"The underworld has existed for a long time. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 infoAt least, we knew they existed a long time ago. Contrary to what you might think, they are not enemies to us, at least not at first. We can confirm that there are many myths and legends related to them...... This kind of thing probably doesn't need to be explained at all. ”

Fiedler seems to be intent on going into more detail, but Kazami Yuka, who already has some basic concepts of the underworld, is a little impatient. Sensing this expression, Mr. President smiled wryly twice, and as he continued, he tried to shorten the sentence used to explain it:

Contrary to the present situation, according to the account, in the early days they were helping us. They can be found in many places, and we can even infer their focus: they have a great interest in science and technology. This may sound confusing, but it's a true fact. There is ample evidence of the papal papacy's generous funding of scientific and technological progress – which, as you should all know, was one of the main sources of funding for scientific explorers in early human history. At least that's the case with Western civilization. ”

"The cornerstone of modern science itself was laid by Western civilization. Looking at Kazami with a somewhat apologetic look, Ackerman shrugged, but the latter didn't seem to care about such a thing, "But those people used to control the Holy See, did they want to control the humans?"

"No, of course not. They never seemed interested in politics or anything. It's like a ...... Well, it's like the attitude of parents towards their children. Most parents don't take the initiative to intervene in their children's conflicts, do they? And they do have a lot of things that we don't understand now. It's like...... Souls, ghosts and so on. ”

"Spirits and ghosts?" Echoing the two terms in a low voice, Ackerman shook his head in confusion, "Ever since I was reformed, that kind of talk has been far away from me. Will God save a body that is so filthy? Will a cyborg have a soul in it?"

"Don't worry, Mr. Ackerman, the Lord loves ......"

"If the 'Lord' in the mouth of Mr. President wants anything against you, I'll go and screw his head off. ”

Yuka's sudden interruption embarrassed Fidler. Scratching his nose slightly, he had no choice but to continue to talk about the underworld: "But the good times didn't last long, and this relationship between the underworld and us didn't last long. They started restricting us in some way and didn't want us to explore......"

"Aren't they encouraging and supporting us in the development of technology?"

"But there are some things they don't seem to want us to know," Fiedler said with a heavy sigh of regret in his eyes, "they don't want us to know about the universe." Not at all. ”

"The proposal of the 'heliocentric theory' was the first head-on conflict between us and the underworld, and it was also a sign of the beginning of a rupture between the two. The underworld does not want us to discover the correct model of the solar system, and the Holy See has carried out this will. What happened later, you can check the historical information for yourself, it is very clear. ”

"Copernicus' 'heliocentrism'?...... So, the theory of evolution is also what they are preventing?"

"No, of course not. After the controversy over heliocentrism, the underworld has almost disappeared from our view. The Holy See has also lost contact with them, and the opposition to the 'theory of evolution' is their own. There were once those who thought that the underworld had completely disappeared since the struggle of heliocentrism because of their disappointment with us. But history proves that they did not disappear......"

"It's hidden. ”

"Yes. And it is in the case of making full use of the original advantages. Nodding, Fiedler affirmed Ackerman's interjection, "They are infiltrating and stubbornly carrying out their convictions. Because of them, human astronomical research has been seriously lagging behind—extremely, extremely. After possessing nuclear weapons, they seem to have restrained somewhat, but the end of the Cold War marked their comeback. What's worse is that at some point, they also started some kind of hunt - we can't figure out what the hunt is, but based on the information we get from the struggle, they are trying to keep something out of our world......"

"Youkai. God. Magic. Immortals. All that has to do with that. "This time it was Kazami Yuka who interjected. Gently brushing her hair with her hand, her expression showed that the flower youkai still had little interest in the topic until now, "The creed of the underworld is not news among us youkai, although I don't know why. In the early days, it was still trying to control, but recently it has become so extreme that it must be obliterated. ”

"Thank you for the new information. Xiang Feng saw Yuxiang nodded, and Fiedler breathed a sigh of relief, "Humans naturally didn't sit still. The 'Free Masons', the most famous organization, was founded to break through the blockade of the underworld, although it was eventually defeated and poured with conspiracy theories. No way, they're too mystic...... In a sense, their attack on Lab 2 may be proof that research there is on the right path for astronautics. It's a pity that the core information is in the hands of Chinese......"

"In short, this is the underworld. Our current opponents. An organization that has infiltrated and is still trying to infiltrate our organizational structure, unswervingly opposing the development of our space technology and using extreme means to exclude the existence of 'unscientific' existence, while controlling the 'Land of the Dead'. After a pause here, Fiedler crossed his hands and stared straight at Ackerman, "I started purging them of infiltration as soon as I came to power, at all costs. That's why I'm being targeted. They are hindering our progress, and we must get rid of them, no matter why. I've said everything I know, so now,"

"Can you let me know your answer? You can opt out, it's not your fight. But at least, I don't want you to be on the opposite side. ”

The Demon of Laplace –

We can think of the present state of the universe as its past effect and as its future cause. If a wise man could know the forces of all natural motion and the position of all the objects of natural composition at a given moment, and if he could also analyze these data, then the motion of the largest object in the universe to the smallest particle would be contained in a simple formula. Nothing will be ambiguous for this wise man, and the future will only appear to him as it has been. ”

— for "omniscience."

Maxwell's Demon –

"We know that the velocity of molecules in a uniformly heated air-filled container is by no means uniform, whereas the average velocity of any arbitrarily selected mass of molecules is almost completely uniform. Let's assume that such a container is divided into two parts, A and B, and that there is a small hole in the dividing area, and that small hole is opened or closed in the context of a single molecule, so that only the fast molecules run from A to B, and the slow molecules run from B to A. In this way, it is in contradiction with the second law of thermodynamics that the temperature of B increases and the temperature of A decreases without consuming work. ”

- for "omnipotence".

