This book attempts to lay the foundation for the development of a unified field theory (or "theory of everything") based on a scientific-philosophical approach. This approach has made it possible to qualitatively describe the principles of the unified field theory. Even without quantitative analysis, this description already provides a coherent explanation for all known types of interactions. Moreover, the proposed foundations help resolve many unresolved problems in physics, such as the nature of dark energy, dark matter, empty spaces in the cosmos, galaxies without dark matter, antimatter, and other phenomena.
