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.

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. Aug 28, 2011 at 0:20

    Are there actually any 'round earth' mods?

    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. Aug 28, 2011 at 19:12

    @Diskilla - There used to be. They've since been removed. Jan 16, 2012 at 15:33
