Flat Earth theory is the belief that the Earth is flat rather than a spherical shape. Proponents argue that the horizon appears flat and that images of a round Earth are fabricated. They often claim that gravity is a myth and that the Earth is a stationary plane. Supporters of this theory often rely on personal observations and interpretations of scientific data. They may question the validity of space exploration and the motives of organizations like NASA. Despite overwhelming scientific evidence supporting a spherical Earth, Flat Earth theory continues to attract a small group of followers.
