Can you talk about your understanding and questions about Einstein's theory of relativity?

Can you talk about your understanding and questions about Einstein's theory of relativity? Tell me my personal opinion. First of all, Einstein's "theory of relativity" is mainly formed by the polymerization of substances, that is, metallic hydrogen. "Energy", that is, the formation of metallic hydrogen, are two different concepts and contradictory statements. Secondly, Weinstein's "theory of relativity" is neither suitable nor necessary for us ordinary people, and there is no need to study and discuss it at all.

Einstein's theory of relativity means that everything is relative, not absolute. For example, someone committed a capital crime and regretted asking to donate his organs to those in need before he died. He did not regret doing a good deed before he died, but there were also absolutes. Whoever has a large amount of water and fire wins, and the amount of water goes out, and the amount of fire goes out.

Einstein's theory of relativity needs to distinguish between "matter" and "energy" and cannot be confused.

"Matter" is formed by the polymerization of metal hydrogen; "Energy" is the electromagnetic wave released at the same time when the "magnetic moment" of metal hydrogen cuts and polymerizes to form new elements.

Metal hydrogen is an "excited state" substance-plasma, and "light speed" is the oscillation of "magnetic moment" of metal hydrogen.

Thermonuclear reaction "mass" is conserved, and "matter" will not be converted into "energy"; It can be seen that "substance" is the carrier of "energy", and the so-called "chain reaction" means that the new metal hydrogen polymerized by the fast-flowing "substance" in the shock wave is repeatedly cracked into metal hydrogen, thus producing a continuous explosion.

There is no doubt that relativity.

Seeing through and understanding will be different,

Physical optics is him.

People have been immersed in relativity for a long time. It takes a lot of effort to pull it out of this trap now. Prejudice is the biggest obstacle to scientific progress.

Relativity is divided into narrow sense and broad sense. Today, I only talk about the narrow sense, because my research on the narrow sense is relatively mature.

The connotation of special relativity can be completely summarized in one sentence. The speed of light depends on the inherent properties of the medium that propagates light. As long as we think about this, all the problems of special relativity can be basically solved. There is only one small problem, that is, the mass-velocity relation problem (I have thought about this problem, so I won't talk about it here because it is immature).

As for Lorentz transformation, it is completely redundant. The root of the problem stems from the so-called two dark clouds at the beginning of the twentieth century. At that time, our predecessors imagined the movement of a nonexistent ether relative to the dry earth. However, the above mistakes are only due to the wrong understanding of the nature of light. They equate light with matter. However, the light of matter is different from the movement of matter, and they indiscriminately extend their understanding of the law of material movement to the movement of light. Thereby creating "dark clouds."

The movement of light is very different from that of matter. The most obvious thing is how the speed of light is generated, which is completely inconsistent with the dynamics principle. It is correct that the speed of light has nothing to do with the motion state of the light source and the motion state of the receiving source. But there is a problem that must be made clear. Light is not formed by a force from its generation to its propagation at the speed of light. But the speed of light, so propagation at the speed of light is determined by the nature of the medium. I don't know why, but it is an objective fact. It is for this reason that if we want to consider the conversion of light speed between different inertial systems, we can only consider the propagation medium. Independent of the observer and the receiver.

Looking back, space and time are the basic quantities, and speed is the derived quantity. It is not reversed to determine the basic quantity by derivative quantity. Secondly, when it comes to philosophy, change is absolute, and invariance is relative. An invariant must correspond to some invariance of objective nature.

Thirdly, if there are infinite problems in the equation, we should think that there is something wrong with the physical theory itself.

There is no doubt that we can understand Einstein's theory of relativity.

Relativity says archery on horseback must be farther than archery on foot. So when bidding for a gun, you will run a few steps forward and throw it, because of the acceleration, it will be farther than standing there. However, when riding a horse, the speed of illuminating the target with the open beam is the same as that when standing on the ground with both feet, and there is no superposition speed. Therefore, acceleration can only be reflected in general tangible things, but not whether there is an incidental acceleration relative to light, which is relative. In fact, this is completely correct. If you say why, it's called relativity.

First of all, if it is not called relativity, then light and arrows are not comparable, because archery can superimpose speed, so you can see speed.

Secondly, if it is not called relativity, the superposition speed of light beams is not fast, but the superposition speed of light beams depends on the amount of light energy.

Just like the flow speed of a river, it will not be different because of the size of geographical latitude or the wind blowing into the river in the sky. Its velocity can only be determined by altitude difference and reserve pressure.

