Chapter 32 Part Thirty: The Lost Traveler—Part Two: The Problem of Compression

In the evening, the "time traveler" left temporarily, but I stayed at a friend's house. Me: "Do you think he is mentally ill?" The friend was a little anxious: "Are you asking me? I came here to ask you this!!" Me: "Don't get excited... because I don't understand the universes and bubbles you mentioned, so I can't make a judgment. Please tell me whether what he said belongs to the category of novels and movies or is it true That's it." Professor of Quantum Physics: "Oh, that's it, um... I don't quite understand some things. For example, when it comes to the problem of anti-gravity devices. He mentioned gravitons, this... Because gravity is just a phenomenon, why is there universal gravitation, universal gravitation The cause of it is still unknown.”

Me: "...Yes, why is there gravity..." Professor of Quantum Physics: "No one knows now. The existence of the gravitational field is a fact. So what he mentioned is really interesting. If the so-called graviton is really discovered, the anti-gravity device is really possible. That can be said to be a major event. technology mark." Me: "Is there any more? And do you think it's nonsense?" Professor of Quantum Physics: "It's hard to say. I think I will ask him in detail when he comes tomorrow. If it is what he said, then as a participant, he must have some knowledge about that aspect, even if it is pre-job training. Knowing something, it is impossible to let it go without knowing anything, which is contrary to common sense. And he also mentioned that this is a government action, so there should be pre-job training. I think this is a very important point. Because currently I In the knowledge of quantum mechanics, I have never heard of this kind of transmission method. Even if he can give a general idea, it is theoretically feasible...otherwise it is just nonsense."

Me: "Wait, you mean you believe what he said?" Professor of Quantum Physics: "Well... a little bit, so I am in a hurry to confirm with you. Because in terms of traveling through quantum foam, the current technology is still in the experimental stage, such as unconditional teleportation - that is, unconditional transmission of a thing here in my home To your house. Although it can be done at present, it can only transport very small particles..." Me: "Stop, electricity is too complicated, and what's the multiverse theory? If I don't understand it, I can't tell if he's talking nonsense. You have to teach me tonight."

He scratched his head vigorously: "How is this possible?" Me: "Otherwise I can't help you." He thought about it seriously for a while: "Well... I'll try... But I can only say my best... Where have you been listening to the lectures?" I admitted frankly: "Fall asleep." He sighed: "Come to my study." I found it very cool to have my own study room, whether I read books or not, the atmosphere is quite good.At least it sounds awesome. After sitting down, he looked at me seriously: "You are testing my teaching level... Let me see if I can compress the most essential content and explain the multiverse theory to you in the most straightforward way."

I bowed: "If it is really possible, then I will listen to your class in the future." He smiled: "Well... let's start with this: In the 19th century, there was a consensus in the physics world that energy like light and electromagnetism exists in the form of continuous waves. So we have They are all using terms like light wave and electromagnetic wave. For this point, it is a great achievement in the physics world in the 19th century. If someone doubts this, it can be confirmed by an experiment.” Me: "Well, what to do with a bunch of instruments. In the end, I came to a conclusion, and everyone was dumbfounded. I understand that."

Professor of Quantum Physics: "You are wrong, this is a very simple experiment, anyone can do it." Me: "Hey? Really? Then show me now!" Professor of Quantum Physics: "Don't worry, I will do it for you. Let's talk about the first step first: Suppose, suppose you make a vertical slit on my door, and I stand outside and use a flashlight to look inside. Shine, you turn off the light and watch in the room. There will be a light band on the wall, right?" Me: "Yes, what's wrong?" Professor of Quantum Physics: "Okay, now suppose there are two vertical slits on the door, and I still stand outside and use a flashlight to illuminate, how many light bands will you see on the wall inside the room?"

Me: "2 items, is there a problem with this?" He smiled: "Really? Let's try it." He found a piece of hard paper, cut two narrow slits with a paper knife, and turned out the flashlight. I looked at him puzzled and asked: "Isn't it two?" Before turning off the lights, he smiled mysteriously: "Just look at it." He turned on the flashlight and blocked the beam with the cardboard with two slits.A series of gratings appeared on the wall (see Figure 1).I exclaimed like an idiot: "Oh my God, there are so many!" Quantum Physics Professor: "See?"

