Can you explain how you know about this "technology?" Can you duplicate it? Can you demonstrate a clear connection between chinese disks and ancient Aztecs? How do "they" know that there were 716 disks found? Where were they found? Only in China or identical disks found on several continents? Out of 716 samples, why do none survive for further examination? Why are there no detailed analysis available? Why are there zero records for the supposed persons involved? Why are there no disks available? Out of 716 disks, why are there no clear, legible photographs, records or surviving pieces taken for sample processing?
If you google dropa discs there are many good pictures of them, and things like them, some of them not the article in question, as well as the usual rubbish that comes with any googled topic.
I came across the technology while studying other topics, became interested about 50 years ago and casually took mental note in anything that I read or heard about since. I was actually looking at what may cause gravity, and because modern science did not satisfy me, I wondered if people of the past had any idea, so I studied everything philosophical, mythical and real about the ancestors. I studied ancient ruins and wondered how they were able to move an eighty tonne rock out of a mountain to another across the valley, etc. I would love to take you to some of those places and show you the obvious.
As I said before the discs had to be made with specific dimensions and out of a specific kind of stone, usually one with a high silicon content.
The fact that the centre hole usually measures the square root of a number, and the outer diameter is the value of that number multiplied by itself, lets you know that if the stone was resonating that the wave of energy would be bounced backwards and forwards from the outside to the inside and back, but effectually cancelling itself out to form a standing wave.
Under certain conditions that occur naturally, governed by the celestial positions, atoms will either want to relax or tense up their activity. By picking the right timing, and patience, the molecules in the stones can be manipulated to jump into another harmonic mode of operation.
This effect may cause the stone to loose its weight, become soft and pliable, give off light, become cold or invisible, all depending on the conditions.
If you look at the old heros and gods as they were wrongly believed to be, from the Babylonians to the Maya, you will see that they carry two items, one in each hand, a stick with usually four discs, and a handbag or cow bell or flower pot, looking object. The original items (of each culture that had been conned and left behind with superstitions) were tools or instruments, later degraded into symbols by those who did not know any better.
