It is difficult to talk about the existence of human communication, and even those truths do not make it any less difficult; Most of the existing theories of existence in the world, including religion, are inclusive in substance, and there are only differences in the level of understanding and perspective, so whether it is now, in the past or in the future, science, philosophy and even religion must tend to be unified on this issue; If the imbalance must be caused by the backwardness of development on the one hand, and not the cause of itself, you may understand better if you understand what I will say below; I can't measure whether my understanding of existence is beneficial to you, and if you have the opportunity to have your own understanding in the future, you will evaluate it personally, but I can at least be sure that I can say my own evaluation of it calmly, from the heart; If you feel that you don't agree, then you can completely share your understanding with me, of course, you don't need to force yourself, because no one knows except yourself, so let's get started: about the existence of man himself, no matter from what point of view, if it involves the following three points, it must be crooked; 1. No matter what kind of understanding it is--- it is impossible to cure physical pain with spiritual things; 2. Materialistic --- no matter what way it is, spiritual things will not satisfy your materialistic needs; 3. The qualitative change of the physical body--- no matter who he is, what he perceives, but as long as he exists in the flesh, he is not fundamentally different from you; In saying three spiritual aspects, it can be given: 1. Gratitude --- recognition that there is a higher way of communication than words, or that the transmission of information is rational; 2. Wisdom --- improvement of the spiritual level can improve the individual's ability to understand things; 3. Cundao --- comprehend a certain level of spiritual level to understand life and death, and understand the way of heaven; Regarding space-time or the universe, people have always had their own division criteria, which may not be very unified, but the understanding of using dimensions as a reference is basically the same at present, and different dimensions divide different concepts of space-time; Here we have to say more, space-time and the universe are actually similar in definition, but they are different in order, space-time is time and space, and the universe is space and time, in addition, both refer to the existence of reality composed of space and time, which is not in particular order, there is no logical problem of the chicken and the egg, and there is no such problem in reality, space and time are generated at the same time, and they coexist with each other, even if they return to zero and stagnation, they do not affect their existence, time is an order, and space is its carrier; More people can understand through their own reading and perception, after talking about the concept of space-time, we are looking at the dimension, the essence of the dimension refers to the number and composition of space-time, in a general sense, we call a point space-time, called zero-dimensional space-time, linear space is one-dimensional space-time, and the plane composed of one-dimensional space-time is two-dimensional space-time, and so on to launch three-dimensional three-dimensional space-time and four-dimensional space-time and space-time and finally eleven-dimensional space-time, there are different opinions on the order of magnitude of this space-time dimension, some think that it is ten-dimensional, nine-dimensional, 7-dimensional ...... But in fact, this judgment itself is problematic, and it is too one-sided to regard the increase in its dimension as an increase of magnitude; Usually people will think that a high-order of magnitude space-time should be greater than a low-order of magnitude space-time, which is too straightforward and one-sided interpretation, high-dimensional space is only a special case of low-dimensional space or solidification, and there is no high-dimensional superiority in people's consciousness, that is to say, there is no correspondence of that magnitude, this superiority comes from people's belief that high-dimensional space can be freely chosen in its structure, which is completely a misunderstanding, high-dimensional space does not have this kind of jump, Or to be more precise, the more high-dimensional space is, the less it has this kind of jump, and the jumpiness of space will decrease with the increase of its order of magnitude, rather than the improvement in people's concept, that is, a one-dimensional space cannot voluntarily jump to any point zero-dimensional space on it; On the contrary, a point zero-dimensional space can appear in any one-dimensional space, and the same two-dimensional space cannot be abstracted back to any one-dimensional linear space, but a one-dimensional linear space can appear in a two-dimensional space, and the same three-dimensional space to high-dimensional space does not have that kind of autonomous jumping, nor does there exist the kind of four-dimensional space to three-dimensional space and five-dimensional space to four-dimensional space crossing, etc., which are all artificial one-sided understanding; Based on this understanding, it is natural to produce the kind of division method that isolates it, so this division method itself is problematic, there is no independent dimension, only an orderly whole, one-dimensional space is evolved from zero-dimensional space, two-dimensional space is evolved from one-dimensional space, and three-dimensional space is evolved from two-dimensional space, so it is easy to understand that we make such an statement, but we must understand that there is no one-dimensional space that is independent of a zero-dimensional space, and there is no two-dimensional space that is independent of ...... one-dimensional space. Therefore, there is no control of the high-dimensional space over the low-dimensional space, and only the change of the low-dimensional space to the high-dimensional space is possible; A more figurative metaphor is like a person and the cells he consists of, there is no such thing as a person without cells, and there is no cell that stops acquiring, and we cannot say that the magnitude of a person as a whole is greater than the magnitude of an atom, if the atomization of a person is still an atom in the final analysis, not as a human being as a whole; It is easy to misunderstand here that we are talking about the magnitude of time and space or the magnitude of energy, not the evolutionary level of biology, which is the limited understanding of human beings based on their own center, and there is no evidence or reason to prove that the level of a two-dimensional creature is lower than that of a three-dimensional organism or that the ability and IQ of a two-dimensional creature are lower than that of a three-dimensional creature; Our understanding and division of the limited biological hierarchy is based on a one-sided understanding of ourselves and the limited time and space in which we live; These are two completely different concepts from what we call the magnitude of space-time;
