FE or RE?

Quote from: "(S)aint"

that doesn't make much sense

Because you're not visualizing it right.
Imagine a large pizza (preferably with mushrooms and extra chese). The place where all the slices meet (center of the pizza) is the north pole. All compasses will point to this place, so the south would be the rim.  

No matter where you stand on the pizza (not recommended until it cools down a bit) any direction straight towards the rim is south. Now, midway between the rim and the center, is what would be the equator (yes, a circle, just like on the round Earth). You with me so far?

If you start at the equator with a compass and keep moving west, the compass will always say that north is towards the center of the pizza,  so by following it you will eventually end up exactly where you started, having described a circle.

That's really all there is to it. Was that helpful?

no i get that part


i dont get t how you can only fall off by going south

Look at this map. The only way to reach the edge is by going south.

Listen... you'll have to make the intellectual effort and try to meet me halfway here. I don't know any simpler way to explain it.

Let me put it another way. Imagine you are standing on the face of a giant clock. The hands of this clock will ALWAYS be pointing south no matter what time it is, because the whole outer rim is the south. So, if you walk from the center downwards, you're walking south. If you walk from the center upwards, you're also walking south. Any direction away from the center is south. This is also true on a round earth; if you stand at the north pole, any direction you start walking in will be south.

Going back to our clock, if you continue walking in the direction any hand is pointing,  no matter if it's twelve o'clock, or six, eventually you'll reach the edge of the face of the clock... and possibly fall off.
