Zero gravity
 
Hi Igor,

Actually, that's not such a stupid statement. It can be shown that in a
hollowed out sphere, or even one solid all the way through, the
gravitational acceleration vectors due to the mass itself which are "to the
left" cancel the acceleration vectors "to the right" and at the center of
mass, the total acceleration vector has a zero length, i.e., "gravity goes
zero at the center of mass."
