Did Phillip Dennis actually disprove the conventionality thesis (Dennis 2024)? Did he really prove at long last what physicists over the last century have been unable to do – to establish that the one-way speed of light in any given direction must be the same as the round-trip speed of light? Did he find any genuine inconsistency with the Anisotropic Synchrony Convention (ASC) and the young universe model upon which it is based? Well, no to all of the above…. We show below that when the full synchrony-independent equations are used, they do not support Dennis’s conclusion but rather the opposite. Furthermore, we will demonstrate several critical errors in Dennis’s analysis and show that several of his claims are incompatible with the physics of relativity.

We will here investigate common objections to the conventionality thesis[1] – the principle that the one-way speed of light cannot be measured but is instead stipulated.

We previously introduced this distant starlight issue and then examined potential solutions and their difficulties. We now move toward a solution to the issue. This solution is surprisingly straightforward, but will require some discussion of the nature of space and time as we now understand them. To that end, we will here investigate the concept of simultaneity and how this concept has developed over time.

Someone recently sent me an internet post of a critic who thinks he has disproved the ASC solution to the distant starlight issue. Peter offered thirteen propositions in an attempt to support his conclusion. Amazingly, not even one of them is correct. We will examine his errors here. Actually, if Peter had posed his claims as questions instead, they would have been good questions. So, hopefully my response here will help people get up to speed on this fascinating area of physics.
