Harp is a large version of something found in the pyramids. Redesigned on paper by a man far ahead of his time. It has MANY uses, if used (built) correctly. Plainly put, it controls vibrations, therefore, it controls everything, as nothing is real, except vibrations.
Look all that up for more info and disinfo.

By matching the resonance of a thing you can vibrate it. I am over simplifying but it is simple really. Stand in front of a guitar and hum or sing an A and the A string will vibrate. The frequency of a tuned A string is 440 vibrations per minute. Therefore if you pick an A string it vibrates 440 times in a minute. If you sing an A, your vocal chords vibrate 440 times a minute. So, by matching what a "thing" vibrates at, you can MAKE it vibrate. Earth's frequency is or always has been 7.8, a very low frequency, to low to hear and the lower the frequency the more power it takes to reproduce it. So, can a machine vibrate the earth? Do your homework and you tell me.
