Through long-term experiments, Xiao Yu found that any intelligent life form copied by cloning and other means will have some kind of intellectual defect. This defect originates from the genetic level, and with Xiao Yu's current technology, it cannot be repaired for the time being. This also means that the plan to obtain a large amount of scientific research through cloning is basically impossible to achieve. It is precisely because of this that Xiao Yu did not massively expand the number of Lucca people through this kind of jishu, but only let them reproduce naturally.

It is precisely because of this that Xiao Yu is so eager for intelligent life, especially intelligent life with scientific research ability.

The process of creating life seems to belong to the great universe, the great nature, and cannot be intervened by artificial liliang.

With the strength of the Taihao civilization, it took more than two million years for the human beings with the genes modified by the Taihao civilization to develop to the current stage of civilization, which is estimated to be related to this reason.

Under such circumstances, the more than 4,000 scientists of various races captured this time are the most valuable treasures.

In this county-level spaceship, hearing Xiao Yu's words, dozens of mantis scientists cried with joy and cried excitedly.

"After hundreds of years of wandering and captivity, I finally met a kind civilization."

"Pity my child, who was slain by the abominable civilization of Merian before he reached adulthood...... It would be nice if it could have Yujian you earlier, if it hadn't died, it would have grown into an outstanding scientist. ”

"Master, please rest assured, we will definitely contribute all our knowledge and scientific research capabilities to promote your scientific and technological development......"

"That's fine." Xiao Yu nodded slightly, "It's just that at this stage, I have to wronged you to live here for a while." The renovation of your new home is underway. It is expected that in a month, you will be able to move in. ”

Xiao Yu has already dispatched several city-level spaceships and is undergoing intense transformation in related aspects. After the renovation is completed, it will be ready for these scientists to live in.

"Xiexie, it's really too Xiexie." Dozens of mantis scientists threw themselves on the ground and expressed their respect for Xiao Yu.

Such a scene is happening at the same time in more than 100 county-level spaceships. By recovering these alien scientists, Xiao Yu once again realized the importance of strength to a civilization.

Of course, Xiao Yu is not a philanthropist. Being so kind to these civilizations is because they value them. In order to form a deterrent, Xiao Yu also found several of the toughest and least likely to surrender from the captives of the Molian civilization. There was a live broadcast of all civilized creatures. During the live broadcast, Xiao Yu used the most cruel means to kill these Molian people. It was a great deterrent to these alien scientists.

"Make them understand. If you do it well, you want what you want, and if you don't want to do it well, hum, I'm not a soft-hearted person. ”

After subduing these alien scientists, the only thing that gave Xiao Yu a headache. Only these unusually tough creatures of the Morian civilization remained. If they are killed, it is a pity, but if they are not killed, they will not surrender to themselves.

"Sooner or later, our mother civilization will catch up with you. If you are kind to us, maybe we can say a few kind words to the Führer and only reduce your civilized creatures to slavery, but not kill you! ”

"The strength of our Molian civilization is not something that you can understand as a small fourth-level civilization! Don't think you're going to be able to hold off our fleet with these tattered junk guards that you picked up out of nowhere! Surrender before it's too late! Only after surrender can you live! ”

"There is no way that our civilization will give in to the enemy! You should die of this heart before it is too late! ”

Every time Xiao Yu tried to brainwash these creatures and subdue them, words like this would erupt. For this reason, Xiao Yu carried out a brutal suppression, and in the past few days, he slaughtered hundreds of Molian humans, but it did not have any effect.

"Did I capture you or did you capture me?" Xiao Yu thought unusually angrily in his heart, "If it weren't for the fact that you have some fifth-level civilization technology, I would have killed you a long time ago and used them to raise flowers." Provoked me, really when I didn't dare to do this? ”

"Let's put this matter aside for a while." Xiao Yu gave up the idea of subduing them for the time being.

After a few days of subduing work, a large number of Molian Civilization computers imitated according to Xiao Yu's usage habits had been manufactured, and Xiao Yu began intense analysis and research work, and at the same time, a comprehensive research work on the captured Molian Civilization Provincial Spaceship had also begun.

As the work progressed, a large amount of information about the fifth-level civilization entered Xiao Yu's mind.

"Whew...... I see. Xiao Yu breathed a sigh of relief.

