About the book: 1975 / The secrets of the universe imperiously attract a person to themselves. And one of them is how the solar system and the systems of other stars originated and are developing. There were many assumptions about this. But they were all speculative.

This book describes the modern view of the origin of our world and the processes of world formation..
