a certain scientific hogwarts

When Meryl confirmed the distress message records in the chat group and confirmed Hans' statement, she no longer stopped Hans from going to bed early.

"I think Hans has been too depressed recently. Although Master Lin used magic to expel those negative energies, his mental condition is still not healthy." Meryl said to John, "From his recent past These irritable moods and obvious sense of isolation can be seen. I think he should be allowed to stay with his parents for a period of time every day. Anyway, there is magic. It is not troublesome to ask them to come home and live there, and teleport to London every day."

"The two of them are children themselves... Although what you said makes sense. But don't have too high expectations for them." John was very disappointed that the two of them had not yet returned home to look after their children. "Ignore this, I will go to the city tomorrow. When I get home, Hans will not be reminded of what happened after he fell asleep. Moreover, with the communication magic, we can still talk to him even if he falls asleep during the day. With skillful Ask frequently and just treat it like small talk."

"What are you doing in the city?"

"Buy some musical instruments. Although I haven't played them for a long time, you and I can use the guitar and violin after getting familiar with them. Didn't you say before that he likes music? He thinks about those magical things all day long and can't get involved in the rush. It's better to let him go and wait for him. Ask what you should do if you can’t handle it.”

"Well, you're right. We're tired of worrying about you and the kids." Meryl thought for a while, "Don't we still have the old piano and my cello in the warehouse? I'll give Mike a call later and ask him to go there tomorrow. Go to the piano store and hire a piano repairman and tuner. I'll ask Linglong to sort out the furnishings in the living room later with magic, and remove the useless decorations that take up space. For the banquet next weekend, there will be room for musical instruments in the living room. A bit small…”

"The weather this month is not suitable for outdoor dining in the yard. After finishing the musical instruments tomorrow, I will ask Hans what he thinks about his birthday party, and then discuss with the wizards to see if there is a solution. I think their magic is there Places like this kind of party are very useful. If you can learn them individually, most of them are essential skills for science and engineering technicians." John shrugged, making Meryl laugh.

Hans, who fell asleep again, took the three maids back to their world.When Hans came here again, he found that the barrier of the Snack Witch was covered with other barrier-like things outside, just like the way Akatsuki Homura was trapped in Rebellion Story.

"What unreasonable things did you do when you came in? That you couldn't even get out?" Hans smiled widely as he looked at the embarrassed people in the alien world.

"The magic similar to the word spirit you used before has been feeding the witch non-stop... We couldn't get any useful information, so Ancient One returned their time to before you released the word spirit." Odin explained awkwardly , "After she finished it, there were too many annoying kittens, and I didn't bring any weapons or armor..."

"So you guys, the big guys from all the worlds, were accidentally abused by a group of cats in this world!" Hans smacked his lips, "Why didn't Gu Yi open the door and leave?"

"When I was about to leave, the shell outside blocked the space magic energy... The magic and rules of this world are really weird and weird..." Gu Yi smiled bitterly.

"What about you guys?" Hans was curious.

"Similarly, I didn't dare to take action at the beginning. I was afraid that if I ruined the world, you would be very angry. When I wanted to take action..." Inhibition rushed to answer...

"So you should stop resisting. This will trouble me a lot." QB's voice sounded outside the barrier. "We just ask you humans to give a small part of yourself to provide the entire universe--"

"Shut up. Stop using your nonsense theory of heat death to fool little girls as an excuse." Hans said to the incubator disdainfully.

"I'm not lying."

"You use scientific theories as an excuse, but in the end you use metaphysical methods as the solution to energy collection. You have metaphysical methods, why don't you use it to directly change scientific results or even scientific rules?"

"We can only enable the wish-making tool, but we cannot make wishes ourselves."

"You only need one magical girl for your purpose, just ask her to make a wish to help you realize the result. If you are not capable enough, it is just a little bit worse to make a wish to directly accumulate enough energy for you. But you have created so many magical girls. You talk about sacrificing only a small part. After you collect the energy, you let the remaining witches on the earth destroy humans. To put it bluntly, you still use humans as consumables and kill them after they are consumed. It is not you who do it yourself, but you are still yourselves. Creation. Let me change your concept. No matter the purpose or the way you act, it is completely different from your excuse. This is not something that has no emotions and different values ​​​​that can excuse you. Your wishing tool can make magic The girl interferes with the virtual dimension of time, but you say that you have no way of interfering with the second law of thermodynamics. Who are you fooling? The second law of thermodynamics may not apply to living things or the world as it rises and falls in different dimensions. The virtual dimension of time spans many The existence of dimensional space." Everyone looked at Hans in confusion, and the words "What are you talking about" clearly showed on their confused faces.

“The theory of heat death is a conjecture about the ultimate fate of the universe based on the second law of thermodynamics.

The second law of thermodynamics is one of the basic laws of thermodynamics, also known as the law of entropy increase. It states that the degree of disorder of an isolated system will only increase or remain unchanged.

After the establishment of the second law of thermodynamics, scientists discovered that when the second law of thermodynamics is applied to the entire universe, the entropy of the entire universe will continue to increase, and the temperature throughout the universe will gradually tend to be balanced. Eventually, all other effective energy in the universe will be converted into heat energy. , thus reaching the heat death state, which is a rather long process.

Currently, the dominant celestial bodies in our universe are stars, but the nuclear fusion reaction of stars proceeds in one direction. One day, the last star will be extinguished due to insufficient nuclear fusion material, and then the universe will plunge into endless darkness. , Black holes dominate the evolution of the universe, but black holes themselves also have a lifespan. When the black holes evaporate, it will be the end of the universe.

The heat death theory is a direct corollary of the second law of thermodynamics, but some people have raised doubts. The heat death theory only simply considers the influence of the second law of thermodynamics. However, our universe is in a dynamic state and is currently accelerating expansion, coupled with the effects of gravity and The effects of quantum mechanics simply cannot reach equilibrium, so heat death cannot be reached.And according to the Big Bang theory, it is possible that the universe will transition from expansion to collapse in the future. Perhaps our universe has experienced countless inflations and contractions, and I just happened to be in the midst of this expansion.

However, the theory of heat death does have a certain theoretical basis. If the effects of quantum mechanics are taken into account, then the future of the universe is related to the decay of protons. The current half-life of protons predicted by human theory is 10^36 years; then in theory, as long as the time is long enough, the protons will It will all decay, and all the matter in the universe will be sucked into the black hole. Then the black hole will lose mass through Hawking radiation. In the end, only photons and leptons will exist in the universe. This is also a heat death state. "Hans explained helplessly as he looked at everyone.

"These little beasts just use humans as food reserves and guinea pigs. Most of the high-sounding claims are nonsense. This kind of species that cannot even move upright is not suitable for scientific research no matter how intelligent it is. Innate Biological defects. It is estimated to be a low-dimensional creation of a higher-dimensional creature, a scavenger that prevents the rise of species that have the opportunity to ascend to another dimension and pose a threat."
