Flat Earth beliefs assert that the Earth is not a sphere but rather a flat, disc-shaped object. Proponents argue that evidence from personal observation, such as the horizon appearing flat and the lack of visible curvature, supports their view. They often reject scientific explanations and data from organizations like NASA. Many Flat Earth believers also claim that there is a conspiracy to hide the true nature of the Earth. They often rely on alternative interpretations of physics and astronomy, suggesting that mainstream science is misleading. This belief system has gained traction through social media and online communities.
