The book tells about the development of ideas about gravity throughout the history of science. In the description of the current state of gravitational theory, the main attention is paid to the general theory of relativity, but other theories are also discussed. The formation and structure of black holes, the generation and prospects for detecting gravitational waves, the evolution of the Universe, starting with the Big Bang and ending with the modern era and possible future scenarios, are discussed. Options for the development of gravitational science, both theoretical and observational, are presented.
