Chapter 269: Stellar weapon

Supernova explosions can only occur on stars that are more than eight times the mass of the sun. The lifetime of a star is inversely proportional to its mass, that is, the larger the mass, the shorter its lifetime. Stars with a mass more than eight times that of the sun generally have a lifetime of only tens of millions of years. Some supermassive stars, such as stars with a mass several dozens of that of the sun, may have a lifetime of only a few million years.
Because the greater their mass, the more they need the core to increase their energy against their own gravity. In this case, their nuclear fusion reaction is much more intense than that of ordinary stars, and hundreds of millions of tons of material are converted into energy every second. With such a drastic and rapid material conversion, no matter how large their mass is, they cannot support it for too long.
The lifespan of millions of years is only a blink of an eye on the cosmic scale. At the end of their lives, they will die violently in the form of a supernova explosion, presenting a brilliant cosmic firework for the entire universe.
This is the most magnificent event in the universe. The death of a star will bring the conditions for the birth of life. Although this star exists for a short time, it is an indispensable part of the evolution of the universe. It can be said that without supernovas and without these massive stars, there would be no life in the universe, at least, no humans.
Because in the periodic table, all the elements heavier than iron were all produced in such violent events as supernova explosions or neutron star collisions.
In the age of earth, all the heavy elements such as gold rings, silver bracelets, copper wires used in cables, etc., came from the remains of supernovae. Because the star fuses to iron, it can only fuse out iron and below elements. Just as the supernova exploded, all the elements on the periodic table were created and spilled into the universe.
Supernova explosions give these materials powerful kinetic energy, which will diffuse into the universe and form magnificent nebulae. At some point, if the conditions are met, they will re-aggregate together. If their mass is large enough, they will form a second or third generation star. If the mass is not large enough, they will form rocky planets Gaseous planets, if there is a rocky planet right next to a young and healthy star, after getting the right temperature, supported by the rich elements that make up the planet, it may slowly rise above it Develops life ...
This is how humans were born. To form all the elements of the benevolent body, all the elements we often come into contact with, except for the most basic element, hydrogen, the rest are all derived from stars. Elements of iron and below originate from stellar fusion, and elements above iron are derived from corpses after the stellar supernova explosion.
Not only humans, but all intelligent beings in the universe are all children of stars, children of stars in the true sense. Because it's the stars that give us everything.
This is the whole process of supernova explosion. At present, it can be known that the star to which the aging ghost group depends is only about the same mass as the sun, and it is not qualified for a supernova explosion. Moreover, even if it has this qualification, when will a supernova explosion occur, is it Xiao Yu's control?
However, Xiao Yu already had the prototype of stellar weapons. That is, like the guardian civilization, the weapon that destroys a star by causing a star to explode.
But one thing, Xiao Yu's understanding of stellar weapons is still very shallow, it can be said that there is no clue, stellar weapons only exist in Xiao Yu's conjecture. What Xiao Yu needs to do now is to make a guess as to whether the Merian civilization has stellar weapons.
