Okay, this is probably a lame question, so I’ll apologize beforehand. Nevertheless, I posted a comment to someone in the Pit that he was digging a hole so deep that he was nearing China. That got me to thinking about this question:
If we were able to dig a hole through the center of the Earth to the other side, at what point would the dirt be above us instead of below? Exactly in the middle? Would gravity pull the dirt down into the hole at that point? If we were in a hole exactly in the center of the Earth, which way would gravity pull us?
Does anyone know?
