The philosophical definition of time
[Edit this paragraph]
The nature of time Philosophical definition: Time is a component of specific things, the existence and manifestation of movement, a cognitive object that people decompose and abstract from specific things, and the opposition between absolute abstract things and relatively abstract things, meta-ontology and meta-entity. Unity is an ordinary individual member that exists in the world collective and cannot be felt but can be known.
Time is a component of specific things and a general requirement of specific things. The specific things that can be seen by human eyes and touched by hands are all specific things in a certain period of time, and they all have specific provisions of time. Specific things without time provisions do not exist at all.
A person has a life span, a tree has a life span, and the earth, sun and galaxy known to mankind are all specific things that exist within a certain period of time. After a certain period of time, people are no longer the same specific person, trees are no longer the same specific tree, and the earth, sun and galaxy are no longer the same specific earth, sun and galaxy.
Time is the existence and manifestation of movement.
Movement has two specific forms of existence and expression: behavior and existence. Behavior is relatively significant movement, existence is relatively static movement.
All behaviors, phenomena and things have specific time provisions for their occurrence, development and end. Time is the manifestation of the occurrence, development and end of behaviors, phenomena and things.
Behaviors, phenomena and things can only happen within a certain period of time and can be shown to people in a relatively short period of time. At a fixed point in time, even if it is shot with a bow The arrow is also fixed. Only within a period of time, the arrow will be displaced. When moving from one place to another, the movement of the arrow can be expressed.
Different from the behaviors, phenomena and things of specific things, the existence of objects and the relative static movement of objects can only be shown to people over a relatively long period of time. The natural oxidation of metals, the natural growth of plants, and the normal development of animals are all relatively static movements. They are all the existence and manifestations of specific things. A relatively long period of time is the existence and manifestation of oxidation, growth, and development.
Time is a cognitive object that people decompose and abstract from specific things.
Motion is a component of specific things, the existence and expression of specific things, and an object of understanding that people decompose and abstract from specific things. Time is a component of movement, a manifestation of behavior and existence, and a cognitive object that people decompose and abstract from behavior and existence. Therefore, it can be said very accurately that time is a cognitive object that people decompose and abstract specific things many times, and decompose and abstract from specific things.
Time is a unity of opposites composed of absolute abstract things and relatively abstract things, meta-ontology and meta-entity.
Absolute abstract things or meta-ontology are the general regulations, laws, properties and essences that every concrete thing and every relatively abstract thing have. It is what people learn from every concrete thing and relatively concrete things. Cognitive objects decomposed and abstracted.
Relatively abstract things or meta-entities are the special regulations, laws, properties and essences of individual concrete things or individual types of concrete things. They are the decomposition and analysis of different individuals and different types of concrete things by people. An abstract object of knowledge.
Everything can be divided into two, and time is no exception. Time is a unity of opposites composed of specific time and general time.
What is the specific time? Specific time is a time with a specific quantity, a time period with a specified length, the specific existence and expression of general time, and a relatively abstract thing or meta-entity that exists in specific things.
What is general time? General time is a time with no specific quantity. It is a time period with no beginning and no end and infinite length. It is the essence and content of specific time. It is an absolute abstract thing or meta-ontology that exists among concrete things and relatively abstract things.
Time is a unity composed of specific time and general time. Specific time is a relatively abstract thing or meta-entity that exists in specific things, and general time is an absolute abstract thing or meta-entity that exists in specific things. Meta-ontology, so time is also a unity composed of relatively abstract things and absolute abstract things, meta-entity and meta-ontology.
Time is an ordinary individual family member that exists in the world collective and cannot be felt but can be known.
The world is a unity composed of individual concrete things. Individual concrete things are ordinary individual family members that exist in the collective world and can be felt by human sense organs.
Concrete things are cognitive objects that contain many regulations, are the sum of multiple regulations, and are the unity of diversity. By comparing different individual concrete things, people can discover the particularity and universality of each concrete thing, and then decompose and abstract the particularity and universality of specific things from individual concrete things and combine them By naming them, various abstract things that cannot be felt but can be known are formed and produced.
