Super Battleship Reborn

After this message, there is no message from the Torol civilization, and the message from the Tolor civilization ends here.

Xiao Yu was shocked by this news.

Ten years, only ten years...the principle of entropy increase, heat death? Xiao Yu thought quickly, and these words flashed through his mind quickly.

Xiao Yu clearly knows what the principle of entropy increase is, and also knows the great influence of the principle of entropy increase on this universe. It can be said that it is precisely because of the existence of the principle of entropy increase that time will not flow backwards, and the universe has been shaped into the current state.

Entropy is a value that measures the degree of chaos in the distribution of matter in a system, and it was born from the second law of thermodynamics. The concept of entropy can be illustrated with a simple example. Everything in the universe has its own entropy value, a teacup has its own entropy value, a pen has its own entropy value, even a computer, a human being has its own entropy value.

Entropy can be divided into big and small. A newly built house has very low entropy because it is neat and orderly. A dilapidated, dusty house that has not been cleaned for a long time has a higher entropy value than a new house.

Entropy is such a thing, the entropy value of a broken cup is higher than the entropy value of a good cup, the entropy value of a broken computer is higher than the entropy value of a new computer, and the entropy value of a rotting corpse is higher than that of a living person. High entropy. In short, the more dilapidated and chaotic the structure of a thing, the higher its entropy value.

And within an independent system, the entropy value can only increase, not decrease. So a broken cup will not become a good cup, a broken computer will not become a new computer, a dead person will not become a living person, and time cannot be turned back.

Of course, a broken cup can be repaired to make it better again, and a broken computer is not inferior to a new computer after repairing it. Even, if you master the cloning technology, you can clone a living person from a dead body, but there is one thing to pay attention to. The concept of entropy is for an independent system. Now that it has been patched, and with the intervention of external forces, it is no longer an independent system.

According to the principle of entropy increase, if you don't clean a room, it will only become more and more dirty. It is impossible that if you don't clean it, it will become cleaner and cleaner. If a house is regarded as an independent system, without the influence of all external conditions such as gravity, external energy, and external organisms, as time goes by, this house can only become more and more chaotic. The white ash will fall off, and the house will collapse. In the end, all the substances that make up the house will spread evenly in this system. At this time, its entropy value will reach the highest.

This is the principle of entropy increase. For example, our universe is an independent system, so the ending of the universe will inevitably be heat death. After countless years, there will be no stars in the universe, all stars, planets, comets, white dwarfs, neutron stars, and even For a black hole, everything will disappear, and the universe at that time will be filled with infinite leptons and photons.

This is the inevitable end of an independent system.

The principle of entropy increase? Will this small universe dissipate? Xiao Yu felt a faint bad feeling in his heart.

According to the Tollor civilization, this small universe will die within ten years...all the matter inside it will disappear. Could it be that the speed of entropy increase has something to do with the size of the universe? The entropy is too large, so the entropy increases slowly, and this small universe is too small and unstable, so the entropy increases very quickly, reaching the highest entropy within ten years?

Xiao Yu began to worry in his heart, because Xiao Yu also thought of another possibility.

That is, time.

I don't know if the time of this small universe and the big universe are synchronized,

I have been here for almost a year, and I don't know how much time has passed in the real universe. Since the entropy value increases rapidly in this small universe, does that mean that the passage of time is also faster than in the large universe? If I stay here for a year, the time in the universe will pass a million years, that would be bad. One million years is enough for the sweeper civilization to recover, and it is also enough for the guardian civilization to restore their health. flagship. At that time, the Milky Way did not know what would become of it. I hope such a thing won't happen... Xiao Yu prayed silently in his heart.

Worries about this matter even temporarily overwhelmed curiosity about space weapons.

We must hurry up. Xiao Yu thought silently, and quickly transferred the space weapon technology taught to him by the Tolor civilization into his mind, and began to watch.

