What are the properties of photons and electrons? What the hell do they have to do with each other?

- About "The spin directions of the two electrons must be opposite at the same time"

The fact that electrons have different spin directions is suspicious, especially for electrons orbiting the nucleus. Because it has to do with the formation of electrons. How did so many electrons form in the universe? There should be three ways. In one way, two photons with a mass equal to that of an electron each intersect at a relative speed of 300,000 kilometers per second at a certain Angle to synthesize an electron. The electrons produced in this way should be few and far between, and would only be produced in an environment like Earth with plants and clouds. So, for the vast majority of electrons that exist in the universe, they must have been created in the other two ways. One way is that the electrons are formed in the black hole by the centripetal pressure and expansion pressure of the black hole. (In the black hole, the independent hot particles are also squeezed into the two elementary particles, protons and neutrons.) Another way electrons are produced is when protons and neutrons break apart. Therefore, the vast majority of electrons in the universe should be formed in black holes. That is to say, most of the conditions for the formation of electrons are the same, so its properties should also be consistent, or the same. The spin of an electron is one of its properties. Therefore, the spin of the electron should also appear to be consistent and identical in direction, and should not be positive or negative.

"If the outermost electron gains enough energy, the electron will be freed from its nucleus and become a free electron."

It is an objective fact that the extranuclear electrons can get rid of the bondage of the nucleus and become free electrons under certain conditions. Triboelectrification is the expression of electrons escaping the bonds of atomic nuclei and becoming free electrons. But what are the conditions under which an extranuclear electron can become a free electron? It should be the expansion effect caused by the large and rapid increase of hot particles, rather than the absorbed energy of electrons. Let us take the example of triboelectricity to show how the expansion effect of a large and rapid increase in hot particles causes the extranuclear electrons to become free. To rub something is to exert a force of friction on it. This friction will destroy the electrons in the surface atoms of the object and even the protons and neutrons in the nucleus. The result of destruction is that some electrons, protons, and neutrons in the surface atoms of the object are decomposed and reduced to independent hot particles (the heat generated by friction is the manifestation of the existence of independent hot particles). The volume of electrons, protons, neutrons, which were originally dense, will expand suddenly after being decomposed into independent hot particles, and this sudden volume is a force. It is this sudden expansion force that pushes out some of the other extraneous electrons in the object being rubbed and becomes free electrons. So, instead of "the outermost electron gaining enough energy" to become a free electron, the volume of the electron, proton, and neutron after being broken down into independent hot particles suddenly expands and pushes the extranuclear electron out of the nucleus and becomes a free electron.

"The photoelectric effect does not mean that a photon can be converted into an electron, but that when an electron absorbs a photon of a certain energy, it becomes a free electron and can generate an electric current."

The photoelectric effect is definitely the corresponding conversion of photons into electrons. Of course, the conversion of particle matter such as photons into particle matter such as electrons needs to meet certain conditions. For example, it must be two particles of light with a mass equal to that of an electron to synthesize an electron. For example, two light particles whose mass is equal to that of an electron each intersect with the kinetic energy of 300,000 kilometers per second and at a certain Angle to form an electron. Biosemiconductors in plants (i.e., chloroplasts) and man-made semiconductors use this mechanism to synthesize electrons from sunlight. We can also prove in reverse perspective that "the photoelectric effect does not mean that photons can be converted into electrons, but that when electrons absorb photons of a certain energy, they become free electrons, and they can generate current" is wrong. For example, if we put a solar panel and an iron plate in the same place to receive sunlight, then the electrons in them at the same time "absorb photons of a certain energy", why the temperature of the iron plate will rise sharply but not produce current, while the solar panel will produce current? This is because the iron plate does not have the conditions to convert sunlight into electrons, while the solar panel has the conditions to convert sunlight into electrons. Therefore, after the solar energy hits the iron plate with a strong kinetic energy of 300,000 kilometers per second (that is, the so-called photon that absorbs a certain energy), it is completely and completely decomposed and reduced to an independent state of hot particles. Some of the sunlight enters the solar panel at a powerful kinetic energy of 300,000 kilometers per second, and is converted into electrons by artificial semiconductors and forms an electric current. Therefore, photons can be converted into electrons and form an electric current. Instead, electrons become free electrons when they absorb photons of a certain energy.
