you include my companion ghost clan, I am strong enough to be ranked in the top five. But my heart has never changed. Earth
It is my hometown, the solar system is my hometown, and the Milky Way is also my hometown. This is the brand I carry and will never change. The separation is for a better reunion, and all mysteries will eventually be found by me.
As a result, the name Shenzhou Civilization will eventually resound throughout the universe. So, farewell, Galaxy, I will come back again in the future."
"Goodbye, Milky Way." After saying goodbye again in the direction of the center of the Milky Way, Xiao Yu controlled his huge fleet, left the Milky Way without hesitation, and embarked on a vast journey.
What greets Xiao Yu ahead will be the mysterious unknown of another river system, and a distant journey that is 100,000 light years long without any supplies. What lies ahead may be hope, or it may be destruction.
