Why Scientists Briefly Thought the Earth Was Hollow

The video explores historical beliefs about Earth's interior, focusing on Edmund Haley's Hollow Earth theory. Although incorrect, Haley's work sparked interest in Earth science and contributed to scientific progress. He studied magnetic declination and proposed that Earth's magnetism was affected by hollow concentric shells. Modern science disproved this, revealing Earth's solid inner core and fluid outer core. Despite inaccuracies, Haley's ideas inspired further exploration and understanding of Earth's structure.
