north is a direction horizontally, going along, if you stretched out the earth into a flat ball and walked to the center (north) you would be walking up. if you look at he earth as if its a ball in a vacuum,we cant see outside the vacuum therefore there is not way of telling which way is up in the vacuum, and if we cant say which way up is we cant point to the top of the world, just another point on a sphere in a vacuum.
