NKJV Joshua 24:27
And Joshua said to all the people, “Behold, this stone shall be a witness to us, for it has heard all the words of the Lord which He spoke to us. It shall therefore be a witness to you, lest you deny your God.”
Why is this ponderable?
Although most Biblical Scholars believe that Joshua referred to this stone as a symbol of their covenant, recent scientific research indicates that it may have been much more than that...The EM Spectrum exists naturally, occurring as a part of our natural environment. It should come as no surprise that ancient civilizations and cultures possessed some knowledge of this naturally occurring “tool”, especially acknowledging the ancients’ intimacy and inter-dependency with nature.
Advanced ancient civilizations used the resonant frequencies of sound as the source of energy. Tesla proved that specific sound frequencies broadcast from a tower created pure electro-magnetic energy. Measurements of the circumference of Stonehenge indicate that it was constructed to resonate at the frequency of10 hertz which is the Alpha Wave frequency of the human brain.
Cymatics is the study of visible sound and vibrations. "It is important to understand that although sound is invisible it actually carries structure, both in air as well as water."

"When we study the geometry of sounds visually, using the CymaScope, we see that they include many of the mathematical constants of the cosmos, including phi, sometimes known as the 'golden mean'. This ratio is approximately 1 to 1.618 and it is found in all living things. Cymatic geometry is based on definite angles that form on a membrane 'imprinted' with the sound vibrations, thus allowing us to observe them cymatically.
Pure sounds are devoid of harmonics and do not feature the rich complexity of a musical sound. An example of a fairly pure high-pitched sound is an organ pipe, which causes air to spin into a vortex. Such pure sounds contain the all important phi ratio and they create sonic scaffolding that, we believe, organised, structured and triggered life."

Tesla said that the core of the earth rings like a bell. Perhaps Biblical Scholars need to ask for whom that bell tolls...
