Zhu Zhen calmed down his emotions and said: "Based on the observations of Kaiwu's ultra-large sensitive equipment and the latest starfish map of the universe, we concluded that the energy of the 'unstable pair supernova' explosion was so great that the black hole was affected by It was affected by the impact, changed its orbit, and came to our salvage ship. However, due to the disturbance of the 'unstable supernova', our various sensors failed to provide early warning."
Wang Jiacheng was a little confused and asked: "Where did the supernova come from? There are no stars at all within a distance of several thousand light-years around Kaiwu. Naturally, a supernova will not evolve!"
On the contrary, Junker Adam looked suddenly enlightened. His understanding of the universe sea was much more comprehensive than that of Wang Jiacheng.
So Zhu Zhen asked the spacecraft's optical brain to bring up the starfish map of the universe before the update, and ordered it to display all the stars within 10,000 light-years around Kaiwu.
What is surprising is that there are three stars, which are about 5,500 light-years away from the Kaiwu probe's current position. One of the stars is pale in color, much brighter than the other two, and flickers back and forth unsteadily.
Juncker Adam interjected: "Chairman, the cosmic sea is indeed empty, but there are still some sparse star systems. Due to the small brightness of individual stars, they cannot be distinguished by the naked eye when they are far away, even when they are displayed on the cosmic star map. Less than. They can only be discovered unless they are magnified millions or even hundreds of millions of times. For example, there is no galaxy. Under normal circumstances, it is only the size of a grain of rice on the star map. If it is not magnified, it will be thought to be a star. And. The sun in the Lulunu star system below the Utopia galaxy is completely invisible. There are 130 billion stars in the Utopia galaxy."
"Yeah!" Wang Jiacheng finally understood. The universe is really too big and the starry sky is vast, and it is impossible for a single intelligent creature to know everything. The number of star systems per unit space in the universe is so small that it can almost be ignored, so no one usually pays attention to the existence of these things.
Zhu Zhen continued: "If these three stars evolve into supernovae and an unstable supernova explosion occurs, the energy will spread in all directions at the speed of light. According to time calculation, it will just arrive at our Kaiwu No. 1 now."
Then the spacecraft's optical brain began to deduce based on the design model of Zhu Zhen's team.
After 350 years, the pale and twinkling star evolved into a supernova, and its brightness suddenly increased, even brighter than the entire Milky Way on Earth. Wang Jiacheng's heart trembled.
This supernova exploded 5,500 light-years away from Kaiwu, and the whole thing was blown 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 spreading stripe nebula.
This is a rare cosmic spectacle and an unstable supernova explosion.
At a distance of 5,500 light-years, if it is a normal supernova explosion, it will not have any impact on the Kaiwu. After all, this distance is far enough, and the Kaiwu is a latest salvage ship, and the protective shield has also passed Deliberately strengthened. At this distance, resisting the attack of explosive energy is a piece of cake for Kaiwuhao.
However, the unstable supernova explosion is not an ordinary supernova explosion. The energy it releases is so intense that the energy it explodes can still cause damage to Kaiwu after a long journey of 5,500 light years. Influence.
"Unstable pair of supernovae... This is also the first time I have encountered it after studying cosmology. Such a thing is really rare. I will study this simulation data carefully in the future!" Zhu, who has explosive academic attributes Zhen said to himself.
Yes, instability has such a powerful ability against supernovae. When it explodes, any powerful existence will be eclipsed, even if it is thousands of light years away, it will be affected.
Unstable pair supernova is a very extreme supernova explosion phenomenon that can only occur on huge stars with a mass of 130 to 250 times the sun. Although Zhu Zhen has not seen its explosion with his own eyes, his profound knowledge gives him a deep understanding of this type of supernova.
According to Zhu Zhen's theory, the main reason why such a supernova explosion occurs is because the gamma ray energy in the core of the star is too powerful. Gamma rays that are too powerful will collide with atomic nuclei to produce free electrons and positrons. In this case, the pressure at the core of the giant star will decrease, causing the star to locally collapse, and then a large amount of rapidly out-of-control nuclear fuel will completely blow the entire star away.
It is important to note that after an unstable pair goes supernova, nothing such as a white dwarf is left behind. A dense core such as 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, leaving no chance to form a dense star.
This shows how powerful the explosion of instability on supernovae will be. Because instability is so rare for supernovae, Zhu Zhen, an outstanding cosmologist, has never actually encountered it and only theoretically understood its operating mechanism. He never expected to encounter it during his exploration of the Cosmic Sea.
