I was reading some comments from Thursday’s episode of Lost. There is a reference to Tunisia and someone pointed out that the opposite side of the earth from Tunisia is the South Pacific off the coast of New Zealand (about where the Lost island is thought to be located). They linked to this website:
So I spent a while playing around with that and learned that most places have ocean on the other side of the earth including all of the continental US, Europe, Africa, and Australia. What a boring planet. South America has an opposite in China (must be where the idea of digging a hole to China originated) and Indonesia.
