The place where you are and the world you can recognize are generally described as three-dimensional space, we try to use mathematical methods to explore the higher dimensions, that is, the high-dimensional universe in the general sense, the following information comes from Du Niang, the most mysterious occult comes from the unknown, and the most unknown places in this world are precisely those theories that have not been verified with science and technology for the time being, and these are the occult foundations we need, of course, we don't really need to study those theories, Because unproven is possible and fallacious, and what we have to do is to provide those different perspectives and divergent thinking from an outsider's perspective, just like those open-minded science fiction writers did more than a hundred years ago, although with the specialization of our social knowledge, our brains seem more and more insignificant, but I think, at least I don't want to lose these good habits of our liberal arts students, like to think blindly, like to think about problems with perceptual thinking rather than rational thinking.

Today's goal is the four-dimensional space, as a guy who firmly believes in the existence of a master-level true god, his understanding of the high-dimensional world must be more in-depth than others, so that a master can be more like an omnipotent master, so as not to let his master become those piglets hanging in the sky and being slaughtered... Four-dimensional space is different from three-dimensional space, which refers to standard Euclidean space, which can be extended to n-dimensional; Four-dimensional space-time refers to a misunderstanding of Minkowski's concept of space. As three-dimensional objects, human beings can understand four-dimensional space-time (three spatial dimensions and one temporal dimension), but they cannot recognize and exist in four-dimensional space, because human beings belong to the third spatial dimension. Time is usually the fourth dimension, that is, the time dimension under the fourth dimension of space-time. The fourth dimension of four-dimensional space refers to the dimension of space with the same properties as x, y, and z. In physics, the parameter that must change to describe a changing event is called dimension. A few parameters are just a few dimensions. For example, the position of a "door" is described only by angles, so it is one-dimensional rather than two-dimensional. To put it simply: zero-dimension is a point, with no length, width, or height. One dimension is a line composed of countless points, only the length, not the width or height of it. A two-dimensional is a surface made up of countless lines, with length, width, and no height. A three-dimensional is a body composed of countless faces, including length, width, and height. Because the human eye can only see two dimensions, and two-dimensional creatures only have one line to see each other. The human eye sees two two-dimensional projections, which are processed by the brain to form a holistic vision. To put it simply: n-dimension is the space formed by two or more n-1-dimensional objects perpendicular. Because, humans can only understand 3 dimensions, the later dimensions can be constructed by mathematical theories, but it is difficult to understand carefully. In quantum mechanics, string theory, which is still being established, holds that the world is 11 dimensions. First of all, the wrong way to say that "four-dimensional space is defined as three-dimensional space + time axis", and "three-dimensional space + time dimension" is another way of saying it. The former is not a four-dimensional space-time, and the four-dimensional space-time itself is a pseudo-concept. It's very simple "time is just the concept of the movement of particles and the expansion of the universe, why can it become the fourth dimension" (here the personal understanding is that time is generated because of motion, just like the pots and pans around us, so although time is invisible and intangible, but time is just time, just a very common subsidiary concept of the three-dimensional universe, and if you think about it deeply, it means that maybe a conclusion we have reached before must be overturned, Since time in the same dimension is only a very ordinary attribute of this dimension, then I have a very interesting inference here, it is about the gods, if these great beings really exist, and time is just a very ordinary concept, then they should not have the possibility of being killed, because they are everywhere, they exist in any corner of the long river of time, but in this case, I don't know how they broke through the barrier of time, if it is like the bronze dragon in the mountain pass, Then they should be in the middle of our time and space and other time and space, only in this way will they not be interfered with by time, if there is another situation, that is, they themselves are like what our Taoists say jump out of the Three Realms and are not in the Five Elements, then it is powerful, to put it simply, it is a leaf in the ten thousand flowers and does not touch the body, then they are everywhere, maybe behind your back, the only difference between these two situations is that they are, where are the regions where those great beings are located, If they are around us, but we can't see them, that is, the so-called gods, then the water in our world can be deep, I don't know how many gods have been handed down from ancient times to the present, you must know that if you are not bound by time, the gods will not fall naturally, and because they exist in any corner of the timeline, so theoretically the gods will not fall, and there is another situation, that is, the gods are looking down on us in the cracks of our world, That means that our universe doesn't know that there is a civilization like our human race, and the gods will not be bored enough to just stare at one channel to watch, even if they are so boring, after countless years, I don't believe that the human world has not been reshaped, after countless reincarnations, our evolutionary history, they have long been tired of watching, otherwise, there would not be the current situation). In addition, there is a difference between the concepts of space-time and four-dimensional space, and the statement that four-dimensional space is defined as three-dimensional space + timeline is a misunderstanding of the concept of Minkowski space, and why is this misunderstanding so widespread? Quite simply, countless science fiction novels and even popular science books have deliberately applied such a thing, causing a wide range of readers. I don't know if the above official scientific view has clearly denied the possibility of the time dimension as a high-dimensional universe, simply put, for science students, in their minds, the four-dimensional universe should be a world with four constant structures, not a world after the evolution of an infinitely extended timeline (or the