Wang Jiacheng stared at the terrible destructive power in the holographic image simulated by the optical brain. He was frightened for a while and murmured: "It's really lucky. If this happened in all countries in the universe, it is estimated that with this unstable pair of supernova as the center, the radius of the circle is 2000 light years. All creatures will be killed!"
Zhu Zhen smiled bitterly and said: "Chairman, this is not possible. Countries in the universe have already established complete monitoring networks for stars in various galaxies. We don't know if a supernova has exploded! The universe is an exception. That’s all.”
From this point, we can also see the danger of the cosmic sea, 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. By the time you notice that the star has undergone a supernova explosion, the destructive energy it releases has already arrived at the same time. Without complete protection in advance, you will be killed instantly without even having time to react.
Thinking of this, Wang Jiacheng said gratefully: "Senior Ya, thanks to your reminder this time, our Kaiwu raised the protective cover in advance. Otherwise, I don't know what high-speed particles penetrated the bulkhead just now, and everyone would have been alive." Know!"
Junker Adam struggled to squeeze out a smile and said: "It's just good luck. I didn't know that I would encounter such a fatal and rare astronomical phenomenon!"
He was telling the truth. He had made such a suggestion just now because he was afraid of death, and he did not have any real foresight.
Thousands of years ago, Junker Adam came to the space sea to explore and hunt for treasures, and installed a honeycomb scattering escape capsule in the spacecraft. He either knew it was useful, or simply heard that the metal can partially resist the annihilation wave, so an escape made of its material Of course the cabin might be useful.
Being cautious when doing things is Junker Adam's motto, and it is also the magic weapon for him to survive the adventure of the cosmic sea.
Now, although he may have escaped a disaster just now, the key is how to face the next dilemma, so his face is a bit ugly.
At this time, a dark and empty space in the simulated holographic image was distorted, as if something existed somewhere, but there was no light spilling out from anywhere, so it seemed like there was nothing.
Then countless orange haloes suddenly appeared around it. The haloes formed an irregular fan shape, and the central area was still dark and nothing, which was very strange.
The halo disappeared soon after, and then reappeared several times, each time getting bigger and darker each time. A dark and empty area can be clearly distinguished. There is a clear change in position, and it is moving faster.
"That's a black hole!" Robot Servant No. 2 beside Junker Adam explained to him.
Zhu Zhen pointed to the holographic image and said: "Yes, this black hole was changed in orbit by the huge energy of the unstable supernova explosion, accelerated its movement, and came towards our route."
By now, Wang Jiacheng, Juncker Adam and other supervisors in the bridge room have generally understood what Zhu Zhen originally said. The instability caused by the energy of the supernova explosion affected the sensors on the Kaiwu salvage ship to detect its approach in advance.
Zhu Zhen continued his report, saying: "The mass of this black hole is about thirty-seven times that of a standard star, and it came to the Kaiwu without any warning. The unmanned spacecraft and resource detectors that are currently lost are all It’s to be swallowed up by it.”
Hearing this, Wang Jiacheng felt calm. These losses are not big and can be afforded. Even if the black hole is close, you can still use the anti-gravity engine on the Kaiwu to fight it.
However, what Zhu Zhen said made Wang Jiacheng feel heavy.
"If it's just like this, it doesn't matter. The most important thing, the most important thing..." Zhu Zhen said uncertainly: "The black hole is still accelerating, and the energy of the unstable supernova explosion has not completely disappeared. Our super Large and sensitive equipment cannot accurately measure the black hole's event horizon and its distance from the Kaiwu! The superlight engine and plasma engine on the spacecraft are under maintenance and will take 15 to 20 days to start working!"
Wang Jiacheng realized the seriousness of the problem. Although the anti-gravity engine can resist gravity, it does not make gravity disappear.
The law of conservation of energy still holds true on this alien world. Once spacecraft and warships fall into the inescapable horizon of a black hole, they can rely on the anti-gravity engine to prevent their fall, and then use the plasma engine to propel them back to normal space.
But there is a prerequisite for this, that is, the anti-gravity engine cannot fail. Otherwise, the plasma engine will not be able to accelerate the spacecraft to the speed of light, and there is no way to escape the shackles of the black hole; the super-light engine cannot be turned on in a high gravity environment and is unstable. The space cracks will directly tear the spacecraft into pieces.
According to experiments, the longest time an antigravity engine can operate continuously within the black hole event horizon is 22 hours.
