: : : say you had an EXTREMELY dense planet, and you hollowed out a sphere in the exact center, and put a ball in the middle, could the gravity of the outside of the planet rip the ball apart into infinately many pieces? assuming the gravity on all sides of the ball was equal...

: : : is this right?

: : No, as I've said before you will be weightless everywhere in the spherical hole, not just at the center. The mass will not be torn apart.

: The hole itself is at the center, but then the object in it can be anywhere in the hole, not just at the center of the hole, and then no matter where the object is in the hole it will undergo no gravitational acceleration. For instance it is not attracted to a side wall no matter how close it gets to one.

why?
