Why is number 0 symbolized by a mysterious circle?

Thousands of years ago, 0 was used by people with different symbols. But only after the AD, does the number 0 have the round shape as it is today. Why does 0 have such a circle?

Like every other digit, zero is a thing, a phenomenon of nature and human society. During the development of the natural and social world, all things, phenomena have the opposite sides as scientists have pointed out. Zero itself is the opposite, manifesting as the number of revolutions of things and phenomena in the development of the natural and social world, measured in the rotation of the Earth.

If viewed from the perspective of the Catholic calendar of human society, then the "negative" integers (-) are of the pre-BC years, the "positive" integers (+) are of the AD years; while zero is independent , and is closely related to both negative and positive numbers. The number 0 is not only considered the "intersection" point between negative and positive numbers, it is the symbol indicating the "blank" of the numbers, but also the "separator" (dividing tile) between negative numbers and positive, when looking at each digit, it includes the fractional opposite numbers (+/-).

Thus, from the perspective of the turnaround time of the digits as well as all other things, phenomena, 0 is considered to be the separator, at the same time, as a symbol of the time when the Earth rotates. a circle around it at the time of (current) interchange in the Earth's process around the Sun; Negative numbers are considered the symbol of the time when the Earth rotates around it at a previous time (past); positive numbers are considered the symbol of the time the Earth rotates around it at a later time (future).

In other words, the circle 0 is the symbol of the round Earth , and the icon of an Earth's circle orbits it, just like any other figure. For example, number 1 is a symbol of 1 number 0 (1 rotation); number 2 is the symbol of 2 numbers 0 (2 turns); number 10 is the symbol of 1 number 0 (1 rotation), because 0 is just a repeat number after a cycle; number 101 is the symbol of 2 zeroes (2 turns); 110 is also a symbol of 2 zeroes (2 turns); .v.v .

From the perspective of human history, referring to the number 0 refers to the current history of the human being , or the "ancient" part of the human condition; positive numbers are considered future histories, or the "head" part of the human condition; and negative numbers are considered the past history, or the "body" part of the human condition. That means, zero is an extremely important position. Speaking of integers, it is impossible to lack zero, negative and positive numbers, as well as the living person cannot be missing the neck, the body and the head. That also means that, when some people in human society are lost, there are people living in the present who keep historical records of the past; and the historical documents of the future have not yet appeared, but there will be those who live in the present creation. In other words, the history of the past, present and future is coexisting in the universe by living people, just as the scientist Albert Einstein once pointed out.

From the perspective of political science and law, referring to zero, it refers to the institution of the country, ie the implementation of national laws. Accordingly, positive numbers are considered state (the first part of the human condition); negative numbers are considered social (the body of human condition); and 0 is considered a law (the ancient part of human condition). That shows that law enforcement in the country has an extremely important position and role. People live indispensable to the neck, just as the country exists cannot be without law enforcement. In other words, every country in human society must have a state, a law and a social community. State (individual) - group, and society (community) - many groups, are opposites in the country; while laws exist independently objectively, playing a role in regulating conflicts between the state and society. Proper law, perfection and strict law enforcement are an important basis for a stable, sustainable development of the nation in the era of globalization.
