Among the many classifications of science, physics has the highest status, and every progress of human civilization throughout history is inseparable from breakthroughs in physics.
Among the many branches of physics, fundamental physics is the most important, and only when breakthroughs are made in basic physics, other branches of physics are more likely to break through.
After Newton established the seemingly simple laws of motion and gravitation, the first industrial revolution began in full swing soon, and later the breakthrough of electromagnetism and thermodynamics led to the second industrial revolution, Einstein's theory of relativity and the breakthrough of quantum mechanics of the Copenhagen School triggered the third industrial revolution, which together created today's human society caused by the basic physical theory. <>
However, the theory of relativity and quantum mechanics are already a century ago, and most people feel that the frontier of fundamental physics is stagnant like a "pool of stagnant water", which makes people wonder "Is the direction of fundamental physics wrong from the beginning?" ”
Frankly speaking, this idea is very wrong, because there have been some breakthroughs in fundamental physics in the past century, such as the Standard Model theory, etc., but because the degree of "transformation" of these theories is not as good as that of relativity and quantum mechanics, and they are very difficult to popularize science, most people's basic physics memory is still stuck on the theory of relativity and quantum mechanics a century ago.
In fact, the reason why the basic theory gives you the illusion of "stagnation" is that in addition to the difficulty of scientific popularization at the forefront of breakthroughs, the biggest reason is that "the time has not come<>".
Classical physics has gone through more than two and nearly three centuries from Newton to being revolutionized by modern physics, which means that it took physicists so long to reach the "bottleneck" of classical physics, and in the same way, because modern physics was born only a century, physicists have not yet touched the bottleneck of relativity and quantum mechanics.
Therefore, it is normal to say that there is no breakthrough at the forefront of fundamental physics, not some "wrong direction".
-
Basic physics is macroscopic physics, and macroscopic physics has never been able to break through, because macroscopic things are fixed, and human beings are now studying microscopic things, that is, the scope involved in quantum mechanics. Because if human beings want to achieve speed growth and spatial leaps, they need to study more microscopic things, rather than things that people can see, so basic physics is not wrong, but it does not have much value, these are all objective things.
-
From the very beginning, it has been limited by the scope of human knowledge, and it has evolved with human understanding. What is true in what is known to human beings is wrong, and what is wrong in what human beings cannot recognize. Human civilization is still very weak, and it still needs to continue to explore the universe.

Of course, fundamental physics is created by the latest people who study physics, people are not sages, who can do nothing, a scientific research, in the first time there will always be countless failures, so some data in basic physics must be wrong, but we can't be sure now, it needs our physicists step by step to verify whether it is right or wrong.
-
In fact, at the beginning of the most basic physics, then some theories are wrong, and some of its algorithms are also wrong, so to a certain extent, then the basic physics should have a relatively correct conclusion.
-
There is absolutely no such situation, and if there is a mistake in basic physics, then there is no way for other branches of physics to carry out, let alone make a breakthrough.
-
Yes! Who would have thought that the choice of frame of reference would have an effect on the laws of physics, who would have thought that the passage of time would be different in the case of inertial frames, and that the mass and length would change due to the relative motion between the inertial frames! So there is reason to wonder if there are other original theories that are wrong!
-
Indeed, some theoretical foundations are wrong, and the continuation of research is naturally becoming more and more outrageous. Looking at the following two items, the sun's luminescence and heating are not caused by nuclear fusion, but by gravitational focusing. This is true of all shining stars.
Black holes are derived from stars, including red and white dwarfs. This is the most convincing explanation, a major discovery that shook the scientific community. Please search for the headline, "The Nature of the Sun - The Principle of the Sun's Luminescence and Heat", which has a detailed explanation and argumentation, and is undoubtedly the latest research results.
-
The initial theory of the Fundamental Physics Society is wrong, because once the basic problems of these substances are wrong, there is no way to talk about these later breakthroughs under the branch of physics.
-
The theory that has been verified by facts and verified by life is not wrong, and now some people are trying to make thermodynamics a common face. In fact, thermodynamics is a quarter of physical mechanics and can change the face. In the second half of the year, I will publish**.
-
Foundation physics is the "solid stone" of the foundation"People learn physics is to know, scientists are"The combination of application and experiment is the affirmation that scientists give the "conclusive theory" of physics that can be applied to real life. If scientists can't get out of the high end of physics, they don't like to use the science of chemical engineering to explain it.
-
Newton's laws of motion, gravitation, classical electromagnetic field theory, the wave nature of light, particle, relativity, quantum mechanics are all true. The problem is that quarks have problems, all particles are free, only quarks are not, quarks cannot be found in experiments, and there are problems with derivation to the Standard Model. Quarks may not really exist.
-
As long as you can prove what is right, no problem, although it is proposed, as long as you can prove it, and it is proved to be correct, but the fantasy that cannot be proved is unreasonable doubt, and that makes no sense, because you can doubt everything, but that will only make you unable to do anything and even make you mentally problematic. Science is not a religious book that cannot be changed, science is always faithful to reality, and it would be foolish for someone to insist on a falsified theory and refuse to give it up.
-
Yes and no, because the level at that time was there, and if the current field of exploration is still based on the previous theoretical basis, then it is indeed wrong.
-
If you are wrong at the beginning, you will not be able to hold your phone and discuss "whether the theory of fundamental physics is wrong in the first place".
-
The reason for the occurrence of gravitational force (brief description): When the high-energy particles moving in the universe pass through matter (celestial bodies or particles), part of them are intercepted and absorbed to form a weak energy region (Einstein's space-time curvature), which is the gravitational range mv2=e=mv2 (the formula of the law of conservation of energy conversion). For more details, please see the forthcoming gravitational hypothesis, "Elemental Periods and the Causes of Gravitation".
-
It can't be, it was wrong at the beginning, now it's a crash. It is necessary to take a higher level to further understand the matter of time and space. In the future, the understanding of energy will reach the quantum world.
Quantum technology can change the frequency and space-time of matter generation to create the matter we need, and sound, light, electromagnetism, and other phenomena, and these must be accurately named, and the basic parts must be built first. Matter can be created by imagination.
-
It cannot be said that fundamental physics was wrong from the beginning, only that it was very one-sided from the beginning. Why can Fuxi be called a saint and an immortal by the world? Because he stepped into the study of the core problems of science, he focused on exploring the core areas of nature from the beginning, but unfortunately he did not solve the problems of the basic laws of natural development and evolution and the problems of natural methods to solve various problems.
The starting point of physics is the study of one-sided problems, and even Newtonian mechanics starts from the study of the local problem of the relationship between force and motion, and there is no research in the whole physics that starts from solving the basic laws of natural development and evolution. ......

