I really enjoyed this blog post from the National Geographic mag about antipodes – polar opposite spots in the world. That childish (and not so childish) idea that if we dug a hole where would we end up on the other side of the world.
There is a map of Antipodes – places on exact opposite sides of the globe – on the site and it shows that, say if we were in Chile, digging through we would emerge in China.
It seems clear enough that, due to the fact that the Earth, and particularly the Southern Hemisphere’s majority of territory is covered by oceans, anyone connecting antipodes from the the Northern Hemisphere would hit the water on the other side.
It’s fun contemplating where the antipodes of certain spots are, try your luck: Paris? Tokyo? Auckland?
