Critique wanted — granular-physics pyramid preprint

Hi HN — I’m looking for technical critique, not promotion.

I wrote a preprint proposing an engineering / granular-physics framework for Fourth-Dynasty pyramid construction. Two focal claims:

A granular-mechanics mechanism relevant to handling ~80 t granite members (≈ the weight of a large whale).

A new interpretation of the internal shafts as engineering features (not mythology).

If you have time, I’d especially value feedback on: (a) the biggest physics/engineering red flags or missing constraints, (b) the weakest assumptions, and (c) the fastest falsification test or calculation.

Thanks for any corrections.
