Flat Earth

The notion of a flat Earth is the idea that the inhabited surface of Earth is flat, rather than a curved spherical Earth. This idea has been roundly disproved for many centuries, and the term "flat earther" is sometimes used colloquially to describe those who cling to discredited ideas.

This article focuses primarily on the views about the shape of the earth during the history of Europe, on historical evidence for and against the modern belief that people in Medieval Europe believed that the Earth was flat, on modern believers in a Flat Earth, and on the use of the idea of a Flat Earth in literature and popular culture.
