Reminds me of when I wondered about digging to the other side of the earth. Hypothetically, if the world were full of nothing but dirt and you could safely dig all the way through, would you feel a gradual shift from digging down to digging up or would it be sudden? The more I think about it, I think gravity would make it impossible to dig through the middle because it would be sucking the dirt in to a very dense ball. But I am no scientist
It’s weird, because gravity declines as you dig, so you would feel weightless at the center. But past the center, yes, you’d be digging “up”, and the dirt you dig would fall past you toward the center, the gravity pulling you down stronger as you neared the surface.
In any case, you’d need a way to remove dirt from the hole however deep you are.
If you wear a good pair of boots and a hard hat (safety first), you can just let the hole fill up behind you. You’re headed for the surface again, after all.
Just be sure to bring enough snacks for the trip.
