Atomic clocks out of sync?

Relativity is discussed in Chapter 7 of the TEW book. Currently the Theory of Elmentary Waves only deals with Special Relativity issues - not General Relativity.

Atomic clocks out of sync?

Dr Little states on page 81 of his book (The Theory of Elementary Waves) that "Clocks do not actually slow down when they move; they merely appear to slow down."

My understanding was that a moving atomic clock falls out of sync with a ground-based one and that if the moving clock is returned to earth and set next to the ground-based one, the two clocks will still be out of sync.

This sounds like a "real" effect and not just a visual one.

Lewis Little replied to this question by email. I reproduce his reply here:
In the book I have considered only the special theory of relativity. The special theory predicts no change to the actual rate of clocks.

The general theory [of relativity] does predict a change, and this is what is alleged to be observed in the experiments you mention. I say "alleged" because I have not as yet worked out the TEW picture of gravity/general relativity.

However, given the fact that gravity is a real physical effect, not merely the result of a change to one's frame of reference, a change to the rate of clocks would not necessarily be unexpected.


In my own follow-up question I asked Dr Little: What if there were two atomic clocks, stationary to each other and synchronized. Now one clock flies off, moves in a circle, and again meets up in the same spot with the other clock?

Dr Little explained to me (on the phone) that, as this scenario involves acceleration (rather than steady speed/velocity), it would also be part of a General Theory of Relativity explanation - rather than a Special Theory of Relativity explanation - and his comment (above) applies.
