After reading this topic, Lao Guo's head went blank, and suddenly he felt that physics was in vain, and he didn't even understand such a basic physical quantity as quality. To answer this question, let's analyze the context of the concept of quality. After all, inertia is directly proportional to mass.
Since Newton published his famous three laws, the definition of mass seems to be conclusive. In other words, quality is a measure of how many substances there are. There are two ways to measure mass, one is gravitational mass and the other is inertial mass, and the measured values of these two masses are equal. There was once a scientist named Efou, who spent 25 years continuously improving the measurement accuracy and proved by experiments that gravitational mass = inertial mass.
However, as long as friends with high school education know, in fact, gravitational mass and inertial mass are not the same thing. This is because the direction of gravity is a force pointing to the center of gravity, which is inversely proportional to the square of distance; Inertia force is only opposite to acceleration direction and proportional to mass. Therefore, neither gravitational mass nor inertial mass expresses the essence of mass.
When Einstein's theory of relativity came out, he took the principle of equivalence as the cornerstone of general relativity. However, this is useless, it still doesn't give what quality is. It's just that Einstein put forward the concept of motion quality and the mass-energy equation E = MC 2, which improved people's understanding of quality, that is, quality is energy. However, even at this point, human beings still have a little knowledge of quality and still have not figured out the origin of quality.
On July 4th, 20 12 local time, scientists from Meyrin, Switzerland held a press conference, saying that a new subatomic particle was discovered, which may be the elusive Higgs boson (also known as God particle). What exactly is this Higgs particle? Does it have anything to do with the quality? Since this article is not about this, let's talk about it briefly.
Now scientists have found all kinds of microscopic particles, all of which have mass, but the mass is different, and the difference is huge, even across 1 1 order of magnitude. The topic of where quality comes from is once again in front of physicists.
The Higgs particle is considered by physicists to be the kind that can be born in a vacuum and disappear in an instant, and it has such a great mass that other particles will produce a sticky characteristic when they contact with the Higgs particle in the process of motion, and the performance of this characteristic is mass.
Not all the mass contributions come from Higgs particles, and neutrinos probably also contribute. When these ghostly particles travel through space, they will switch between three neutrinos. Stranger still, the mass of neutrinos may not even be obtained through the Higgs mechanism. Because neutrinos do not carry any "charge", they are their own antimatter. If so, its mass may come from its interaction with itself, not from its interaction with Higgs field.
If the friends who read this article know something about thermodynamics, then they must know the famous concept in thermodynamics: entropy. Even if you don't study physics, you can understand that this thing is the meaning of system chaos, the arrow of time, and the whole universe shows a trend of increasing entropy. Yes, that's what Lao Guo said.
From the second law of thermodynamics, we can know that the one-way increase of entropy means the irreversibility of physical process, and the essence of free energy is the competition between entropy and energy. As long as the free energy of the system does not reach the minimum, the system can do mechanical work. We define entropy force from here: entropy force is the derivative of free energy f, and entropy force is as real as the force from the interaction energy gradient! Erik Verlinde, a Dutch theoretical physicist and string theorist, clearly pointed out that gravity is an entropy force in his papers such as The Origin of Gravitation and Newton's Law, and pointed out that the mass or inertia of an object is also related to entropy. Einstein's equation is derived by a method similar to black hole thermodynamics.
Anyone who has studied some thermodynamics or statistical physics knows that when the energy of a system increases, the entropy usually increases, so the entropy on the surface will also increase after particles are integrated into the surface. Through the conservation of energy, we know that the entropy force corresponding to the increase of entropy is gravity, that is, particles are always attracted by the space surrounded by curved surfaces. We see that the consequence of thermodynamics is gravity!
It is easy to understand why the universe expands from the point of view of entropy increase, because the surface area of the whole universe increases with entropy increase. Because of the existence of entropy force, it is easy to explain that dark matter is probably a manifestation of the overall entropy force of the universe, which is probably why we can't find evidence of their existence now, because we ignore the entropy force.
According to the theory of evolution, in the whole universe, all existence and modes of existence are embodied in: potential = mass+energy+field, the relationship between conservation and balance, and the process of relationship evolution. The process and way of the existence of the universe is the evolution process of the mutual transformation of potential, mass, energy and field, and the statement that something is created out of nothing is not in line with the facts. From the above description, Lao Guo thinks that what he said may be essentially the same as the entropy force.
It is worth mentioning that Li Bingtie, the founder of Extenics, was born in 196 1 and is 58 years old. He is an engineering engineer and works in Jiamusi Hongji Group Company in Heilongjiang Province. At the age of 2 1, he established the personal amateur research goal-space theory, and established the theory of evolution in 2007, which is a whole and systematic research pool. Evolution is an organic whole and initiated by one person. There is a description of quality in this theory, because Lao Guo didn't study it carefully, so he didn't carry it.
