Chapter five hundred and sixty-two unstable pair supernova
At this moment, Xiao Yu is still in the process of a long search. Xiao Yu does not have a clear idea of where these fifth-level civilizations have gone. Because these fifth-level civilizations left very cleanly, they did not leave anything behind.
Information indicating where you are going.
Xiao Yu faintly sensed a hint of conspiracy, but was unable to obtain any more information.
So Xiao Yu could only continue to search, hoping to find some clues in the locations of other civilizations. Xiao Yu could only do this. In the vast sea of stars and the boundless universe, it is really too easy to hide. If you want to find a specific object,
It's really too difficult.
After leaving the station of the Boötes civilization galaxy, Xiao Yu embarked on the road to the station of the Lyra civilization. This is another long voyage, a long journey of more than 4,600 light years. Even at Xiao Yu's speed,
It will take almost a hundred years to arrive.
But this time the journey was not peaceful. Halfway through the voyage, Xiao Yu encountered an unexpected event, that is, a supernova exploded.
This supernova exploded more than 3,000 light-years away from Xiao Yu and exploded into pieces, leaving no white dwarf, no neutron star, and no black hole. All its matter exploded violently.
It was completely thrown into space and turned into a spreading planetary nebula.
This is a very rare cosmic spectacle, an unstable pair of supernova explosions.
A distance of more than 3,000 light-years, if it were an ordinary supernova explosion, Xiao Yu could actually ignore it. After all, this distance is too far. And Xiao Yu's current technology has developed to a certain extent at this distance.
Resisting the attack of explosive energy is nothing to Xiao Yu.
However, the unstable supernova explosion is not an ordinary supernova explosion. The energy it releases is so intense that the energy it erupts can still destroy it after traveling a distance of more than 3,000 light years.
Xiao Yu's fleet had an impact. There was no way. In order to avoid unexpected losses, Xiao Yu had to temporarily separate the fleet from the curvature space. He placed the planet battle star in front and parked all the battleships at the Earth.
Behind the huge body, with the help of the powerful defense of the Earth, it withstood this disaster.
"Unstable pair supernova... This is the first time I have encountered it since entering the void of the universe. Such things are really rare. Well, the data observed this time are enough for me to study for a long time."
Looking at the bright 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 supernova has such a powerful ability. When the unstable supernova explodes, any powerful existence will be eclipsed, not even a river system can compare with it.
Unstable pair supernova is a very extreme supernova explosion phenomenon. It can only occur in huge stars with a mass of 130 to 250 times the mass of the sun. Xiao Yu has a deep understanding of this type of supernova,
According to Xiao Yu's theory, the main reason why such a supernova explosion occurs is because the gamma ray energy at the core of the star is too powerful, and the too powerful gamma ray will collide with the atomic nucleus to produce free electrons and positrons.
In this case, the pressure at the core of the huge star will decrease, causing the star to locally collapse. Then a large number of rapid, out-of-control nuclear burning will completely blow away the entire star.
Note that an unstable supernova will not leave any dense core such as a white dwarf, a neutron star or a black hole. Because the energy of the explosion is too violent, the entire star will be completely blown away in such an explosion.
There is no chance to form these dense stars at all. This is the biggest difference between it and ordinary supernova explosions. Although type IA supernovae will not leave any traces, they occur on white dwarfs, and their power and scale
, cannot be compared with the unstable pair of supernovae.
So you can imagine how powerful the explosion of unstable supernovae will be. Because unstable supernovae are so rare, even Xiao Yu has not seen it a few times. When he was on earth, Xiao Yu saw two
It was suspected that it was an unstable supernova explosion remnant. Speaking of actually witnessing the entire explosion process, this was Xiao Yu's first time.
"It's pitiful. It is estimated that with this unstable supernova as the center, all low-level creatures within a radius of several thousand light years will be killed." Xiao Yu secretly sighed, "If we encountered such a violent event in the earth's age,
If it explodes, all humans 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 era. But it is a pity that the earth will be destroyed in the end."
From this point, we can also see the dangers of the universe. Because you never know what kind of crisis you will encounter at the next moment. You must know that the energy of a supernova explosion propagates at the speed of light, so before you notice this
When a star explodes as a supernova, the destructive energy it releases has already arrived at the same time. You will be killed instantly without even having time to react. To prevent this kind of thing in advance, the only way is to use Level 5
Civilized tachyon detection technology has taken the initiative to detect these stars. But there are so many stars in the universe, how can a civilization monitor the situation of each star in real time? Even if pre-screening methods can be used,
Only a few stars with the potential to explode are monitored, but how many level five civilizations are there 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 his journey. Although Unstable vs. Supernova was exciting, it was not enough to stop Xiao Yu.
Xiao Yu can do it without paying much attention to an unstable supernova explosion, but some beings cannot do it. For example, the former leader of the Pegasus civilization has always remembered those who were before the alien beasts of the tree race destroyed their capital planet.
Those Pegasus civilized people who escaped.
They were right in front of Xiao Yu, closer to the exploded unstable supernova, so they were more strongly affected. And their technology was not as advanced as Xiao Yu. The most serious thing was that their escape
Many of the fleets are not battleships, but ordinary civilian, commercial, and industrial spaceships. The defense capabilities of these spacecrafts are much worse than those of battleships.
Therefore, this sudden and unreasonable disaster caused them huge losses. Nearly half of the spacecraft and people died in this disaster, and the remaining half of the spacecraft generally suffered serious damage, with engines burned out and energy reserves
There are countless incidents such as exhaustion and damage to precision parts.
During the period of escape, this part of the people of the Pegasus civilization has produced new leaders and various related institutions. The new government quickly assessed the current damage situation and carried out a series of
post-disaster relief matters.
But the current situation really makes him unable to be optimistic.
"I have always firmly believed that any suffering is a test for 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 wavered.
.I am thinking, why do these series of disasters happen to our civilization? Can we, can we really overcome the difficulties before us?"
The new leader who had just finished an impassioned speech and successfully aroused the fighting spirit of the surviving people, after finishing the speech and returning to his private residence, his whole person became decadent. He looked in front of him.
He couldn't help but burst into tears when he received the fleet damage report.
The reality before him was cruel. Because the damage was too severe, the fleet had lost the ability to continue its voyage. So the only way at present was to find a nearby planet to station on. However, the Pegasus civilization had not transformed at this moment.
The power of the planet, the number of people, the number of various mechanical equipment is too small, and there are gaps in science and technology. The scarcity of scientists determines that for at least thousands of years, their technological level will only go backwards rather than forward.
Finding a suitable planet for them to live on, or a planet that only needs a very simple transformation to be suitable for survival, and then focusing on cultivating future generations, developing education, and increasing the number of scientists as much as possible is their only chance of survival.
If they are stationed nearby, it means that in order to maintain the survival of the people, their main energy must be on transforming the planet, and education will be delayed.
This delay may delay the hope of the entire civilization.
This series of blows has pushed the new leader's ambition to the brink of collapse.
After crying silently in the empty room for half an hour, he stood up, wiped away the tears on his face, straightened his appearance, and walked out of the room. He returned to that kind of wisdom again.
With it in hand, it looks like it cannot be defeated by any difficulty.
Before he could give instructions to the assistant who came up to him, he felt a violent shaking, as if an earthquake had occurred on the spacecraft. But he knew that an earthquake could not occur on the spacecraft.
"What exactly happened? Go investigate and report to me immediately..."
He ordered in a steady voice. Although he was very frightened at the moment, he knew that this emotion could not be shown or seen by anyone.
