The presenter uses the summit alignment to support a spiral-ramp hypothesis. The cited research does not establish that construction sequence: the gravity report considers more than one internal structure, while Hatnub documents quarry haulage rather than a ramp at the Great Pyramid.
The claim in context
The inner blocks at the Great Pyramid’s flattened summit, compared with the surrounding perimeter blocks.
History for GRANITE argues that their clockwise alignment reflects blocks laid against a spiral ramp. The claim concerns evidence for that explanation, not proof of a unique ramp design.
The 1987 survey models density variations inside the pyramid. Its authors consider both spiral and semi-vertical structures to explain alternating lighter and heavier zones.
A density reconstruction does not directly identify a construction ramp or connect it to the summit block alignment.
