"The concept of entropy originated in physics as a measure of the degree of disorder of a thermodynamic system. Dr. Li said slowly: "The second law of thermodynamics, also known as the law of entropy increase, states that the total degree of chaos of an isolated system, i.e., entropy, does not decrease in natural processes. Einstein's view is that the law of entropy is the best of the laws of science. ”

Ge Wei nodded, he really hadn't heard of entropy, and he didn't know much about the second law of thermodynamics or anything. It's all because he sleeps in physics class......

"We know that energy, materials, and information are the three basic elements of the material world, and among the laws of physics, the law of conservation of energy is the most important law, which shows that when various forms of energy are converted into each other, they are always immortal and maintain balance. Dr. Lee lifted the lenses on the bridge of his nose that didn't exist, and once again lost himself in thought, perhaps because he often wore reading glasses to read, "Energy is arguably the most important thing in the universe as we know it. Since the birth of the universe, energy has been pervasive in the universe, all-encompassing and omnipresent. Energy manifests itself in many different forms, and as far as we know, there are no less than dozens. They all follow the law of conservation of energy and strictly follow the principle of immortality balance. Entropy, on the other hand, plays quite an interesting role in this process. ”

Dr. Li looked at Ge Wei: "First of all, you need to understand these three points: entropy is originally a state parameter of matter that reflects the irreversibility of spontaneous processes according to the second law of thermodynamics. The second law of thermodynamics is a natural law summarized from a large number of observations: first, heat is always transferred from a hot object to a low temperature object, and it is impossible to transfer it in the opposite way without causing other changes; second, work can be converted into heat completely, but no heat engine can completely and continuously convert the heat it receives into work, that is, the reason why it is impossible to manufacture a second type of perpetual motion machine; and third. In an isolated system, the actual process always increases the entropy of the whole system, which is the entropy increase principle. ”

The corners of Ge Wei's eyes twitched, his forehead was beating wildly, and he said in his heart that he should really take physics class.

Dr. Li: "@#¥@#%^$%&......$*!~"

Ge Wei supported his forehead......

Dr. Li:"$%&......$*@#%^!~#¥@"

Ge Wei continued to support his forehead......

Half an hour later.

Ge Wei suddenly said, "Ugh. Does this mean that as long as you are in an isolated environment, the entropy will increase, and the higher the entropy, the more chaotic and disorderly?"

Dr. Li finally wiped the sweat from his forehead: "You finally understand...... Yes, basically. In isolated or adiabatic conditions, the direction in which the system proceeds its spontaneous process is always in the direction of increasing entropy until the entropy reaches its maximum. At this point, the system reaches equilibrium. ”

Ge Wei nodded, finally understanding the concept. But he still has some doubts, what does this have to do with parallel universes?

Ge Wei asked the question.

Dr. Lee thought for a moment and replied, "This can only be said to be a corollary, and I think that entropy is the key constant behind the universe." The expansion of the universe is not only an expansion in the sense of distance, but also an increase in entropy in thermodynamics. According to modern cutting-edge theories. The universe has multiple dimensions, and the fifth dimension is invisible to us. Because it's microscopic. We can assume that each multidimensional universe triggered by a single possibility will be in this isolated and closed system, resulting in an increasing entropy of the universe as a whole, and eventually the system will become chaotic and disorderly. Because the entropy of the system directly reflects the uniformity of the state it is in, that is. The smaller the entropy of the system, the more ordered and uneven the state it is in, and the larger the entropy of the system, the more disordered and uniform the state it is in. The system always tries to spontaneously transition from a state with less entropy to a state with a higher entropy value. From order to disorder. Eventually, the universe we observe will tend to be in equilibrium, and the whole system will be infinitely close to equilibrium. ”

Ge Wei thought seriously for a while, and then asked, "So, what will happen when entropy reaches the maximum and the universe reaches the apex of disorder?"

Dr. Lee shook his head and said, "Theoretically, it can't happen, the whole system will just tend to equilibrium infinitely and become infinitely homogeneous." ”

Ge Wei seemed to think of something and nodded.

In other words, without interference, the Great Plane will always progress in the direction of chaos and disorder. It makes sense how there are so many derivative universes. The Great Plane is becoming more chaotic all the time.

After pondering for a while, Ge Wei asked again: "Is there a way to reverse this process?"

Dr. Li was stunned when he heard this, he didn't expect him to ask such a question, and asked a little stunned: "Reversal?"

"Yes. Ge Wei faintly felt that the breakthrough point of everything was at this key place, "Reversing the growth of entropy, reducing the entropy of the entire system, and bringing the universe back to order! Is there a way to do this?"

Dr. Lee laughed and said, "Theoretically, it's doable. The direction in which the system proceeds to the spontaneous process tends to increase entropy, provided that it is in isolation conditions and isolated systems. If there is a way to influence this isolated system from the outside, yes, it can cause the entropy to stop increasing, or even decreasing. Thus reversing the process and bringing order back to order in the universe. But well, the entropy that affects the entire universe increases, which ...... It's unlikely, hehe......" The implication is that even if it is theoretically feasible, only the so-called gods can really do it.

Ge Wei looked more focused and thought about it.

Ge Wei knew that there was one thing that Dr. Li was wrong about. That is, the higher dimensions are not microscopic, on the contrary, the planes are macroscopic. Dr. Li only knows the most basic concepts of multi-dimensionality, but he does not know what state is on top of the concepts, including the entire plane of the universe. It's like an ant seeing an elephant, but it can only see a huge shadow, but it can't see the whole picture of the elephant. There is no way to draw deeper inferences about elephants.

But at least, Dr. Li's theories have made Ge Wei understand that the real reason for the continuous proliferation of derivatives is the natural deduction of the large plane, which is an inevitable result. And this kind of natural deduction, although it cannot be directly avoided, there is a way to interfere with it. Ge Wei knew that Qingdao Chufu was trying to find a way to reverse this process.

New question: What is the reversal method?

By killing other tokens, this process can be reversed?From the fact that Qingdao Chufu continued to find ways to hunt the tokens, Ge Wei had to speculate that this should be the right way. Otherwise, Qingdao Chufu would not have spared no effort to do so. Qingdao Chufu must have gotten a reversal method from Dr. Li on his side.

As for what the outcome of the reversal would be, and what motive Qingdao Chufu had for doing so, Ge Wei threw the question to Dr. Li again, hoping that Dr. Li could answer it for him.

Ge Wei thought about the wording and asked a question that puzzled Dr. Li.

"Suppose there are some parallel universes, and someone in one of them tries to kill himself in the other universes, Dr. Lee, what do you think is his original intention?" (To be continued......)