past, present and future of this world are only components of this three-dimensional world, and cannot become a high-dimensional universe, because for our three-dimensional world, Missing a node to build a four-dimensional world? We can't understand the four dimensions, so we'll always be in the three-dimensional world. I don't know if that's what I mean, I'm a liberal arts student, and this is the above point of view that I use my own thinking to explain), a useful result about zero vectors: "If two zero vectors are orthogonal (i.e., zero inner product), then they must be proportional (constant). The above zero-base temporal orientation selection, as well as the concept of time-like vectors, make many people mistakenly think that "space and time form another space", when in fact it only describes the synergy of time and space. This is where the previous statement comes from. In fact, the time dimension is an alternative statement, not that the fourth dimension is time, and the previous statement is not the same thing, the fourth dimension has continuity in the mainstream statement, the famous mathematical model Klein bottle, the fourth dimension passes through the three-dimensional essence polyhedron, but the essence of the four-dimensional space is still space. And why this dimension is defined as the time dimension is because there is a certain school of thought that the extended "time" has a spatial nature, so an alternative way of saying it appears, you can actually call it anything, it is a nomenclature that arises under a unified and definite definition concept according to the autonomous concepts of different schools. Some students are a little entangled in the term "space-time", and there is another reason for the statement that there is no four-dimensional space-time, that is, the concept of space-time in modern physics is originally four-dimensional, so there will be no five-dimensional space-time, and there is no space-time that is specifically stated as four-dimensional. A certain school of modern physics believes that time and space are mutable and mutable, and their variables exist in each other, and the wide area they correspond to under certain conditions is called space-time (the earliest people did equate space-time with space plus time, and now they are more avoiding this original definition), space-time may be distorted or concave by the influence of matter and energy, and its smallest units are Planck time and Planck length. This is where the concept comes from, but many people use space-time and four-dimensional space together, and the two are related, but they can't be mixed. Broadly speaking: dimension is the number of abstract concepts that are "connected" to things, and "connected" abstract concepts refer to abstract concepts that are formed by the connection of two abstract concepts, such as area. So the fourth dimension is composed of four related abstract concepts, the fourth abstract concept is real time, and the fourth connection value is velocity. High-dimensional space-time and high-dimensional space are different. For example, in 3D space there is only one dimension of time, but it is a pseudodimension, i.e., its units are different from the other three dimensions. The fourth dimension of four-dimensional space still has the same properties as the dimension of three-dimensional space, and time is still a pseudo-dimension. Therefore, space-time and space should not be confused. (At this point, it can be summed up in a nutshell, that is, the space-time cannot be a high-dimensional universe, because time and space are a constant of our three-dimensional universe?) The change of time is only the change of time, and will not let this three-dimensional space evolve into a four-dimensional space based on the evolution of time, because time itself is a pseudo-dimension, if one day our world becomes the legendary high-dimensional world, there is only one explanation, that is, we recognize and analyze a basic quantity that can be the same as the length, width and height that we have always recognized before, and can turn the three-dimensional world in our cognition into a four-dimensional world. It's all just an unknown... Well, forgive my ignorance, I'm not very interested in these lofty theories of four-dimensional thinking. Because what we're supposed to do is to break down these assumptions and open our minds, and here's my personal nonsense time. ）

Scientific cognition can only let us know the known science, in the exploration of unknown fields, science students are accustomed to using data and calculus, we are not into the stream of liberal arts students can only rely on their own brains and deduction, philosophy is a good knowledge, but don't take your brain to learn him, really, in my personal deduction, the high-dimensional universe exists, but the high-dimensional interference in the low-dimensional world is also very weak, just like those scientists say two-dimensional world, The world that we are writing and painting now is a typical two-dimensional world, but you have to know that we can create a story, we can arrange the climax of the development of the whole story, but in order to ensure the coherence of the whole story, we can't make scalpel-like changes to one of the points, just like I did before, and there is only one result of the modification, that is, the ending of the whole story deviates from the direction we originally expected at the beginning, sliding into an uncontrollable abyss, that is to say, it is a new story that is completely different from the previous story, even if their ontology is the same. Okay, so let's replace the word story in the previous passage with the word "world". We can create a world, we can arrange the climax of the development of the history of the whole world, but in order to ensure the coherence of the whole world, we cannot make scalpel-like modifications to one of the points, as I did before, and there is only one result of the modification, that is, the ending of the whole world deviates from the direction we originally expected in our hearts at the beginning, and slides into an uncontrollable abyss, that is to say, it is a new story that is completely different from the previous world, even if their ontology is the same. How, it can almost be said that it is perfectly seamless, in my understanding, the high-dimensional world can also be pre-planned for the future of our world, as if we can write, but they can only write a whole story, and then they can't modify it... But because they lose the ability to interfere in our world after writing the predetermined ending, this is our greatest freedom, the so-called destiny that is changeable and irreversible. If there really is such a connection, there is no doubt that our three-dimensional universe is nothing more than passers-by A and B or something else in their screens, and we may even be the protagonists. The protagonist of the era? Sam, that maybe. I can't be one of them anyway. (To be continued.) )
