How the universe works. Introduction to modern cosmology

This book is dedicated to cosmology - a science that has recently celebrated its century. She explains why we are sure that the Universe has a beginning, where and when a big explosion occurred, which means the run -up of the galaxies, how everything that surrounds us, from atoms to galaxies, what is the future of the universe, whether worlds with other physical laws exist, What are black holes and much more. It is described in detail about what we know and that it is not known about two mysterious entities, which together make up more than 95% of the contents of the universe - dark matter and dark energy. In addition, the physical foundations of the general theory of relativity and the effects predicted.
The book is focused on a wide range of readers, but some of its sections, which set out the elements of a non -navigature of cosmology, require knowledge of mathematics at the level of initial courses of the university. This part can be considered as a kind of textbook in which the main cosmological solutions were obtained without the use of the mathematical apparatus of the general theory of relativity
