Two clocks at different frames runs at different rates. Why? Because a
clock second will contain a different amount of absolute time in
different frames. Therefore there is no such thing as synchronizing two
relative clocks. The events remains synchronized for the two observers
becasue the two different clock readings represents the same amount of
absolute time.

What are "relative clocks"?

What procedure would you use to synchronize two spatially separated,
relatively stationary clocks?

PD

Relative clocks means two clocks in relative motion.
The only valid way to synchronize two clocks in your frame is to
synchronize them while they are touching. Then slow clock transport
them in the opposite directions at the same velocity and stop them at
equal distance from the point of synchronization. BTW, SR agrees such a
pair of clocks will remain synchronized.
Using light signals to synchronize two spatially separated clocks is a
bogus and circular procedure.

Wormy is a runt of the SR experts.

How do you know that they will remain synchronized? How would you
*check* that? Or are you just going to assume it?

Because SR and all ether theories say so.

Once any two clocks are in different inertial frames having
relative motion, they can no longer said to be synchronous for
most observers, as time and space are effected by relative motion
and gravitation.

The equations of SR and GTR model these effects well and are
empirically correct. Furthermore, radio signals *are* used to
synchronize spatially separated clocks and is done in every GPS
receiver.

Actually Einstein's exposition of SR provides a way to check it. Do you
remember what that is?

Agree.

Ken:
The purpose of the SR/GR equations is to calculate the clock time
interval for a specfic interval of absolute time in the observer's
frame. So what is your point????
