The author considers it necessary to inform readers that the generations that will replace the current one may clarify the information given here, and perhaps clarify some provisions, which, however, are a consequence of the author’s understanding of these unshakable fundamental works. The author tried to approach as scrupulously as possible the analysis of the works “Heterogeneous Universe”, “Essence and Mind” and “Last Appeal to Humanity” and on their basis to explain natural phenomena according to the practically (experimentally) confirmed theory of heterogeneity (which, however, due to the fear of science officials and, due to political goals, is hushed up by the modern scientific community). In the book, the author shows how easily and clearly all natural phenomena are explainable from the position of the theory of heterogeneity, which allows you to abandon all theories and postulates that are not based on anything, leaving only one - the postulate of the existence of matter.
