Phonons and Anti-Gravity

Bonehead, they could be on to sumthing (too many ridiculously big & heavy stone artifacts from the edge of prehistory exist to summarily dismiss such options!), but the evidence will become more compelling once experiments get moved out of superfluids, extreme conditions/temperatures and the like. Plus I suspect we need 'better' sound. Like a sacred song or chanted spell REMEMBERED from the days we purportedly manipulated gravity with acoustics. (Folks who do remember are not telling.)

Reminds me of Native American shamans where part of their initiation was jumping off a mountain (with landing in one piece of course vital for career prospects). Could they have known a song which will safely carry one person?