Me: "How could this be?" He turned on the light in the room again and sat back in front of me: "The light waves passing through the gap are coherent, superimposed on each other in some places, and then what you see is a series of gratings with light and dark effects (see Figure 2). " Me: "That's interesting." Professor of Quantum Physics: "Let's still assume that if the door is pulled out with 4 gaps, how many light bands will there be on the wall?" Me: "Uh, let me do the math...doubling plus stacking..." Professor of Quantum Physics: "Don't forget, the grating obtained in this case is only half of what it was just now."

Me: "4 slits have fewer light bands than 2 slits? Are you sure? Why?" Professor of Quantum Physics: "Don't you believe it? We can do the experiment again." Me: "No, I believe it, tell me why." Professor of Quantum Physics: "Because there are too many slits, the light waves cancel each other out and interfere with each other. This is the phenomenon of light interference. This experiment is called 'Young's double-slit interference'. You can do this experiment as much as you want when you go home. " Me: "Well, I might. But what does that have to do with the multiverse?"

Professor of Quantum Physics: "Yes, the experiment proved that light is a wave, but there was a small problem later: when the metal plate is illuminated with light, a current will be generated. No one knows why. Later, after trial and error, by studying the amount of light on the metal plate and the relationship between the amount of current generated, a conclusion has been obtained." Me: "What's the matter with the relationship between light and current? A series of calculations?" Professor of Quantum Physics: "Yes." Me: "Okay, don't tell me those formulas or calculations, just tell me the result."

