Chapter 269 Stellar Weapon

Supernova explosions can only occur in stars with a mass more than eight times that of the sun. The lifetime of a star is inversely proportional to its mass, that is, the greater the mass, the shorter its lifetime. Stars with a mass more than eight times that of the sun generally have a lifespan of only tens of millions of years. Certain supermassive stars, such as those tens of times the mass of the sun, may live only a few million years.

Because the more massive they are, the more they need the core to raise more energy against their own gravity. Under such circumstances, their nuclear fusion reactions are much more violent than those of ordinary stars, and more than hundreds of millions of tons of matter are converted into energy every second. Under such a violent and rapid material conversion, no matter how large their mass is, they cannot last for too long.

A lifespan of millions of years is but a blink of an eye on a cosmic scale. At the end of their lives, they will die heroically in a supernova explosion, presenting a splendid cosmic fireworks for the entire universe.

This is the most magnificent event in the universe. The death of a star will bring conditions for the birth of life. Although this kind of star exists for a short time, it is an indispensable part of the evolution of the universe. It can be said that without supernovae, without these massive stars, there would be no life in the universe, at least, no human beings.

Because in the periodic table of elements, all elements heavier than iron are all produced in heroic events such as supernova explosions or neutron star collisions.

In the earth age, all heavy elements such as gold rings and silver bracelets on human fingers, copper wires used in cables, etc., all came from the remains of supernovae. Because the star fuses as far as iron, it can only fuse elements of iron and below. At the moment of the supernova explosion, all the elements on the periodic table were produced and thrown into the universe.

The supernova explosion endows these substances with powerful kinetic energy, and they will spread into the universe to form magnificent nebulae. At some point, if the conditions are met, they will come back together, and if their mass is large enough, they will form a second- or third-generation star, and if they are not large enough, they will form rocky planets or planets. Gas planets, if there is a rocky planet right next to a young and healthy star, after they get the right temperature, supported by the abundance of elements that make up the planet, they may slowly grow on top of it. The development of life comes...

This is how humans were born. All the elements that make up the human body, all the elements that we come into contact with on a daily basis, except hydrogen, the most basic element, the rest of the elements all come from stars. Elements below iron come from stellar fusion, and elements above iron come from the corpses of stars after supernova explosions.

Not only human beings, but all intelligent life forms in the universe are all sons of stars, sons of stars in the true sense. Because it is the stars that give us everything.

This is the whole process of a supernova explosion. At present, it can be known that the star that the aging ghosts are attached to has a mass only about the size of the sun, and it is not qualified for a supernova explosion. Moreover, even if it has this qualification, how can Xiao Yu control when the supernova explosion occurs?

But Xiao Yu already had the prototype of a star weapon in his heart. That is to say, like the guardian civilization, a weapon that destroys a star by triggering a star explosion.

But there is one thing, Xiao Yu's understanding of stellar weapons is still very shallow, and it can even be said that he has no clue. Stellar weapons only exist in Xiao Yu's conjecture. All Xiao Yu needs to do now is to make a guess as to whether the Molian civilization has stellar weapons.

After a while of contemplation, Luca III said: "Currently, the stellar weapons within our theoretical system can only destroy stars through the mechanism of triggering supernova explosions.

The supernova explosion is caused by the sudden loss of energy support inside the star, causing the outer layer of matter to fall inward and cause an impact. Stellar weapons are also based on the same principle. There is a special tachyon that does not react with low-density objects. But it will be hindered by high-density objects, thus annihilating high-density objects. This kind of tachyon is very in line with the idea of ​​a star weapon. "

"Yes." Xiao Yu nodded and said, "A star with the mass of the sun will have a core density about 150 times that of water, which is enough for this tachyon to react with it. After this kind of tachyon is emitted, it will penetrate the thin outer layer of the star and go all the way to the interior of the star. After encountering the high-density matter in the core of the star, it will annihilate both of them. We can use this The method is to hollow out the core area of ​​a star, make it lose the energy support of the core, and cause it to fall inward under the action of external pressure and its own gravity, thereby creating a process similar to a supernova explosion. In fact, I estimate It is because of this mechanism that the four stars of Tianyuan, which were destroyed by the Guardian civilization, exploded as a supernova."

