What exactly is the definition of time?

Time is a scale, which is a scalar in the physical definition, by which the sequence of events can be determined in a past-present-future sequence (point in time), as well as the duration of events and the length of time between events (time periods). Time is the fourth dimension in addition to the three dimensions of space. Time is a concept in the human mind, used to describe the degree of change of things, it should not be confused with the dimension of space, the four-dimensional space is still space, and it has nothing to do with time.

The concept of time is the result of the linear logic of our subjective concepts, a subjective conceptual category rather than an essence. It can't simply be said to be wrong and right, existence or not, it is a relative existence. Because in a certain similar motion, it has a relatively balanced existence, and with the continuation of the movement of material existence, because it is a circle-like trajectory, our subjective concept, which is a straight-line forward logical habit, will regard this circle-like trajectory as a regression, so our concept of time is a relative self-existence, relative to the existence of essence.

If a concept is established, it can also be said that this concept does not exist, and it can only be said that it is a relatively existing concept of time, which belongs to the establishment of a subjective concept of human beings.

No matter how the natural sciences divide the space of human existence, for example, today's natural science research has extended the traditional definition of the three-dimensional space of nature to the five-dimensional and even six-dimensional space, including time. I'm not in the natural sciences. But I personally understand; First of all, it is necessary to make it clear that time physically represents a measure and number, and the number and the measure themselves are highly unified.

The definition of time, then, should be that in the space of time, all the processes of evolution of nature, including human beings, are recorded and frozen. That is, the process from quantitative change to qualitative change.

and causation. If you elaborate on the definition of time from a literary point of view, then I would think that time is defined by history.

The existence of all things is in the unity of opposites, so it is relative. In other words, there is no other thing, there is no other thing, and the same is true of time. Time is a category of human subjective concepts, or more precisely, a physical concept.

If the essence is to be pursued, it is a matter of philosophy. It would be meaningless to understand the concept of "time" in terms of physics, because it is a concept that has been defined by a subjective concept, and to review it with a subjective concept is not a thinking, it can only be learning.

Time and space is a kind of "invented concept" of human beings, just like natural numbers, natural numbers themselves are only a conceptual concept, meaningful is the correlation between natural numbers, think of binary and sexagesimal and decimal to understand, the key meaning lies in the correlation between concepts. Through the concept of invention, the correlation between concepts is established, and there is a correspondence with the perceived "information change". In the final analysis, people's understanding of the world lies in sensing information, and this is the only core.

The things that our concepts identify correspond to the existence of an essence, and in the essence, it does not compound with the definition of our subjective concepts. Because our concept of time originates from the manifestation of the difference in motion of matter, that is to say, with this differential performance, we can know the speed and slowness, the sequence, the beginning and the end of our subjective concept. However, in essence, there is no such thing as these phenomena that we subjectively identify, but rather follows a circle-like, infinitely cyclical generalization.

Because the concept of time that we have established is a judgment made in relation to the self, and it is the result of the linear logic habit of our subjective concepts. The motion of material existence, as far as the linear logic habit is concerned, is a quasi-equilibrium motion, but it is not absolute, because it has the principle of difference, which guarantees the continuation of the motion, so that the time established by our subjective concept does not reflect the existence of this equilibrium.

The future is the uncertain period after the present. It is part of the projected timeline that is expected to occur and may be considered limited and limited in scope, depending on the circumstances. While some may see the future as fixed and predetermined, most people see it as largely unknown (perhaps unknowable) and open to many different possibilities and permutations.

The study of the hypothetical possible, possible and desirable** and worldview is called futurology.

Basic concepts. Broadly speaking, when a point moves relative to a coordinate system, the line or line segment or curve formed by its motion is one of the times when the point is at rest relative to that coordinate system.

Each point corresponds to multiple times. Relative to a certain time, the faster the point at rest starts to move, the slower the time, when the speed is the same as the point moving in that time, the time stops, and the speed exceeds the point, which is equivalent to going back to the past.

Relative time. That is, real time, time expressed in real numbers. Refers to the time at which the point of non-extradimensional motion is formed.

Absolute time. That is, imaginary time, the time expressed by imaginary numbers. Refers to the time at which the point of extradimensional motion is formed.

Relationship with space.

Space makes things changeable, that is, because of the existence of space, things can change. Space is something without energy, that is, when things can change, the energy generated by the change has canceled each other out with the energy that hinders it. The description of a point changing in space is called the time when the described point is equivalent to the point (when the point moves to a certain position, the described point will have a unique corresponding position, which is called the position of the described point at this time).

The position of the described point can change with time, and it can be seen that time has a functional relationship with the position of the described point.

with parallel universes.

Broadly speaking, a parallel universe is a parallel space-time in which the universe has a difference in the direction of the universe in a higher dimension. Adjacent universes have a non-zero minimum difference in the extra dimension (coordinates), and the extra dimension is the imaginary time relative to the universe, which can be traversed by traveling through parallel universes.
