Super Battleship Reborn

Xiao Yu at this moment is still in the long process of searching. Xiao Yu didn't have a clear idea of ​​where these five-level civilizations went. Because these fifth-level civilizations walked very cleanly, they did not leave any information that could indicate their whereabouts.

Xiao Yu faintly felt a little bit of conspiracy, but couldn't get more information.

So Xiao Yu could only continue searching, hoping to find some clues in the rest of the civilization's residences. Xiao Yu can only do this. In the vast sea of ​​stars and the boundless universe, it is really too easy to hide, but it is really too difficult to find a specific object.

After leaving the station of the Booth civilization star system, Xiao Yu embarked on the road to the Lyra civilization station. This is another voyage, a long journey of more than 4,600 light years, even at Xiao Yu's speed, it would take almost a hundred years to arrive.

But this time the journey was not peaceful. When the voyage was halfway through, Xiao Yu encountered an unexpected event, that is, a supernova exploded.

The supernova exploded more than 3,000 light-years away from Xiao Yu, and the whole thing exploded into pieces, leaving no white dwarf, no neutron star, and no black hole. All its matter was completely thrown into space in this violent explosion, turning into a continuously spreading planetary nebula.

This is a very rare cosmic spectacle, which is an unstable pair supernova explosion.

The distance of more than three thousand light years, if it is an ordinary supernova explosion, Xiao Yu can actually ignore it. After all, this distance is too far away. And Xiao Yu's current technology has developed to a certain level. At this distance, resisting the attack of explosive energy is nothing to Xiao Yu.

But unstable pairs of supernova explosions are not ordinary supernova explosions. The energy it releases is too strong. The energy that is so strong that it erupts can still affect Xiao Yu's fleet after a long-distance attack of more than 3,000 light years. There is no way, in order to avoid unexpected losses, Xiao Yu can only temporarily separate the fleet from the curvature space, put the planetary battle star in front, and park all the battleships behind the huge body of the Earth, with the help of the Earth No. That powerful defense. Withstood this disaster.

Unstable pair supernova... This is the first time I have encountered it since I entered the void of the universe. Such a thing is really too rare. Well, the data observed this time are enough for me to study for a long time.

Looking at the light spot in the distance that suddenly increased in brightness, even brighter than the entire Milky Way, Xiao Yu was secretly happy.

That's right, the unstable pair supernova has such a powerful ability. Any powerful existence will be eclipsed when the unstable pair goes supernova. Not even a river system can match it.

Pair instability is a very extreme phenomenon of supernova explosions. It can only happen on huge stars with 130 to 250 times the mass of the sun. Xiao Yu has a deep understanding of this type of supernova, in Xiao Yu's theory. The main reason for this kind of supernova explosion is that the gamma ray energy at the core of the star is too strong, and the too strong gamma ray will collide with the nucleus to produce free electrons and positrons. In this case, the giant star The pressure at the core would drop, causing the star to collapse locally. Then massive, rapid, uncontrolled nuclear combustion blows the entire star completely apart.

Be careful. Unstable pair supernovae do not leave behind any dense cores such as white dwarfs, neutron stars or black holes. Because the energy of the explosion is too violent, the entire star will be completely blown away in such an explosion, and there will be no chance to form these dense stars.

This is the biggest difference between it and ordinary supernova explosions. Although a Type Ia supernova will not leave any traces, it happened on a white dwarf, with its power and scale. Neither can be compared with unstable pair supernovae.

So it is conceivable how powerful the explosion of instability to supernovae will be. Because instability is too rare for a supernova, even Xiao Yu hasn't seen it a few times. When he was on the earth, Xiao Yu saw two things that were suspected to be the remnants of an unstable pair supernova explosion. Speaking of actually witnessing the entire explosion process, this was really the first time for Xiao Yu.

Poor, it is estimated that with this unstable pair supernova as the center, all low-level creatures within a radius of several thousand light-years will be killed. Xiao Yu sighed secretly, If you encounter such a violent supernova in the earth era If it explodes, all human beings on Earth will die, and the ecological environment of the Earth will be completely destroyed. It is really lucky that the Earth can develop into the human age. But unfortunately, the Earth was eventually destroyed.”

