Criticism of solipsism in the contexts of many-world models

The article analyzes the problem of the relationship between consciousness and physical reality in the context of some multi-world models. It is shown that the adoption of many- worlds models imposes certain restrictions on the criteria of scientific theory, as well as on the concept of what is considered a “theory of everything”. Based on the original criticism of solipsism and the properties of the second law of thermodynamics, it is proved that consciousness can be considered as a derivative of the fundamental principles (laws of nature) of the physical reality in which it operates. From this follows the conclusion, considering the adoption of the many-worlds hypothesis, that different types of consciousness should correspond to different worlds (with different sets of basic principles). Conclusions are also made about the role and status of mathematics in the considered hypothetical conditions, and the possibility of creating a “theory of everything” is questioned.
