Pulsating Universe

We live in an era of cosmological revolution. The discovery in 2015 of gravitational waves from the merging of multiple stellar-mass black holes addresses the problem of "dark matter," the existence of which could not be explained for over half... a century. This discovery led to the creation of a model of an oscillating Universe, where gravitational radiation and black holes play a key role. 
Stephen Hawking believed that nothing before the Big Bang could affect us. We believe he was mistaken: the history of the Universe before the Big Bang is crucial for our cosmological cycle, and relics of past cycles are abundantly scattered around. The main relic objects are massive black holes.
This book describes cyclic cosmology for the first time, explaining the physical mechanism of the Big Bang and the current acceleration of the Universe's expansion (the phenomenon of positive cosmological constant or "dark energy").
The popular presentation of key issues in cosmology and their resolution through the theory of the oscillating universe is accessible to the widest audience of readers interested in this topic. The appendix contains a comprehensive mathematical description of the oscillating Universe with variable gravitational mass.
