Q. From a Cleveland reader: “At what point would a line from Cleveland down through the Earth's center emerge?”
A. Such locations are known as “antipodes,” or direct opposites, says University of Saskatchewan geographer Scott Bell. The word is Greek for “having feet opposite,” or people and places diametrically opposed on the globe. The most distant point on Earth from you right now is the antipode. Thus the antipodes must be separated by half the circumference of the globe (180 degrees), with one point being as far north of the equator as the other is south. Midnight at one point is noonday at the other.
