Super Battleship Reborn

The two black holes at the core of the Andromeda galaxy eventually merged into a larger black hole. This is an unchangeable fact, and even Xiao Yu has no way to change this. This is an action between stars with hundreds of millions of times the mass of the sun. Xiao Yu may spend a long time and a lot of energy to destroy these two black holes, but he has no ability to prevent their final fusion.

Two stars colliding will have a high probability of merging into a larger star. During this process, an extremely violent burst of energy will occur. When two white dwarfs collide, depending on the conditions, a larger star will be formed. Heavy white dwarfs either explode or form neutron stars, but in the process there will still be a huge burst of energy. As for the collision of two neutron stars, there is no need to say more. The violent energy burst caused by the collision of neutron stars is the most violent way of energy explosion in the universe, and it is one of the sources of gamma-ray bursts.

It stands to reason that when two black holes collide, there will be a more violent burst of energy, but this is not the case. The most critical point is that black holes are only allowed to enter and not allowed to exit. Except for the loss of mass and information through negative matter particles and information storms, black holes do not allow any other matter or energy to escape from their bodies. This means that the process of the two black holes merging with each other is smooth, and they will merge into one body with basically no loss of energy or matter.

The reason why I say basically rather than absolutely is because under special circumstances, there will still be unexpected situations. Just like now, when these two black holes are surrounded by a large amount of matter.

The extreme gravitational pull of a black hole accelerates matter revolving around itself to extremely high speeds, forming an accretion disk. In this process, a huge amount of energy will be ejected along the two poles of the black hole, even millions of light-years away. This is one of the most spectacular sights in the universe, the black hole jet.

During the fusion process of these two black holes. The black holes themselves will not lose any energy or mass, but the dust clouds revolving around them at extremely high speeds are different. During the collision process, they will collide at extremely high energy levels and burst into infinite explosions. With unparalleled intense energy, it is stronger than neutron star collisions and supernova explosions.

At that time. The entire core of Andromeda will brighten, even reaching a level that exceeds the brightness of stars in the entire galaxy. By that time, the brightness of the Andromeda Galaxy will also increase many times when viewed from within the Milky Way. It even reached the level of seeing the brightness of Jupiter from the earth in the earth era.

If the earth still exists, then at that time, there will be another beautiful scenery in the night sky of the earth.

This is the river system collision. Billions of years from now, the collision of the Milky Way and Andromeda will recreate the scene. The difference is. At that time, the burst of energy from the core of the galaxy will be more intense. After all, the black hole at the core of the Milky Way is much more massive than the smaller of the two black holes.

The collision of galaxies will trigger a new wave of star formation,

At that time, the Milky Way-Andromeda galaxy will become a starburst galaxy, and the birth of a large number of new stars will completely change the appearance of this new galaxy. Unfortunately, that will be tens of billions of years later. . Xiao Yu thought silently. At that time, I didn't know whether it existed or not. I don't know if I have a chance to see this scene.

Simply put, a starburst galaxy is a river system with a large number of new stars born. The reason for this is that the collision of the river systems will disturb a large number of gas and dust clouds in the two river systems. The gas and dust clouds will condense and aggregate with each other. New stars are born.

Xiao Yu stayed at the core of the Andromeda galaxy for decades. In the past few decades, Xiao Yu has observed the operation data of various stars and gas flows here in detail, and further improved his theory of the evolution of the river system.

If there are no special circumstances, Xiao Yu will stay here for a longer time, but an unexpected event broke Xiao Yu's plan.

Through heavy interstellar gas, bright stars and long-distance barriers, Xiao Yu observed that at this moment, a supernova explosion occurred in a distant galaxy, and the two poles of this supernova explosion happened to be facing Xiao Yu now direction. Therefore, in Xiao Yu's view, the exploding supernova's brightness reached the brightness of the entire river system in an instant, as if a light suddenly lit up in a dark room.

Supernova explosions are very common. Although they only happen when regular stars die, thanks to the huge star base, if you search carefully, you can always find several explosions every day in the universe. But there was something unusual about this supernova explosion.