Abstract things are the components of concrete things. They are the various regulations, properties and essences of concrete things. They are the decomposition of concrete things formed and produced by the layer-by-layer decomposition and level-by-level abstraction of human thinking. They are ordinary individual family members who exist in a large collective of specific things.
Time is an abstract thing expressed by common nouns. Like other abstract things expressed by common nouns, time is an object of knowledge that cannot be felt by human sensory organs. Human eyes cannot see abstract people, mountains, and fruits, and human hands cannot touch abstract objects, water without temperature, and stones without hardness. Time, people, stones, fruits, tools, and water are all abstract things that cannot be felt but can be known. They are all individual family members with equal status in the collective of concrete things.
The world is a unity composed of concrete things, and individual concrete things are ordinary individual members of the world collective. Abstract things are components of concrete things and are ordinary individual members of the collective of concrete things. Therefore, every concrete thing and every abstract thing is a component of the world, and the world exists with every concrete thing and every abstract thing. Among them, every concrete thing and every abstract thing is an ordinary individual member with its own regulations in the world collective.
Time is a description of the speed of relative motion between objects
The physical quantity that measures the length of the interval between two moments is called "time". It represents the continuity and sequence of the material movement process. The period of any periodic movement can be used as a time standard. For example, the water leakage in ancient China and the twelve earthly branches (Zi, Chou, Yin, Mao...) all use periodic timing methods. Time is a fundamental physical quantity in physics. A period of time is represented by a line segment on the time axis. In order to describe time with specific numbers, a certain moment must be selected as the starting point of timing, which is artificial. The starting point of timing is not necessarily the moment when the object starts moving. In physics, the time the sun passes through the meridian of the observer twice in a row is called a solar day, that is, a day and night. Because there are slight differences in solar days, the average of all solar days in a year is used as the standard of time, which is called an average solar day, or 1 day for short. A day is divided into 24 hours, an hour is divided into 60 minutes, and a minute is divided into 60 seconds. Therefore, one 86,400th of a day is divided into 1 second as the time standard. But the seconds specified in this way are imprecise. In 1967, at the 13th International Conference on Weights and Measures, it was stipulated that 9192631770 times the radiation period between the two hyperfine structure energy levels of the ground state cesium 133 atom was defined as one standard second. International regulations take the instant of 0:00:00 UT on January 1, 1958 as the starting point of atomic time. Time often corresponds to displacement or average velocity, for example: "displacement that occurred in five seconds" or "average velocity in the first two seconds."
Definition
[Edit this paragraph]
In fact, a more comprehensive definition of time can be understood like this:
Time is related to space The fourth dimension with the same dimensions. In the human universe model, "time" must be involved to describe the universe.
And we know that the basic logic of the universe model is:
If event B occurs in area A of the space-time coordinate system, then it must occur in area C of the space-time coordinate system Event D occurs.
Obviously, in such a model built with human logic, time is only one dimension used to describe the position of a certain vector. The same is true with our ordinary understanding. But why can humans move around at will in the other three spatial dimensions, but can only move forward in the time dimension?
This is nothing but a clash of human brains.
Human logic requires four dimensions to explain the universe, but the way humans obtain information can only determine three dimensions. (The human eye cannot see through time) In such a conflict, on the one hand, humans are interpreting four dimensions, on the other hand, humans can only determine three dimensions. In this way, humans can only feel the fourth dimension (time) The passage of time and the changes of the other three dimensions in the fourth dimension. This is how we feel about time now.
However, in fact, the time we "see" in our eyes and thinking is not certain. That's because the world is relative, and time is no exception. Ever since our great human scientist Einstein discovered the laws that transcend time, humans have begun to explore time. I believe everyone has heard of the "speed of light theory" - when the speed of human movement is infinitely close to the speed of light, the surrounding time will slow down. There is even a situation where "only one day in the mountains lasts a thousand years in the world". But even so, human beings still face another time problem-relative time. As in the above example, "a thousand years have passed in this world" is just time for us ordinary people. And the person who is moving at the speed of light is still faced with "only one day in the mountains" relative to his own time. The so-called "only one day in the mountains, thousands of years in the world" is only relative to those of us who move at normal speeds. That’s all. Time that transcends one's own essence will still have another essential time relative to itself to constrain itself. Therefore, human beings' exploration of time will never end. Because relative time will always exist in this world, time will always exist. Beyond the essential time, we will enter a new time rule.
