Time is relative, he can say that it can be long or short, but it can t be reversed.

This sentence of yours is obviously from Einstein's theory of relativity, the length and shortness of time are relative, but no matter whether time is long or short, there is no way to go back to the past, so time cannot be reversed.

Hello, it means that time cannot be reversed, it can only be said that it is very long, and it can also be shortened, but it just cannot be reversed.

It means that time can feel fast or slow, but time cannot be turned back and never go back.

The meaning of this sentence is that sometimes people feel that they are too blocky, and sometimes they feel that they are slow, but time is gone?

You can't turn back time, but when you do what you like, you will feel that time flies quickly, and when you do something you don't like, you will feel that time passes very slowly, so it is also said to be relative.

It means that a person's life is long and short. But time passes, and it won't come back. The present moment should be cherished.

Time is relative, and he can say long or short. The meaning of this sentence is that time can be said to be relatively long at certain times, for example, three autumns in one day. Sometimes it can be said that it is relatively short, and this is also related to people's mood.

The length of time is relative to him, although sometimes the relative length is different, and it cannot be shortened or repeated.

Time is relative, it can be said that it can be shortened, or it can be changed mindfully, it can control its own emotions and its own emotions.

Time is indeed relative, but time cannot be reversed, you can only go forward, you can't go back, so cherish the present.

In fact, time is just the transformation of space, and time is generated by the rotation and rotation of the earth around the sun, so time does not exist at all. It's just a unit that we humans have come up with for the convenience of calculation.

This means that the past is in the past and cannot be reversed.

It means that in your heart she has become so important, and in his heart you have become less important.

Time is relative, he can say that it can be long or shortened, but it cannot be reversed, which means that time is gone and never returned, and time is gone.

Time is relative, he can say that the field can be shortened, but it can't be reversed, I think time can only move forward.

It's relative, he can say long, he can say short, but he can't turn back means that time is good, sometimes you may think it's long, sometimes it feels short, but he can never go back.

It's really relative, he can be said to be sincere, it can be said to be short, but it can't be reversed, which means that it mainly depends on yourself.

In a broad sense, time is the change of the four seasons according to the rotation of the earth, and the length of each quarter is different, and we feel that the time will also change in length; In a narrow sense, 'time is a sponge, squeezing it is still there', the main meaning is that time is in our own hands, we need to make good use of it, do meaningful things.

Different people use their time differently.

It can be borrowed from the following: the plan of the year lies in the spring, and the plan of the day lies in the morning. Time is like a spring, which can be shortened or lengthened. Time is a river of gold, don't let it slip gently through your fingertips.

Time is tossed out by human beings.

I was a child, but the book says that only time will understand the greatness of love.

Time is a point that has passed.

Time is flowing water, if you don't cherish it, it will flow away quietly So, after listening to these, I believe that you will cherish it if you are smart!

To put it simply, the world is divided into material and conscious.

According to this classification, time is clearly material.

Time is something that people created to regularize their lives (for example, in ancient times, in order to regularize their lives, they established a week, 5 days of work, and 2 days of rest), and at the same time, they were also set by people according to the changes of the planets. (e.g. lunar, gregorical).

Time does not exist, it is people who "create" time, and the role of time is constraint.

Personally, I believe that time is an imaginary concept, a tool used to regulate the movement of matter. The special properties of the substance under certain conditions are due to the particularity of the substance under the same conditions.

Time rises in the east and sets in the west, alternating day and night, endlessly, and I don't know if there is an end when there is a beginning.

Albert Einstein believed that time is an illusion. Time and space should be able to travel through.

If the universe is a book, then time is the page number of the book, you can use the power of science to turn it to any page you like, but most people will choose to turn it in page order, so it becomes "life", what is time? I don't know, but we should cherish it!!

Noble is the epitaph of the noble, meanness is the pass of the mean.

A one-dimensional space that exists in this three-dimensional universe.

Time is an ordered law of the Earth, the Moon, the Sun, and the Universe

Time is an artificial decomposition of time and space! It's a conceptual number! It is the most unretained and irretrievable thing in your life!

Time is a physical quantity that can be measured, and the commonly used units are years, months, days, hours, minutes, seconds, etc. We use time every day, but we don't know what it is, time is very mysterious.

What should I do if someone asks me to take the time to show him? Show him a watch? No, this is a watch, not time; Tear up a calendar and show him?

No, it's a piece of paper, not time; Standing in front of him for an hour, okay? No, it's a penalty station, it's not time, all kinds of methods are wrong, I can't think of any way. Time is invisible because it cannot be shown to others.

