The "Flat Earth" theory posits that the Earth is not a sphere but rather a flat, disc-shaped object. Proponents of this idea often argue that visual observations and certain interpretations of scientific data support their view. They believe that the horizon appears flat and that water surfaces are level, which they claim contradicts the concept of a spherical Earth. Despite the overwhelming scientific consensus that the Earth is an oblate spheroid, the Flat Earth theory has gained a following in some communities. This movement often relies on social media and alternative explanations of gravity, space exploration, and photographic evidence to challenge established scientific understanding.