Truth is always the essence of phenomena, and the correctness of a theory is to compare the quantified numbers of phenomena with mathematical formulas and actual observations, so as to verify its correctness!

The theory is correct, the current direction is wrong, the future direction is electromagnetic space, and no one studies the state of life in high and low energy states
-
There are many successful cases of application of Liuton's physics, which have been tested in practice. And the theory of relativity is only a theory until now.
-
Physics is the phenomenon, cause and effect are the essence! Why are scientists so smart, because of good fortune!
-
Maybe it's wrong, but you can't learn the current theory with your IQ.
-
You're like saying that a living person would actually be dead in the first place.
-
It's good that the theory of physics can solve the problem, not right or wrong.
-
Without the saliva of genius, it is difficult to make a breakthrough in basic physics.
-
I don't know about this, after all, it's a fantasy thing.
-
Not wrong, but basic.
-
I don't think it's wrong. Because theory and practice cannot be equated. Many successful theories cannot be put into practice.
-
It can't be, because these things are also the result of repeated practice, and they can't be wrong.
-
No, because if basic physics wants to develop better, it will have to take a long time, so physics is also improving, but slowly and too early. Open the shot.
-
Basic physics is now relatively powerful, all theories are relatively advanced, and the fact that it has not been developed for a long time does not mean that its earliest theories are wrong, and research is a relatively difficult thing and cannot be generalized.
-
In fact, fundamental physics is not stagnant, but because the speed of fundamental physics innovation has been slow in recent years, from the birth of fundamental physics to the present, it has gone through more than three centuries, and scientists have reached a bottleneck period in the study of fundamental physics. Moreover, fundamental physics is the most important premise for the study of physics, and its theory is correct, but scientists have discovered many new theories.
-
The earliest theories were verified by thousands of experiments, and after decades or even hundreds of years of verification, no errors were found, and the development of science is a slow process that cannot be achieved overnight.
-
The fact that basic physics has not continued to develop for a long time shows that it is no longer a necessary product of this new era, and scientific research needs more new inventions and new theories.
-
The fact that basic physics has not developed for a long time may be because it has not kept up with the pace of scientific and technological progress, and it is not necessarily that the original theory is wrong, so the development of science and technology should be accelerated.
-
Theory is a summary of reality and an explanation of nature**, which is not developed from reality, and astronomical celestial phenomena are one of the developments**.
-
Right! It is the earliest, and there is a problem with the most basic principle, for example, is light an electromagnetic wave? Is it a particle, is it a wave?
What does this mean by the double-slit test? This is not the nature of light itself, or is it a man-made term for light. Does light itself have color?
Or is it man-made. What exactly is time and space? Whether the universe is finite or wireless is proven.
-
To find a person with such an IQ that he would not get dizzy even when he sees mathematical formulas, who happens to be born in a country where studying physics is not a crime, who would rather give up finance or politics or any kind of money-making profession to do physics for various reasons, and whose family conditions or social system guarantee that he will not starve to death even if he does physics, and then the society will have to have a way to allow him to publish his results. By such a coincidence, God's creation has only been made up so many times, and now that Schrödinger and Einstein have only passed 100 years, the chances of being so quick are almost the same as touching the heavens and the thirteenth in a row.

I don't think the connection between junior high school and high school is very close, and it's too late to learn junior high school knowledge now. Now you should pay close attention to the knowledge of high school, look at the textbooks of high school, because the general level of textbooks should be able to understand the students, if there is something you don't understand, it is because your junior high school knowledge is not sound, you can ask your classmates to understand, each subject according to this method to preview a chapter, can understand the first chapter of the textbook, basically it's almost the same, if you have spare energy, you can buy an extracurricular book for each subject. You can also find classmates with better grades to study with.
