Chapter 449 Black Hole Web

If all the remaining fuel of Han Yang is used to slow down, the speed of the spacecraft can be reduced from 99% of the speed of light to about 20% of the speed of light, which is about 60,000 kilometers per second.

The fuel was not enough, but Han Yang still did not give up using it. Instead, he continued to use it to adjust the course of the spacecraft. Even though the spacecraft was already aimed at the Canis Major dwarf galaxy, even if no further adjustments were made, the spacecraft would definitely enter the Canis Major dwarf galaxy.

Moreover, this orbit adjustment is not a one-time adjustment, but a little adjustment at a time, or even a slight adjustment every few years or even a dozen years.

Under this circumstance, Han Yang's last remaining spacecraft is still constantly approaching this galaxy.

Time passed slowly, and thousands of years passed in the blink of an eye. At this time, Han Yang noticed that the long-distance communication had returned from being unavailable to being available. Although the communication rate and quality were still very low, just like when he was far away from the Milky Way.

This means that the density of matter around him is slowly increasing. This is obviously because he is getting closer and closer to the Canis Major dwarf galaxy.

Of course, Han Yang knows that at this moment, super-long-distance communication is only available within the range of the Canis Major dwarf galaxy. It is still impossible to communicate with the Milky Way. The reason is also very simple. The intergalactic space between the Canis Major dwarf galaxy and the Milky Way is too vast. It is like a wall that blocks the communication between the two galaxies.

At this moment, Han Yang's heart is full of sighs.

The long time has passed. His journey has finally reached the final stage.

Time is still passing quietly, and Han Yang still maintains the operation of slightly adjusting the course every few years or more than ten years. The little remaining fuel continues to be slowly consumed under this situation.

There is a star in front, not far from Han Yang. According to the current course calculation, he will eventually pass by it only 60 light years away.

It is a huge red giant. It is already at the end of its life and it is extremely expanded, and its radius has even expanded to 200 million kilometers.

If it is placed in the position of the sun, it can even swallow the earth.

Han Yang saw that around the huge star, there are two gas giant planets larger than Jupiter rotating around it and bearing its scorch. In the middle of the two large planets, there is an asteroid belt surrounding it like a belt.

Although it has not been observed in detail, Han Yang can still conclude from a preliminary estimate that there are at least 100 dwarf planets larger than Ceres in the asteroid belt. There are endless materials in it that can be converted into endless energy.

But unfortunately, Han Yang cannot reach that star system. Even if he tries to adjust the orbit to point to that star, he does not have enough fuel to slow down and cannot stay there.

But it doesn't matter, Han Yang has no intention of going there.

According to Han Yang's observation, in his direction, this star is the outermost star in the Canis Major dwarf galaxy.

Here, like the edge of the Milky Way, the stars are sparse. But one unquestionable reality is that even if it is at the edge, at least, he has truly arrived at the Canis Major dwarf galaxy and has truly entered the interior of this dwarf galaxy.

The long journey of more than 20,000 years is about to end.

Han Yang passed this star without any regrets and continued to move forward.

The number of stars visible in the sky has increased again. Even with a telescope equivalent to the level of the naked eye, Han Yang can see about a thousand stars in the night sky.

They are dotted in the starry sky, like pieces of gems. The dark and empty starry sky is finally no longer lonely at this moment, and finally has a little more color.

Han Yang mobilized all his observation equipment and began to truly observe this extragalactic galaxy closest to the Milky Way.

The diameter of the Canis Major dwarf galaxy is only about 5,000 light years, only one twentieth of the Milky Way.

The number of stars inside it is only about 1 billion, about one 300th of the Milky Way. Moreover, most of the stars that make up this galaxy are red giants.

Red giants are old stars. The reason why this galaxy is dominated by old stars is that the rate of new star birth in this galaxy is very low.

Because the birth of stars depends on interstellar molecular clouds, interstellar dust clouds collapse, and a large amount of matter gathers to gather enough mass and light up stars.

And because of the huge mass of the Milky Way, the interstellar dust clouds in the Canis Major Dwarf Galaxy are plundered by the Milky Way in large quantities and continue to flow into the Milky Way.

This even forms a "star stream" connecting the two galaxies.

It is like a river, constantly starting from the Canis Major Dwarf Galaxy, crossing a distance of tens of thousands of light years, spending tens of millions or hundreds of millions of years, and constantly rushing to the Milky Way.

Even Han Yang is heading to the Canis Major Dwarf Galaxy at this moment, just going upstream against this stardust river.

Of course, the so-called "stardust river" is just a figurative statement. In fact, the material density of this star stream is also very low, even comparable to the ultra-pure vacuum created by Han Yang in the laboratory, and it cannot even support the material density required for long-distance communication.

It is only because this river is too wide and lasts long enough that it is able to transport enough matter from the Canis Major dwarf galaxy to the Milky Way.

After billions of years, tens of billions of years, the interstellar dust clouds in the Canis Major dwarf galaxy became fewer and fewer, new stars were born fewer and fewer, and the existing stars continued to age, and finally became what it is now.

In fact, there is more than just the Canis Major dwarf galaxy. There are dozens of satellite galaxies like the Canis Major dwarf galaxy around the Milky Way, and at least half of them are constantly being plundered by the Milky Way.

There are dozens of such star streams around the Milky Way.

Even more, Han Yang believes that billions or even billions of years ago, there were more satellite galaxies around the Milky Way than there are now.

Why are there fewer now?

When in the Milky Way, the study of some special star clusters revealed the answer.

Han Yang knew that some special star clusters inside the Milky Way were not actually formed in the Milky Way. They were formed outside the Milky Way, and they were originally an independent and complete extragalactic galaxy.

