The concept of Hollow Earth suggests that the Earth is not a solid sphere but instead contains vast, empty spaces or even entire civilizations within its interior. This idea has been popularized in various myths, literature, and conspiracy theories, often depicting a world beneath the surface that is rich in resources and inhabited by unique creatures or advanced beings. While the Hollow Earth theory has captured the imagination of many, it lacks scientific evidence. Modern geology and seismology provide a clear understanding of the Earth's structure, showing that it consists of a solid crust, a viscous mantle, and a molten outer core, followed by a solid inner core, all of which contradict the notion of a hollow interior.