Time theory, essence, factors
[Edit this paragraph]
What is time? People have many ideas about this issue. In any case, we have to use Scientific method to explain time.
Definition;
1. The principle of equality of space and time areas; the length in the motion system 1 or the observation system 1' is the inherent length, and the time is the inherent time. If length and time are multiplied, the two space-time coordinate systems are equal.
2. The principle of space-time deflection; if the motion system moves relative to the observation system, the relative speed at a certain moment is u or u' , the motion system and the observation system deflect along the relative motion, the deflection angle θ is the space-time deflection angle, and the size of the space-time deflection angle is related to the relative speed, that is, sinθ=u/c. This is the time factor.
Time The essence of time
[Edit this paragraph]
Time is the process of inherent material displacement in the universe.
The essence of time refers to the process of material change and development, so it is material.
The length of time refers to the artificial process measurement, so it is conscious.
Interpretation
[Edit this paragraph]
① The attributes of material existence that can be measured by clocks. The occurrence, development, and termination of a certain process reflect both the continuity and the sequence of the process. The continuity of the process is represented by time intervals, and the sequence is represented by dates and times.
②The basic form of moving material existence. Time is the continuity, interval and sequence of material movement, and space is the extension and stretch of matter. The characteristic of time is one-dimensionality, that is, irreversibility, while the characteristic of space is three-dimensionality. Space-time is inseparable from the movement of matter. There is no space-time without matter and material movement, and there is no matter without space-time. Matter is eternal and absolute, and space-time, which is the basic form of material existence, is also eternal and absolute, but the specific manifestations and characteristics of space-time are diverse, changeable, and relative.
◎Note: Academically speaking, time is not one-dimensional, nor is it an irreversible passage. Time is two-dimensional, like the plane of complex numbers. Time has a real axis and an imaginary axis. Time is meaningful on the real axis, which is the real time, which is what we call time: past, present, and future. The point on the imaginary axis is just a form of time, a possible situation, which is meaningless in our view. Because the existence of virtual time cannot affect us at all.
But if one day we can time travel as Hawking said, we will pass through the virtual timeline. By then, virtual time will not be difficult for us to understand, and it will have an even greater impact on us.
More detailed explanation
[Edit this paragraph]
The time attribute of an object can only exist when and only when the object is connected with the external body. The time attribute between objects exists due to the synchronization between objects. Each object affects the temporal properties of the object associated with it. They synchronize it.
Just like a black hole, time is stagnant because it is separated from the outside world. Although there are foreign objects entering inside, they are synchronized with the black hole because they are all subject to the strong gravitational pull of the black hole. Therefore, the time properties of a black hole are only affected by itself.
What time is it now? ” or “How long is it until New Year?” "I'm afraid even primary school students think this is a simple question. But if you reverse the word order and ask again: "What is time? "I am afraid that most people will feel confused. This is indeed the case. "Time" is an important, common and used concept for us: "We must seize the time", "Wasting time is equal to wasting life", "Time is money"...
People regard time as an object that exists independently and flows evenly endlessly without relying on anything else; in middle school students' mathematics and physics textbooks, time is expressed as A straight line with a starting point, a unit, a direction, a beginning and an end, this is Newton's "absolute time" that is consistent with people's common sense, and it was also the scientific concept of time that was generally accepted until the beginning of this century.
