A Reparation, Universal Gravitation a Universal Fake, The Earth an Outstretched Plane, Sun, Moon and Stars Small Bodies Near the Earth, Astronomical, Scientific and Biblical Evidence – DeFord, C. S. (PDF)
A Reparation: Universal Gravitation, a Universal Fake, written by C.S. DeFord (Charles Sylvester DeFord, 1860–1954), is a work of early 20th-century flat-earth literature. The 62-page book presents a "reparation" against modern scientific understanding by arguing that the earth is a stationary, flat plane and that Newton's theory of gravity is a total fabrication.
