X. Everett Interpretation

The American physicist H. Everett believed that many of the difficulties of physical cognition, in particular those related to attempts to create a unified field theory, can be removed by making the maximum possible universal interpretation possible for cantilever mechanics. In this connection, he did not find another equally comprehensive concept, such as the concept of wave function. As a result, Everett came to the concept of a universal wave function. It is universal, but not homogeneous, but represents, as Everett mentor W. Wheeler claimed, relative states, i.e. many worlds. That is why De Witt proposed the term "world-wide interpretation of quantum mechanics", which became very popular.

A universal world wave function is given decisive importance in the Everett concept. There is reason to believe that to a certain extent this step was inspired by the work of J. von Neumann. He was a genius gifted mathematician, and mathematicians are known to have a tendency to universal constructions. But von Neumann, focusing on the mathematical description of quantum measurements, was guided by the Copenhagen interpretation, which implied the collapse of the wave function. And this was already unacceptable for Everett. It can not collapse what constitutes the true content of everything and everything. The main content of Everett's interpretation was as follows:

1) the universal wave function represents the entire physical universe;

2) because of its heterogeneity, expressed by the principle of superposition, it also represents individual physical worlds;

3) the latter are constituted by measurements, i.e. the choice is made by the people themselves;

4) choosing this or that alternative, people do not destroy other physical worlds, the reality of which is manifested in interference patterns.

It should be noted that, up to the obvious successes of the theory of decoherence, which followed only after 1982, Everett's interpretation met with a cool reception. Offended by this, he generally abandoned theoretical physics. But the theory of coherence returned interest in the concept of Everett. After all, this theory is a proof of the quantum nature of all experimentally attainable physical states. It is no exaggeration to say that the theory of decoherence was a continuation of Everett's efforts to give the wave function of universal significance. Nevertheless, even today, the many-world interpretation of quantum mechanics raises objections. Here are some of them.

First, there is no decisive experiment that would prove the truth of the multi-world interpretation. Secondly, the reality of many worlds has not been proved, for there is no clear mechanism of interaction between them. Thirdly, the world is multiplied beyond measure. One should remember the Occam razor: do not multiply unnecessarily the number of existing. Fourth, many important physical phenomena, for example, gravitational phenomena, are not taken into account. Fifthly, the mechanism for choosing alternatives is not explained. Sixthly, it is not clear how a person behaves rationally in a world saturated with numerous alternatives.

In the opinion of the author, one should not demand from the multi-world interpretation more than what it can give. Everett believed that his interpretation was of a meta-scientific nature. All other interpretations are less thorough. In fact, in every interpretation there are strengths and weaknesses. All of them are meta-scientific. Everett was strong in emphasizing the actual significance of the wave function. But his theory lacks detail. In particular, he did not take into account that quantum mechanics is not suitable for describing quantum field representations.