For an "omniscient" "thing", turning back time does not seem to be a difficult task. Of course, these two thought experiments have been clearly and completely rejected: calculating the position of a gaseous oxygen molecule after 50 collisions with other molecules is enough to completely consume the amount of data that can be processed in all the time that has elapsed since the beginning of the universe, and the acquisition of information must also be done with the help of certain material processes, and with a certain amount of energy consumption, it is impossible to obtain information without consuming energy. "Omniscient" is itself impossible......

But if it is a fake "omniscient and omnipotent", for a well-developed interstellar civilization, it will be very simple.

"We're going back to the basics. What exactly are we talking about when we talk about 'going back in time'?"

"What the hell is time? Maybe it's 'what happens when nothing else happens.' This is nonsense...... We can't seem to give an exact physical definition of this thing. It's okay, there's nothing wrong with that. Let's just say what we know: time is how long we've been waiting!"

"Here's an important point. Time refers to 'how long we have been waiting'. It's a quantified concept of a segment, like 'length' – for the sake of directionality, we might call it 'displacement'. 'Displacement' itself cannot be 'backward', and there should theoretically be no concept of 'backward flow' in 'time'. But we're talking about 'going back in time'...... So what the hell is this?"

"So we had to introduce the concept of 'moment'. It's the quantity that T represents when everyone is doing a dynamic physics problem – that's not 'time', that's 'moment'. What does the moment represent? It represents the state that an object is in after a certain period of time has passed from the zero point of artificially defined time' – all states. Mass, Momentum, Position, Temperature, Acceleration...... All the quantities you can imagine that describe the state of an object, and all objects. All states of all objects: that is, the quantity t represents the property of the system itself, that is, the universe itself. In physics, it is the small universe that we construct that is completely isolated from the external system, and in our life, what T represents is naturally a state of the large universe in which we live. ”

"Moments are a state quantity. This is important, quite important. It is very important for us to reveal the truth about the scam in the future. ”

The observer may be in such a state of self-talk that means a complete mental breakdown, but the observer always thinks that he should do something. Outside, Auston is telling Ge Yiwei the truth in a different way of narrating. However, even if it is just to commemorate the days when he was an actor, and at the same time to commemorate him, he must use the way he taught at the beginning to tell everything slowly.

"So now we have a 'universe'. If the name is too big, we can call it 'system' – it's a little more pleasing to the ear. There is only one particle inside the system, the mass does not change, there is no volume, and there are no other troublesome state quantities such as temperature and charge. By the way, it also has a one-dimensional coordinates, in order to facilitate our discussion: thought experiments are so convenient, we can be whatever we want. ”

"This system has a state quantity t, obviously. In fact, there are only two quantities of state represented by t: the mass of the mass m and the coordinates. Let's assume that after the first second, t=1, the mass does not change, and the coordinates change from 0 to 1, and after the second second, t=2, the mass does not change, and the coordinates change from 1 to 0. Everything looks beautiful and normal. ”

"But! But! At this point we have an observer: just like me. For the observer, there is no way to distinguish between the moment t=0 and the moment t=2: there are only two quantities that can be distinguished, with the same mass and the same coordinates. To the observer, he waited for '2' – time did pass '2'. Does this indicate...... Is the process from t=1 to t=2 actually the process from t=1 back to t=0?

"In this way, the so-called 'time travel' to the 'past' is actually very simple, as long as we change all the states of all the matter in the system to the state of the moment we want to go to. Because it is impossible to distinguish between this moment and that moment, we can proudly claim that we are back in the 'past'!"

"But it can't be. You need to know all the states of all matter, the requirements of the Demon of Laplace, and you need to return all matter to its previous state, similar to the requirements of the Demon of Maxwell. Neither is possible. But let's not forget our premise: it's a scam! We don't need to make the moment really go back in time, we just need to make the 'participants' think they're back in time!"

"At this point, the composition of the scam is simple. Only two key steps are required: "

"First, it limits their perception of the amount of state in which they are judging at all times. It's okay to feel that time is moving forward, it's okay if the decayed particles don't change back, and on the psychological time arrow, about the 'macrocosm' of a star system is enough to fully suppress these insignificant things. The psychological reversal of the arrow of time is enough to inhibit the perception of the cosmological and thermodynamic arrow of time, confusing them, and believing in the set of things that are deliberately used to mislead them with the truth and the truth of the two...... For this, what we need is a remote galaxy with poor information exchange, almost no main star map and a blockade of the galaxy;"

"Second, store and control the amount of state they depend on. We don't even need to go through a lot of trouble to adjust every particle in this galaxy. We just need to do a rough idea: using the psychological model provided by Bharotigo, it is very simple to judge how to make them subjectively indiscerning. The trouble is that we also have to 'mark' all the masses in the galaxy so that we can know what is in what state at what time and what needs to be changed. That's the scam. In other words, what the participants of the 'Reverse Stream of Time' do is: "

On the moon, facing the iron-faced Ge Yiwei, Auston slowly said the final conclusion:

"Immediately hibernate the participants, completely destroy and obliterate the world. Then, the data is extracted from the enclosure to create a world that closely resembles 'the world of that moment.'" It doesn't need to be exactly the same, as long as the participants don't notice it: just a galaxy, a radius of a light year, is not too difficult for the alliance that created this scam, and even the planet's topography does not need to change much, the main job is to kill creatures and destroy artifacts, clone creatures and create artifacts, and finally put them in place. Finally, wake up the participant, carefully place where he should be, and 'start' the world. ”

Again, this is a scam. A subtle scam. Its designers never thought about really turning back time from the very beginning. They just want to make you think "time has gone back".
