The main place in the book is devoted to the physical side of the space phenomena under consideration. At the same time, it makes many numerical estimates necessary for a more complete understanding of explosions. The simple formulas used for such assessments are mostly familiar to everyone who studied physics in high school. In cases where a formula conclusion is required, it is based on simple reasoning. Although often they are not strict enough, they reflect the physical essence of the issue. The explanation of the nature of the phenomena described in the book is one of the most complex modern problems of physics. Naturally, therefore, the reading of the book, not limited to the perception of only the external side of the matter, will require from the reader a certain effort. The author hopes that for the difficulties that the reader will encounter, he will be at least partially rewarded by the magnificent picture of the grandiose processes of the life of the Universe that opened before him. According to the author, the book is available to all erudite secondary education.
