Shadows on a flat earth vs a sphere as it pertains to a sun rising or setting. Sphere - smooth light application Flat - more of an on off phenomenon. Also, why is the earth the only flat object in space? I may not always be able to tell a shape-shifting jew, but I can always observe a round object in the sky. I am also wondering where the flat electrons are....Or where the flat molecules are. Nature is pretty consistent and scales from the God particles through the galaxies and beyond.
