First edition, updated in 2014, 2015. The book presents a variant of the unified physical theory, the theory of everything. This theory was constructed from the ground up on the basis of a unique ratio of the primary notions: n-dimensional space, energy, length and velocity of objects. A system of equations of the primary notions was introduced in the first part of the book, and it was further developed in the second part. In the third part, this system was applied to describe the known physical phenomena. The presented interpretations of the physical phenomena can be read in the first place to understand the pros and cons of the proposed logical framework. Predictions of the theory, beyond modern physics, are collected in the fourth part of book. The last part of the book contains the descriptions of experiments that can be conducted to verify the presented theory.
