Not only do no serious, intellectually honest people currently believe the Earth is flat; the fact is this was never a widespread belief, at least in the way that you may have heard. Even astrophysicist Neil deGrasse Tyson may have gotten things a bit wrong—sacrilege, I know—when he tweeted that B.o.B was “five centuries regressed in [his] reasoning.” In reality, knowledge that the Earth is spherical is much older than that, and hasn’t been seriously questioned by more than a few wingnuts in the last two millennia.
