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

[Optimistic Mysanthrope]

As crazy as it seems, ASC does actually appear to be viable. The accuracy with which we can measure the speed of light has absolutely nothing to do with synchrony conventions.

I'm not saying it's correct, far from it. But if there is a flaw in ASC, then it lies within the implications and consequences of such a convention.

One flaw I can think of. Where is the mechanism that suddenly allows light to accelerate to infinite speed after travelling at half c and striking a reflector.

Also remember that Lisles "theory" only posits that light does this infinite speed when it is approaching Earth, nowhere else.

Strange how that happens, as if god doesn't want us to know how old the universe is.

Ok, let me revise my earlier comment. It's totally batshit crazy. The thing is though, it's also totally consistent with experiments to test the speed of light. Arguing against ASC on the basis of light speed is a dead end.

That being the case, it's necessary to pursue the ramifications of a such a convention if you want to refute it. One such ramification is that the convention predicts a bounded universe (at least in effect, if nothing else).
