It has been said, what goes up must come down. The statement is so obvious that it strikes us as a truism, something so apparent that it’s legitimacy is self-evident. Then again, not everything is as it seems.
As an example, you may have noted earlier this month a small spacecraft named Voyager 1 departed our solar system for parts unimaginable. The promise of Star Trek is coming true, at least on a limited, unmanned basis. Be that as it may, Voyager has actually transitioned from the east coast of Florida where it last stood upon the earth, into a realm where basic concepts like up and down have no meaning at all.
