This week’s feedback addresses the solution to the distant starlight problem by astronomer Dr Jason Lisle of ICR (of AiG at the time of writing—Ed.), the Anisotropy Synchrony Convention (ASC). CMI’s Dr Jonathan Sarfati, responds.
Dale H. from the United States writes:
In an online discussion, I’ve found myself debating the use of ASC with regard to the Bible. It nearly always ends up arguing about if the one way speed of light has been measured, then I get bombarded by dozens of so called experiments that supposedly have proven it, but i then point out all of these experiments have been conducted within the same reference frame as Earth, I won’t list the list I was given. When you apply ISC toward frames with different velocities, paradoxes like Relativity of Simultaneity occur, right? So to blanket the entire universe with one synchrony convention, for all velocities, and all locations, is not possible is it? To argue that ISC is better than ASC, is like arguing the metric system against the English system, they aren’t competing models per se. It’s also begging the question, since they are assuming ISC is correct to argue against ASC, when that may not be the case, it also denies the Simultaneity Thesis, which they continue to ignore. I pointed this out, and this was the response I got. This is a physicist quoting another person in the discussion that responded to me directly.
“Hmm—I think you may be right! I will have to ask if there are any physicists lurking here that can give a definitive answer.
But, if light speed is very high only towards the earth, how is it we observe a younger universe the farther away we look? The farthest galaxies should look the same in age as the nearest … and they don’t.”
“Exactly. The universe looks ‘younger’ the farther out we look. The galaxies are smaller, younger (in terms of star metallicity), there are more collisions per unit area and so forth.”
Another aspect/observation (though I don’t know how this would necessarily work out in an anisotropic scenario), we can see light propagating across the interstellar medium, and in all cases light (or the timing of light reflections anyway) behaves as though light propagates at essentially uniform speed in all directions….
