In Chapter 1 the author sets forth his philosophical concept of matter, where he justifies the existence of two opposite forms (sides) of matter: positive and negative pra-matters. Chapter 2 recounts the physical theory of matter: the physical essence and nature of matter, as well as the types of fundamental components of non-free physical systems is explained. In Chapter 3 Samvel Pogosyan represents his approaches to the solution of Einstein’s Great Dream. He uncovers the physical nature of inertia, ideally flat space, its structure and regularities of its formation, as well as physical consequences. The basics of GchԱ - physical theory are developed. It is a general physical theory that describes free and non-free local (finite) physical systems and their types. A new cosmic model is created, within the framework of which the physical nature and micro-structure of Dark energy, as well as the direct physical reason of accelerated expansion of the Universe is brought to light. It is to be mentioned that many observable phenomena, which do not go into the frames of ΛСDМ — cosmic model, receive natural explanation within the GchԱ-cosmic model. Chapter 4 is devoted to Armons — fundamental components of the Metauniverse, to these peculiar "pumps", thanks to which the eternal circulation of matter takes place, providing the eternal existence of the Metauniverse. Here the author continues the development of Cosmology, setting forth his views on the structure of our Universe, evolution of Primary black holes, the Universe, D bodies, etc.
