Re: "Unified Revolution" new book by Espen Haug

work done together with Italian physicists Gianfranco Spavieri just got published in physics essay.

Why the Sagnac effect favors absolute over relative simultaneity, Vol 32. Physics Essay.

"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 speed cannot be c in every section of the closed path. No inconsistencies are found when adopting absolute synchronization. Since Einstein and absolute synchronizations can be discriminated, the conventionality of the one-way speed of light holds no longer. Thus, as sustained by specialists, it might be a viable formulation of SR that reinstates the conservation of simultaneity, even though it allows for relativistic effects, such as time dilation. Such an approach may lead to the discovery of new effects and a better understanding of relativistic theories."


Nous considérons une expérience de pensée, équivalente à l’effet Sagnac, dans laquelle un signal lumineux effectue un aller-retour sur un chemin fermé. Si la relativité restreinte (RR) adopte la synchronisation d'Einstein, le résultat de l'expérience montre que la vitesse de la lumière locale ne peut pas être c dans chaque section du chemin fermé. Aucune incohérence n'est constatée lors de l'adoption de la synchronisation absolue. Comme Einstein et les synchronisations absolues peuvent être discriminées, la conventionalité de la vitesse de la lumière dans un sens ne tient plus. Ainsi, comme le soutiennent les spécialistes, il pourrait s’agir d’une formulation viable de la RR qui rétablisse la conservation de la simultanéité, même si elle permet des effets relativistes, tels que la dilatation du temps. Une telle approche peut conduire à la découverte de nouveaux effets et à une meilleure compréhension des théories relativistes.

This means the deeper truth likely is anisotropic one-way speed of light, and finally it looks like we have a way to check this in a Linear type Sagnac type experiment. Poincare assumed it was impossible to set up experiments to distinguish anisotropic versus isotropic one-way speed of light. It is no easy task to come up with experiments that can distinguishing between anisotropic and isotropic one-ways speed. But this should do and it must be anisotropic to be fully consistent with this Gedanken Experiment!
