"Does a boulder grow disproportionately larger than a grain of sand when they're each lying side by side on the beach? Why should the boulder 'fall' faster than the grain of sand when the entire frame of refererence is rising up to overtake, meet and strike it and the grain of sand?"

That's the point to my questioning your position, RP. Your explanation to me implies that the earth would cover more space than the boulder and the boulder would cover more space than the grain of sand. I never said that one or another would be larger or smaller, but asked why you said the larger covers more space than the smaller.

My first question was related to aerodynamics, whereby a crumpled piece of paper and a flat piece of paper would accelerate at different rates. This is empirical and would not be the case if all particles are expanding proportionately.

Then , following the implications of your explanation for the discrepancy, like objects of different masses would have to hit the ground at different times, but empirically they don't.
