I’m Digging to China.
The question is this: If I dig a very deep hole through the earth, where will I end up??
Personally, I think there could be several answers for each one. Why? Well, for starters, I’m a scientist. Seriously, doesn’t it depend on the ANGLE at which you’re digging? That’s my personal belief, anyhow. And until someone (say, another scientist, for example) proves me wrong, I’m going with that opinion. Whatever the case, it’s fun to do!
(Thanks for the fun find, Sam!)
