Abstract
Coleman and Korte have restated and defended an earlier attempt to refute the traditional thesis of the conventionality of simultaneity within special relativity. Here we argue their attempt still fails and respond to criticisms of a paper in which we addressed the inadequacies of their earlier paper. The spatial criterion they use to argue for standard synchronization throughout an inertial frame is merely a definition and provides no demonstration that a unique distant simultaneity relation exists in nature.

Ring-laser tests of fundamental physics and geophysics

TL;DR: In this article, the capability of ring-laser gyros for measurements of geodesic interest, including seismometry and earth tides, and for detection of other sources of non-reciprocal refractive indices, including axions and CP violation, are discussed.

Conventionality of synchronisation, gauge dependence and test theories of relativity

TL;DR: In this paper, a test-theory for local Lorentz invariance for a noninertial observer in a space of arbitrary curvature using differential geometric techniques and the Frenet frame is derived.

Simultaneity and test-theories of relativity

TL;DR: The Mansouri-Sexl test-theory is extended to allow arbitrary synchrony to be properly taken into account in the verification of relativistic theories and to demonstrate that there is no basis to claims that simultaneity relations are empirically definable.
