People and people know the world differently, and the mental time is also different.
Time is artificially prescribed, but it can definitely bind people and allow people to move within time. As long as the concept of time is determined, no one can escape the constraints of time, people can work together according to a unified time, can listen to the command at a unified pace, and can do many great things that cannot be done by a single person. However, people know the concept of time differently, and even the time that a person knows in certain circumstances is not the same. Perhaps, time does not exist at all, and what exists is only the concept of time that people recognize, or the subjective time and psychological time of human beings, rather than objective time.
Time may not exist, but only the concept of time, which is also called mental time. Some people cherish time and always think that there is not enough time. I am busy all day long, making a lot of money, but I just don't have time to relax. Time has become a river in their consciousness that flows forward forever, and it is a river that flows rapidly, and it cannot be stopped for a moment. People can only hurry, and they can't let time wait. Some people don't take time seriously, they are not so busy, but very leisurely, drinking tea, chatting, playing mahjong when they have nothing to do, and always think that time flies slowly, and it is difficult to stay up all day long. You have to kill time to feel better. In front of them, time is something that can only be used to kill, but there is no need to catch up. Because time will always pass, it will not favor those who are busy and busy, nor will it favor those who are leisurely, it seems to be very fair and objective. However, time is not the same in everyone's mind.
As Albert Einstein said, "If you sit with a beautiful girl for an hour, you feel like it's only been a minute." If you sit alone in your room for a minute, it will feel like hours. This is the theory of relativity. "Time is relative, not absolute. Time does not change, but change creates time. Newton and previous scientists believed that time and space are absolute, that a day is a day, that time passes, and that space does not change. For Einstein, time and space became relative concepts. Time is fast and slow, not constant. The time that a thing experiences is not fixed, but related to its state of motion, that is, our time and space are changeable, relative, and interactive. When the speed of light is exceeded, time slows down, and even as the speed increases, it is possible to turn back time. However, until now, mankind has not developed a flying machine that exceeds the speed of light, and it is impossible to travel back in time.
Human perception of time is subjective and even personal, unlike the perception of others. People with a slow temperament think that time flies quickly, while people who are impatient think that time flies slowly. Especially when waiting for someone, people with a slow temperament can wait, but those with an impatient temperament can't wait. The time they know is different, although they all know the time when the clock goes, they clearly feel that the time is not so fair and just. In other words, they will observe the time of the clock, but they will clearly feel their own psychological time, not the so-called objective time. After people have been domesticated by social rules, most of them are more utilitarian and secular, and they will revolve around their own interests, and the more this is the case, the more one-sided their understanding of the world becomes, not to mention their understanding of time.
In fact, people's perception of time is different, which will lead to different results. Some people will work against time, some people will squander their time, some people will go with the flow, some people will kill time, and some people will not feel sensitive to time, and they will not even feel that they have time, they will only live every day, or even live for several years, and they will not feel it. A lot of people are trained in real life to be numb and don't feel anything new. And time seems to play a joke on people, making people feel that time flies slowly when they are young, and when they are middle-aged and old, it feels like time flies by and does not stop for a moment. Most people seize the time to struggle when they are young, and only a few people can grow old and fight against time. Time seems to be water in a sponge, and as long as you squeeze it, you can always squeeze it out. Of course, many people don't have to squeeze in time, they just need to work and live step by step. But people don't think the same way, and so do they have a different understanding of time.
There is a saying that "time does not spare people, and I have not spared years." "Time seems to be something that can be grasped, and as long as you strive for it, you can be efficient. It's the same minute, you can sleep, you can also read;You can fall in love or you can work;You can eat, you can fight;You can go shopping, or you can brush short**. The things you do are different, and the sense of time is different. People all over the world do different things and have different feelings about time. Even if all people are doing the same job, they will have different perceptions, different perceptions of time, and these understandings are not interchangeable, they cannot replace each other, and they cannot convince each other.
A person's perception of time is also different in different environments, when he is happy, he feels that time flies quickly, and when he is sad, he feels that time passes slowlyWhen you eat something good, you feel that time flies, and when you are hungry, you feel that time flies slowly;When you are in love, you feel that time flies, and when you are in love, you feel that time flies slowly;When I travel, I feel good and feel that time flies, and when I am alone at home, I feel that time flies slowly. There was once a famous cave experiment, in which the woman who was tested entered a specially designed cave with a constant temperature of twenty or thirty square meters, without a clock or other thing to calculate time, and could not come into contact with society. There is plenty of delicious food, water, books, musical instruments, etc., and a computer in the cave, but there is no time and no Internet access. At first, the woman felt fulfilled, but over time, food, water, and books could no longer meet her needs, and after she slowly lost time, her biological clock began to become confused. Her sleep has changed, she can sleep 20 hours a day, and she can maintain it for 20 hours when she is awake, which is equivalent to a day of sleep and a day of play. Even if she records time with her menstrual cycle, it is not accurate, and even if the menstrual cycle is disordered, it is impossible to calculate the time. Eventually, the woman who underwent the experiment developed psychological problems and gave up after only two months.
It seems that the lack of time will make a person change, and even make a person return to animal attributes, which can also verify that the concept of time has domesticated human beings and allowed human beings to enter the era of civilization. Although time cannot be touched, cannot be perceived, and can only be a concept of conscious understanding, and the understanding of people is not the same, even if a person understands the concept of time in different situations, time seems to have become a kind of sophistic logic, it is change that produces time, not time that produces change. The different mental time produced by people's perception of time seems to be an expectation, an illusion created by change, and with this illusion to see and measure change, together with oneself, is firmly constrained, and therefore cannot be free. Perhaps, physics will transcend time in the future, and psychology will debunk the truth of mental time.
