Ugh, Niel deGrasse Tyson thinks that people thought 500 years ago that it was flat. The dominant medieval doctrine of scholars was that the earth is spherical.

He probably mixed that up with people thinking that Earth was the center of our galaxy.

It's a popular myth that people in the Middle Ages thought that the earth was flat. It was created in the 18th century or earlier and can be found in textbooks until the 1990s.
