Flat Earth movement

The Flat Earth movement is a belief that the Earth is not a sphere but rather flat, often envisioning it as a disc. Proponents argue that scientific evidence supporting a round Earth is flawed or fabricated, and they rely on alternative interpretations of visual observations, such as horizon behavior and perceived flatness. Mainstream science confirms Earth’s round shape through satellite imagery, physics, and astronomy. The movement persists largely as a challenge to scientific authority or as a social phenomenon, but the overwhelming consensus remains that Earth is an oblate spheroid.