Finally got the most important one of the legacy of Tollor civilization, but Xiao Yu didn't feel any excitement in his heart. If you have a life to get it, you also have a life to enjoy it. Xiao Yu doesn't think that with his current technology, he can resist such things as entropy increase and heat death.

Judging from the history of the Tollor civilization, this small universe has existed for at least half a million years, so there is no reason why it has maintained stability in this short period of ten years. There is only one explanation. In the past half a million years, the program left by the Tolor civilization must have been continuously obtaining energy from the universe, relying on external forces, Only then did the continuous weakening of this small universe system be prevented.

In this way, perhaps the emptiness of the entrance galaxy of this small universe can also be explained. All the matter in this galaxy, except for the star that is too big to handle, the rest of the planets, comets, asteroids, etc. , should have been brought into this small universe by the Tollor civilization and turned into energy. Xiao Yu thought secretly.

In this case... Xiao Yu suddenly had another thought in his mind.

In fact, according to the laws of physics, time is not irreversible. Time is just a virtual concept. It is a value to measure the movement of matter. When a person walks from the door to the school, he spends five minutes. If the person walks from the school to the door and returns to the original point, then it is not Could it be considered time turned back five minutes?

This example is somewhat imprecise, after all, in our world, besides this person, there are many other substances, with wind blowing and cars moving. Then to simplify this example again, if there is only one elementary particle in the universe, assuming that this elementary particle itself will not undergo any changes, and there is no other matter in the universe except this elementary particle, this particle will never change. It took five minutes from point A to point B, and then it returned from point A to point B, and everything returned to the original point, so did the time go back five minutes?

Some people may say that time has not flowed back, but time has passed. But after this elementary particle returns to the origin, everything in this universe is exactly the same as it was five minutes ago, so why can't it be said that time is running backwards?

This example is a bit extreme, and of course it doesn't happen in the real world. But even in the real universe, there is still a way to go back in time. At this moment, Xiao Yu thought of such a way. Of course, whether it can be realized is another matter.

Although the principle of entropy increase shows that the time of an independent system is irreversible, none of us can be sure that our universe is unique. It may not necessarily be true that other universes will exist. In other universes, there may also be a large amount of matter and energy. If one day, energy can be obtained from the rest of the universe to subsidize our universe, then the entropy value of our universe may be reduced, and when the entropy value is reduced, time may be reversed. Just as the intervention of human power will restore the room from dirty to tidy, the intervention of human power will restore the broken cup to its integrity.

A civilization that can do this must already be a god-like existence. Don't even think about level six civilizations. If... I mean, if, one day, I can reach this level, I will bring this great universe out of order and bring It is not impossible for everything to return to the original point and bring the earth back to the human age. Xiao Yu thought to himself, Such ability must be only available to civilizations of level seven or above. Logical weapons... I don't know what the mystery of the seventh-level civilization is.

Reversal of time and logical weapons, these are the two abilities that Xiao Yu speculates that civilizations of level seven or above may possess.

Shaking his head secretly, throwing the chaotic thoughts out of his mind, Xiao Yu continued to study this information carefully.

The result made Xiao Yu a little disappointed. Originally, Xiao Yu thought that he could peek into the mysteries of the space technology of the sixth-level civilization from this technical document, paving the way for himself to step into the sixth-level civilization, but now Xiao Yu discovered that he did not want to thought about it.

Because this technical document is of the same nature as the ghost detector that Xiao Yu once obtained, it only explains the method of manufacture and use, and its application principle, technical details, and scientific and technological theories are all absent. In other words, with this technical document, Xiao Yu can create and use space weapons, but there is no way to make even the slightest change to this space weapon. Because Xiao Yu didn't know the manufacturing principle of space weapons.

People, don't be too greedy. It is enough to have this kind of weapon. You might as well study its principle in detail in the future. Xiao Yu thought to himself, dispelled the little unhappiness in his heart, and began to follow the guidance of the technical documentation to manufacture The first level 6 civilization weapon that he owns, splits the space.
