without dealing with temperature issues, gasses, lava, etc. (Remember, it is a question about gravity) If you were able to drop a golf ball down the hole, wouldn't the gravitational pull force it to speed to the center of the earth then pass the center, slow up, eventually return to the center,and float in the center point, or what? Does my description make sense and what do you think would happen? I'm no rocket scientist but this is a question I've been pondering for awhile.

Suppose there is an object on top of a smooth surface (frictional force=0). If we give the object a horizontal push, it would normally move forward. But according to Newton's Law on acton and reaction force, when I give the object a push, a force with the same magnitude but opposite direction will exert back on me, and hence the object stands motionless. Is this correct? If not, why?
