This book dissects the popular proofs for the Earth's spherical shape, commonly found in astronomy and geography textbooks, and reveals their inherent logical flaws. The author, an astronomy enthusiast, meticulously examines arguments based on circumnavigation, the Moon's shadow during an eclipse, and other phenomena, exposing the underlying assumptions and inconsistencies. Challenging the long-held beliefs of the Copernican system, the author demonstrates that these so-called proofs fail to establish the Earth's globular shape conclusively. This critical analysis uncovers the hypothetical nature of the Earth's spherical form, a fundamental tenet of modern astronomy. By scrutinizing the validity of these proofs, the author invites readers to question established knowledge and encourages a deeper understanding of the scientific method. Thought-provoking and enlightening, this book sheds new light on the history of astronomy, the nature of scientific inquiry, and the importance of critical thinking in shaping our understanding of the world.
