I am new the to the flat earth society and I read all of the FAQs and pretty much everything else on this website because I have decided to write an informative speech on the flat earth theory. but, I still have some questions- like what is the shape of the earth in a 3-D model? does it look like a coin? does it look like a cone? I know the earth is traveling on an infinite plane, but is the earth itself a plane? if it has an underside, what does it look like and is it possible to go there? please help I am confused!! thank you!
