Is the earth actually flat? ?
Flat Earth theorists believe earth is shaped like a disc, with NASA workers guarding the sides to prevent people falling off.
Some also claim NASA fakes pictures of the globe, in an effort to keep the truth from the public.
Astronaut Commander Terry Virts spent 200 days on the International Space Station and says the Earth is most definitely round.
But Flat Earther Mark Sargent strongly disagrees saying the 'earth is not spherical'.
