After the big explosion of the singularity, a vast universe was formed, and there was space-time.
Space-time is a combination of space and time.
Space is well understood, and every land we live on is space, but time is very abstract.
All our actions are inseparable from time, but because it is invisible and untouchable, it is difficult to say exactly what time is.
In fact, time is the manifestation of the movement, the continuity of change, and the sequentiality of the movement of matter.
The determination of time depends on the law of the change of the cycle of matter that is not affected by the outside world.
For example, the cycle of the Earth's orbit around the Sun, the cycle of the Earth's rotation, and the cycle of atomic oscillations.
It can be said that time is a parameter used by humans to describe the process of material movement or the process of events.
Albert Einstein once published his understanding of time.
He believes that time may not exist, and that human beings have been deceived by their own memories.
So, does time exist or not? Is it just a tool that humans use to measure processes?
To prove that time doesn't exist, in the last century, NASA designed and conducted an experiment.
This experiment caused a sensation in society for a time at that time.
What was the conclusion of this experiment?
<h1 class="pgc-h-arrow-right" data-track="27" >, "time does not exist" experiment</h1>
In 1989, NASA and ESA conducted an experiment around the hypothesis that "time does not exist."

Their experimental design ideas are:
In the presence of any instrument that displays time, one can roughly estimate the time at that time according to natural light.
If you block out natural light, the passage of time becomes blurred.
They want to know, can people live in such an environment forever?
They first found a deep cave in Mexico.
The light could not penetrate the cave at all, so it was dark all year round.
Because it is not affected by the circadian rhythm, living in it does not feel the passage of time.
(Cave)
In this cave, NASA built a transparent house of more than 20 square meters.
Inside the house there are household appliances that maintain basic life, equipped with lights with a constant sense of light.
Of course, people not only need to eat and sleep, but also need to have entertainment.
Therefore, the staff in the house is also equipped with game consoles, books, musical instruments, sports equipment and other things for people's entertainment to prevent people from being bored inside.
(Game Console)
However, there are no timekeeping tools in the house, and those inside have no way of knowing the exact time.
After all the preparations were completed, NASA began an open call for experimenters.
They asked the subjects to stay in the cave for 210 days.
As soon as the news was sent, many people became very interested.
Some people are for generous bonuses, others are dissatisfied with real life and want to temporarily escape from a busy society.
As soon as they heard of this great good thing:
Don't worry about eating, don't worry about wearing, don't have to socialize with people, and there are bonuses to take after completing the task, which is the life that most people dream of.
For a time, NASA received so many applications that it piled up into a mountain.
However, they did not accept all the orders.
The cave is only that big, and in order to avoid interfering with the test, only one person can be chosen.
Among these applicants, the experimenter should strictly select an experimenter:
Only people who are physically healthy and mentally strong can be selected as experimenters.
In the end, after a series of rigorous screenings, NASA selected an interior designer from Italy, Follney.
(Foliney)
Foley, like most people who signed up, couldn't stand the harsh demands of work and wanted to find a hideaway and readjust his mood.
The staff conducted a comprehensive examination of Fowlney's body.
After the inspection results are out, it shows that all the indicators meet the experimental requirements.
So Follney was quickly placed in the cave.
<h1 class="pgc-h-arrow-right" data-track="178" >2</h1>
In order to get a real-time picture of Follini's dynamics and physical health, the house inside the cave is equipped with cameras and a series of sophisticated instruments.
When Foini first entered the cave, he was optimistic. Her smiling face outside the cave was impressive.
(Follney who first entered the cave)
In the beginning, Follney's life in the cave was very comfortable. She felt very happy because she had finally escaped from her busy work and gained a short period of peace and freedom.
Follney decided to indulge for a few days, sleeping until he woke up naturally.
When she wakes up, she reads a book or plays a game console while eating;
When she didn't want to read, she played games and played musical instruments.
If she feels a little sleepy, she goes straight to sleep, completely without thinking about time.
House inside the cave
But soon, Fowlney grew tired of this way of life.
Fowlney began to make a comprehensive life plan for himself.
The whole plan has a clear schedule for how long to read the book each day and how long to exercise.
After making the plan, Follney's life in the cave was obviously much more regular, and he was able to study and exercise according to the plan.
Later, due to the gradual disorder of the biological clock, Foliney's perception of time became more and more dull.
Sometimes, she felt that she had read a book for hours, but in fact the time had only passed for more than half an hour;
And sometimes, Fowlney thinks he's done the day's workout. But in just a few hours, she thought the whole day had passed and started the next day's exercise plan ahead of schedule.
With no one to speak in the cave, Fowlini felt increasingly lonely.
She gradually developed an emotion of being abandoned by the world.
Soon after, Fowlney abandoned his daily promotion plan.
This is certainly not because Ofilney's self-control is not good, after all, Foliny is a positive and optimistic person when he is outside the cave.
