Annotation
The newest cosmological revolution began in 2015, when gravitational waves were discovered from the merger of many invisible black holes of stellar masses that make up the dark matter of the cosmos. This discovery led to the creation of a model of an oscillating universe, in the dynamics of which gravitational radiation and black holes play a key role. This book is the first to describe cyclic cosmology, explaining the physical mechanism of the Big Bang and the modern acceleration of the expansion of the Universe (the phenomenon of the positive cosmological constant or "dark energy"). The main text of the book is written in popular level, but the application contains an exhaustive mathematical description of an oscillating universe with variable gravitational mass. The book is of interest to a wide range of readers, physics students and specialists.
