Imagine two masses, at the origin and (0,1,0). They attract at certain
gravity, and have certain acceleration. Now an observer moving along
the x-axis will see a slower acceleration, since the y-distance is
invariant and time dilates. But, he measures greater masses! How can
bigger masses attract weaker?
