Einstein’s physical chronogeometry

Abstract

In Einstein's physical geometry, the geometry of space and the uniformity of time are taken to be non-conventional. However, due to the stipulation of the isotropy of the one-way speed of light in the synchronization of clocks (or definition of simultaneity), as it stands, Einstein's views do not seem to apply to the whole of the Minkowski spacetime. In this work we will see how Einstein's views can be applied to the Minkowski space-time. In this way, when adopting Einstein's views, chronogeometry is a physical chronogeometry.

The Conventionality of Simultaneity and Einstein’s Conventionality of Geometry

“…19 We must notice that the conventionality of simultaneity thesis is not uncontested in the philosophy of relativity (see, e.g. Selleri, 1996;Anderson et al, 1998;Janis, 2014;Valente 2017a). It is beyond the scope of this work to address this issue here.…”
