the idea of falling in natural human language(s) as falling down begs the definition of what down really is. what is down in natural human language(s)? down may be straight towards your feet, or if you are on a hill, be off at an angle. often an attempt is made to correct this definition by saying down is towards the center of the earth. but that definition only works here on earth. the idea of falling using common everyday language as being in the direction of down does not work in places in the universe other than earth. in space, somewhere between the earth and it's moon, an object may fall to the earth or fall to the moon. at other places an object may fall towards the sun or jupiter. at other places in the universe an object may even fall to a point in space between stars and planets.