The truth is relative. Yes, it always develops with the progress of science. After mankind entered the twentieth century, new results and discoveries in physics and astronomy challenged the basic concept of "absolute time" in the narrow sense of Albert Einstein. The theory of relativity points out that time cannot exist independently of the observer of the universe and its events. Time is an aspect of the connection between the universe and its observers. Different observers who are moving at a relatively constant speed will generally measure different events for the same event. Time. For example, a clock that moves at a constant speed relative to the observer always runs slower than a clock that is stationary relative to the observer. The greater the speed of the clock relative to the observer, the closer it is to the speed of light. In addition, Albert. A direct corollary of Einstein's general theory of relativity is that due to the gravitational field, clocks at different altitudes on the earth's surface run at different speeds. The higher the altitude, the faster the clock speed. The difference is about 1.09×10-16 seconds/meter (altitude ), that is, the clock speeds up by one quadrillionth of a second for every 100 meters of elevation. These predictions made by Albert Einstein's theory of relativity have been verified experimentally. In addition, if it is admitted that according to Albert Ein. Stein's theory of relativity and the "Big Bang" universe model proposed by the major astronomical discoveries of this century (the red shift of the spectral lines of extragalactic galaxies, microwave background radiation, and approximate helium abundance in different galaxies), then we must accept that our universe must have a "beginning" ( At least 10 billion years ago), and there may be an end (at least tens of billions of years later), what a shocking conclusion!
Fortunately, it was developed by Albert Einstein’s general theory of relativity and The latest research results of modern cosmology derived from quantum mechanics are: our observed universe (with a range of about 15 billion light-years) is finite and unbounded, that is, it is limited but has no boundaries (or edges) on the space-time scale. There is no beginning or end, no birth and no destruction! Of course, this is just a relatively new model of the universe, and the scientific predictions made from it need to be verified by actual observations.
In short, "What is time?" "The problem is essentially to explore the nature of time. This is only a topic that a very small number of scientists and philosophers are passionate about, and it is far from a satisfactory result. It seems that it still needs to be explored for a long time. Fortunately, the actual nature of time For application, conventional understanding is enough. In certain fields, it is sometimes necessary to add relativistic corrections to time

Modern Chinese Dictionary Explanation
[Edit this paragraph]
Time is an objective form of material existence, consisting of the past, present and future. system. It is the manifestation of the continuity of material movement and change. It is an important factor in the connection between the object and the external body.
So what is time? People have been thinking about it since ancient times... What is "time"? At the end of the day, time ran out and he couldn't think about it anymore. He still couldn't figure out what "time" was? So what is "time"? What is "time"? This is something that all religions and cultures have to think about, but science explores the meaning of time from its relative relationship with space, and the definition it found is "four-dimensional space." What is it actually? Time is invisible, but space can be measured from the range of visible matter. The measurement of time and the measurement of space are two completely different things. So when you are measuring in space, you can use a ruler to measure and measure, and just follow it and keep walking. This is the measurement of space. Time is not measured in a straight line. With a watch, it goes back and forth and is always there, but it keeps passing by. But you have the concept of "going around and starting again", and this concept of "going around and starting again" is something. , The West defines what time is based on conclusions drawn from natural phenomena.
When we see spring, summer, autumn, and winter, we return to spring, summer, autumn, and winter. Every time when the leaves fall, you say, "Autumn is here again!" One autumn, two autumns, and three autumns are just one day, because "one day is like three autumns", so you use "time" and " "Space", "Relativity", "Einstein", and "Chinese Literature" are all connected together. "One day is like three autumns." Every time the leaves fall, one spring, another fall, another autumn, another fall, and another autumn, you wonder where the time is turning. Is time turning or am I turning? How on earth does time revolve around me? Or am I wandering around in time, and in the end I am getting old.
What is it? Is "I" moving while "time" is still, and then I move in the middle of the static "container" of time until I finally enter the grave? Or is "I" still and "time" moving among me, and then pushing me to a point where I will never return? So the East uses the Heavenly Stems and Earthly Branches, and the Chinese use sixty years as a way to calculate time. The West also looks at history from a revolving perspective of time. In this way, no matter whether it is Greece, China, or India, the concept of time cannot escape from the closed system (closed system), and it is still spinning inside. In this way, science, culture, philosophy, history, time perspective, and cosmology are all tied into that close system
