Elements of Modern Cosmology and Bran Theory . The textbook, published by the team of authors, is a fascinating and deep immersion into the world of modern cosmological theories and concepts that shape our understanding of the universe. This manual will be an indispensable resource for students studying physics and astronomy, as well as for anyone interested in the latest achievements in the field of cosmology and theoretical physics. From the first pages of the reader captures not only the scientific approach, but also a fascinating style of presentation. The authors, with extensive experience in their fields, share knowledge about modern cosmological models, including the theory of brane, which is one of the most relevant and discussed topics in physics. This theory suggests that our universe may be only one of many existing in a multidimensional space, which opens up new horizons for understanding the nature of reality. The book covers a wide range of topics, ranging from the basics of cosmology to complex concepts such as dark matter and dark energy, which make up most of our universe but remain poorly understood. Readers will be able to learn about how current technologies and observations, such as space telescopes and gravitational wave detectors, help scientists test and develop these theories. In this context, the authors not only explain complex scientific concepts, but also emphasize the importance of an interdisciplinary approach that integrates physics, mathematics and philosophy. This book will be especially interesting for senior students, graduate students and teachers, as well as all science lovers who want to deepen their knowledge of space. It can be an excellent addition to courses in physics, astronomy and even the philosophy of science. Readers who are already familiar with works such as Stephen Hawking's A Brief History of Time or Brian Green's Elegant Universe will find in this tutorial not only new ideas, but also an opportunity to understand more deeply the already known concepts. The style of the authors is distinguished by clarity and accessibility, which allows even complex topics to be presented in an understandable and fascinating form. This makes the book ideal for those who are just beginning their acquaintance with cosmology, as well as for those who already have certain knowledge and want to expand their horizons. Each section of the book is logically structured and contains many illustrations, graphs and examples, which contributes to better assimilation of material. The topics raised in the book go beyond purely scientific questions. The authors touch upon philosophical aspects of cosmology, such as man's place in the universe and the nature of time and space. This makes the book not only a textbook, but also a real source of inspiration for thinking about our existence and how we perceive the world around us. Elements of Modern Cosmology and Bran Theory . The textbook is not just a book, but a whole world of knowledge that is waiting to be opened. It will be a reliable companion for all who seek to understand the complex and exciting aspects of our Universe, and will help readers see how science and philosophy can intersect in search of answers to the deepest questions about our existence.
