Bear with me, my theory...
Everything has a frequency, you, me, rocks, plants, sound etc. Sound has a frequency range that can affect different matter, its frequency changes the frequency of another thing, like an opera singer can shatter glass by hitting a note, the breaking is the altering of the glass's frequency.
Back in the 20s-30s a German archaeologist was in Tibet where he met some monks, the monks were using 'singing bowls', large metal bowls that have the rim rubbed (oo-er) with an object like a pestle, this emits a sound, pitch or tone of a particular frequency. The monks showed this technique in altering the frequency of stones using sound and were able to lift large stones with their fingers.
Recently the US intended to use sonic defences at its embassies around the world, if attacked these would give off an ultra low frequency that renders those in close proximity violently ill. NASA did research into it years ago too.
The influence of sound over matter, Cymatics..see vid
I believe this is how the stones were both cut with precision and transported and lifted to build the pyramids.
Now I have to work out what made the sounds
