I know Americans have a tendency to be a bit self-involved, but this is a bit much. According to a Gallup poll in 1999
, 18% believed that the earth was the center of the universe. On a side note, 3% said "no opinion." Those folks could not be bothered with such pedestrian quandaries.
Oh, and for those 18% who believe this, that picture is Galileo. That guy knew his shit.
