There are a number of legends surrounding the building of the great megaliths from antiquity with regard to their construction without the benefit of heavy modern machinery. These legends mainly involve the use of sound vibrations which allegedly made multi-ton stones easier to move as if they had been rendered lighter. Other accounts even claim that these colossal materials were made to actually rise in the air against gravity. It is presently unknown as to whether we can take these anecdotal accounts at face value, if they are exaggerations of real events, or if they are simply made up fairy tales. One might wonder why sound seems to be the common thread in these accounts. Even more so is why anyone would think that sound could even do such a thing as render a heavy object easier to move in the first place. Interestingly, modern experiments and calculations have suggested that sound vibrations or rather phonons, the quasi-particles and quantum mechanics representations of sound, carry negative mass and thus negative gravity. In other words, phonons traveling horizontally through a mass are weakly repelled and deflected upward by Earth's gravity. Since phonons exist only within their medium of travel, this means they might be able to transfer some of this sonic "buoyancy" to that medium, in effect countering some of the material's positive mass. Albert Einstein's E = mc2 formula shows that though energy and mass are interchangeable, the high proportionality constant of the speed of light squared means that it takes an enormous amount of energy to produce mass. Generating such energy might seem impractical. But can molecular resonance be the key to circumventing this problem? Could it be theorized that precise molecular resonance might be able to develop enough energy potential over time; effectively converting enough sonic energy into mass, in this case negative mass, that it would significantly reduce an object's weight or even cause the object to levitate? And if so, could the ancient builders have been aware of this proposed property of sound as well as the property of acoustic lubrication as demonstrated in earlier videos?
