ok, the oposite of moving +x is moving -x, right? xyz coordinates. so, if you can't move +x, reducing this to the coordinate system itself, that means that you can't move +x becuase the x dimension does not exist. therefore you can't move -x. so, in order to move +x, you must have dimension x, which means that you must be able to move -x. fyron, you still interested?

Umm... I'm not following the logic of that paragraph. If you have an xyz coordinate grid, or even an xy coordinate plane (or just a x number line), then you can move in x and -x directions. Why do you say you can't? Where do you get the x dimension does not exist? It must exist if you have xyz coordinate grid...
