Weird,but just imagine that someone started digging the earth to its center starting from the north pole.And now he is on the other side,means in the south pole.Forget about the guy,now there is a perfect cylinder-like hole through which you can see.If an object falls from the north pole,what will happen?Would that stop reaching the center?Or some other thing will happen to it.How and why?
