You see, the basic atomic clock actually has to use gravity
to get it's most accurate reading.
They actually have a "fountain" almost like a water fountain
only it is forcing a very tiny ball or atoms upward and it has to
use gravity to return down and be counted as one second.

If you actually take the silly thing and flip it upside down,
It is as good as any pendulum clock of yesteryear.
It simply won't work right.
Isn't that funny?
Want to read about it also.

Do the cesium clocks on the GPS satellite
vehicles use a fountain?

Not sure and probably not the same,
but something in the same sort of form must be going on.
and cesium atoms are not immune to gravitational
effects so fountain or not, the atom will still be subject
to g forces.
Unless cesium is immune to g-forces like some
special alien spaceship would be.
:)

Already discussed. Time dilation appears in cases where the atoms
are moving and not moving and both are in the *same* gravitational
field, and so the "g-forces" are not responsible for the time
dilation.

Not moving (at rest)on a curved path and moving along a curved path
are a difference in g-forces.

I wasn't talking about a curved path, Spaceman. I was referring to
*straight* line motion, both under the *identical* terrestrial
gravitational field.

Now PD proves he does not understand that a truly straight line motion can
not stay in the same "terrestrial gravitational field".
A truly straight path would have to cross into higher or lower gravitational
potentials.
Sheesh



Nice try, Spaceman!
But the time dilation for *different* speeds in the same channel,
through the *identical* gravitational profile, follows the
expectations of SR. That is, you get what SR predicts for speeds of
0.5c, 0.8c, 0.9c, and 0.99c, even though they are in in the very same
beampipe through the same variation in gravitational field.
