uh oh... watch the name calling, please.

as to how gravity works....
gravity is a psuedo-force much in the same way that centrifugal force is a psuedo-force. it is caused by the temporal inertia of mass (its tendancy to remain at rest in a given moment in time) being accelerated through space-time.
the acceleration is provided by the accelerated expansion of the universe. as a body of mass exists in space, the 'outward' expansion of space tries to push the body of mass through time as well. as space expands, it encounters resistance from the temporal inertia of the body of mass resulting in a curvature of space-time around it.
other bodies of mass are not actually 'pulled' towards another body of mass, so much as space-time is expanding around them. 'realatively' speaking, the distance between the bodies of mass will become less. (of course, other factors such as total mass and velocity and trajectory influence the behaviours of the various bodies of mass which interact with each other.
