    Say we take a look at point (0, 0, 1)) which lies on a sphere around the Origin with radius 1. 

    Now scale this point by 7 on the X-axis. Now it is point (0, 0, 7) and it’s distance to the Origin is now 7, meaning that the sphere intersects the Z-axis at (0, 0, 1/7). (Does this still make sense?)

    @spikeyxxx  Why doesn’t the sphere now intersect the z-axis at (0, 0, 1/7)? Isn’t it the point (0, 0, 1) that is scaled away from the x-axis?
