Super Battleship Reborn

At the fourth-level civilization stage, Xiao Yu had already discovered the traces of tachyons during experiments, but he didn't know it at the time. .

According to the normal technological development process, it should be that with the development of science and technology, Xiao Yu gradually summed up the law of this phenomenon, and put forward his own hypothesis, and then verified them one by one. After a long time and countless studies, he could get This is the conclusion of Tachyon.

In this process, it is also accompanied by the development of other technologies, such as energy technology, antimatter, and dark matter related research. This is the advancement of the entire technological level.

But now, Xiao Yu's other related technologies have not advanced enough, and he has already known in advance that this is because of tachyons, so there is such an inexplicable increase in quality. This is a good thing, which means that Xiao Yu can avoid many detours and greatly speed up his technological progress.

Through this, Xiao Yu once again realized a truth. That is, the technological development of civilization is gradual. If Xiao Yu is still in the third-level civilization stage, then the information obtained so far is of little use to Xiao Yu. For a civilization that doesn't even know about curvature navigation and the unified theory, even if it knows the existence of tachyons, what can it be used for?

In the current universe, there is no natural negative matter, all of them are artificially produced. This point is clearly recorded in the scientific and technological documents of the Merian civilization.

It is an interesting process that tachyons cause matter to increase. In this process, there is a paradox. That is, since the total matter of the universe is always conserved, it is also the law of conservation of mass-energy. Then, the negative matter composed of tachyons annihilates with the positive matter, causing the mass of the positive matter to disappear from the universe. How to explain this phenomenon?

You must know that the total amount of matter in the universe is constant, so if you create a negative matter of minus one kilogram and then use it to react with positive matter, causing the total amount of matter in the universe to decrease by one kilogram, is this phenomenon possible? occur?

Merlian Civilization's answer is that this phenomenon cannot happen. In the process of annihilation and annihilation of positive and negative matter, the total amount of matter is still conserved on the scale of universe and the macroscopic time scale.

The answer is simple, if you create minus one kilogram of negative matter, you will harvest one kilogram of positive matter at the same time. The total mass of one kilogram of negative matter and one kilogram of positive matter is exactly zero, so the process of making negative matter does not destroy the law of conservation of mass and energy.

Moreover, negative matter cannot be preserved for a long time, and will react with the ubiquitous positive matter in a very short period of time—no matter whether the positive matter that reacts with it is the positive matter associated with it, or the positive matter in the universe. The positive matter in other places is also good, in short, after it is produced, it will always react with other positive matter.

Its special surname makes it can be used to make weapons. Just like those giant cannons built on the surface of the planet. Those giant cannons are negative matter cannons. Xiao Yu has already seen their power. It is a huge power that can completely annihilate a provincial spaceship equipped with a four-protection cover in an instant.

Xiao Yu already knew the operating principle of that kind of cannon. First of all, a large number of negative mass tachyons were produced in the ground equipment, and after accumulating to a certain extent, they were shot towards the target at once. Because it is faster than the speed of light, it is unstoppable and cannot be warned. If the negative matter cannons are powerful enough, they can even annihilate a star in an instant.

What a majestic divine power it is to make a star disappear in an instant without any sign or movement!

Moreover, from the characteristic of negative mass tachyons, Xiao Yu also noticed an amazing possibility. That is, unlimited extraction of matter from the void.

The principle is very simple,

Since every kilogram of negative matter produced will be accompanied by a kilogram of positive matter, is it possible to launch it immediately after the negative matter is produced, and put the accompanying one kilogram of positive matter into the decay engine, so that Once you come, don't you have unlimited energy?

This inference made Xiao Yu excited. If this idea is really feasible, Xiao Yu will no longer have to worry about energy sources. However, Xiao Yu's excitement only lasted for a moment and then disappeared. Because, Xiao Yu immediately thought that in the Encyclopedia of the Galaxy, a common sense once mentioned, civilizations of level 6 and below are restricted in the river system, and the real reason why they cannot sail across the river system is still the energy limitation.

Even the mighty Taihao civilization, from the Large Magellanic Cloud to the Milky Way, had to follow the Magellanic Stream, relying on the material replenishment of the Magellanic Stream all the way to survive the distance of hundreds of thousands of light years. The Milky Way is more than two million light-years away from the nearest other galaxy, the Andromeda Galaxy.