After all, it came from his hometown, the changes in the stars in the Milky Way, so Xiao Yu recorded all kinds of data of this supernova explosion in detail, and then seemed to subconsciously, Xiao Yu compared the data of this supernova explosion with his own database. A comparison of many supernova explosion data stored in .

Based on this comparison, Xiao Yu was terrified by the conclusion he drew. Xiao Yu rechecked the comparison results somewhat inconceivably, but the final conclusion was still the same.

Xiao Yu became confused in his heart. In this case, Xiao Yu didn't know whether it was a coincidence or his own observation error, or... this kind of situation really happened in the Milky Way.

What Xiao Yu observed was a very ordinary supernova explosion, but in terms of time, it was definitely not ordinary. When he was in the Milky Way, Xiao Yu had detected the wreckage of this supernova explosion, and had sent a probe to this place. That is seen from the earth, in the direction of the Camelopard constellation, about 9,000 light-years away from the earth.

Yes, although Xiao Yu has just seen the light of this supernova explosion, when Xiao Yu was still in the Milky Way, Xiao Yu had already reached the wreckage of this supernova explosion and explored it.

This is an incredible thing, and it is illogical, but the data obtained by Xiao Yu's detection clearly told Xiao Yu that the supernova explosion he observed this time was the one he had explored before.

What's going on here? Xiao Yu thought incredulously, I've already explored its wreckage, why here, I saw the image of it exploding again?

In fact, according to the existing theory, it is not impossible for this to happen, the main reason is the impact of the super-light travel technology. For example, when Xiao Yu was in the Milky Way, a supernova explosion occurred 100,000 years ago and left behind a wreckage. Xiao Yu explored there—at this time, carrying the supernova explosion The light has already advanced a distance of 100,000 light-years. At this time, Xiao Yu spent 2.4 million years and traveled a distance of 2.5 million light-years to reach the Andromeda galaxy. , Xiao Yu will arrive at the same place with the light rays carrying the supernova explosion.

In this case, it will happen that Xiao Yu first explores the wreckage of the supernova explosion, and then sees the image of the supernova explosion. There is nothing surprising about this matter, but the situation Xiao Yu is experiencing now is not like this. The most important point of contradiction is that the time point of the supernova explosion that Xiao Yu saw did not match.

Xiao Yu once conducted a very detailed observation of the wreckage, and concluded that the supernova explosion occurred five million years ago. In this way, the light carrying the supernova explosion had already reached the Andromeda galaxy, and it had already calmed down if viewed from the Andromeda galaxy, but now, in the Andromeda galaxy, Xiao Yu once again Saw this scene.

This is an unexplainable contradiction. The possibility of two such similar supernova explosions is infinitely close to zero, but apart from this explanation, Xiao Yu really cannot explain this incident.

After observing the image of this supernova explosion, Xiao Yu paid more attention to the Milky Way. Gradually, more and more shocking and inexplicable incidents appeared in front of Xiao Yu one by one.

Xiao Yu began to observe several benchmark stars and neutron stars in the Milky Way, and came to the conclusion that the positions of these stars at this moment are completely different from the positions he calculated. They should be 2.5 million years ago Be in the position you observe at this moment, not the present.

In the following decades, Xiao Yu observed more things that should only exist in history. For example, several gamma ray bursts, several supernova explosions...

All of this is like history repeating itself, and time is turning back. In that distant river system millions of light-years away, something mysterious and unpredictable seems to be happening.

When Xiao Yu saw the existence of another planet, Xiao Yu knew that he had to go to the Milky Way. The incident this time was too weird, and I had to figure out what happened in the Milky Way. Only after clarifying these things, can I start my subsequent space travel with peace of mind.

After all, it was his hometown, and Xiao Yu would never leave if he didn't find out what happened there.

Xiao Yu saw the earth. That's right, the earth that had been destroyed long ago appeared in Xiao Yu's eyes again at this moment, and it was revolving around the sun in a somewhat strange orbit for Xiao Yu at this moment. And the solar system that Xiao Yu saw also had a huge deviation from the position he should have calculated. (to be continued..)
