Topic about physics axioms, theory, laws etc..

Since the rest frame of Westminster Abbey is rotating, that leaves some remaining troubles with simultaneity.

No, that's not true. Simultaneous events that occur in the same place remain simultaneous with respect to all reference frames, regardless of whether they are inertial or not or whether they rotate or not.

We are not talking about events that occur in the same place. We are talking about an event occurring at Westminster Abbey (e.g. coronation) and a separate event occurring in Australia (the time there when the coronation is deemed to have taken place). Those two events are space-like separated.

We need a simultaneity convention for that. A rotating reference frame is a poor starting point for defining a simultaneity standard. A good choice would instead be an Earth-centered inertial frame.

A few recent posts about clearly non-physical things have been deleted. Thank you to those who wrote good information to correct some misconceptions.

Please remember, the topic of this thread is about axioms in physics. Relativity discussions belong in the relativity forum.

I think a point that may be relevant here is that Mathematics isn't bound by Physical reality, as the Banach-Tarski Paradox whereby we can turn a ball B with volume V into two such balls with volume V each , through (relatively straighforward -- Mathematically) transformations, shows ; something that cannot be implemented physically.
