One of the fundamental laws of mechanics is Newton's law of action and 
reaction, usually stated as : "Whenever a body exerts a force (action) on
a 
second body, the second body exerts an equal and opposite force (reaction)

on the first body."

Suppose that a stationary mass is located in the gravitational field of 
another, distant stationary mass.The two m***** exert equal and opposite 
forces on each other. (Action and reaction)  Let us now allow one mass to 
move under the action of the field of the other mass. ut the second mass, 
being far away, does not yet "know
 that the first mass has moved. (gravity -- like light -- cannot propagate

instantaneously.) The second body continues to experience the same force
as 
before.

In other words, the forces are now unequal in magnitude and direction and 
Newton's action/reaction law no longer holds! Further, this situation also

is in conflict with the very basic law of conservation of momentum.

For a detailed analysis of this, and other Newtonian flaws, please see 
Jefimenko's "Causality, Electromagnetic Induction and Gravitation" OR 
"Gravitation and Cogravitation."

BTW, Timo questioned my assertion that F = MA was also "leaky." I THOUGHT 
that the above also affected this equation. After further review... Timo's

right... so far!

I hope this helps!

BTW, yes, a glass is simultaneously 20% empty and 80% full, but entirely
too 
many people (IMNTBHO) ignore the fullness and concentrate only on the 
empitiness. And that's kinda sad!
