One theory being that harmonic octaves physics were, and have been, used to neutralize gravity at focus points. Like a laser beam directed on an object. Than stone, or whatever, can be shifted and moved just about any where with ease; mountain tops, islands, under water, etc. Even an idea that human flight could be possible with these octave devices. Quite a few ancient myths and even writings, about the use of sacred sounds, some subtle and some very blasting, were in operation. And flying machine have been recorded throughout very ancient history in most every part of the world.
Harmonic octaves (sound) can also be used to destroy. All relating to the law of vibration. Present day fact or fiction is that a sound cannon has been developed that can destroy cities, planes or whatever. All by intense vibration. Somewhat akin to a violent jolting earthquake.