Among these fifth-level civilization materials, excluding those useless materials, among the most important scientific and technological documents, the term that is mentioned the most often is "fast son".

"It turns out that antimatter does not only represent antimatter, through a comprehensive study of antimatter, you can grasp the relevant properties of dark matter and negative matter, which is the true scientific and technological essence of the fifth-level civilization."

The so-called tachyon, a similar concept has been proposed in the age of the earth, which corresponds to the "tachyon".

In the microscopic shijie, protons, neutrons and other particles constrained by strong interaction forces are called hadrons, which belong to baryon and electrons belong to lepton according to their weight. However, whether it is a proton or a neutron, a hadron or a baryon, they are all chottons.

Of the 61 elementary particles predicted by the Standard Model, all but photons are chettrons. Because their speed of motion can only reach below the speed of light, they can get infinitely close to the speed of light and cannot reach it.

Giving them energy accelerates these particles, and the more energy you give them, the faster they will be. But they have a speed cap, and that's the speed of light. Their speed of motion cannot exceed the speed of light, so they are called slow tons.

With the exception of photons, these particles all have masses above zero, that is, their masses are positive. In fact, both positive matter and antimatter have positive mass. The criterion for distinguishing positive and antimatter is only the difference in charge.

Tachyons are a completely new type of particle. The biggest difference from a positive mass particle is that its mass is negative. So its speed is eternally fixed above the speed of light. If you give energy to the tachyon, the speed of the tachyon increases, and the speed of the tachyon is the opposite, and if you give energy to the tachyon, the speed of the tachyon slows down. The more energy is given, the slower the speed of the tachyon.

Like the tachyon, the tachyon also has a speed limit. The lower limit of the speed of the tachyon is the speed of light, that is, the speed of the tachyon is always faster than the speed of light. It can only be infinitely close to the speed of light, not below it.

Because of this property, tachyons cannot be directly observed by any observation instrument. Because all intelligent beings live in the shijie of the slow son. But just like a black hole, it cannot be directly observed, but its existence can be indirectly inferred from a certain effect it brings.

The discovery and utilization of tachyon is the greatest feature of the fifth-level civilization.

"I see...... However, there seems to be no mistake in using the large-scale production capacity of antimatter as a criterion. The discovery and exploitation of tachyons are closely related to antimatter and even dark matter. I see, I see. ”

At this moment, Xiao Yu had a feeling of sudden realization.

In the age of the earth, human beings have discovered the first three types of matter, which are positive matter, antimatter, and dark matter.

Positive matter is the matter we usually come into contact with, antimatter is an extension of antiparticles, as we all know, inside the atom, electrons carry a negative charge, spin quantum number is positive half, antielectron is just the opposite, it carries a positive charge, spin quantum number is negative half. Not only electrons, but also neutrons, protons, etc., have their own antiparticles.

Matter made up of particles is positive matter, and matter made up of antiparticles is naturally antimatter. This is where antimatter comes in.

Dark matter is more mysterious, according to mass measurements, most of the mass in the universe is contributed by dark matter, but it seems that this dark matter does not contribute anything other than gravity, and cannot be observed or studied. Humans in the age of Earth only speculated about the existence of dark matter, but did not carry out any relevant research on it.

Level 5 civilization is different. The fifth-level civilization took the study of antimatter as a breakthrough, and had a systematic theoretical technology for antimatter and dark matter, and discovered a new substance, tachyon.

Tachyons are also divided into many different types, the mass of tachyons is negative, and the matter made up of tachyns is a negative substance.

Tachyons have many wonderful physical properties. Because its speed is always above the speed of light, it cannot be directly observed. Because it has a negative mass, it can annihilate itself with all positive matter in the broad sense of the word, and return to nothingness. A kilogram of negative matter can react with a kilogram of positive matter, or antimatter, and the reaction process is that both disappear together and disappear from the universe. And, in the process, no energy is emitted, no radiation is emitted.

The law of conservation of mass and energy fails within a small area of tachyons, but remains conserved on the entire cosmic scale.

At this moment, a question that had been bothering Xiao Yu for a long time was finally answered.

"It turns out that the inexplicable mass increase that I have observed many times in the Large Particle Collider is due to tachyons......" (to be continued......
