I think the point of the person you're responding to is what are the practical consequences for future scientific and technological leaps if this is accurate. Does that make FTL travel possible? Does it predict an outcome for the fate of the universe? etc.
i dont even mean big things like that. I'm more wondering, is there any experiment you could in theory do that would differentiate between the two cases? what does it affect? anything?
for most problems and perspectives it’s an irrelevant distinction
