Flat Earth Theory is the belief that the Earth is flat rather than an oblate spheroid, as supported by scientific evidence. Proponents argue that the horizon appears flat and that water surfaces are level, claiming that this contradicts the idea of a round Earth. They often rely on personal observations and interpretations of various phenomena to support their views. Despite overwhelming scientific consensus and evidence from fields like astronomy, geology, and physics, Flat Earth Theory has gained a following, particularly on social media. Many adherents question the credibility of NASA and other scientific organizations, believing that information about the Earth's shape is part of a larger conspiracy.
