I thought the pyramids were situated on a granite sheet several meters thick. A natural rock formation, thus the pyramids won't ever sink. Now comes this revelation that piers were sunk below them. What is the true strata beneath the pyramids? Is it soil, sand, rubble, rock, sedimentary rock, etc? If it were granite how were the columns drilled?
The story was always that the site was direct onto bedrock. Often remarked upon that the bedrock itself under the footprint was exceptionally level, and that was deliberate levelling process during construction. The solid monolithic bedrock is limestone iirc not granite. They brought in some granite for the chamber linings and lintels but mainly local limestone in the construction, set upon limestone.

Not piers but hollow shafts, per the video from Chasing Truth.
This is all the output of a tomography code developed by one of the authors. Remember: Garbage In = Garbage Out. Needs a second, independent look.
