The document discusses the Flat Earth Theory and the Flat Earth Society. It describes how the Flat Earth Society was founded in 1956 by Samuel Shenton but lost members after Sputnik was launched in 1957. It regained popularity in the 1990s on the internet. It notes that 1 in 50 Americans currently believe or question that the earth is round. The document outlines some of the beliefs of flat earthers and provides evidence for why we know the earth is round, including scientific experiments and observations.
