They tried - there is that bore hole in Russia that goes down 12km or something.
At that depth the rock has the consistency of play dough apparently so they couldn't go any further.
Hole looks to only be 8 or 10 inches in diameter as well.
We know more about the far reaches of space than what is below our feet - ironic isn't it?
