Is it really so hard to believe that the majority of people in the world are just plain ignorant of facts which don't directly impinge upon their daily trek through the rat maze?

Its not that they're stupid or otherwise mentally deficient, its simply that those particular pieces of information are, in a practical sense, utterly irrelevant to them. They could care less about the orbit of the Earth or the orbit of an electron, its pointless data. They don't see the need to know, so there's no effort to learn it. To the average Joe/Jane on the street, knowing the first thing about the world beyond the atmosphere is nothing more than trivia at best.