Professor of quantum physics: "Well, if you are interested, you can find out; the result is: light is actually energy in the form of continuous independent units, that is, a particle. This is the beginning of quantum physics." Me: "...What about Yang's experiment? Was it overthrown by mathematics?" Professor of Quantum Physics: "It seems to be true, because it is unreasonable. Then physicists started to argue, but no one can deny it-because this is not a matter of talk, the calculation process is there, there is no falsification This confusion did not end until Einstein published his research on atoms and particles. Einstein called the particles of light photons, and it was precisely because the photons hit the metal plate that the current was generated." Me: "The light wave experiment was done in vain? What a toss, it was a pseudo-scientific experiment after a long time. I was excited for nothing, thinking that I could finally make a scientific experiment myself." He smiled: "It's not in vain. Up to now, it has been proved that photons are particles with wave characteristics." I looked at him confused. Professor of Quantum Physics: "Let's put it this way, because photons are fast enough, and they are still continuous, do you understand this? It's like throwing a handful of sand." Me: "Hey, I should have said it earlier... It's OK here. But you have said so much, and you didn't mention the multiverse issue." Professor of Quantum Physics: "This is what I want to say. Through the previous experiments, you have seen the mutual interference of light, that is to say, light can interfere with light. Later, the problem of photons was confirmed. The following is the evidence of the multiverse theory one of them." Me: "OK." Professor of Quantum Physics: "Physicists think: If a photon is emitted each time and a special light sensor is used to receive it, then there will be no interference, right? Because the speed of the photon allows it to be free from interference—because there is no Another photon." Me: "Well, that's right." Professor of Quantum Physics: "But the experimental results are incomprehensible to everyone. The landing point of the photon is very unpredictable. This time it is here, the next time it is there, and the next time it goes to nowhere. There is no formula." Me: "Well...if you calculate the probability." He shook his head: "Don't use mathematics, this is a real experiment, real photons, real sensors, a few kilometers deep underground, all the factors that can be ruled out. However, there is no formula." I laughed: "Then the physicists fought again?" Professor of Quantum Physics: "That's right. Everyone is doing this experiment, but no reason can be found. All known possibilities have been ruled out." Me: "Finally this is the end. You want to say: Photons from other universes interfere with this photon? Well, I believe it for the time being. Then, how did it interfere?" Quantum Physics Professor: "Remember Quantum Foam?" Me: "...that's it...but..." Professor of Quantum Physics: "That's right, it's the 'but' you said, so the issue of multiverse is still being debated. Because there is no problem in that experiment, but there is no answer, and only multiverse can explain it. Moreover, no one can It proves that this statement is wrong. However, this completely overturns many things we know so far: soul, god, physics, this explanation is too bold, and it has reached the point of unimaginable." I collapsed on a chair exhausted - finally figured it out. When I lay down that night, I felt a little dizzy because so many things had rushed in during the day.So much so that it took me so long to fall asleep. the next day. My friend was also sitting next to me with a tired face, while the "traveler" looked calm and collected. Me: "I want to ask you, did you go home yesterday?" He's right." Me: "What's the difference between here and yours, except for that anti-gravity device?" He: "Your South America is independent of more than a dozen countries. On our planet, South America exists in the form of an alliance, just like the European Union." Me: "Oh? How long has it been like this?" He: "It has been in preparation for many years, and it has been established for more than a year." Me: "Oh, the President of the United States is Bush?" (2006) He's right." Professor of Quantum Physics: "Can you tell me how your anti-gravity device creates gravitons?" He: "Manufacturing? No, not manufacturing, but changing the direction of the graviton." It can be seen that the professor of quantum physics was a little surprised: "Hey? Do you know how it changed?" He: "I don't know about this." Me: "Okay, then tell me you know." He: "Well, I will say as much as I remember. If you think that what I said has serious problems and is really mentally ill, tell me right away? I mean it." I nodded. "No problem; can you talk about the transmission?" He: "Okay, I know a lot about that." The professor of quantum physics quickly grabbed the notebook and pen in my hand and prepared to write down his important points. He: "When we talk about transmission, we must talk about the brain and the human body. After we successfully understand the function of the brain through DNA technology..." Me: "Stop, you said that you have completely cracked all the functions of the brain?" He: "All? I didn't say that, did I? Mostly, but the memory part basically has no problems." I exchanged glances with the professor of quantum physics: "Okay, you continue." He: "After understanding the function of the brain, biologists found that many functions of the brain cannot be fully understood without interaction with the body, so they began to virtualize the human body." Me: "Virtual? Uh, if I understand correctly, it is to completely simulate the human body on the computer, right?" He: "Yes." Me: "That's impossible. The human body's cells are too large. No computer can run them. Maybe they can scan them, but they must be converted into information and operate according to the functions of the human body. That's impossible! Don't say that your earth has any black hole information. computer or quantum computer." He: "We don't have the one you mentioned, but we still have supercomputers, maybe similar to yours, and it won't be much worse, but we did it, using compression technology." Me: "You haven't finished talking about the compression of the mind, and now you mention the compression of the human body? Okay, very good, how did you do it?" He smiled confidently: "For example: you took a photo of a blue sky, a piece of blue, right? If you zoom in on the photo, you will see a lot of pixels arranged together. Each pixel The blue is definitely different, each pixel has its own independent information. The better the function of the camera, the more pixels, so that the blue sky looks more realistic. But the capacity of this photo will be huge..." Me: "Vector illustration?" He: "Yes, that's what it means. But if this photo does not need to be enlarged so much, as long as it is expressed, those pixels will be compressed technically. For