So at the same speed, light and arrows can't be compared. Similarly, even if everyone is pursuing happiness, happiness in the world cannot be completely integrated. This is not because of the narrow sense and broad sense, but because there has never been a bridge to connect.

Einstein's theory of relativity has many mistakes, some of which need to be wrong or good.

Time and space can be changed, and there is no absolutely independent and objective time and space.

The constant speed of light introduced relativity. At first, Einstein imagined whether people could see still light if they moved at the speed of light. If people can see still light, it is equivalent to time standing still, which is obviously impossible.

Einstein deduced the speed of light from Maxwell's equations, but this speed of light has no reference, which does not conform to the superposition principle and is too contrary to our common sense.

In other words, no matter how you measure the speed of light, the speed of light in a vacuum is fixed. The speed of a beam of light emitted from a stationary rocket is the same as that of a high-speed rocket.

This can introduce many interesting things, for example, your time is different from mine, and we are in different spaces.

If I do high-speed exercise relative to you, the time for you to see me will slow down, and the time for me to see you will also slow down.

The problem with relativity is that the speed of light is constant, because all the roots of relativity are also that the speed of light is constant.

At present, we don't know the essential reason for the constant speed of light, only that the constant speed of light conforms to the experimental results.

One. Einstein's special theory of relativity.

Einstein's special theory of relativity points out that space and time are not absolute, and two simple principles form the basis of special relativity:

1: one is related to the nature of light, that is, the speed of light is constant, and the speed of light is10.08 billion km/h;

2. Another relatively abstract principle is relativity, that is, motion is relative. This principle is based on a simple fact: whether we discuss the magnitude or direction of speed, we must be clear about the measurer. This is the essence of relativity.

In Einstein's special theory of relativity, the motion of objects is mostly spent in time, not in space. In our general cognition, we all spend time in space. We sat on the sofa watching TV and taking a walk in the street. We live in a three-dimensional space, which is easier for everyone to understand. But Einstein regarded our time as the fourth dimension of the universe, and we actually live in a four-dimensional universe including the time dimension. For example, if we meet a friend somewhere, we will not only determine the three-dimensional space of both sides (that is, where), but also make an appointment, such as meeting at 4 pm.

Here, Einstein unified the concepts of time and space. In the dimension of time, when an object moves relative to time, its speed in time also slows down. Everything in the universe always moves at a uniform speed in time and space (light speed), and the speed of the sum of our three-dimensional space and one-dimensional time is light speed. But the speed of moving objects in our daily life is much less than the speed of light, so we can't feel the existence of relative effect. How do you explain this?

Adding an object is static (relative to us). That is to say, it is motionless in space, so relative to us, the speed of motion of these objects in space is zero, so we have the same speed of light as these objects in time dimension, so we will grow old at the same speed as them. But the other side. If an object is moving relative to us, such as a car passing by us, then the movement of this object means that its speed in space is greater than 0, so it will be less than the speed of light in time, because part of its movement is transferred to space. In other words, when an object moves in space, its time will slow down.

The theory of mass-energy equivalence is the most important inference of Einstein's special theory of relativity, that is, the famous equation E=mC? Where e is energy, m is mass and c is the speed of light; In other words, all matter contains energy whose mass times the square of the speed of light, which can explain why the speed of an object cannot exceed the speed of light.

All the energy of a stationary object is contained in its stationary mass. Once in motion, it will produce kinetic energy. Because mass and energy are equivalent, the energy in motion should be added to mass, which means that the mass of moving objects will increase. When the moving speed of an object is much lower than the speed of light, the added mass is very small, for example, when the speed reaches 0. 1 of the speed of light, the mass will only increase by 0.5%. However, its increased quality is remarkable. For example, when the speed reaches 0.9 of the speed of light, its mass more than doubles. At this time, the object needs more energy to continue to accelerate. When the speed is close to the speed of light, its mass increases linearly with the increase of speed. When the speed is infinitely close to the speed of light, its mass tends to infinity, which requires infinite energy. So nothing can move at the speed of light. Only particles with zero mass can move at the speed of light, such as photons.

Two. Einstein's general theory of relativity

Einstein's special theory of relativity explains the essence of time, space and light, and declares that the speed limit of everything is the speed of light, but this leads to another problem: the concept of taking the speed of light as the speed limit of objects is incompatible with Newton's theory of gravity put forward in the late17th century, because gravity can spread directly in two massive stars in an instant. In other words, the speed of gravity should exceed the speed of light. After years of research, Einstein put forward the general theory of relativity. In this theory, he completely changed our concepts of space and time again. He proved that they are curly, and gravity is these curly waves.