What cannot be measured, science does not study, since time is invisible, how can scientists measure it? Originally, science represented time by measuring the movement of objects, for example, measuring the change of the earth's revolution around the sun as the time of a year; The change of the Earth's rotation in one circle as the time of the day; The single pendulum oscillates once as a time of one second; The vibration of quartz crystals and the rotation of electrons in atomic orbits as shorter times, etc., without exception, all replace time with the movement of the object.

Is the movement of an object time? If the answer is "yes", science is right; If the answer is "no", then the whole science is wrong. Therefore, we must face this issue with a serious heart.

Now let's try to solve this problem together. Suppose that all objects are stationary, and that the earth does not rotate or rotate; Single pendulum does not vibrate; Quartz crystals also do not vibrate; Electrons do not rotate in atomic orbitals; The plane does not fly; The car does not run; The heart doesn't beat and so on, can scientists still measure time? Of course not.

So is there still time? There should be no time. Everything is still and everything remains as it is, and all life has no birth, no old age, no sickness, no death, and of course no time, which is self-evident and does not need to be proven.

So the answer is: time is the movement of objects.

Diamond Sutra cloud: "The past mind is unattainable, the present mind is unattainable, and the future mind is unattainable", the three kinds of mind are unattainable, which means that the mind has not changed, so the past, present, and future are gone, and time is gone. If "the mind can be obtained in the past, the present mind can be obtained, and the future mind can be obtained", then there are three kinds of changes in the mind, so that the past, present, and future can be obtained, and there will be time.

This passage of the Diamond Sutra explains that the existence or absence of time depends on the movement and stillness of the mind, which is consistent with the scientific viewpoint, but science focuses on objects, and the Diamond Sutra focuses on the mind.

Time is a measure of the process of motion, specifically, the measurement of the process of motion that can be carried out by counting the period of motion.

Time has the following characteristics:

1. The specific units of time correspond to the period of a special movement. For example, the year, month, and day correspond to the period of the Earth's rotation around the Sun, the period of the Moon's rotation around the Earth, and the period of the Earth's rotation, respectively. The number of years, months, and days is counted for the corresponding periods of movement.

2. Since the counting of the exercise cycle is carried out in the order from small to large, what has been counted is the past, what is being counted is the present, and what has not been counted is the future. Thus, time is one-way and irreversible in the past, present, and future.

3. Since the retrospection or counting of cycles moving in both the past and present directions is continuous and infinite, time is also continuous and infinite. In other words, time has neither a beginning nor an end.

4. The method of measuring time is as follows:

The motion period of a particular object is selected as the reference of time, and the process of other motions is measured by counting this continuous motion cycle. That is, a special periodic motion process is used to measure other motion processes. This particular periodic motion can be considered as a temporal reference.

5. Time is not absolute but relative. This is because the special periodic motion chosen as the temporal reference is affected by other factors, and the movement period is not absolutely constant between them. For example, precise measurements indicate:

The cycles of years, months, and days are constantly changing, sometimes faster, sometimes slower, and the general trend is getting longer. The variation between them is also disproportionate.

In particular, each specific object has a certain lifespan, no matter how long it lives. If the object that is a reference of some kind of time disappears. Then this specific periodic movement does not exist at all.

We had to choose a new time benchmark. Therefore, there is no such thing as an absolutely immutable motion, there is no such thing as an absolutely precise and eternal clock, and there is no such thing as Newton's absolute time.

6. Space is a measure of the size and orientation of a substance, the measurement method is to use a ruler, time is the measurement of the movement process, and the measurement method is to use a clock. Any clock consists of a periodic motion and a counting mechanism for that period. Therefore, it must be emphasized once again that time and space have no relationship.

7. Space and time are both a measure, and the scope of this measure is limited in any historical period, but this does not affect the infinity of space, large and small, nor does it affect the infinity of time in the past and in the future. At the same time, the argument that space-time is bent is incomprehensible and absurd.

Time is money for businessmen, life for patients, eternity for lovers, and play for children.

Time is an abstract concept that can only be understood, not spoken.

Time is a human concept. It is one dimension in the space of all things. Your problem is a bit like a chicken-and-egg, egg-and-egg problem. Hehe.

Personal opinion:

1. The speed at which information is conveyed.

2, yes 3, inconclusive (can be fast or slow).

4. Yes. 5. Human life is nothing to time, but time is crucial to human life6、......

Time is the movement of light.

Fourth-dimensional cycles.

The unknown can be turned back in time.

Nothing is not.
