rdinates are to be understood as coordinate ambiguities rather than physical non-localities. In section 4 this view is supported by an anal- ysis of Einstein's procedure for the synchronization of moving clocks, applied to sc-Minkowksi spacetime.

A Relationship to other approaches In this appendix I would like to contrast the results we have found to hold for tc-Minkowski spac

icular local event in spacetime appears to be observer dependent. This challenges the basic operational definition of a spacetime event proposed by Einstein, according to which an event is defined by the coincide of several particles in space and time. From the point of view just mentioned, it is not su
