Vacuum Quantum Electrodynamics Quantum Chromatic Dynamics Quantum Odor Dynamics, there is still some disagreement about the novel and complex nature of vacuum given by particle physics. One view is that vacuum is a special state of matter. Another view is that vacuum is a special form of matter. Although these two judgments are only one word difference, they reflect two different understandings of the concept of vacuum. First analyze the different meanings of form and state. The world around us is made up of matter, and the form of matter is diverse. The celestial quasar molecule hadron quark regulates the field gravitational field and so on are all different forms of matter. We usually say that the electromagnetic field is a special form of matter, that is, the electromagnetic field is a special kind of material. If vacuum is considered as a special form of matter, it means that vacuum is a special kind of substance. In physics, the movement of matter presents a variety of states. The way to describe different movement states is also different. Usually the movement state is simply referred to as the state. If vacuum is considered as a special state of matter, in fact, the vacuum itself is not A substance, it is only a special state of matter. Quantum Electrodynamics and Vacuum The modern vacuum theory is essentially a quantum theory. The quantum field is the basic form of matter. It is a matter object with both fluctuating and microscopic properties. It has various motion states such as excited states and ground states. The appearance of the excited state of the quantum field represents the generation of real particles. The disappearance of the excited state represents the disappearance of real particles. The disappearance of real particles only indicates that the excited state of the quantum field has disappeared, rather than the quantum field, the object itself has disappeared, and the quantum field still exists. However, at this time, the quantum field is in the lowest energy state, that is, in the ground state, and people put the ground state. The quantum field called vacuum vacuum is not empty, vacuum itself is a special kind of material, that is, the quantum field of the ground state. Therefore, vacuum is a special form of matter, not a special state of matter. Vacuum is the quantum field of the ground state. Therefore, vacuum can have various physical properties like other forms of matter. For example, vacuum zero oscillation in vacuum vacuum oscillation of quantum electrodynamics, etc., vacuum zero oscillation is the oscillation mode of the quantum field that constantly oscillates in the ground state. The vacuum fluctuation is the continuous generation of various virtual particles in the vacuum. Disappearing or interconverting, and vacuum polarization is the charging of real particles that act on the vacuum to change the charge distribution of the cloud of particles in the vacuum. If we think that vacuum is a special state of matter, that is, vacuum is just a property of matter, it is difficult to understand the physical contents of vacuum fluctuation and vacuum polarization. With regard to precise experiments in quantum electrodynamics, not only the physical effects caused by vacuum fluctuations and vacuum polarization were observed, but also the experimental values ​​obtained were in accordance with the theoretical calculation of quantum electrodynamics with very high accuracy.
