In the One-Way Linear Effect, the round-trip time interval T0′ taken by light to propagate around a moving linear closed contour, is measured by a device. If the contour changes velocity by Δv, the round-trip interval T′(X′,Δv) turns out to d

We show that the one-way speed of light, along an open contour AB on the uniformly rotating Earth, is observable. Our approach exploits the property of the Sagnac effect that can measure the Earth's local angular velocity and, correspondingly, the pe

Las ecuaciones de Proca prevén la posibilidad de una masa no nula del fotón. En este contexto de la electrodinámica de rango finito, los enfoques utilizados para determinar la masa del fotón, o sus límites superiores, están basados tradicionalm

We consider an example of a moving closed contour and the role played by simultaneity in the description of light propagation on the contour's moving sections. We show that, when constrained to propagate along the contour, the local speed of light on

We investigate rigorously the behaviour of light propagation in the closed contour of the linear Sagnac effect. Assuming that the local light speed is c in a section of the contour, our approach ma...

We consider a thought experiment, equivalent to the Sagnac effect, where a light signal performs a round trip over a closed path. If special relativity (SR) adopts Einstein synchronization, the result of the experiment shows that the local light spee

We thoroughly examine the role of absolute and relative simultaneity in the interpretation of the Sagnac effect, using an approach that allows for determining the local speed along the light path. If the local speed of light is assumed to be c over t
