A Journey to the Earth's Interior: An Illustrated Hollow Earth Theory Work, First Published 1913: A Hollow Earth Theory Work, First Published 1913

By Marshall Gardner

"The earth is not solid-it is hollow, and within it exists another world." - Marshall B. Gardner

Includes the original illustrations.

First published in 1913 (and expanded in 1920), A Journey to the Earth's Interior is Marshall B. Gardner's remarkable contribution to the literature of speculative science and hollow earth theory. Arguing against conventional geology and astronomy, Gardner presents the bold claim that the Earth is hollow, with vast interior lands and even a hidden sun at its center.

Drawing upon polar exploration, unusual geographic phenomena, and reports of mysterious warm currents and migrating wildlife, Gardner contends that the hollow earth is accessible through openings at the poles. Blending imaginative speculation with references to contemporary science, his work remains one of the classic texts of alternative scientific thought in the early twentieth century.

Though rejected by mainstream science, A Journey to the Earth's Interior continues to fascinate readers as a historical curiosity, a cornerstone of hollow earth literature, and an early example of alternative cosmology. For students of pseudoscience, speculative history, and the cultural history of exploration, Gardner's book offers a vivid glimpse into the power of human imagination to challenge accepted knowledge.
