Before explaining the spatial and temporal structural system of the plane, we must first understand the concept of similarity.

The entire understanding and division of plane architecture is based on the measurement of similarity differences between different planes. However, in the actual use of plane development, our definition and measurement of similarity, an important physical quantity, is based on the viewpoint of sociology and history. We define the similarity of this plane by comparing the differences in the development history of a certain plane civilization with the development history of a standard plane civilization. Regarding the actual measurement of similarity, there is a huge index system, and students who are interested can refer to related books. Although some scientists believe that the similarity of a certain plane is related to the spatial and temporal structure of this plane and the spatial and temporal structure of a standard plane, there are still no relevant theories and discoveries that prove this point.

As we all know, the plane we are in is defined by the Space-Time Administration as A001GENESIS, that is, the origin plane. On this basis, a series of A planes with the absolute plane as the standard plane is formed. But this does not mean that the absolute plane is actually the standard plane of the A-series plane. Instead, the absolute plane is the first plane to travel across planes and develop planes among all the planes we have discovered. At the same time, the absolute plane civilization is the highest-level plane civilization among all discovered plane civilizations. The Space-Time Administration is also established by the absolute plane civilization.

During the process of plane development, we defined some other series of planes based on similarity as the standard, such as B, C, D and other series of planes. Among them, the standard planes of each series, such as B001, can be considered to be the first plane in this series of planes that can independently study plane technology, manufacture plane bases, and independently conduct cross-plane travel and plane development.

Next, we will explain the law of decreasing similarity (entropy) mentioned in the previous chapter. Suppose there are two planes A and B, A is the standard plane of B, B is the similar plane affiliated to A, and A and B are not affected by any other plane. Let us still take Napoleon as an example. The history of Napoleon in plane A is standard history, while Napoleon has an excellent successor in plane B, who successfully shaped France into a constitutional capitalist country, rather than a presidential republic in standard history.

From a sociological or historical perspective, this change has no problem and is in line with the laws of social development. At the same time, since this change is generated by the B plane itself and is not affected by any other plane, it does not produce energy transmission and transformation across planes. However, it is obvious that the similarity between the B plane and the A plane is reduced. During the actual plane operation, the plane itself will constantly produce such slight changes, resulting in a continuous decrease in similarity. That is, we believe that it conforms to the law of decreasing similarity (entropy).

Finally, it is an introduction to the N-D buffer zone. Research believes that the N-D buffer zone is closely related to the space-time structure of the plane universe and plays a crucial role in stabilizing the N-D buffer zone. The large-scale reduction of the N-D buffer zone will directly affect the stability of the N-D buffer zone's space-time structure and even lead to the plane collapse.
