How much do we know about the theory of relativity? How many people still understand the theory of r

Newton, relativity, superstrings. All of them are only summaries of the understanding of a certain stage, and although they are in line with current observations, they are not necessarily the truth. These are very mysterious things, and you don't need to fully understand them.

Now the macroscopic theory of relativity and the microscopic quantum theory are not in harmony. That is, sooner or later, a more esoteric theory will replace it. In his later years, Einstein searched for this harmonious unified theory, but unfortunately died of old age before it was completed.

It is important to know that "understanding" is relative, and without a recognized definition, there is no consistent conclusion.

If you don't realize that "understanding" is relative, first unify the definition of understanding, and then draw conclusions to explain why you understand 5%, then you can't even understand 5%.

If you can't recognize the relativity of relative words, you can't understand the theory of relativity.

Is it necessary to understand? There are many problems that cannot be solved by the theory of relativity.

Maybe it will be included in a theory in the future, and it will become a classic like Newtonian mechanics.

Do you think this is solved by the theory of relativity?

I don't know how you calculated 5%, but it doesn't matter, if your teacher can calculate it, then he understands more than just 5%.

Don't think of the theory of relativity as absolutely true Just like Newton's classical mechanics, science is always moving from truth to error. As long as you have been to college, you should have no problem understanding it.

But it's harder to get sperm.

In the final analysis, Einstein himself was not engaged in mathematics, and the mathematical part of the theory of relativity still turned to his friends who were engaged in mathematics. ** At that time, only how many people in the world could understand the theory of relativity, not because physicists couldn't understand it, but because they didn't want to accept it. It's like a religious who suddenly asks him to convert, and he will definitely not accept it.

As for now, the theory of relativity has become part of the textbook, and there is no question of opposing different beliefs. Those who are engaged in physics research and are not born in theoretical physics must systematically study the special theory of relativity, which is the basic skill of modern physics research. As for those who engage in theory and generalization, that is a compulsory course for them.

The theory of relativity is, after all, an idea, not a statement. Speech can be distinguished by understanding or not, while ideas can only be distinguished by whether they are accepted or not. Understanding the theory of relativity is only the most basic step, how to combine the theory of relativity with other theories?

After the emergence of quantum mechanics, how to regulate the contradiction between quantum mechanics and relativity has become a major topic in the study of near-theory physics. Thousands of physics doctors, graduate students, and professors rely on this thing for food. So if you ask me how many people can understand the theory of relativity, I tell you, these people can understand it, and they are all trying to break through the theory of relativity and improve the theory of relativity.

The basic assumption of the theory of relativity is the principle of relativity, that is, the laws of physics and the choice of frame of reference, the non-massive object distorts space-time and changes the direction of travel of the object.

Close. The difference between special relativity and general relativity is that the former deals with the laws of physics between frames of reference (inertial frames of reference) that move in a uniform linear line, while the latter generalizes to frames of reference with acceleration (non-inertial frames) and is widely used in gravitational fields under the assumption of equivalence. The theory of relativity and quantum mechanics are the two fundamental pillars of modern physics.

Classical mechanics, which is the foundation of classical physics, is not applicable to objects moving at high speed and in the microscopic realm. The theory of relativity solves the problem of high-speed motion; Quantum mechanics solves problems under microscopic subatomic conditions. The theory of relativity subverts the "common sense" concept of the universe and nature, and proposes new concepts such as "relativity of time and space", "four-dimensional space-time", and "curved space".

The special theory of relativity was proposed in 1905, and the general theory of relativity was proposed in 1915 [Einstein completed the creation of the general theory of relativity at the end of 1915 and officially published the relevant ** in early 1916]. Since Newton's laws pose a difficulty to the special theory of relativity, i.e., any object in any position in space is subject to force. Therefore, there are no inertial observers in the entire universe.

In order to solve this problem, Einstein proposed the general theory of relativity. The most well-known corollary of special relativity is the mass-energy formula, which states that mass increases with increasing energy. It can also be used to explain the enormous energy released by nuclear reactions, but it is not what led to the creation of the atomic bomb.

Gravitational lensing and black holes, predicted by general relativity, are consistent with some astronomical observations.
