Have you been reading Tim and Amy’s blog (a misnomer if ever I’ve heard one… Tim has posted once). It’s pretty awesome. Like this post with a little map tool that lets you figure out where you’d end up if you were to drill a hole right through the earth.
If you were to do that, and you dropped a rock down the hole – would it get stuck in the middle or shoot out the other side? Ignoring all the effects that lava might have on the composition of the rock…
Here’s where you’d end up if you lived in Townsville. Somewhere off the coast of Mauritius.
