The host estimates Giza pyramids took 100-120 years rather than the commonly cited 20-year timeline. What strikes them most is the extraordinary precision unique to these three structures, achieved possibly through stone lapping with paste or even concave mirrors for micron-level accuracy.
Giza pyramids built over 100-120 years; precision is the most difficult aspect
EgyptTheory
Key facts
- Host estimates Giza pyramids took 100-120 years to build, not the commonly cited 20-year timeline
- Host identifies the squareness and accuracy to themselves as the most impressive and difficult aspect of construction
- This precision is unique to the three Giza pyramids, not seen before or after until modern times
- Stone lapping (rubbing stones together with paste) can achieve micron-level precision
- Host speculates concave mirrors may have been used to achieve the observed precision
