We don t have anyone here who understands the true meaning of the theory of relativity

That is to say, everything is relative, there is life and death, and so on.

I think the theory of relativity means that the existence of one thing can prove the existence of another, for example, whether a person has money or not, he does not know it just by looking at himself, and he has to be compared with someone to show whether he is rich or poor......But being rich or poor is also relative, because you are rich compared to this one, but you are poor compared to the other, so you yourself have not changed, but the results obtained by the relative are really different, so there is no absolute ...... in anything

In the eyes of human beings, the earth is very large, and a hundred years is a long time. But from the perspective of the universe, the earth is just a speck of dust, and a hundred years is just a moment. This is the relative of space and time.

But the earth is still like that, it won't be big because you're from a human standpoint, and it's not small because you're from a cosmic standpoint. A hundred years will not be long because of human beings, nor will it be short because of the universe.

Time and space are certain. The position is different from that, and there is a relative!

To put it simply, the theory of relativity denies Newton's classical physics and explains the universe on a macroscopic scale.

It is mainly based on the "constant speed of light", which overturns the traditional belief that universal time, that is, as long as there is relative motion between objects, their time lapse is different, such as the "twin paradox" and so on.

General relativity adds "large masses and energy bend time and space" to explain the phenomenon of light deflecting near large stars.

One of the corollaries is e=mc2, which is the mass-energy formula.

Narrow: Explain the relationship between the time and length of object A and the time and length of object B and the time and length of object B if object A moves in a uniform straight line with respect to object B. And give the formula.

Generalized: Explain that if object A moves with respect to object B in an accelerated motion (case x), the curvilinear motion (case y)...It's also that relationship).

Explain that if object A is in the gravitational field, object B is not (case Z).is also that relation) and points out that case xyz is equivalent (i.e. case x can be seen as case y, case y can be seen as case z, and case z can be seen as case x).

Give the formula.

Einstein's theory of relativity is wrong, in general, the speed of light does not change, but Einstein regards time and space as matter, which is not right, time and space are not matter, or even non-existent, there is only matter in the universe, and matter is moving at different speeds, so matter and motion are eternal, and everything else is an artificial virtual quantity, just for the convenience of measurement (the kid dares to guess, but it is the result of careful consideration, friends who are interested in in-depth discussion, you can leave a QQ number, Contact).

Hehe, it's too complicated for everyone.

The meaning of the theory of relativity is that the essence of things does not change, but everyone has a different view of things, and the things have different expressions. The reason why it is said to be "relative" is because it is relative to a certain person.

I wonder if I can get points like this? Oh, thank you!

Rewinding time does not mean that we can go back to ancient times, but we can only become younger, but it is impossible, we cannot reach the speed of light, let alone the speed of light.

When you reach sub-light, you think that time will not pass and you will never grow old.

To see the people or things of the Tang Dynasty, it is impossible to change history!

In fact, the theory of relativity is the theory of physics that studies the relative relationship between time and space.

Personally, I think that the theory of relativity is only temporarily correct today, it is based on the constant speed of light, and the fastest in the world is light? Now it turns out that it is, and only temporarily, that over time the theory of relativity will really become so-called"Relatively", that is, only within a certain range, just like Newtonian mechanics, and may even be judged as a fallacy later, just as everyone used to think that geocentrism is correct.

If this question needs to be from a physical point of view, please ask it from a physical point of view, if it is from a philosophical point of view. As it was said upstairs.

In classical mechanics, the mass of an object has nothing to do with the speed at which it moves.

Many questions are also raised, such as, if human beings go back in time, how will human actions affect their own existence if they disrupt the continuity of history?

What is the space for distortion due to mass?

In fact, I have a vague feeling that the power to explain the nature of the world has quietly shifted from philosophy to physics. This is the thinking that the theory of relativity induces.

If a science has been wandering for a long time, then the science may have come to a relatively complete level, but has philosophy come to an end?

The theory of relativity asks philosophy"What else can you do to help science? "

If you sit on a fire, then a minute is a year for you, and if you are with a beloved woman, then a year is a minute. To put it simply, this is the "theory of relativity".

There are entirely new ways of understanding the universe, such as the analysis of gravity (gravity is due to the distortion of space, not the real force).

I think it's similar to karma in Buddhism.

There is a yes and there is a negation.

Right and wrong, yes or no, is a very clear concept.

Things themselves are made up of many opposites.

Analysis is easy to do, hard to do.

What kind of person what kind of understanding! The theory of relativity applies equally to people.

The younger brother understands: the relationship between one and two"

3: 1 or 2

Relative from the surroundings. Relative from itself.

It is said that there are only three people in the world who understand the theory of relativity, but Lao Ai said, "Impossible! "Because you can't have three

The speed of movement is related to the weight, so it is impossible to turn back the clock.

Jump out of the original definition and come up with new insights!

What does it really mean? The landlord is a high learner.

The simplest way to understand it is that a speed beyond the speed of light (3000000000 meters per second) can turn back time.

This is already the content of the general physics course at the university. Can the average person understand a cutting-edge subject?

There are no more than twelve people in the world who can understand it. Although I have seen it, my one-sided understanding may be negative for you. If it's a real interest, it's recommended to watch it yourself, really, it's quite interesting to watch it yourself.

If you want to understand the theory of relativity, you must first learn advanced mathematics, such as calculus and Riemannian geometry, otherwise you can't understand the equations of general relativity, let alone understand them, and you can learn classical physics well, after all, the theory of relativity is a further extension of it.

There are not many things you need to know about special relativity, and in mathematics, junior high school algebra is enough, and if you want to see more clearly, it is better to learn a little bit of knowledge of matrices in linear algebra. It is enough to physically understand the concepts of velocity, position, time, frame of reference. The difficulty of relativity is not in prior knowledge, but in breaking the inherent concept of time and space, as long as you accept the premise that the speed of light is constant from any frame of reference, everything else will be more logical.