From this, it can be speculated that since the fifth-level civilization has mastered the negative matter tachyon technology, then the sixth-level civilization will naturally have a deeper research on it, but the sixth-level civilization is still trapped in the river system, which proves from another aspect Xiao Yu's speculation is not feasible.

Xiao Yu continued to browse the scientific and technological documents from the Merian civilization, and soon found the answer: In the process of manufacturing negative matter, for every kilogram of matter obtained, it is necessary to invest more than one kilogram of matter into Energy of energy.

So that's the case. Xiao Yu resentfully got up. Just as it is impossible for you to extract the heat contained in a glass of 15-degree water into another glass of water with a temperature of 30 degrees without consuming extra energy, it is impossible to obtain endless energy through this technology. possible. Because in this process, the input must be greater than the output.

This is the negative matter tachyon. Dark matter is also introduced in detail in the scientific documents of the Merian civilization.

Xiao Yu didn't know until now what dark matter is.

Dark matter is still matter, but not ordinary matter. In the age of the earth, human beings have been puzzled by this question for a long time. At that time, humans discovered a phenomenon by observing the movement speed of galaxies in large galaxy clusters. In these large galaxy clusters, the movement speed of galaxies is too fast. According to observations, the masses of these large galaxy clusters are simply not enough to bind these high-speed galaxies, unless their masses are a hundred times greater than they are now.

Then there is an obvious problem. What are those invisible substances? They can contribute gravitational force, but they do not emit electromagnetic waves of any frequency band, nor do they react with any electromagnetic waves. They don't seem to contribute anything other than gravity.

In short, it is because of the discrepancy between the observation results and the calculation results that human beings are aware of the existence of dark matter.

Now, Molian Civilization has answered this question for Xiao Yu.

The answer of the Merian civilization is that dark matter is a special form of positive matter. Within the elementary particles that make up dark matter, there is no strong interaction force, no weak interaction force, and no electromagnetic force, only gravity.

Without the strong interaction force, quarks cannot be aggregated into basic protons, neutrons and other things, and matter cannot be formed. Dark matter is all composed of quarks, which are the clouds formed by quarks. Without the electromagnetic force, photons can penetrate them without hindrance, that is, they are invisible and cannot be seen by radiation of any frequency band. Having gravitational force means that they can still bend light, causing the phenomenon of gravitational lensing, which is perceived by humans.

Dark matter is ubiquitous in the universe. However, they do not have the characteristics of strong interaction force and electromagnetic force, which determines that they cannot participate in the decay of elements and transform them into energy, that is, they cannot be used. Because the basic principle of element decay is to cause the collision between quarks through the longitudinal strong interaction force and electromagnetic force, so as to generate energy.

Dark matter, it seems, is incompletely evolved matter. During their evolution, they seem to have only evolved gravity, but not the other three basic forces.

This conclusion made Xiao Yu feel a little regretful. If the ubiquitous dark matter in the universe can be used, then the energy problem that restricts the million-light-year voyage across the galaxy will be solved.

The scientific and technological documents of the Merian civilization also show that there is a certain magical connection between dark matter and antimatter, and negative matter serves as the link of this magical connection. When negative matter and ordinary matter meet, both of them will be annihilated. When negative matter and antimatter meet, after part of the mass of antimatter is annihilated, the other part of mass will be transformed into dark matter, an incomplete matter.

The four substances in the universe look like this... If I don't have these scientific and technological documents from the Merian civilization, but I just study it myself, it will take me at least a thousand years to obtain this knowledge. It seems that war and plunder are indeed the best way to promote the development of civilization.

Among the mechanical storage devices of the Merian Civilization, there are not many scientific and technological materials, and most of them are incomplete. As a result, although Xiao Yu can grasp these conclusions, he cannot know the derivation process, various formulas, etc. These things only pointed out a way forward for Xiao Yu, so that Xiao Yu could save thousands of years of development time. Xiao Yu had to do the specific research work by himself.

For example, before the appearance of Einstein, giving the formula E=^2 to scientists at that time and explaining the meaning of this formula clearly did not make much sense for the promotion of science, because the derivation process of this formula was lacking. Why this result is much more important than what is the result.

But this can at least point out a research direction for those scientists and save them a lot of energy and time, just like Xiao Yu is now.
