minecraft worlds on PE are finite, and the water beyond that is infinite.

If you mean the box you purchase it in, there is no box, you can only buy it from minecraft.net, and if you mean crafting a box in minecraft, it can be as big as you want, there is no determined size of a box in the minecraft community
Yes there is such thing as the Ether World in Minecraft.
since 1.8, notch has implemented a new terrain generator that simplifies world generation. the world is infinite and dependent on your cpu's capacity to store info & how much of that is deticated to minecraft. essentially, until mc runs out of space, the world is infinite. so are your creations. the sky is the limit my friend.
An underwater world seed for Minecraft is used to open an underwater world to play the game in.

No, there is no website that shows you a map of your Minecraft world. The only way to see a map of your world is by crafting a map in-game. Of course the maps your craft are only so big, and you could go though quite a few of them before you obtain enough to see a significant amount of your world.
Yes, Minecraft is global.