Summary: From the previous discussion, I think you can also feel that although we are gradually approaching to uncover the truth behind quality, the road ahead is still far away and the road ahead is still foggy.
All right, Lao Guo, have a popsicle to cool off. Forget it. I will keep the Nobel Prize for you.

In fact, it has been made clear for a long time, but if the real inertial force cannot be quantified, it is somewhat different from Einstein's general theory of relativity. Under the glory of this great god, many positive solutions are difficult to popularize. Now, satellites specially designed for crustal movement and groundwater flow have been made by gravity, which shows that the nature of gravity has been well understood. Can it be understood that gravity and inertia force are equivalent? In other words, the inertial force produced by a black hole or a big bang is completely equivalent to the gravitational force produced by combining into a planet. The real explanation of gravity is very different from general relativity. Cupid's explanation is that space is uneven and matter distorts space. The gravitational field equation refers to the gravitational properties of matter in the geometric form deduced from Newton's gravitational constant. After decades of hard work, Cupid has worked out an equation, and the error in calculating the movement of stars is very small. So everyone acquiesced and it was hard to be overthrown. If you want to overthrow it, you have to come up with a more accurate one, or no one will bother you. The gravitational field equation is the gravitational expression in the geometric state of matter. To overthrow it, we need not only high mathematical knowledge, but also a lot of physical knowledge. Good luck!
This is my theory of gravity. You are a university teacher. Please refer to/page/oxx _ wthydxknsbytp2xcw6vw0? source = omapp & ampappbar=omapp
Thank you, Sanyou, Ma Chi. My view is quite different from the mainstream view. If you can't spray, try to put up with it. Thank you.
Inertia force is usually considered as an imaginary force. For example, when you are pushed standing, because you are standing still, the pusher feels that there is a resistance to stop him from pushing you. This stopping action is considered as inertial force. This is a general explanation in all physics (books) at present, and there is no further explanation.
In fact, the topic raises a very deep and simple question, and I am willing to try it.
To understand inertia and inertial force, the key is to understand the formation mechanism of "force".
Force is a good physical quantity, but unfortunately, it is confused by the "gravity" explanation of general relativity, which leads people to fail to deeply understand why gravitational mass equals inertial mass.
However, Einstein put forward the great mass-energy equation E = MC 2. It is clearly pointed out that mass comes from energy and can be converted into energy. When considering force, mass and energy closely, I creatively put forward that "force is the product of mass-energy conversion" Mass-energy conversion needs a mediator, which is a kind of "chemostat" particle proposed in negative space theory.
Energy will not be transformed into mass spontaneously, but only with the help of mediator "chemical attractor" can energy be transformed into mass. In the process of mass-energy conversion, "force" will accompany it, which is the profound source of all "force"
All objects exist in the universe and are always in the process of constant mass-energy conversion, thus forming their own gravitational field, electric field, magnetic field and other energy fields.
When the environmental state of an object changes, such as being accelerated, the equilibrium environment of mass-energy conversion is destroyed, resulting in unbalanced force, the so-called inertial force. The greater the mass, the greater the unbalance change, the greater the inertia force and inertia, or the greater the required force, while the smaller the mass, the smaller the unbalance change, the smaller the inertia and the smaller the required force.
Negative space theory puts forward that mass comes from the transformation of mass and energy under the action of chemical molecules. Negative space theory also puts forward a theoretical prediction that can be verified by experiments:
1, there are black holes everywhere in the universe (it has been preliminarily confirmed that there are hundreds of millions of black holes in the Milky Way);
2. It is reasonable to have tens of billions of times the mass of the sun in the universe, which is very different from other black hole formation theories.
3. There are still hungry black holes in the universe, or the black hole mass does not match the horizon radius, that is, the black hole mass is light and the horizon radius is large.
4. A pair of high-energy photons will not produce positive and negative electrons when they collide.
5. Photons will not wind around the nucleus to form a so-called photon cloud, because there is no static mass and no "chemical" medium, so there is no "binding force".
6. In the end, it will prove that the Higgs mechanism is not established, and the discovered Higgs particle is just a new particle or a new combined particle.
Generally speaking, the inertia force is very clear, which is Newton's second law. When the speed changes, it is accompanied by acceleration, and when there is acceleration, it is powerful. The force acting on the object produces acceleration, and the object exerts inertial force on the outside. A deeper understanding depends on a new understanding of quality.
From one-dimensional to two-dimensional intersection, from two-dimensional to three-dimensional intersection, from three-dimensional to the starting point of black hole free fall, average acceleration force.
Inertia is that an object stays still or moves at a constant speed after losing external force, which has been concluded in physics.
Inertia is not a force, and force can change the motion state of an object. Inertia means that when an object is not affected by external forces, its motion state will not change. From the negative point of view, the function of force is expounded. Objects with power change their motion state, while objects without power do not change their motion state.