After a while of contemplation, Luca III said, "At present, the star weapons in our theoretical system can only destroy stars through the mechanism that triggers a supernova explosion. A supernova explosion is caused by the sudden loss of energy support inside the star, leading to The outer material falls inward and is caused by an impact. Stellar weapons are also based on the same principle. There is a special tachyton that does not react with low-density objects, but is hindered by high-density objects. The object annihilated. This type of tachyton is very much in line with the idea of ​​stellar weapons. "
"Yes." Xiao Yu nodded and said, "Like a sun-mass star, its core density will be about 150 times that of water. This density is enough to allow this type of faston to react with it. After the tachyton is launched, it will penetrate the thin outer layer of the star, and travel to the interior of the star. After encountering the high-density material in the core of the star, it will annihilate with them. We can pass this Means, hollowing out the core area of ​​a star, letting it lose its core energy support, causing it to fall inward under the influence of external pressure and its own gravity, thus creating a process similar to the supernova explosion. In fact, I estimate The four stars in Tianyuan, which were destroyed by the guardian civilization, have exploded because of this mechanism. "
"This is indeed a feasible stellar weapon manufacturing solution." Luca IV said, "But the problem we are facing is not one. In the process of building this stellar weapon, there are many obstacles waiting. We have obstacles not only at the technical level, but also at the scientific level ... At our current rate of technological development, we cannot manufacture such weapons without more than 800 years. "
"Yes." Luca III took the words of Luca 4, and said, "One of the biggest obstacles is that in the face of a giant such as a star, how big is the hollow core of the star? Can it cause it to explode? I estimate that at least a few trillion tons of negative material cannons can achieve the purpose. But ... just ordinary ordinary material cannons, the power we can currently reach, but only 8,000 tons It ’s just 8,000 tons and trillions of tons. This gap is really too big. Moreover, the negative material tachyons required by stellar weapons are not the same as ordinary negative material tachyons. The manufacturing process is much more difficult. "
"I know this very well," Xiao Yu said. "In a short period of time, we can't make practical stellar weapons. That's why I ask you to make an assessment to evaluate the technology of the Merian civilization. Well, in fact, I know very well that it is absolutely impossible for the Merian civilization to have such a weapon. I just let you evaluate whether the Merian civilization has a specific method of making such weapons in the theory. . "
"If they do, that's great. They have theory. We have a huge force of action. For fifty years, we may not be able to make such weapons."
"That's my whole idea. Now, let's evaluate it."
Xiao Yu said.
Lucca III, Lucca IV, and the other three scientists are all silent.
"Before I make an assessment, I first need to make sure that even if the Merian civilization really has a method of making this weapon, how can we let them give us this technology? We are currently in a hostile relationship." The scientists first raised objections.
"This problem will be solved by me and the scientists in the psychosocial department led by Luca II and Luca II. As science and technology scientists, you don't need to consider this problem." Xiao Yu said very simply.
"Well ... First of all, as a civilization with a deeper understanding of negative matter than we do, there must be similar ideas in the Merian civilization. The obstacles they create are the same as those of us, both in the development of specific technical details and material technology. In terms of progress. We have a provincial ship of the Merian civilization. By analyzing this provincial ship, perhaps we can find some clues and make a clear assessment of the specific scientific and technological strength of the Merian civilization. "
"I have prepared all the materials, please take a look." Xiao Yu signaled, showing the data of the provincial spaceship captured from the Merian civilization.
The conference room fell into silence ~ EbookFREE.me ~ These scientists took out their personal computers and began to carry out intensive calculations and calculations.
"In terms of military science and technology, the Merian civilization is at least five hundred years ahead of us ... above this level, their material technology will probably develop to ..."
"Energy technology will probably develop to ..."
In the intense calculations, one by one the data evaluation conclusions came out.
Each of these data is more advanced than Xiao Yu's now, but the extent of this excess is not too outrageous. From this aspect, we can also see that after reaching a relatively advanced stage of civilization, the development of science and technology is difficult.
In terms of military industry, the Morian civilization is at least five hundred years ahead of Xiao Yu, but the development time of five hundred years has made only such a little progress.
After about half an hour, Luca III stood up.
"In terms of comprehensive calculations, the possible surname of the preliminary manufacturing theory of stellar weapons in the Morian civilization is about 60%."
This result refreshed Xiao Yu's spirit. In fact, Xiao Yu's own evaluation conclusions are similar to this figure.
"Is it sixty percent? This number is high enough to allow us to take this risk. Then ... while carrying out the concealment plan, start the Stellar Weapon Plan. Send a newsletter to the Merian civilization Yi, get in touch with them, then, whether it is to use deceptive methods, lure methods, in short, let them cooperate with us, in the remaining 50 years, will have a combat capability of negative material artillery Build it!
