Where does time come from and where does time come from?

The most widely accepted physical theory of time is Albert Einstein's theory of relativity. In the theory of relativity, time and space, together form a four-dimensional space-time, which constitutes the basic structure of the universe. Time and space are not Einstein's absolute, and the passage of time measured by observers at different relative velocities or at different measurement points of different space-time structures.

Special Relativity ** The time lapse of a clock with relative motion is slower than that of another stationary clock. In addition, the gravitational field generated by the mass of general relativity** will cause a distorted space-time structure, and the time lapse of a clock near a massive mass (e.g., a black hole) will be slower than that of a clock at a distance from the massive mass.

Existing instruments have confirmed the accuracy of these theories of relativity with respect to time, and the results have been applied to the Global Positioning System.

As far as today's physical theories are concerned, time is continuous, uninterrupted, and has no quantum properties. However, some theories that have not yet been proven to combine the theory of relativity with quantum mechanics, such as the theory of quantum gravity, string theory, and m-theory, predict that time is discontinuous and has quantum properties. Some theories speculate that Planck time may be the smallest unit of time.

According to Stephen W. HawkingHawking) solves Einstein's equations in the general theory of relativity, showing that time in the universe has a starting point, starting with the Great Thunderbolt (or Great **), and the time before that is meaningless. Matter and time and space must coexist together, without which time is meaningless.

From the beginning of mankind, people know that time is irreversible, that people are born, grow, age, die, and there is no other way around. The glass bottle fell to the ground and broke, and the bottle jumped up from the ground without breaking and snapped up. From the point of view of classical mechanics, the irreversibility of time is inexplicable.

There is no substantial difference between the processes of the elastic collision of two particles. The irreversibility of time can only be explained theoretically from the point of view of statistical mechanics and thermodynamics. The second law of thermodynamics says that in a closed system (we can think of the universe as the largest possible closed system) entropy can only increase, not decrease.

Entropy in the universe cannot decrease when it increases, so time is irreversible.

Time is a unique product of human beings, a rule set for a better life and production.

For the universe itself, there is no time.

Idealism can break the shackles of time.

At present, only a few people in the world can understand the answer to your question.

Sorry, I'm not Einstein.

Actually, I am skeptical about the existence of time

Personally, I think it's the changes in everything that create time. If everything is static, then how can you tell time?

Time and space exist for matter.

From coming out to going to where you go, just like life, it is a cycle in itself.

Time comes from your own actions, and it goes from your actions. It's up to you how you grasp it.

The one who doubts time, your mind is on a higher level!

Time is the process by which things evolve. It is a natural existence. It's just that people record it because they need it.

The sun rises in the east and sets in the west as a day, the winter goes to the summer solstice as a year, and people's birth, old age, sickness and death are a lifetime. With the development of productivity, people have the need to keep track of time.

In the Han Dynasty, while using the "100-minute system", the "solar azimuth timing" method was used to measure the length of the sun's projection with a gui watch to judge the time. The table is composed of two parts: one is a benchmark or stone pillar that measures the shadow of the sun standing upright on the flat ground, called a watch; One is the stereotype for measuring the length of the shadow in the direction of due south and north, which is called gui.

Since the shadow of the sun can be measured in units of length, there is a saying that "every inch of time is an inch of gold". Each position of the sun measured by the watch gradually has a fixed name, which is the origin of the hour.

In ancient times, there was no clock, and the ancestors lived a farming life of "the morning light is desolate, and the moon and lotus hoe return". In the years of hard work, the ancestors glimpsed the laws of time from the changes in natural phenomena. According to the "Historical Records", the Yellow Emperor made Xi and Zhan Ri (measuring the shadow of the sun), and the astrological qi (stargazing) in the Xuan District.

Thus began to have the concept of time.

Time should be greater than the universe.

1. The beginning of timeWe can't define time, but time gives us the meaning of life. The universe is the endpoint that best explains the existence of time, and it is also the basis for our current cognition to best explain time. After all, people's cognition is limited, for example, reading history books, there are also nodes one by one, and the history of the Ming Dynasty does not say what happened in the Tang Dynasty, and the history of the modern era will not mark the history of the Warring States.

Therefore, we can only explain the years from that time to the present day through the big **, and then use time to define the process. If you go back to the big ** before, it is impossible to explore the source of time at all, because the previous things are unsolved mysteries. <>

Second, the universe has no time limit, and the universe has reached its current state through rehearsals over a long period of time, and the universe began to form from a small singularity. In fact, there is no specific inducing factor, but because of the effect of gravity and the continuous compression and expansion of the universe, it naturally produces a large **. It's similar to the two rivals who are constantly approaching, and finally the narrow road meets and causes a huge impact, and the universe after the big ** is the starting point of time and constitutes everything in the world today.

There is no time in the universe, but time is the best tool to record what happened, and the years of the universe and the past and the future. <>

3. Time gives meaning to life in the universe space and time.

It's all meaningless, but this has a human civilization on the earth.

time has full meaning on the planet. Because of the loss of time, people will not know the past and the future, nor the passage of years, or even the age of age. Daily life and productivity.

will be severely disrupted, the biological clock.

It will also fall into chaos. WhileWhat exactly is time, this is also oneUnsolved mysteriesBecause we are now confined to a limited universe and do not have enough knowledge to deal with this problem.

Time has existed since the existence of the Milky Way, and the beginning should have begun with the formation of various planets, including the Earth, after the end of the Great Explosion.

Chiropractic scientists once said that time is just an illusion for people, a criterion that is used to facilitate their own lives. The beginning of time begins with the beginning of the life of the socks.

Time has always existed, and the beginning of time is for human beings after they have the concept of time.

Time is an objective existence. The concept of time is the result of human cognition, induction, and description of nature, and its original meaning originally refers to the change of seasons or the reincarnation of the position of the sun on the ecliptic. "Guanzi Mountain Quanshu" said:

time, so remember the year also. With the deepening of understanding, the concept of time covers all visible and intangible movements.

Visible time is used to describe the unified property of all motion processes, which is the connotation of time. Because the problems studied by ancient people were basically macroscopic, rough and slow-paced, they only paid attention to the problem of "time", and later because of the need to study fast and instantaneous objects, the concept of "between" was added, so that time covered the continuous state and instantaneous state of the motion process, and its connotation was finally enriched and perfected, and the word "time" was finally finalized.

Time is created from the earth. This can be explained scientifically.

Time is actually a law derived from the rotation of the earth, its revolution and the movement of the sun.

Time comes from space and speed