Einstein's research on the theory of relativity is to use a mathematical formula to describe the physical theory, there is no need to learn the general theory of relativity, Einstein himself has not studied it thoroughly (no one studies it now), the special theory of relativity only needs calculus in college mathematics, of course, college physics must be understood. Nowadays, most theoretical physicists are working on string theory, and there is a movie "The Elegant Universe" that introduces this, go check it out, I think you will enjoy it.

To understand the special theory of relativity, it is necessary to grasp the basic relations and formulas of velocity, acceleration, force, time, displacement (Newton's three laws, etc.);

As for the general theory of relativity......That's a lot, mathematically at least Riemannian geometry, physics ......I think it's better to forget it.

Read a sentence first: the moving ruler becomes shorter, and the moving person lives longer.

Remember one more thing: it is impossible for any object to move faster than the speed of light, and then combine it with the core velocity formula of the theory of relativity.

You'll have a rough idea of the theory of relativity.

First of all, crazy fascination, in non-stop thinking, thinking, if you are interested in mathematics, physics and many aspects, you will not worry about what to read, because the theory of relativity and those basic knowledge is as magical in the hearts of people who have not learned, don't read for the sake of reading the theory of relativity, you must really fall in love with everything in nature, there are very few people in the world who can read the theory of relativity, but only if you really fall in love, there is a good saying: intentionally plant flowers and flowers do not bloom, unintentionally plant willows and willows!

Learn classical physics first, the theory of relativity is a promotion of classical physics to a certain extent!

Don't rush to read. The theory of relativity is not very simple, and most people don't understand it very well (although it is taught in high school and college).

If you are really interested in physics, it is recommended to study hard now, take the high school entrance examination with competition learning, and study physics competitions, which will definitely be good for you, regardless of whether you can win the first prize in the future. (In this way, the special theory of relativity must be learned, because it has to be examined).

Maybe you'll choose physics as well.

It should be fine to read the special theory of relativity.

I don't know what general relativity is all about.

Don't limit yourself to other people's boxes, what age and whatever.

If you really want to learn and are interested, no one can stop youNot to mention acceleration or anything.

Believe in yourself!

The special theory of relativity is actually not much of a physical problem, it is a philosophical problem, let me remind you first, it depends on understanding to understand or not... And I always feel that special relativity belongs to the things that the benevolent and the wise see, and everyone understands it differently... General relativity really doesn't have the ability to understand that...

Let me remind you again, if you want to learn special relativity, don't read "A Brief History of Time", especially don't believe the example of the twins, anyone who has a little brain and knows a little physics can find that it is nonsense

It is impossible to fully understand the physical content. Let's read some popular science books first, such as the "First Push Series", which has both quantum mechanics and special and general relativity. At least two episodes have been published, and there are more than n copies. Not only physical, but also mathematical.

The special theory of relativity can be read a little, and the broad sense is...

When you're in high school, you can read it.

Because I didn't learn anything about acceleration, gravitation, circular motion, etc. in junior high school.

Hehe... I've been through it too, good luck! You'll understand!

It is not difficult to understand the special theory of relativity, I read it in my third year of junior high school, and at that time I believed that I could understand 50% of the principle. As long as you have the patience to understand, but because the results of the theory of relativity are somewhat different from the results of our daily experience, we need to reason absolutely rationally. The second is mathematical deduction, special relativity is not difficult, difficult in general relativity, because the situation is very complicated, such as the general theory of relativity in the middle of the main operation is tensor analysis, someone wrote a doctor**, he just multiplies the matrix of two tensors, on the way if you do not do proper ignorance and approximate simplification (this is one of the most difficult but most useful skills in physical computing, is the essence), there is no way to calculate, but the result took 97 pages to complete, plus the organization wants to test, solve the part of the difficult joint, It took 4 years to double-check.

He used this ** to get his Ph.D. in philosophy, and the matrix multiplication of this tensor is only an operation step in the calculation of the whole predicament.

It's not that people can't read it, it's that physicists are initially unwilling to give up the old concept, the absolute view of time and space. As for the general theory of relativity, it has something to do with the mathematical level of physicists at that time, at that time, physicists were all unfamiliar with matrices, and it was too difficult for you to let him do differential geometry.

Now you don't understand, there are two reasons. Generalized theory of relativity, mathematically abstract manifolds, geometric mechanism properties, vectors on manifolds, tensors, etc. are inescapable compulsory courses.

But now it's not that Einstein doesn't let people understand, it's that there are a lot of people who understand.

Because the mechanism of relativity has not yet been understood, it is only a theory that conforms to the experimental data based on the hypotheses put forward by the experimental data at that time, and no one has yet figured out what the mechanism of this theory is, and only by understanding the basic composition and motion of matter and space can we understand.

I don't understand why so many geniuses understand the special general theory of relativity. So many scientists can't understand it.

Do you know what it means? It's not that you memorize formulas or understand special general relativity based on the explanations of the article.

What's more, using formulas derived from the theory of relativity to verify the special theory of relativity is incomprehensible to copy and paste.

To understand the theory of relativity is that you know the process of his derivation, and what is the derivation based on, and you are not ashamed to say that you understand it.

When you can imagine that the earth is not revolving around the sun, but moving in a straight line in four-dimensional space, you have the basic conditions to understand the theory of relativity.

First of all, Einstein understood.

Secondly, many physical scientists now understand, even if they are not engaged in scientific research, but only some university teachers can understand. For example, the author of "The Three-Body Problem", which has been very popular recently, definitely understands.