"This is indeed a feasible solution for the manufacture of stellar weapons." Luca IV said, "But the problem we face is not one. In the process of building this kind of stellar weapon, there are many obstacles waiting We have not only technical obstacles, but also scientific obstacles... Judging from our current technological development speed, it is impossible for us to create such weapons without more than 800 years."

"Yes." Luca III took over the words of Luca IV, and said: "One of the biggest obstacles is, facing a giant like a star, how big a hole does it need to dig out in the core of the star before it can be destroyed?" Can it cause it to explode? I estimate that at least several trillion tons of negative matter cannons are needed to achieve the purpose. But... just ordinary negative matter cannons, the power we can achieve at present is only 8,000 tons The difference between the 8,000-ton class and the trillion-ton class is too huge. What's more, the negative matter tachyons required by stellar weapons are different from ordinary negative matter tachyons. The manufacturing process is much more difficult."

"I know this very well." Xiao Yu said, "It is impossible for us to create a star weapon with practical significance in a short period of time. That's why I ask you to make an assessment, and evaluate that the Merian civilization has this kind of technology Well, in fact, I know very well that it is absolutely impossible for the Merian civilization to possess such weapons. I just want you to evaluate whether the Merian civilization has a specific method of manufacturing such weapons in theory. .”

"It would be great if they have them. They have theories, and we have a huge force of action. In fifty years, we may not be able to manufacture such weapons."

"That's my whole idea, now, you guys evaluate it."

Xiao Yu said.

Luca III, Luca IV, and the other three scientists fell into silence.

"Before making an assessment, I first need to make sure that even if the Merian civilization really has the manufacturing method of this weapon, how can we get them to hand over this technology to us? We are currently in a hostile relationship." One A scientist was the first to raise an objection.

"This problem will be solved by me, Luca II, and the scientists of the Department of Psychology and Society led by Luca II. As scientists of the Department of Science and Technology, you don't need to consider this issue." Xiao Yu said very simply.

"Well... First of all, as a civilization with a deeper understanding of negative matter than ours, there must be similar ideas in the Merian civilization. Their manufacturing obstacles are the same as ours, and they all lie in the development of specific technological details and material technology. In terms of the degree of progress. We have a Merlian civilization provincial spacecraft, and by analyzing this provincial spacecraft, perhaps we can find some clues and make a clear assessment of the specific technological strength of the Merlian civilization.”

"I have prepared all the materials, please take a look." Xiao Yu gestured, and displayed the information of the provincial spaceship captured from the Merian civilization.

The conference room fell into silence. These scientists each took out their personal computers and began to carry out intense calculations and calculations.

"In terms of military technology, the Merian civilization is at least five hundred years more advanced than us... At this level, their material technology will probably develop to..."

"Energy technology will probably develop to..."

In the tense calculations, the data evaluation conclusions were drawn one by one.

Each of these data is more advanced than Xiao Yu's now, but the extent of the excess is not too outrageous. From this aspect, it can also be seen that after reaching a relatively advanced stage of civilization, the development of science and technology is difficult.

In terms of military industry, Merian civilization is at least five hundred years more advanced than Xiao Yu, but in the five hundred years of development, only such a little progress has been made.

After about half an hour, Luca III stood up.

"Based on a comprehensive calculation, the possibility of the preliminary manufacturing theory of stellar weapons in the Merian civilization is about 60%."

This result lifted Xiao Yu's spirit. In fact, Xiao Yu's own evaluation conclusion is similar to this number.

"Sixty percent? This figure is already high enough, enough for us to take risks. Then... while implementing the concealment plan, let's start the star weapon plan. Send a communication to the Merian civilization Instruments, get in touch with them, and then, whether it is by deception or lure, in short, we must let them cooperate with us, and in the remaining fifty years, we will use negative matter cannons with actual combat capabilities Build it!"
