I mean if this was true then the laws of physics would also have to be constantly changing so that shrinking objects would behave in the same way at every scale, instead of having all kinds of changes related to surface to volume ratio, differences in behavior of forces at different scales/distances etc. And if you need the laws of physics to change constantly to explain a theory, and the theory is only provable/observable from outside our universe, it doesn't have any usefulness to us, other than as an intellectual curiosity...
