The Symmes Theory of Concentric Spheres: Exploring the Hollow Earth Theory and Its Open Poles
Introduction: The Allure of the Hollow Earth
Throughout history, the idea that Earth might be hollow and habitable within has captured imaginations around the world. One of the most intriguing theories regarding this idea was proposed by John Cleves Symmes, an American army officer and adventurer who put forth the "Symmes Theory" in the early 19th century. Symmes claimed that Earth consisted of a series of concentric spheres, creating vast, habitable spaces within, and that the planet was open at the poles. While his ideas were dismissed by the scientific community, they became a phenomenon of public fascination, inspiring expeditions, books, and countless debates.
