The book "Gravitational constant in astronomy" by Milyukov V. K. and Sagitova M. U. It is a fascinating and in-depth study of one of the most fundamental constants in physics and astronomy. This work is not just a scientific treatise, but a real find for everyone who is interested in the cosmos, physics and the mysteries that it holds. The authors, with rich experience in astronomy and physics, offer readers a unique perspective on the role of the gravitational constant in the formation and evolution of the universe. The focus of the book is the gravitational constant, a value that seems to be only one of many constants in physics, but actually plays a key role in understanding the interactions between celestial bodies. The authors examine in detail how this constant affects the movement of planets, stars and galaxies, as well as phenomena such as black holes and cosmic expansion. The reader will be able to learn about how the gravitational constant was determined, what experiments and observations led to its establishment, and how it continues to be a subject of discussion and research in the modern scientific community. The book will be of interest not only to professional astronomers and physicists, but also to a wide range of readers, including students, graduate students and everyone who is just interested in science. If you have ever thought about how our world works, how stars and planets interact, or want to understand what is behind concepts such as dark matter and energy, then this edition will be a real discovery for you. The authors skillfully explain complex scientific ideas in simple and accessible language, which makes the material understandable even for those who do not have a special education. The topics raised in the book cover not only physics, but also the philosophical aspects of science. The authors ask questions about how our understanding of gravity has changed over time, and how new discoveries could change our perception of the universe. This work encourages the reader to think about the place of man in space and how we can use knowledge about gravity for further research and discoveries. The style of the authors is distinguished by clarity and logical presentation, which makes it easy to follow their thoughts and ideas. Milyukov V. K. and Sagittarius M. U. are known for their previous work in the field of astronomy and physics, and their experience allows them to create a high-quality and meaningful text that will be useful for both study and scientific work Their approach to the material combines rigorous scientific analysis and fascinating narrative, making the book not only useful, but also interesting. If you’re looking for literature that will help you better understand the laws of nature and their impact on our lives, the Gravitational Constant in Astronomy will be an excellent choice. This book will not only expand your knowledge of gravity, but will also inspire further research in astronomy and physics. Do not miss the opportunity to plunge into the world of space and discover its secrets with Milyukov and Sagitov.
