If I had a very long stretch of powered rail going in one direction, would I be able to eventually circumnavigate the planet? and if so, how long would it take?

(Assume the track is entirely flat and I burrow through all mountains I hit)

I think you may want to add a few more very's. – Wipqozn Aug 28 '11 at 1:19

Minecraft subscribes to the "Flat Earth" theory. Discounting mods, you can never circumnavigate the planet, as the "planet" will simply expand longer and longer in whichever direction you travel.

Well, there must be a edge, I mean I am pretty sure Notch is not using arbitrary precision numbers, eventually it must overflow. – Scott Chamberlain Aug 28 '11 at 0:20

Are there actually any 'round earth' mods? – fredley Aug 28 '11 at 13:36

It doesn't overflow in a simple way such that you'll suddenly find yourself at the "other side" of the flat map. Various Minecraft internals using different precisions start behaving badly and make the game unplayably slow long before any of them overflow. – SevenSidedDie Aug 28 '11 at 19:12

@Diskilla - There used to be. They've since been removed. – Raven Dreamer♦ Jan 16 '12 at 15:33
