Symmes's Theory of Concentric Spheres

Symmes's Theory of Concentric Spheres is a book written by an anonymous author who refers to themselves as ""A Citizen of the United States"" and was first published in 1826. The book presents a theory that the Earth is hollow and contains a series of concentric spheres, each of which is habitable and contains its own unique ecosystem. The author argues that the Earth's poles are wide open and that one could enter the hollow interior through them. The book is divided into several sections, each of which presents evidence and arguments in support of the author's theory. The first section provides an overview of the theory and the evidence that supports it. The second section presents arguments against the prevailing scientific view of the Earth as a solid, dense sphere. The third section provides evidence from various sources, including historical accounts and geological observations, that supports the theory of concentric spheres. The fourth section of the book is devoted to the exploration of the hollow Earth, including descriptions of the various ecosystems that exist within each sphere. The author argues that the interior of the Earth is a paradise, with abundant resources and a mild climate. The final section of the book presents the author's vision for the future, in which humanity will explore and colonize the interior of the Earth.Overall, Symmes's Theory of Concentric Spheres is a fascinating and imaginative work that challenges conventional scientific views of the Earth's structure and offers a unique vision of the possibilities of human exploration and discovery. While the theory presented in the book has been largely discredited by modern science, it remains an important historical document that reflects the spirit of exploration and scientific inquiry that characterized the early 19th century.This scarce antiquarian book is a facsimile reprint of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.