This is mainly because Fowlney's biological clock has been completely disrupted.
Sometimes, she sleeps for two or three hours and wakes up to start the day's activities;
Sometimes, I would sleep for a whole day or two.
Follney's physical condition deteriorated day by day, and her psychological state was also very poor, always suspicious of ghosts.
To estimate the time, Fowlini thought of using her own menstrual cycle.
However, as Follney's physical condition began to deteriorate, her endocrine system was also disturbed, which in turn affected the menstrual cycle and became less regular.
So, after this life lasted for a while, Follney had no idea how long time had passed, and lived entirely on his own intuition.
Seeing that Follney could not continue, in order to prevent accidents, after some discussion, the researchers chose to terminate the experiment.
In the end, Follney spent only 130 days in the cave.
According to the original plan of the experiment, the experiment was carried out for 210 days, while the actual implementation was a full 80 days shorter.
(Newspaper reporting on the experiment)
However, this figure is already very surprising.
After all, Foini is a person with good physical and mental qualities, and if he is an ordinary person, it is probably difficult to persist for so long.
With the help of the staff, Foley left the room and climbed out of the cave, which was more than 30 meters deep.
When she came to the ground, everyone was amazed by her withered state.
This is in stark contrast to her energetic mental state when she first entered the cave.
In the eyes of many people, this cave is simply a paradise on earth.
No one could have imagined that the optimistic Pfellney would be tortured into this look.
(Foliney after the hole)
The experimenter asked Fowlney: How long do you think you stayed in the cave?
Follney replied stunned, "More than sixty days!" ”
Apparently, her sense of time had been completely confused, and it was not clear how long the real time had passed.
After returning to society, Foley's body gradually recovered after a long period of recuperation, but her psychological condition did not recover for a long time.
Fowlini often felt a strong sense of loneliness in the middle of the crowd.
The feeling of being abandoned by the world has always surrounded her, making her nervous and suspicious.
This experiment caused great changes to Follney, and had a series of bad effects.
However, Follney's sacrifice did not bring much value.
This experiment is actually difficult to prove whether time exists or not, but the results of the experiment more reflect the importance of "time" to human life.
If people do not live according to the rules of time, human body functions will fall into a state of disorder, and eventually people's spirit and body will completely collapse.
Of course, this experiment also has a big drawback, that is, Follney is alone in the cave.
Man is a social animal that needs help and contact with each other in order for a normal life.
If people are isolated alone, they will feel deeply lonely and helpless.
This deteriorating mood also greatly deepened the side effects of the experiment.
Because of this, the variables of the experiment cannot be determined, so accurate experimental conclusions cannot be drawn.
So, are there other ways to prove that time exists or not?
<h1 class="pgc-h-arrow-right" data-track="179" > third, the hypothesis about time</h1>
There is a physics professor in Canada named Lee. Schmoling.
In his work The Rebirth of Time, he mentions that the core of the understanding against the existence of time is based on the way we understand the laws of physics.
In these laws of physics, time is just a trick to getting the equations to come up with an answer.
He argues that physical formulas do not prove that time does not exist.
More than three hundred years ago, the great physicist Newton also tried to explain the universe in terms of gravity, and the result was that the formula lost its role in dealing with infinite space.
In the 1960s, physicists also tried to use quantum mechanics to prove that time exists or not.
(Quantum Mechanics)
American theoretical physicists Wheeler and David applied the theory of quantum mechanics to the universe and successfully derived an equation that was almost terrifyingly complex.
This equation describes the true nature of the universe according to quantum theory.
In this equation, however, the physical quantity of "time" is absent.
Professor of Physics at the University of Oxford in the United Kingdom, Julian. Barber spent a decade studying wheeler and Davitt's formula.
Eventually, he wrote a book called The End of Time.
Although Wheeler and David used quantum mechanics to prove that time does not exist, there are still many physicists who do not want to believe it.
Until now, they've been looking for fallacies in Wheeler and Davitt's equations.
Since so many physicists are unwilling to believe that time does not exist, it is even more difficult for us, the masses, to accept it.
We start as an embryonic cell and grow into an adult form that can think freely and move freely.
This long process is accompanied by the passage of countless times.
Since we can clearly perceive the passage of time, how can we feel it if time does not exist?
To illustrate this question, I am afraid that it is necessary to prove whether "consciousness" exists or not.
And this is a complex and difficult problem.
<h1 class="pgc-h-arrow-right" data-track="180" > summary</h1>
Whether time exists or not is a question worth exploring in depth, and it remains to be continued by future scientists.
But our lives are very short, and there may be only a moment in the long river of time.
The great writer Tolstoy once said in "The Road to Life":
"We often say that time passes. This is not true. It is not time that passes, but us. When we were on a boat on the river, we felt that it was the riverbank, not the boat we were on. The same is true of time. ”
So now, all we can do is cherish time and do more beneficial things.
