Is clock synchronization compulsory

I doubt I’ll convince you, as you are an old fox set in your relativistic ways. But your posts are interesting and warrant courteous reply.

In response to whether you can derive the relativistic Doppler equation without using Lorentz Transformations, and without need of Einstein’s clock synchronization.
The answer is yes.
See equation set 9.6 and 9.7

This is just an old and tired crank theory,well known over the internet, we do not discuss crank theories in this forum.

The general Doppler equation (9.6) includes arbitrary angles for both source and observer with respect to ether. Clocks are initialized at origin t’= t=0, and thereafter do not need synchronizing.
The equation set produces a match for the relativity’s velocity addition formulae only if the observer and source angles are zero.

The equation set (9.7) matches relativity’s Doppler equation for an arbitrary angle when the observer’s speed through the ether is zero.

Regardless of whether you support ether concept, it’s fascinating that the derived general Doppler equation can mirror relativity this way.

Thank you for your message. I respect all my coleagues and my contact with "etherits" (in the history of my country "etherits' were the members of a social mouvement") convinced me that theirs results and those obtained by Einstein, are the same. It is importamt to underline that in the case of the Doppler Effect both theories lead compulsory to the same results because it does not involve clock synchronization. I think the same situation is compulsory in the case of the aberration of light effect. I am shure that the link you gave me will confirm that fact.
I have seen a very interesting "etherist" approach to the Doppler effect presented by Selleri showing that the formula he obtains and that obtained by Einstein are the same. Asking him why not to make use of Ockhams razor, using the simplest theory, he told me that there is place for everibody.
All the best.
