Water Jets Cannot Create 40cm Aswan Scoop Marks. Water jet nozzle diameters range from 0.1mm to 6.35mm maximum - less than 2% of the 40cm wide scoop marks Water jet cut faces are typically straight and smooth, not matching the soft wavy texture of scoop marks Water jets cannot cut 4m deep without leaving visible horizontal seams between passes
Why water jets can't explain the Aswan scoop marks: nozzle diameters max out at 6.35mm — yet the marks are 40cm wide. They'd leave straight smooth faces, not the wavy texture observed. Deep cuts would show horizontal seams between passes. The Aswan unfinished obelisk quarry has 40x40cm indented marks that don't match water jet mechanics.
Key Facts
- Water jet nozzle diameters range from 0.1mm to 6.35mm maximum - less than 2% of the 40cm wide scoop marks
- Water jet cut faces are typically straight and smooth, not matching the soft wavy texture of scoop marks
- Water jets cannot cut 4m deep without leaving visible horizontal seams between passes
- The Unfinished Obelisk measures 42m in length with 40x40cm indented scoop marks
- Each vertical pass on 4m thick granite would leave ridges or terraces not seen on the actual scoop marks
