Symmes's Theory of Concentric Spheres is a book written by an anonymous author who refers to himself as ""A Citizen of the United States."" The book, first published in 1826, presents a controversial theory that the Earth is hollow and contains a series of concentric spheres within it. The author argues that these spheres are habitable and that there are openings at the poles that allow access to them. The book begins with an introduction that outlines the author's background and his interest in the topic. He claims to have discovered the theory of concentric spheres after many years of studying the natural world and observing the behavior of the Earth. The author then presents his theory in detail, providing evidence and arguments to support his claims. The author argues that the Earth's crust is only a few hundred miles thick and that beneath it lies a void that is filled with air and water. He claims that this void is divided into a series of concentric spheres, each with its own atmosphere, climate, and inhabitants. The author suggests that these spheres are connected by a network of tunnels and that there are openings at the poles that allow access to them. The author also addresses potential objections to his theory, such as the lack of evidence for the existence of these spheres and the difficulty of explaining certain natural phenomena. He argues that his theory can explain many of the mysteries of the Earth, such as the aurora borealis and the movement of tides. Overall, Symmes's Theory of Concentric Spheres is a fascinating and controversial work that challenges conventional ideas about the nature of the Earth. While many of the author's claims have been debunked by modern science, the book remains an important historical document that sheds light on the intellectual climate of the early 19th century.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
