I should have avoided 'flow' as it seems to give different thoughts depending on ones view of it.

Flow is ok. If you think of it as variations of gravitational field the particles would tend to flow down the gradient.

Note-The better analogy would have been P-Waves .
....P.M.

P waves are longitudinal compression similar to sound waves. Remember with gravitational waves you need to think transverse-transverse quadrupole waves

I belieb ya , somebody tell Franklin!
In truth , he ain't makin' any waves !
