Well, this week has been quite a journey. I fully appreciate that there is much discussion to be had pertaining to the outcomes of ASC, and that GR may render some of this moot. I’m just focused on the ramifications of ASC to my now refuted original posts concerning the speed of light and gravitational waves, so this thread does not get too open ended.
Norton’s article was very illuminating. The pertinent take away in the context of this discussion is that I must concede Lisle is actually representing scientific thinking faithfully as concerns the speed of light in special relativity. I’m coming around to this, but there are some consolations from the article. [I will quote for those who have not read the link]. I can tent with the “relativity of simultaneity” camp which
asserts that judgments of the simultaneity of distant events must change as we move between inertial frames of reference. However it presumes that within a single inertial frame there is one correct judgment to be made.
This is in contrast to the “conventionality of simultaneity” which asserts
In the same frame of reference, one person may assign relations of simultaneity one way; another person may do it differently. Within some limits, neither is factually wrong, according to the conventionality thesis, for there is no unique fact of simultaneity in the world.
Neither position enjoys empirical validation, so choose by inclination.
These two positions are loosely correlated but not identical to the realist, literal account of the world view, vs antirealist view, where all that matters is what we observe.
Now this is where I still find Lisle’s ASC to be at least awkward at the premise. When Lisle states “I will show that the one-way speed of light is conventional. It is something that is stipulated by us, and is not an independent measurable property of the universe”, that statement has him appealing to the “conventionality of simultaneity”. He is careful to phrase that the Bible “uses” the ASC convention. But near the bottom of his article he transitions from ASC convention to ASC model, where he states the ”ASC model implies that all regions of the universe have aged only a few thousand years as we now see them”. There, he has advanced a realist, non-conventionalist viewpoint, namely that conventions which imply an age greater than six thousand years are to be excluded, not excepting the ESC.
