A spherically symmetric body affects external objects gravitationally as though all of its mass were concentrated at a point at its center. Is this true and can someone explain this? For example, wouldn't Earth as a black hole attract the moon with slightly more force because it's volume is condensed? Doesn't the outer portion of the Earth produce a gravitational field line not parallel to the line between the centers of the moon and Earth thus canceling the the perpendicular components of the gravitation forces?
