Let me try again. Earlier you said this:
But this is not correct. Values of ε are from 0 to 1 (ASC) and Einstein selected ε = 1/2 (ESC). If ε = 0 then light travels toward the observer at c/2 which would make the universe twice as old.
By your own logic, ESC doesn’t extend far enough into the past so ESC is falsified. In fact, you’ve gone one better and the Conventionality Thesis is falsified too. There’s only one valid convention and that’s ε = 0. Can this be right?
Of course not. So which convention is correct? They all are! As I tried to point out, you assume that ESC is giving you the correct answer (13.8 billion years) and then complain that other conventions measure spacetime differently.
@r_speir included a reference in which Lisle’s presents his model. The fundamental claim is that ASC is the language of the Bible and Lisle constructs his model from there, including falsifiable predictions. But r_speir doesn’t address those and instead seems to be trying to argue against a convention rather than attempting to refute the model itself.
From the paper referenced by r_speir, Lisle actually uses distant galaxies as support for his model:
“Indeed spiral galaxies nearby strongly resemble those found in the Hubble Deep Field—at the edge of our current knowledge of the universe. The spiral structure is clearly seen in both nearby and distant galaxies, suggesting that they are all roughly the same age as we see them now. This again confirms the ASC model. Even the amount of spiral wrapping seems to be about the same for nearby and very distant galaxies as we see them now—exactly as the ASC model predicts.”
This seems to contradict your claim.
It should be noted that ASC (the convention) allows for, but does not require a young universe. Nevertheless, if there is strong evidence (rather than a tacit assumption) that galaxies are more primitive at increasing distances, then it’s certainly a valid objection to Lisle’s model.