example, if this pixel and the pixel next to it look Almost, then there is no need to store two pixels, and express them with one piece of information. If the pixels of this piece look similar, then turn this piece of pixels into one. In this way, according to the required clarity , to compress all those pixels. The capacity of the photo will be many times smaller. If you don’t need to enlarge a lot, you won’t be able to see it at all. This is pixel compression technology. We use this technology. Combined into one message. This is much easier. For example, epidermal cells, we record a message in units of one square millimeter. Or record one square millimeter of liver cells... and so on. The same is true for brain cells, but the accuracy can be improved Some, such as a tenth of a millimeter as a basic unit? This can be compressed. Although the amount of information is also large, it is much better than each cell as a unit." Quantum Physics Professor: "A Scanning Instrument..." Me: "Uh, it's not a big problem. We can also use MRI to assist in X-rays at the same time. Although it takes a little time, it can be done. But those equipments are definitely not of the hospital level...but... I turned to "Traveler": "But if the sample cells are unhealthy and potentially dangerous, wouldn't that be the end of that piece?" He: "I know this, but we don't have to pay attention to whether some individual cells are unhealthy. After all, we don't want to recreate a body, just simulate it. Use the simulated virtual body to connect with the main nerve of the brain. The interaction with the brain may not be so perfect, but it doesn’t matter, because the purpose is not perfect, as long as the weak electrical stimulation, nerve reflex, the brain can work according to our requirements. Then stop other intelligent reactions, and only keep the life support function, and a relatively peaceful brain state is obtained. At this time, stimulate the memory part of the brain, let the memory part release the weak electricity of that part, extract the memory information, and then use the electrons to send it here instantly according to the mode of the brain itself. A strong signal is added to the part for positioning, and a return timing memory is added to the end part, as if transmitted online. So I am here." We were flabbergasted because it was perfectly possible—except for the sending behavior part. Me: "...Is that so... Then you just need to remember it... Then your earth will cure amnesia will be fine?" He: "Yes, that's right. Then talk about me, I know what I am here for, what I want to do, that's enough. As for whether my heart is not as good as that over there, or my nails are longer than here If it’s too short, it’s useless information, as long as you memorize it, you’ll be fine.” Professor of Quantum Physics: "You mean there are two of you? With the same memory." He: "It can be said that, but from the moment I came here, our memory is different. I don't know what happened there, and I don't know what happened here, unless the memory is sent back." Me: "What you say, is that the soul is divided into two? This completely subverts religious beliefs..." He was a little disapproving: "Faith? Since it is so easily shaken and subverted, it is not called faith. I know that you are skeptical about the multiverse here, because that means there are many gods, many Buddhas, There are many Allahs, many Odins, so I deny it! Is that so? I don’t know what you think on your earth, but it’s not a problem here. Why can’t there be many souls? Why can’t there be many gods? If there is too much, it will be chaotic? If there is no God, there will be no faith? If there is no God, there will be no love? If there is no Buddha, there will be no enlightenment? Or an organization? True faith is unshakable, even if there is no god, it cannot affect your firmness. This is faith. True faith can accommodate all methods and forms. Only superstitious people call Calling each other all day long: you are wrong and I am right, you are evil and I am right. This is superstition, not faith." I think what he said makes sense, and I even started to envy that "his earth". Professor of Quantum Physics: "Well, let's put this topic aside for now. I want to know a technical question: How can you be sure that you can teleport to this universe? How do you locate it?" He: "Have you ever felt this way: when you see a certain scene, you suddenly feel familiar, and you can even predict what will happen in the next second?" Professor of Quantum Physics: "Yes, but it was a temporary illusion and error produced by the memory part of the brain." He: "Error? You can predict the next second when you make an error? Isn't it?" I looked at the professor of quantum physics, he looked confused: "Well... this..." He: "Actually, it's not a memory error, but your brainwaves instantly communicated with those of other universes. And the connected universe happened to be a universe a little earlier than you, and you got the memory information of another self. That is Shared. That kind of thing is rare because you can’t keep in touch with another self for a long time. The principle should be clear to you. In fact, it is another weak electrical signal from your brain memory that is transmitted to you through quantum foam. Although there is only one moment." My friend and I were a little confused.Especially me, a little trance, I think we are the ones who are mentally ill.Because all the doubts were easily resolved with him. Professor of Quantum Physics: "Um...you mentioned the earlier universe, right? Our view is that the universe is constantly dividing, not that there are infinitely many..." He: "You... well... don't you think this statement is too subjective and contradictory? Split? What is the standard for split? Is it your choice? Then other people's choices don't exist? Then the ancient people's choice is Does it not exist? The choice of your descendants will not exist in the future? All the split points in the past, present and future are constantly splitting? Disappear after splitting? No more? Only the splitting point after you choose still exists? This kind of problem ...such a simple logical question...I'm still a humanities student and I know..." The professor of quantum physics is a little embarrassed: "Because our earth is uncertain about the multiverse." He: "Okay, I'm a little anxious, sorry. I really want to know, logically and technically, what I said... Let's put it this way, am I mentally ill?" Me: "To be honest, if you are, then you are the scariest psychopath I have ever seen. What you said is basically feasible, but it cannot be ruled out that you got this knowledge by accident. However, I I want to arrange for you to try hypnosis, that should be of great help to you and us." He nodded slowly: "Maybe... maybe... It would be great if the hypnosis could find the return signal in my memory. Is that possible?" Me: "That's what I mean. If what you said is true, it is indeed possible!" He looked at me expectantly: "Then I can finally go back."
