The rational world would ask: How does the velocity of propagation of
light VARY WITH POSITION? Increases and becomes greater than c=300000
km/s? Decreases? Increase and decrease depend on what?

The rational answer is as Einstein explained in 1916:
Light speed depends on the gravitational potential and decreases with
decreasing gravitational potential, which results in Huygens light bending.
Clock rate decreases similarly with decreasing gravitational potential,
while horizontal lengths are unaffected in GRT. In that way, locally the
quotient dx/dt=c.

Against what do you measure the clock to determine that
it has decreased?

Why don't all clocks respond the same to changes in
altitude?

I don't understand that very well: as a massy object approaches c,
force applied does not increase the velocity delta F = m delta v,
instead it increases mass and velocity, delta F = delta m delta v. As
v approaches c, delta F = delta m v. At even small values of v the
coefficient of m is not unity. How do you talk about the tradeoff
between those two, mass and velocity, relativistically?

So, any mass under acceleration gains mass, because F = ma and c is the
speed of light?

Then, if you have a ring cyclotron on a barge, and you can recover the
energy from accelerating particles by slowing them with 100%
efficiency, can't that cause oscillations on the lake, yet the ring
cyclotron would be at equilibrium?

The point here I guess is that gravity is always on. Say there's a
Ferris wheel, which is a circus ride, and the cars on one side contain
accelerated gyroscopes, wouldn't gravity draw that side to the ground?
Then, if the energy is recovered and sent to the car that is now on
that side, wouldn't that contribute to spinning the Ferris wheel, or
water wheel?

Space-time is flat, the geodesics are ephemera. Gravity is always on,
why?

How do you parameterize the tradeoff? Is that an N-body problem?

I like to see that. The Eur. J. Phys of which date?

OK, S141. Right, ref.1! Thanks )

The simple (simplified) answer: against one local clock that is used as
standard. See GPS.

Why don't all clocks respond the same to changes in altitude?

Of course different clocks may be differently affected by for example
barometric pressure, and balance clocks are even affected by gravitational
field strength.

So you believe that IF clock speed is influenced by {something that
influences} light speed THEN changing the clock rate will change the speed
of light?

Wait a bit while I adjust the regulator on my pocket watch.....
Yep, in Sue's universe, it change the rate of all nearby clocks and the
speed of the passing beam of light from my laser pointer.

A new Sue'llusion. :-

I don't see that you made any type of graphical errors or such.
Just don't confuse The Lorenz Trains Forms develope by Lawrence of
Trainsylvania with the Lorentz transforms nor comb your hair with a
coolcomb and you should be ok.
