The universe appears "old", but it is still less than 10,000 years old

[Optimistic Mysanthrope]

That measuring that one-way speed may be problematic is not evidence in support of a 10,000 year old universe, which is what the warped one is trying to do.

You're right, it can't. But it can't be used as evidence against it either.

If you measure the one-way speed of light between two points that are, say 100 meters apart, the difference between the synchronization of the clocks will be so tiny as to be utterly negligible.

That's true, but the time between emission and detection would still be an exact match to that caused by positional time dilation predicted by an anisotropic convention. Using that kind of experiment, you have to assume the very convention you are trying to prove - the results are meaningless.

I don't agree with ASC any more than you do but after reading up on it, I can see why any attempt to measure the one-way speed of light is futile. I'm grateful to Statler for introducing me to it. Whether we like it or not, isotropic light is not the only game in town - at least for the time being
