As is well known, special theory of relativity rests on two postulates: (1) the postulate of “relativity”; (2) the postulate of “the constancy of the speed of light in vacuum in all inertial frames”. In this theory, the second postulate is neither an obvious principle nor a logical consequence of other obvious principles. Therefore, in order to evaluate the validity of this postulate, its experimental verification is necessary. In this paper, it becomes clear that by accepting the common thesis of the conventionality of distant clocks synchronization, the experimental verification of the second postulate is not possible. However, it is shown that by conducting experiments to examine “the independence of the speed of light from the speed of its source”, the experimental refutation of the second postulate is possible. It is explained that under what conditions these experiments are crucial.

1967, “time and physical” geometry, discussion about implications of the Special Theory of Relativity (STR) for the debate between Static vs. Dynamic models of temporal reality became serious in contemporary philosophy of time. In this article, Putnam provided an argument in favor of Static model by assuming the STR. By virtue of the STR, he assumed that the relation of simultaneity between events is a non-transitive relation. For this reason, some philosophers (e.g. Bourn 2006 and Craig 2008) have tried to defend the Dynamic model through defending a privilege frame of reference (and so, a transitive relation of simultaneity) in relativistic setting. In this paper, by distinguishing between weak static model and strong static model I will try to argue that why assuming a privileged frame of reference, even if exists, could not have any advantage for advocates of the dynamic m