From this point, we can also see the danger of the universe. Because you never know what kind of crisis you will encounter in the next moment. You must know that the energy of a supernova explosion travels at the speed of light, so when you notice that the star has undergone a supernova explosion, the destructive energy released by it has also arrived at the same time, and you will be killed instantly Die, before even reacting. To prevent this kind of thing in advance, the only way is to use the tachyon detection technology of the fifth-level civilization to actively detect these stars. But there are so many stars in the universe, how can the power of a civilization monitor the situation of each star in real time? Even if it is possible to use the method of screening in advance and only monitor a few stars with the possibility of explosion, how small is the number of fifth-level civilizations in the Milky Way?

Every civilization is a legend, and every civilization has a wonderful story. Xiao Yu sighed.

After the most violent explosion energy passed, Xiao Yu continued on the journey. Although the unstable vs. supernova is exciting, it is not enough to stop Xiao Yu.

Xiao Yu can do it without paying much attention to an unstable supernova explosion, but some existences can't. Those Pegasus civilization people who escaped.

They were right in front of Xiao Yu, closer to the exploded unstable pair supernova, so they were more strongly affected. And their technology is not as advanced as Xiao Yu's. The most serious thing is that many of their fleeing fleets are not warships, but ordinary civilian or commercial and industrial spaceships. The defense of these spaceships is much worse than that of battleships.

So this sudden and indiscriminate disaster caused them huge losses. Nearly half of the spaceships and people died in this disaster, and the remaining half of the spaceships generally suffered serious damage. The engines burned out, the energy reserves were exhausted, and precision components were damaged. There are countless incidents.

During the period of fleeing, the people of this part of the Pegasus civilization have produced new leaders and various related institutions. The new government quickly assessed the current damage and carried out a series of post-disaster relief matters.

But the current situation really made him unable to be optimistic.

I have always firmly believed that any suffering is the tempering of our civilization. Our civilization will eventually be reborn from the ashes and stand at the pinnacle of the universe. I have never wavered in this belief. But now, my belief has been shaken .I was thinking, why did this series of disasters happen to our civilization? We, can we really overcome the predicament in front of us?

The new leader, who had just finished an impassioned speech and successfully aroused the fighting spirit of the surviving people, ended the speech and returned to his private residence, but the whole person became decadent. Looking at the fleet damage report in front of him, he couldn't help but burst into tears.

The reality before him was cruel. Because of the severe damage, the fleet has lost the ability to continue long-distance voyages, so the only way at present is to find a nearby planet to station. However, the Pegasus civilization does not have the power to transform the planet at this moment. The number of people is too small, the number of various mechanical equipment is too small, and there are faults in technology. The scarcity of scientists determines that within at least thousands of years, their technology Levels can only go backwards, not forwards.

Finding a planet that is suitable for their survival, or a planet that can be suitable for survival with only a very simple transformation, and then spend their main energy on cultivating future generations, developing education, and increasing the number of scientists as much as possible. This is their only chance of survival. And if they are stationed nearby, it means that in order to maintain the survival of the people, their main energy must be put on transforming the planet, and the cause of education will be delayed.

This delay, what is delayed, may be the hope of the entire civilization.

This series of blows has pushed the mind of the new leader to the brink of collapse.

After crying silently for half an hour in the empty room, he stood up, wiped away the tears on his face, tidied up his appearance, and walked out of the room. He has returned to the kind of wisdom beads in his hands, and he can't be knocked down by any difficulty.

Before he had time to give instructions to the assistant who came up, he felt a violent shaking, as if an earthquake had occurred on the spaceship. But he knew that it was impossible for an earthquake to occur on the spaceship.

What happened, go investigate and report to me immediately...

He ordered in a steady voice. Although he was also very panicked in his heart at the moment, he knew that this kind of emotion should not be shown and could not be seen by anyone.
