“ie no difference at all”
again, at least to me, it is very important to be rigorous in the use of language in the description of basic principles of the conduct of the universe.
It is, of course NOT “no difference at all” There will always be a difference, under all real circumstances.
What you mean to say is that in practical terms to humans, and according to our perceptions there is, in a practical sense, “no difference at all”
