Default GPS CLOCK PARADOX

According to relativists, GPS clocks GAIN 38us per day on the ground clock.
That is due to two components, 45us for gravity and -7us for relative speed.

Accordingly, an observer (OO) in GPS orbit would see the GC LOSING 52us per
day.

After one year, the OO would calculate that the OC was about 19ms ahead of the
GC.
However, the GO would calculate that his GC was only 13ms behind.

What happens when the clocks are reunited?
Who is right?

They both are right for their own different journeys thru spacetime.

Just as in the so-called twins paradox .. both twins watches are correct for
the relevant twin. One twin really is older than the other.

Two people drive different routes from city A to
city B. When they are reunited, one odometer reads
220 km and the other reads 230 km. Which one is
right?

Only when the result is taylor expanded can this identification be
made. This has been explained to you before.

Really, Ralph? Why don't you show us your calculations that show us
how you got both numbers.

You wouldn't be making an argument about something you couldn't
calculate, would you?

According to relativity, both odometer readings are wrong. They do
not represent the true distance of the routes travelled because of the
length contraction effect.
According to Newton's law, both odometer readings are right.

The GPS clock paradox is a variation of the twin paradox, so no valid
solution.

It was an anlogy only .. derr .. to illustrate that taking different paths
in space gives you different elapsed distances .. and that similarly
different paths in space time can give you different elapsed times. And
there is no such thing as 'true distance' in any case.

According to Newton's law, both odometer readings are right.


Just as in SR, both clocks are right in the so-called twins paradox. They
are simply measuring different quantities.

The GPS clock paradox is a variation of the twin paradox, so no valid
solution.


Why not .. the so-called twins paradox is well explained by relativity by a
number of methods (all giving the same results) .. why do you think there is
no 'solution'? Why do you even think there is something there that needs
solving?

Is Mr. Poe really as blind as Androcles has claimed you to be?

This is a classical case of the twin's paradox if you have not
realized it finally. It is absolutely impossible to resolve because
of the mathematics of the Lorentz transform. This paradox occurs
through the very combination of time dilation due to observed (thus
relative) speed and the principle of relativity.

Did they practice 'no child left behind' nonsense as early as during
your childhood?

It doesn't need to be 'resolved' as there is no real paradox involved .. and
it is *due* to the Lorentz transforms .. they predict it. Get it right,
dumbo.

Do explain how you think the Lorentz transform is relevant to non-
local regions.
