The hypothesis for these deeper processes is not entirely absent. People have already proposed many possibilities, but they are still not mature enough. For example, quantum properties are based on probability because they can not be seen. Probability is an abstract description of facts. There is an essential difference between probability and fact. The distribution of the impact point on the target during shooting can be described by probability, but after a gun hits the target, its probability in this position must be 100%, and the probability in other positions is zero, ie, the probability collapses. The motion of microscopic particles can not be observed in detail and can only be described by probability. Therefore, we cannot know what the microscopic particles' motion and attributes will be. If the collapse of macroscopic things could be observed, all macroscopic things would have no quantum properties. If one day our observations were fine enough, then the quantum cat's conflict would not exist.

Waves and particles are two completely different substances. Quantum mechanics tells us that matter has wave-particle duality, which makes it difficult to understand, but standing waves may help us to understand. The standing wave is a kind of wave at first, but it is fixed, like a ball, and the ball is a particle. The standing wave can behave like a particle. The condition to change from a normal wave to a particle is the phase change of the wave. As long as the phase is appropriate, the wave can become a particle. When the phase changes slightly, the particle disappears. The positive and negative particles may be annihilated in this way. One electron can pass through two gaps at the same time, because the electrons themselves are waves.

The above explanations of standing waves and probabi- lities are concrete ways to solve the contradiction of quantum mechanics. These approaches are tentative. Scien- tists have also proposed many other tentative theories. It is still unclear which of them will succeed.

Objective things are concrete, and theories are abstract. There is always an insurmountable gap between theory and facts. When the theory can successfully solve practical problems, we will ignore this difference and feel that the theory and practice are completely consistent. In fact, this is only an illusion.

The formula is an integral part of the abstract theory. The formula can describe the reality, but can the formula be transformed to describe another reality? The super- position and entanglement states of the quantum are the result after formula derivation. Is there no problem in formula derivation? Is there any conditions? Newtonian mechanics formulas are used and deduced by countless people. No problems are found, but this does not mean that it is really problem-free.

All theories are man-made hypotheses. Since it is a hypothesis, it is not the true face of the objective world but a false one. The hypothesis has been tested and we believe that it can become truth, but the problem is that truth may be overturned in the future, that is, the truth is still not true. In this sense, all truths are false. Laozi said:
