What is time, can time be stopped, can time be turned back

1.Well, you have a certain understanding of time. Time out of matter is meaningless. But you can't say that. It can be said that the movement of matter produces time.

2.Time can be stopped. According to Einstein's theory of relativity, the closer an object is to the speed of light, the slower time becomes. When the speed of an object is infinitely close to the speed of light, time is almost at a standstill.

3.Time can theoretically be turned back. This requires the perfect combination of quantum mechanics and relativity! But not now. In addition to exceeding the speed of light, it may also be possible to achieve it through space wormholes, black holes, and white holes (detailed theories are not clear in a moment).

4.Whether people can transcend life and death can be said to be not the category of time, but the category of biology. Human mortality is most likely the result of a genetic defect.

Now that we have discovered the material that can repair genes, when will we be able to achieve immortality? There may be a long wait.

5."Man can go back in time, but only in a relative position, as in the earth. Because in order for matter to move backwards, it takes external energy.

Time cannot bring the universe back in time. "This question is completely wrong for you to associate with! Completely ignorant of the concept of space.

We are traveling through time and space, not rewinding matter!

6."After returning to the past, history will not repeat itself, that is, once you go back to the past, you cannot go back to the present, because the addition of your relative matter will make all the substances affect each other and change, affect the movement, that is, affect time. "You're talking about the "chaos effect" (the effect will continue to expand and eventually become chaos), and this is possible.

Actually, no, as I said above, the "past" we want to visit is not actually formed by our matter regressed, but in our relatively independent parallel universe (entered through a spatial wormhole)! It's okay to go back to our world.

It is not clear what the time is, and there is no need to know.

Time is relative, and when the speed of a moving object relative to you is the speed of light, its time stands still relative to yours, but it does not change for himself. You can't turn back the clock

You just have to wait, when the time machine is born, human beings can travel in different historical time and space on the earth, and the entire history of the earth will become a whole. It's great, isn't it?

O thoughtful man.

You can look at "A Brief History of Time" and the lectures on time at the University of Oxford, all of which are good.

I have a little bit of an idea about rewinding time and I'm going to talk to you about it.

Let's talk about going beyond time to the future, how do you get there, if there's something like a time machine, you sit on it. Three minutes later, you're three years later, so that's to say, three minutes have passed inside the machine and three years outside. I think if you think of the trajectory of time as a spiral, then if you can cross it in the middle (the path becomes a straight line), then you can do it.

But going back to the past, there is a problem, your time in the machine is forward, and the outside has to go backwards, so how to do it, if it is also backwards in the machine, then if the machine is exactly three minutes ago, then retreat to that point, you don't have your time machine, how to go back? There are other well-known paradoxes that I think will never go back to.

Mathematically, time is an illusion. In a letter of condolence to Besso's relatives, Einstein wrote the following paragraph:"Now, he's one step ahead of me and has left this strange world.

But that doesn't mean anything. For those of us who believe in physics, the distinction between past, present and future is nothing more than an illusion, though sometimes stubborn. Newtonian mechanics, which dominates the macroscopic world, Maxwell equations in the electromagnetic world, and quantum mechanics in the appearance world, all have positive and negative solutions in time, and in words, they cannot distinguish between the past and the future, and time is like an illusion.

Only in the second law of thermodynamics there is an arrow of time, in a closed system, the macroscopic process of thermal phenomena always proceeds in the direction of increasing entropy, and when the entropy reaches the maximum, the system reaches equilibrium. However, the thermal second rate is a statistical law, and it is difficult to imagine that the three laws of the ox and quantum theory, which are the basis of it, can produce theories with time arrows on the basis of the arrow of time.

So time may really be just an illusion, something that comes out of thin air in the human brain.

From the perspective of conservation of matter, it can transcend life and death. The body and body are wiped out, returned to the earth, and reconstructed into external objects. Soul? Is the soul an illusion or an existence?

In the current theoretical situation, it is theoretically possible to go back to the past, but in practice it is impossible to happen. It's like theoretically you can read all the books about time one at a time, but your reading speed is slower than the publication of the books in question, so it's theoretically possible, but technically impossible. To go back in time, you need to build an accelerator bigger than the Milky Way.

The key is the technology under the current theoretical system.

When there is a change in the new theoretical framework, as was the influence of aerodynamics on the invention of the airplane, it may be possible to go back in time.

As for those paradoxes, the answer is logical.

Theoretically, can humanity enter history or the future).

You can look at me another.

It seems that Einstein's theory of relativity can be used by you, so you should study it carefully.

If I were to go back in time, here are a few important pieces of advice I would like to give to myself when I first entered university:

1.Keep an open mind and a positive attitude: Entering university is a new stage full of opportunities and challenges.

I want to tell myself to keep an open mind and dare to try new things and reach different people. Maintain a positive mindset, have the courage to face difficulties and setbacks, believe in your abilities and keep trying.

2.Cherish time and opportunities: University life is full of colorful activities and learning opportunities.

I would like to remind myself to cherish my time, plan my study and life reasonably, and not waste my precious university time. Seize various opportunities to participate in extracurricular activities, club organizations, internship practices, etc., broaden your horizons and interpersonal network, and cultivate all-round development ability and quality.

3.Establish good study habits: Studying in college will be more difficult and stressful, and I want to say to myself to establish good study habits.

Arrange study time reasonably, do a good job of previewing and reviewing the course, actively participate in class discussions and experimental practice, and improve your learning effect and ability. At the same time, it is necessary to pay attention to cultivating the ability of independent learning and independent thinking, and master the skills of information retrieval and scientific writing.

