sigh, no need for another argument, im just saying, you..do..not..need..six...coordinates in space to locate a point... let me try and explain clearly.
In the movie, he drew a cube, on each face of the cube, he drew a dot, correct? yup!, now, from one face to the opposite face, he connected the dots! however, the way he did it, each dot was at the centre of each face, hence the lines met, now thats fine if you have six points that magically can fit onto the centre of six faces of a cube, however, if they dont, none of the lines will intersect, and you havent definied any point in 3 dimensional space!!!
Im going to go with the idea that a constellation is a point in space just for convenience sake here.
If anything, this shows the need for a frame of reference! The way he showed the six points in the movie, each point corresponding with its counterpart on the opposite face, so that the lines would intersect, he could have had the same result with 3 coordinates, if they didnt correspond, you just could not define a point in space!!! try it, draw 2 cubes, on one, draw corresponding points on opposite faces all designed so that the lines intersect at one point, and youll see you could use just 3 cartesian coordinates to define that point, now on the other, draw six dots, one on each face, in a radom spot on the face, draw a line between the opposite faces and youll see that the lines do not intersect! that is the best way i can think of putting my point across on this board!
