Abstract

In this report a history of the emergence of various concepts of possible worlds that have entered science in different ways - as discovery in quantum mechanics, as well as in the course of solving semantic problems in mathematical logic, or through the desire of mathematicians to introduce into physics a categorical apparatus that is alternative to the apparatus based on set theory is provided. According to the author, the criterion of the reality of possible worlds in theoretical terms may be the development of the same physics applied to them as in the case of theoretical physics known to us, the progenitors of which were Newton and Leibniz.