Newton believed that the attraction between two objects depends on two factors: the total amount of matter that makes up each object and the distance between the objects. The greater the mass of an object, the greater the gravity, and vice versa. The equation for accurately calculating gravity is given, which is called the law of gravity. Until the beginning of the 20th century, the law of universal gravitation was recognized as an irrefutable truth.

But Einstein's special theory of relativity puts forward that the speed of light is the maximum speed of everything in the universe. But according to the law of universal gravitation, the gravitation between two objects is related to the distance. It is conceivable that after the sun suddenly explodes, the earth with the principle of1.500 million kilometers will immediately leave the sun's orbit, but it takes 8 minutes for light to travel from the sun to the earth, that is, the gravitational speed exceeds the speed of light, which obviously contradicts Einstein's special theory of relativity.

When there is no object or energy, space should be flat on the two-dimensional plane. But on this two-dimensional plane, if there is a massive object, it will make the plane sag, just like a ball falling into a net. The earth revolves around the sun, as if there is a rope connecting the earth and the sun. In fact, the earth is involved in the orbit of the sun's sinking space. We call this phenomenon gravity.

So the mysterious force that leads to the attraction between the earth and the sun is the existence of the sun, which leads to the bending of space. So Einstein's general theory of relativity combines the curvature of space to explain the role of gravity, and expounds that the driving force of gravity is the structure of the universe. So according to this theory, if the sun explodes, we still need eight minutes to know the fact that the sun explodes because of gravity.

Most people understand the logic of Einstein's theory of relativity. Unfortunately, this inversion of logic is the foothold of Einstein's originality, and because of this, he resolutely broke off relations with Lorenz, Poincare, Fitzgerald and Havishand, all of whom had some theoretical achievements before him.

The misunderstanding of relativistic logic also leads people to worry that relativity does not clearly explain how the clock slows down or why the meter scale becomes shorter. At the same time, they also want to know why physicists are always so convinced of the specific theory of special relativity, although at the same time, many other theories have been replaced.

In addition to this most important theory, there is a second theory, which I also call' principle theory'. This theory adopts analytical method, not comprehensive method. Its basis and starting point is not the principle of hypothesis, but the general characteristics of natural processes and the criteria for generating mathematical formulas obtained through experience, and every natural process and its theory must also be satisfied.

Therefore, thermodynamics deduces the necessary conditions for the impossibility of perpetual motion machine from general empirical facts by analytical method, and these conditions must be met by independent events. The advantage of constructivism lies in completeness, adaptability and clarity, and the advantage of principle theory lies in perfect logic and reliable foundation.

The method and principle of construction are the differences between Einstein's thought and his predecessors. Lorenz, Hayvihid and Poincare combined the constructivist theory of known physical theory when trying to explain the invalid results of ether drift experiment. That is to say, they studied the electromagnetic equation constructed under the static frame of the ether, and then calculated that an object like a charged sphere may change its shape when it is excited in the ether (hence the Lorentz contraction phenomenon).

Einstein did something completely different. He didn't start with the physical laws constructed in the Ethernet framework, nor did he use them to construct micro-physical structures to explain the undetectability of the framework, but turned the whole problem upside down. In other words, he assumed that this kind of undetectability is indeed universal, it is indeed a part of the laws of nature, and promoted it to a principle. According to the principle of relativity and the hypothesis of light, Einstein went on to deduce what these two characteristics mean to the laws of physics. In his paper 1905, all the above contents were constructed in one page, and the rest were used to derive the results, which were very common in later mechanics and electrodynamics (the main structural theory at that time).

Mathematicians should realize that Einstein's principles and methods are similar to the logical structure they deal with. Based on some premises, they can draw general conclusions, and these conclusions are accurate and effective only in the field of these premises. A typical example is of course Euclidean geometry (ironically, relativity finally got ahead of Einstein).

People who don't admit that relativity is a principled theory may be quite confused. Physicists are prepared to put almost everything on the lasting validity of Lorenz covariant concept for a century, while seemingly similar (constructive) theories are constantly being replaced. There is a difference.

China people say: Everything has two sides-patriotism is a blessing (always remembered in the hearts of the people of China), and trial is an evil reward (always being a slave). Only when you are determined to be in a good position in life can you have a bright future, and wisdom will create a better life in the future. Some people always try to find a way out through speculation: the result is just the opposite-everything will go to zero in the end! As you sow, you reap: plant kindness and reap the future.