It was just because of the huge gravitational force of the Milky Way that the galaxies they formed were directly swallowed up by the Milky Way and became part of the Milky Way. Therefore, they will show various differences inside the Milky Way, such as special orbits and speeds, special orbiting directions, special metal abundances, etc.

This is a gravitational battle at the galaxy level. In this space, the Milky Way is undoubtedly the dominant and the king.

Han Yang's spacecraft is still moving at 99% of the speed of light. After sailing for hundreds of years, the star density finally increased, and the number of stars visible to the naked eye in the sky gradually increased, reaching about 2,000 stars visible to the naked eye.

Moreover, the distribution of stars has changed from only gathering in one area of ​​the sky to occupying the entire celestial sphere.

It is worth noting that at this distance, the Milky Way is also clearly visible. It's just that it is no longer like a river seen on the earth, but has become a pouring roulette shape.

It is very eye-catching and occupies a large area of ​​the sky.

In addition, there is a much smaller and dimmer existence next to it, but it is also disc-shaped.

That is the Andromeda Galaxy.

There are also galaxies that are dimmer and smaller, but also visible to the naked eye.

That is the Triangulum Galaxy.

The sky is dotted with stars, galaxies, stars, galaxies, stardust... all kinds of existence, making the sky finally colorful.

Looking at this magnificent sky, Han Yang's heart is full of emotion.

The plan is the next step.

At this moment, the speed of the spacecraft is still maintained at about 99% of the speed of light. And all the available fuel Han Yang has left at this moment is only enough to reduce the speed of the spacecraft to about 45% of the speed of light, that is, about 135,000 kilometers per second.

This speed is still too high. If he maintains this speed, he will directly pass through the Canis Major Dwarf Galaxy and step into the vast starry sky again, until the last bit of energy is exhausted and his brain is completely dead.

Moreover, at such a high speed, Han Yang has no way to obtain mass from the outside world.

There must be other ways to do it.

At this moment, the situation seems to be in a desperate situation, but Han Yang is not panicked at all. He has already planned everything.

Before, he would rather spend the insufficient energy to correct the course of the spacecraft, which is part of this plan.

The small spaceship was still moving forward at a high speed, and Han Yang began to use the remaining fuel to slow down. Moreover, while slowing down, he adjusted his course and flew towards a certain direction of the Canis Major dwarf galaxy.

Thousands of years ago, when Han Yang was thousands of light years away from the Canis Major dwarf galaxy, Han Yang had already discovered that there was a very special celestial body in this place.

It was pitch black here, and no stars could be seen. But around it, many stars were rotating around it. Moreover, around it, Han Yang could even see two identical stars.

Completely, completely identical. The two stars not only had the same mass, volume, metallicity, and temperature, but also the same color and stellar activity.

Is it possible for two identical stars to be born in the universe? Han Yang believed that the probability was there, but it was too low, so low that it had no practical significance at all.

In other words, it was basically impossible for two identical stars to exist in the universe.

So why did it appear here?

The reason is very simple. It is not that two identical stars really appeared, but that the same star has two "images" because of gravitational lensing.

Why does gravitational lensing appear? Obviously, there is a massive celestial body between him and the star.

Invisible massive celestial body, surrounding stars revolving around it, gravitational lensing...

Through these extremely obvious phenomena, Han Yang immediately determined that there was a black hole hidden there.

A black hole with a mass of 16,000 times the mass of the sun, but a radius of only about 47,000 kilometers.

At this moment, Han Yang rushed straight towards the black hole.

As the distance got closer, more details about the black hole entered Han Yang's detector.

Han Yang found that this was a black hole that could be considered dormant.

The so-called dormant period is a period when there is not much matter around the black hole, the rate of swallowing matter is slow, and the external radiation is low. However, according to Han Yang's observation, there is a star close to it. According to the current orbit calculation, it will be close enough to it in about 100 million years.

At that time, the star will be completely torn apart. In the millions of years that may be long, all the mass of the star will be bitten and swallowed by the black hole. The whole black hole will be completely activated and become an extremely bright star.

But that will be a matter of 100 million years later and has nothing to do with Han Yang at this moment. At least at this moment, only some thin interstellar gas has fallen into the black hole. The friction between them is weak and it cannot radiate much energy outward. The environment is not bad. Even if Han Yang approaches, it will not be affected much.

At this moment, the speed of the spacecraft has dropped to about 146,000 kilometers per second. He still has a small amount of fuel left, but he has not slowed down.

This part of the fuel will be used in some subsequent plans that are extremely critical and can directly determine Han Yang's fate.

During the precise orbit adjustment, Han Yang rushed to the orbit of about 50,000 kilometers next to the black hole at an acute angle by inertia.

Then, the spacecraft, which Han Yang no longer had enough fuel to slow down, was bound by the gravity of the massive black hole.

The spacecraft could no longer fly forward, and instead began to revolve around it at a speed of 146,000 kilometers per second under the gravitational field of the black hole. Every 4 seconds, the spacecraft would revolve around the black hole.

But that was only the time of the outside world. Because of the extremely high speed at this moment and the huge gravitational field of the black hole, the relationship between time and space has been changed.

In Han Yang's view, it actually took him less than a microsecond to circle the black hole.

Han Yang immediately began to operate the relevant equipment to check and confirm the current orbit. After confirming it several times in a row, Han Yang finally breathed a sigh of relief.

He knew that he had finally truly stayed in the Canis Major dwarf galaxy at this moment, and he no longer had to worry about passing directly through this galaxy.

The gravity of the black hole is like a huge, elastic net, which forcibly pulled the "arrow" to a stop.

The situation is temporarily stable. At this moment, Han Yang finally has some thoughts and looks at the surrounding environment.

What is presented in front of Han Yang at this moment is a magnificent and wonderful scene that is indescribable. (End of this chapter)
