In my on-going research for a book that may never get written, I discovered that researchers have been using sound frequencies to levitate physical objects. I stumbled upon this fact watching an interview with a man who has traveled to indigenous peoples around the world to interview them and learn about pre-flood civilization from them via their oral ancestral histories.
According to this man, at least 3 of the peoples he visited told him, completely independently of one another, that massive stones were moved into position in some megalithic rock formation or pyramid (I’ve just ordered his book, so I don’t know the details at this time) by human-like beings who used their voices to hit a certain frequency, which levitated the massive rocks. The man who was interviewed cited an experiment by the Princeton Engineering Anamolies Department (now closed down) where they found a piece of rock of exactly the same composition as the rocks used in the ancient megoliths or pyramids, and themselves successfully created a frequency that levitated the piece of rock.
Although this is not the same as a previous post I made about speech creating toroidal fields, acoustic levitation is a real phenomenon, and I’ve also found several patents related to it, the oldest one I found being from 1979. The technology has been around for some decades already. Of course, at this point, people are only able to levitate small, light-weight objects.
