well thats the whole point of it.

If you are in the inside then if you travel in one direction you will still bump into an edge. i.e you cannot travel indefinitley in one direction.

so puisher you have failed to give any reasonable explination of what happens if you travel straight up. You just dodge the question. You faux idiot trolling act is degenertaing into post a stupid comment and run away. You can do better than that!
