This was written in response to a preprint by Stefano Quattrini from March 18, 2018. For reference, the preprint is attached with my answer. In the meantime, Quattrini has changed his preprint, but I think that my criticism extends to the new version as well. At least, the consistent description given in my essay can be used to refute Quattrini's new attempt at showing a failure of special relativity . In BreakingtheLorentzinvariance.pdf, Quattrini proposes a scenario based on an old paper by Boughn about the "equally accelerated twins" (Reference in accel_twins.pdf) that in his belief would break Lorentz invariance, hence disprove special relativity. He is in error and this error is largely due to a lack of understanding of the original Boughn scenario. In my answer, given in file accel_twins.pdf, I first give a detailed account of the Boughn scenario to set the stage on which Quattrini plans his scenario. In particular, I show how everything follows nicely from special relativity essentially without equations, just using Minkowski diagrams. I then discuss some errors made by Quattrini and finish by concluding that Lorentz invariance has not been touched by his scenario.