4.Develop hobbies and social relationships: College is not only a place to study, but also an opportunity to develop personal interests and hobbies.

I would like to say to myself that I want to actively participate in campus activities, club organizations, and volunteer services to develop my hobbies and enrich my university life. At the same time, it is necessary to take the initiative to meet new people, establish good social relationships, and expand network resources and interpersonal skills.

5.Seek support and help: During my time at university, I wanted to tell myself that I was shy and isolated, and that I had the courage to seek support and help.

Both the school and society have a variety of resources and services that can help students solve problems and face difficulties. Actively communicate with teachers, counselors, and classmates to seek their guidance and advice. In addition, take advantage of resources such as the Orange Good Library, Academic Counseling Center, and Psychological Counseling Services to pay attention to your physical and mental health.

These are some of the most important pieces of advice I would like to give to myself when I first enter university. University is a precious stage in your life, and I hope you will cherish this time, strive to grow and explore, and lay a solid foundation for future development.

The song sung by the singer Black Dragon 38 degrees 6

I can't escape you.

Like a fish swimming in the sand.

I know there's no end.

But he is not afraid of bleeding from his head.

Loving you is a mirage.

Swim like a bubble.

Unreal and unwanted.

The first time I saw you, I couldn't speak, and my heart was shaking.

Embrace this oasis with that warm tenderness.

I gave up the whole forest and left behind nostalgia and sorrow.

Like the first time I saw your eyes, time stopped flowingI burned the universe to a temperature like an electric currentAt 38 degrees 6

I can't escape you.

Like a fish swimming in the sand.

I know there's no end.

But he is not afraid of bleeding from his head.

Loving you is a mirage.

Swim like a bubble.

Unreal and unwanted.

The first time I saw you, I couldn't speak, and my heart was shaking.

Embrace this oasis with that warm tenderness.

I gave up the whole forest and left behind nostalgia and sorrow.

Like the first time I saw your eyes, time stopped flowing

I burned the universe to a temperature like an electric current

At 38 degrees 638 degrees

Embrace this oasis with that warm tenderness.

I gave up the whole forest and left behind nostalgia and sorrow.

Like the first time I saw your eyes, time stopped flowing

I burned the universe to a temperature like an electric current

Hug until your head is white and don't let go of your hand.

I have taken off my waiting and all the reasons to love you.

The whole world follows me from night to day.

My only request is that our love stays forever.

At 38 degrees 6

Lyrics: Can't escape from you, like a fish swimming in the sand.

I know that there is no end, but I am not afraid of the blood flow.

Loving you is a mirage, swimming like a bubble.

Illusory and unwanted, the first time I saw you.

It's hard to open your mouth and your heart is trembling, Embrace this oasis.

That fervent tenderness, I give up the whole forest.

Leave nostalgia and sorrow, like the first time I saw your eyes.

Time stopped turning back, and I burned the universe.

The temperature is like a full current, at 38 degrees Celsius6

I can't escape from you, like a fish swimming in the sand.

I know that there is no end, but I am not afraid of the blood flow.

Loving you is a mirage, swimming like a bubble.

Illusory and unwanted, the first time I saw you.

It's hard to open your mouth and your heart is trembling, Embrace this oasis.

That fervent tenderness, I give up the whole forest.

Leave nostalgia and sorrow, like the first time I saw your eyes.

Time stopped turning back, and I burned the universe.

The temperature is like a full current, at 38 degrees Celsius6

38 degrees 6, embrace this oasis.

That fervent tenderness, I give up the whole forest.

Leave nostalgia and sorrow, like the first time I saw your eyes.

Time stopped turning back, and I burned the universe.

The temperature is like a full current, hugging to the white head.

Without letting go of your hand, I took off the wait.

And all the reasons to love you, the whole world follows me.

From night to day, my only request.

Our love stays forever, at 38 degrees 6

We all know that the times and disadvantages are moving forward, and they are all flowing, and it seems that they will not stop, with the passage of time, social development and progress, people will also get old, so many people are very curious, time must go forward? What would it look like if time went backwards? AlthoughWe all know that time may never go backwards, but that doesn't prevent us from having some fantasies.

Many netizens also rented stalls to show their different views on this issueSome people say that if time goes backwards, then everything will come backwards, for example, a person's memory will also develop backwards, and a person's age will be younger and younger, maybe a gray-haired old man will live from 100 years old to 80, 70, 60 years old until he becomes a little baby. Do you dare to imagine this kind of outcome? Actually, if your memory is deteriorating day by day, go back to the past.

Medically speaking, it is also a disease, it means that you will gradually forget more and more, and memory loss is not a manifestation of Alzheimer's disease. <>

Our human beings' continuous research and invention are originally continuous progress with the development of time, making our society more and more developed, making people's happiness higher and higher, if time will go back, then these will no longer exist. We may now have cars, airplanes, and other means of communication.

Back in the old days of horse-drawn carriages, back to the age of walking, we may also go back to the era of Big Brother and then to the age of envelopes from the current Internet age. In fact, if time passes backwards, then our lives will also get shorter and shorter, in fact, time reversal is not much good for us. <>

The world is really big, and humans are amazing, and you see that there may always be some unexpected ideas in the minds of human beings. If time could go back in time, maybe you could do something you want to make amends, maybe you want to make yourself less regretful, but it's just ifs.

First of all, for us, time passes all the time, and at the same time, time cannot be reversed, if time can be reversed, then what happened in history is just a dust branch all over again. However, according to the explanation of the scientific debater Kuanjia, time cannot be turned back. Time is gone.
